- This is very exciting, and I could not wait for the first full day of charging the battery with the Hyundai Shingled Solar Panels on our new West Roof. This is a 2s5p setup with 4kWp power output.
I was really surprised to see what these panels deliver in different conditions during the day. Comparing this with the Victron MPPT calculator... I'm already impressed.

Thanks Andy
I am happy to see I am not the only one having fun watching Victron's app . This is like magic. A gift from God.
Awesome. Bout time. I been waiting to see how the install went
Congrats! Well done!
Thank you!
Thanks!
NICE! Those panels are doing some work!!!
What an amazing “power” installation 👍👍👍👍
Yeah, it is HUGE!. Wait for the full installation...
Great output for the conditions.
Hi Andy,
I remember when you made the test of the SEPLOS MASON DIY 280 kit. I bought 3 of them following your test. I just received them today (after 2 months waiting for delivery in France). I can confirm they've listened your suggestions for enhancements in your video, or at least some of them because now, everything is in a box inside the box. No more parts in plastic bags or moving inside the case: all is well oragnized!
Thank you for your very well done work/videos Andy. Learning from you every day 🙂
great, how much have you been charge for shipping and taxes ? if you don't mind
Nice installation! Can't wait for the summer to arrive here in the Netherlands again. 🙂
Luckily we can compensate our short dark days with your sunny videos!
I live in Finland... Still like 5 hours sun a day... for 2weeks.. then darkness to February...🙈
@@jensehnstrom That's a lot of darkness you can't cover with solar or a big battery.
Thanks a lot!
Fun to watch these videos, I'm getting HiE-S430HGs installed next week.
Hi Andy, that's awesome. I can't wait to see the full plant in action.
However, I have a comment on the MPPT chargers and their temperature.
The manual clearly states for temps:
Operating temperature: -30°C to +60°C (full rated output up to 40°C)
So it will throttle down when reaching 40°C. Since you live in sunny hot Australia, you might see that in the summer. I put some temp controlled fans on the things, because they reach 40°C quite quickly at the surface.
heck yeah. you maxing your charge controller. its gonna be impressive when all 4 strings are running. I finally got my battery banks top balanced. I had 1-2 cells in each bank hitting max on my settings for JK bms. Took 1 week almost and now all charge and discharge close to each other. I understand how you feel when things are going good. cant wait to see your roofs filled and you filling up each day if its possible.
It's going really good now. The power production problem seems to be solved, even with the trees 😊
Very impressive solar panels! I can't wait until they come to the US. I have some 2kW microinverters I want to try with them. Wow!
Do you have a lot of shading as well?
Based on my experience with high wattage solar in sunny Jamaica , divide the 4000w string into two and use two of the 70 amp vectron 150 charge controllers and you'l be fine.
Victron's chargers are rated to full output with ambient at temperature of 40c if correctly mounted. After that they will throttle their output to keep operating safely. They will get quite hot, but it's perfectly normal. None-the-less I have placed a blower pointing across my charger's heatsinks to give them a bit of assistance. It's not blowing a gale, I have them slowed to the point where they are almost inaudible and that does the trick nicely. Summer temperatures here reach 35c and higher, none of that cool Brisbane weather.
Yes, that is correct, we can see it outputs only 3.7kW, so already throttled. A fan would not make a huge difference (tried that) and I have too much power in summer anyway.
@@OffGridGarageAustralia Andy here is the benefit of 85A version of mppt. It has bigger heatsink, so better cooling.
@@stanislavmlcuch2085 that is true. I have now capped my MPPTs to 60A. Too much power...
@@OffGridGarageAustralia When you are pulling maximu amps from mppts sooner or later they reduce the power. Solution is to put there 120mm fan or buy mppt with bigger heatsink. Friend of mine has around 40kWp and recommend me to buy bigger mppt than I need just because of this.
Adding a fan will also increase lifetime of the MPPTs, if they are maxed out such a long time..
I followed along all day too, as you know. Its one thing geeking out on my own data, but I was fully "in" for your new system - haha, your morning is my evening and it was compelling for some reason. And the next step that's already happened ;)
Send me your link, I want to spy on yours too 😄
I should make a website where viewers can post their VRM links.
@@OffGridGarageAustralia I don't have a VRM yet, it is on the future upgrades but my MPPT is an Epever. But there is an interesting video on my channel "How bad is the solar winter - UK vanlife " or something like that. With the "stat geek" thumbnail. But i will get 2 x 70amp Victron MPPT and a VRM at some point.
Heya, it looks to work good can't wait to see wen all panels are installed
Fist charging 😁 sounds brutal! Keep up the good content Andy! Loving the upgrade
It was late... 😊
Hi Andy,
I really enjoy watching your channel a lot! Thank you for your efforts to show every detail, that’s so valuable! I wish I could be your neighbor in sunny hot Australia to visit you with a couple of beers from time to time. You are my ESS hero.
Best regards from cloudy, wet and cold Germany 🇩🇪
Dominik
Love that you are making progress and sharing it with us. I have to admit, I'm a little concerned. We always talk about the gernal rule of using an electronic device at 80% of it's rated performance. Safety and security are the stated reasons. Don't take chances.
You will be running these SCCs at 100% for hours/days? Please get the larger controllers and be safe and ready for the NEW shed coming next year. 👍☀️😎💥
As I said in the video, they are made for that. I guess the maximum rated capacity is already to 80% of what they can really do.
Well done 👍
Thank you 👍
@@OffGridGarageAustralia hey Andy out of curiosity sake what do you do for a living?
Nice installation Andy👌 That will be a lot of Amps
Awesome Andy- with all that power you’ll be able to run a decent aircon if you want and have a nice COOL off grid garage 😊
Yeah, thinking about it. We will get new A/C in the house and I can re-use the old on from there... Battery is now full at 9:30am...
@@OffGridGarageAustralia your maximum input will be off the charts Andy!
"COOL off grid garage" that sounds really good
I think now u would need few more batteries with that large system. I know ur going to put up the ready-made battery pack. Great work.
The power problem seems to be solved for now... 😎
I'm uping my 80A with two 150A, feel like I should future proof most requirements with that
Effectivement c'est assez impressionnant comme production, intéressant de tester avec un contrôleur de 80A ou 100A afin de ne pas être limiter en production par la sécurité probable du contrôleur MPPT de 70A... Brefs merci ANDY pour ce partage.
Dear Andy, you got breathtaking 50 kWh´s on your first day of fully installation. But yesterday, without charging the EV, it was almost 20 kWh`s.
That`s exactly what i observed in my solar installation in summertime: without a big "energiesink", you will not get what you could!
So, without any doubt, you need more batterie capacity yet.
Will be exciting, to follow your new ideas and decisions - and we all will enyjoy this! 🙂
On the other hand: in wintertime you earn just a 10th of the summertime harvest, so it would work fine with the momentary batterie capacity...
Yeah, that's exactly what happened. But more batteries won't help if you don't use the energy somehow. It helps you once until they are charged as well. Then, you will be in the same situation again.
Wintertime will be the interesting season for sure.
@@OffGridGarageAustralia Thnx 4 response, you are right Andy.
For full autarchy, batteries must be big enough to reach for the longest average time of rainy days, you usually have in your area
wunderbar
When you add up all the hardware to operate Victron it becomes a very expensive solution. I,m used the MPP 11kw inverter with built in 2x 150amp MPPT converters making the setup and wiring very simple.
That's part of the test and experiment I'm doing. MPP inverters are... well, let's say I know a few people who have them.
Clipped your solar already. Clipping is good for the winter months. I bought a cheap charge controller rather than clip the power. It makes me cry when the batteries are full and the inverters turn off the panels. I might buy a water heater to dump all the extra power as I don't have a Teslander. Lol
Yeah, summer is simple. Lot's of power right now.
The hot water connection is in planning as well as a pool heater. And a fridge in the garage 😊🍺
Andy put some fans behind those charge controller heat sinks, good insurance
such an impressive system. I think I would be felling some trees ;) Really looking forward to seeing the whole system up and running. 👍
He likes the trees, he doesn't want to cut any of them down
That is the experiment I'm doing. Instead of spending $10k on cutting down these trees I invested this money in solar panels and can leave the trees as they are.
@@OffGridGarageAustralia I think you are going to have more energy than you know what to do with. At least in summer.
@@OffGridGarageAustralia yes, it will be amazing when you have the full system. They are doing a really good job of the install. Did you get them to add more 'spray' on the exposed copper earth/ground wires? ;)
@@mw0lge All these connections are under panels and not 'exposed' as such. They will come back to finish off some other tasks and fully commission the system (labelling, cabling, ...)
Get the 150! Victron will probably give you a good offer...bigger models will also probably handle heat etc. better than maxed out small models (which you really shouldn't do)
It`s a quite good idea, to break down a complex system to smaller, identical, units in a higher count! This redundancy makes ist easy to compare und change in a case of failure or in a case of testing and comparison parts ans components.
I go with Andy in exact this way!
Awesome
Wow Andy, this is going to be so awesome when it is finished. So people have asked if u will ever get ur batteries full, I am guessing you will be able to fill up to 2 of ur 44kw batteries fully (on good days), & 20%-50% on not so good days and poor weather, does that sound near the mark? Here is another prediction; I can see at least another 44kw of Lifepo4 cells on ur floor in the not too distant future. Cheers
WOW 260 A !!!
YES!
Hi Andy. Great work indeed, been watching your great educational content (in no particular order). Great work indeed. Just a question of clarity from my side; does the west roof mean that the panels are facing west?
I don't know if those trees are protected and I am full against deforestation but those trees could use a little trimming, don't cut them just make them a bit shorter and maybe get a little off the sides too, not only to reduce shading on the solar panels but to reduce the danger those trees could cause during windy days and storms
I topped 2 trees so I would have no shading from them. I live in Michigan USA west side and we have so many trees around. I am gonna plant 2 new trees in there place even though they are just topped. thinking fruit trees.
ua-cam.com/video/nS72GpEO-zA/v-deo.html
~45 deg celsius outside on the housing means around 60 deg celsius inside the chip. That is 100% OK
Hi Andi, almost 240 amps/ 13.8 kW you got on Monday at 1:15 pm already with completed installation. An upgrade of your batterie is planned? Now, at 6 am, your batterie SOC is almost 80%, where you want to let all the watts? I guess you have to go some extra miles with your Tesla 😉
This Hyundai panels are amazing good☀️👍☀️
Stay safe and stay chaaaaarged 👍
Yeah, I'm a bit overwhelmed with all this power now to be honest. I was never expecting that much energy. I can easily fill up the vehicle twice a day now 😂
Wow, that's a nice yield per day. Makes driving the Tesla for free! (And all other stuff)
Wait, there is more 😄
If shading problem is very obvious; try to re-arrange the "left" panels to the right hand side of the roof.
Andy I would be interested to know how the 70 Amps are divided over your 3 batteries. As I remember they are of different capacity. THX!
Andy If I may, now you have a lot of old panels. Could you do it the test with one long string vs. paralel string? Maybe 6 panels in series vs. 3x2, just to compare the power production in your shading condition.
you need a different MPPT controller to add 6 panels in series, as the open circuit voltage would exceed 250V, and these victron MPPTs can only take 150V max, and give out 70A to the battery, hence their name! More panels in series is always worse for partial shade conditions.
Hi Andy, does your Multiplus II hum when inverting? and if so, how loud is it, thanks.
I used Victron's MPPT calculator setting up my system. 2.4k panels 6s4p, .. 150-70.. under 100% .. well within limits. ... I went with the 150-85...... according to them for my local, peak, in summer, I was producing 10-15% more than they calc'ed, and, my panels are FLAT on the roof of my TT. I will soon be adding 1.8k more panels, same 6s4p, I will be using another 150-85, .. Why you may ask?... Redundancy/backup .. Yes, overkill for the new panels, but, should need arise, can be swapped to the main array.... 2 is 1, 1 is NONE......
You cannot have enough panels. There is always a cloud around.... 😊
Andy do you like these panels better than the old ones I only have 3 x 170 watts good video again 💞
If you want to test, ifva bigger controller will make a lotbof difference then you can put two controllers in parallel. And you have some extra for teeting, Right?
You're gonna start doing flips once the whole system is installed and you see the peak generation. Its nice to see it do so well in the morning... that's the claim-to-fame for those panels, after all.
Full sun probably is more around 3.5kW at 5:20-ish in the video. You are getting extra from the brightness of the clouds nearby. There will be times when that happens... when the sun peaks out from behind the clouds and you get full sun + bright clouds at the same time. The system will cap-out for a minute or two.
At this point you really need to start looking into high-voltage string inverters instead of using these little low-voltage controllers. I can't say how they would compare, though... having more, smaller inverters is always better in variable-shading conditions, but high voltage strings have far lower wiring losses and are just easier to manage.
edit: Well, in your case, charge controllers, not inverters.
I've got the other smaller system running now (3kWp with 8 Hyunday panels, 400W/ea) and it produces a permanent 3.8kW under normal sunny conditions. Over 4kW with these cloud corner situations. They are producing far more than they are rated for.
Longer stings are not good for these conditions and far less effective. I think this is the most optimal solution so far, even it was a hell of a job to cable all that.
Hi Andy, since you are maxing out your MPPT with 70A charge now, are you not worried about your 63A DC breaker connecting the charger to the batteries?
Victron has RS models of MPPT series, those put a lot juice.
They are only good if you can use higher voltage strings of panels. With shading, that not a good option though. You want parallel strings.
Awesome Andy, keep it up
Is the FIST charge deliberate or simply a typo?
Kudos 👌👌👌
It was like 12am when I uploaded and did the description 👊
@@OffGridGarageAustralia it could happen to anyone but then, a caption like FIST CHARGE FROM THE WEST ROOF would be great. Maybe on the next roof install 😜.
Do have a time doing this for all DIY enthusiasts.
👍
Can you make a wiring diagram so we can see how you get only 80 to 90 volts with 10 panels ?
On what setting did you set your big circuit breakers on the battery again?
Did you calculate the maximum charge current, which you would get if all roof systems are up and running?
I think you need to reevaluate the trip setting on those breakers, because not only consuming current can trip them, but charging current as well...
Oh, what I totally did forget: Didn't you install 63A breakers for each charge controller? Their temperature trip could rob you of the fun eventually, above 80-85A at the latest...
Current is current, does not matter if it is charging or discharging. I have set them to 80A for each bank and 250A for the main breaker.
Yeah, the MPPT breakers are 63A only. I really did not expect so much output of these panels.
Dang Andy thanks for the outstanding test report, that is amazing! At 7:00 could you add a second a second charge controller in parallel to keep the 70 amp controller from throttling to parallel charge the same battery bank (with an isolator if needed), or to charge a second battery bank? Also, can you give us an idea of the installed cost of that 10 panel string? I think that would be perfect for my needs.
Just wait until the whole system is in action 😉
@@OffGridGarageAustralia So much fun! Looking forward to it, Es wird großartig! (If that's the proper phrase in German).
Andy, can you make a review of shingled panels vs bifacials... It would be interesting.
I don't have bifacial panels, sorry...
Are you going to connect the Seplos batteries on CanBus after all the panel installations?
Yes, that is the plan. Maybe even the other batteries...
Hello
Which is better Hyundai or Longi or Jinko panels please reply
cheers mate! What IR camera were you using? FLIR one pro?
Yep, that's the one.
Have you gotten the new SEPLOS firmware for your Madson battery kit BMS ?
Meine Energiewende has released a video yesterday about the firmware .29 solving at least some issues you had faced like shutting off balancing once charging stopped.
Hope you will examine it too if the balancing is working now and we can avoid adding an active balancer at least for smaller batteries.
The elejoy checker for 800W panel is also a lot better. Got mine in August and was able to check the modules for max output.
I just left a longer comment on his page.
The new FW 2.9 does not change the behaviour of the balancer unfortunately. His test was a bit... When he stopped charging the balancer seemed to 'work well' but in reality, the overall pack voltage decreased which pushed all cells back in the flat area of the curve, hence the voltage delta decreased as well. It looked like the balancer is working when the cause of that was the decrease of the overall voltage.
The 2.9FW has no visible changes to function of the BMS as far as I can tell. The balancer still sucks!
Yeah, I really like the display of the Elejoy Panel tester. it's a great update from the previous model and well worth the money.
Flying Foxes, cool I wish we had them!
You probably don't really want them mate. They can be quite a pest. Colonies of thousands. Shit everywhere. Huge splattery shits everywhere that makes good paint stripper. Everything eaten, esp fruit trees. And they can harbour nasty viruses. A few are OK, but the big colonies drive us nuts. Especially the farmers.
This is only because humans invaded their habitats.
@@OffGridGarageAustralia Very true. We manage to live with them. I also hear the same about raccoons (for example) in USA / Canada. They have to live with them but they can be pests, so I hear.
@@Browneye2566 we have heaps of raccoons in Germany too. They find food in our rubbish and a warm home under our roofs.
@@OffGridGarageAustralia How many possums do you get up there Andy? There's heaps in the southern highlands. We try to put possum boxes in the trees so they keep out of the roof.
Like you we have lots of frogs, but my favourite are the geckos that come out on the walls of a night chasing bugs to eat.
I needs some beers also ! LOL....I mean Diet Mountain Dew !
If you max out your charge controller can you add another one and wire it straight into the Bus Bars? So both the maxed out controller and the new controller both are feeding the bus bars?
I have 4 of these controllers, yes, that is possible but not from the same solar panels. Each controller will have to get its own panels.
What is the max. current you are expecting at full sun and without being limited by the charge controller? Maybe even more than 85A?
Around 50A from the solar panels which is then 80A into the battery. Just a guess though what I would expect from these panels. It's not worth going for a bigger controller but would be cool to test it and see the real numbers. Once the other roofs are connected, I will have too much power anyway, so a bit of clipping is OK.
I like it
Me too. I'm really impressed with these panels.
the low voltage input and limited output current on affordable victron made me throw victron away and went with 5kw phocos hybrid inverter. @450v input voltage. the solar panels cable sizing becomes easy and 4mm works. For battery cables 1.5 meters 50mm cable works and cheap enough.
🎉🎉🎉
That SPAT didn't look calibrated! Need to calibrate another one!
But it worked! 😂
i smell a really big battery incomming
But how big is too big?
@@OffGridGarageAustralia idk, u are the AMP whisperer, i would aim for at least 3-4 days storage without sun
hi Andy why don't your mppt charge controllers compete and stop each other from charging ?
You can have as many controllers in parallel as you like as long as they all have their own panels. They only see the battery and don't interfere with the other controllers at all.
Du wirst Dir sicher noch eine RC- „Schneeraupe“ mit Microfasertüchern zum Reinigen der Solarpanels zulegen. lieber Gruß
Reinigen macht keinen messbaren Unterschied. Hab ich schon mit dem alten system getestet.
@@OffGridGarageAustralia He he 😀 das wäre bei mir auch herausgekommen 😀
WOW!!!!! Amazing results for not perfect conditions. I.E. shading and not optimal angling. Very impressive for just 10 panels. You will definitely have issues with your charge controllers being constantly maxed, witch truly isn't good for them, as well as your 3 bms units might want to blow up from the mass current that your small power plant can produce. 🤣
The MPPTs can handle that no problem. As I said in the video, they are designed for 130% over-panneling.
There will not be a problem. Currents will split over all batterystacks, so the bms should not get an issue. If there is really a problem its also possible to limit the charge current of the solar chargers. I am running a 14kW Peak installation in north of germany. 2x15 panels (5 in series, 3 in parallel) south, each on a Victron 250/100 MPPT - in summer each of those can deliver 5,5kW (5kW official rating). And one 6 panel string heading east also on a 250/100 MPPT (can add some more modules there). Now in November its still possible to run full on solar, but this november is surprisingly sunny.
@@alexanders3795 I have already limited the output of the MPPTs to 60A now. I had over 260A once one the main breaker is only 250A. To scary...
@@OffGridGarageAustralia That's true. In that case the main breaker is too small ;-) - but as I know from your videos there is always change - as in my installation too 🤗 Solar power is addictive
If you are going to be hitting the charge controllers that hard you want to optimize their backside heatsink air circulation. They will back down their production if they get too warm.
Just wait for it...
@@OffGridGarageAustralia I mounted my MPPT`s on a 20 mm thick aluminium plate, which works really fine (two 150/45 MPPT`s on a 30 by 40 cm plate) They don`t even get warm under maximal load
Wow. We thought we were doing well with our 750 watts of panels on our yachts arch charging 400Ah of lithium. You may need a bigger garage or another battery car 😆
How much storage capacity do you have in kwh?
44kWh at the moment in production. Another 30kWh in planning....
Andy, now you can think about how you "burn" 80KW every day in summer. 😁
Optimiser on panels ?
Nooooo, never.
Hi Andy! What about the trees around? Is it possible to short cut it little bit. I’m Ábel to do it 😉
Martin
Also Andy, wenn die PV fertig installiert ist, dann kannst Du eine eigene Aluhütte betreiben und hast immer noch genügend Strom übrig...
Moin,
die Installation ist ja schon abgeschlossen.
Zwischen 12:15 und 12:30 werden die MPPT-Regler richtig rangenkommen, da kommen zwischen 13 und 15 kW vom Dach😁. Andy kann den Strom gar nicht schnell genug verbrauchen, gegen 13:00 ist sein Speicher regelmäßig schon voll🥴
Andy, I would like your opinion on lithium build I'm going to put together. Its for high power car audio (90A average 600A peak) I'm going to use 48 Headway 38120 HP 3.2V 8AH LIFEPO4 cells(12C discharge / 4C charge) and 500F in capacitors (to handle peaks and car starting) It's replacing 2 x 100AH AGM's and I'm repurposing the 500F in caps.
In your opinion is a better idea to set up 2 x 4S6P and 2 x 200A BMS's (B1A8S20PH) in parallel or a 4S12P and 400A BMS?
I'm leaning to the 2 x 4S6P and 2 BMS's myself, to limit the amount of parallel cells.
Do you still feel the same as you did in your Jun 10, 2021video "Parallel Battery Strings - worst solution ever?" ?
thank you in advance.
0:55 2.5 panels giving 1KW @ 10AM. WOW! not bad.
Do you have an Irradiance meter?
Yes, I have. But where to measure? On the shading part or sunny part?
I have in usual 300v for approx 12amps. Don’t you think it’s less dangerous? Isn’t it? My cables are 6mm. It cost less and ne et heating
Gode videoer Hr. Andy Kan du sælge noget af din over produktion til energi nettet i Australien, vi kan DK men ikke en god forretning ?
Do I really need another, larger charge controller? Just go buy it (Them).
Feed the addiction.
I don't need one. Hence I said it would be good to have one for a while to test and see the difference. But I think, I won't need it as I have far too much power now...
How have you connected up those panels with that shading in them? Surely one shaded panel will bring down the rest?
I assume this isn't a simple single string in series?
Edit: you literally answered the question as I finished. 2S5P
So those couple panels in shade are not affecting the others.
Got it. 👍😀
That's what's good about these Victron controllers. You can shove quite a lot of power through them.
Hybrid inverters are very limited to input current. Big voltage range, but no chance to parallel up any panels.
Phil, this is not one string, no. It's a 2s5p setup. 2 panels in series and 5 strings in parallel. It's all in previous videos. I chose this setup because of the partly shading I have on all my roofs.
@@OffGridGarageAustralia yes, I saw and said in my comment.
Nice set up! Do you back feed to the grid, if so how much do you get paid per kw, Or is it a real off grid system, what do you do with 80 to 100kwh of power per day?
AFAIK Andy does backfeed... but with a completely different setup on his house (he's locked into a contract so can't change anything there). This setup is "off grid". Having said that, this system takes a lot of overhead out of his house setup and so this system 'vicariously' backfeeds into the grid if you get what I'm saying. I think he's running a pool pump, lighting and charging his Tesla with the power.
Ok. Nice, at least in the winter he will also get a decent amount of power from this setup
@@Jmax777 Yeah it looks good. I'm currently building a completely off grid house and am watching what he's doing very carefully..
It's the Off-Grid Garage, mate 😂
Cut some of the tree top off to improve you solar numbers due to shading
nice 400W module and 540W output i need more sun in germany...
😭
Shading is really affecting your strings. I would suggest you first trim those trees and wire your panels in parallel in order to reduce the string impact. Otherwise divide the shaded strings into different victron mppts. Those Shaded mppts will help the unshaded mppts to work better. If you are able to solve your shading, buy the 450v victron mppts. they have multiple pv trackers and will still work with your victron ecosystem.
I agree that would help but in past videos, Andy has stated that he does not want to trim the trees. Instead, he is going with many panels knowing he will get shade. He could certainly get more out of the system with additional controllers. It is a trade-off of the cost & difficulty of adding controllers vs the benefit he gets. (His general approach to date is to add lots of panels).
yes, I concurr. Put the shaded panels on one string. And the others - which are always in the sun - on the other string of your mppt tracker.
I don't think he needs to... it looks like more than enough Amps are charging his system. Albeit if Andy wants to expand the battery it might be another matter 😄
He has a 2s5p configuration with only 2½ being shaded, with the amount of planned panels in his array, he will definitely get more than enough yield.
Andy is an environmental protection activist so trimming the trees is a no no..,.
@@IkkjeDus I am doing a similar installation 4x eve 280ah 48v batteries and 16x365w qcell panels. It will basically be an offgrid installation. You want all the power you can get specially on cloudy or multiple rainy days hahaha
Why are you running your strings at such a low voltage? seams like a real downside on cable size and amount of cable. is there some max voltage regulation in AUS i'm not aware of? i'm running like 200Vdc on the strings here.
Because of the shading. This is perfect for such scenarios. Yes, more cabling effort but also far better efficiency and control over the system.
@@OffGridGarageAustralia It`s a quite good idea, to break down a complex system to smaller, identical, units in a higher count! This redundancy makes ist easy to compare und change in a case of failure or in a case of testing and comparison parts ans components.
I go with Andy in exact this way!
need a bigger battery for storage power
Stupid question. Your pulling 1kw from your panels. What voltage is that?
It's in the video. It's a 48V system and the panels have around 80V in their mpp.
Like# 26!
Andy, I know you like your trees, but a small amount of trimming your trees would make a huge difference..
Why? You still don't understand the purpose of this experiment. Look how much power we're already getting.
I think he could leave the Tesla run on a Dyno all day and still charge to 100% without any tree trimming, when the installation is finished.
@@evil17 That is exactly right.
@@OffGridGarageAustralia Months ago, I thought I should start a Fund Me $1 every time someone suggest you cut your trees, I reckon I could have a setup like yours in a short time just from that.
@@evil17 yeah, it's insane how many people consider this as a solution. You could have financed you system from that for sure 😁
Clearly if you have too much power, you need to run a refrigerant cooler on the MPPT's.... can't lose? :D
🙂
I much prefer my SMA Sunny Boy strings which can put, say, 10 panels in series. Max amperage is 15, but it can handle 4.5kW (throttled to 3kW) for each of the two entries. But I guess you'd need an SMA inverter for that.
That's not gonna work in shading conditions like I have though. There is a perfect reason behind this design. I could have stringed all panels together as well but the output would be far less.
@@OffGridGarageAustralia Ah, yes, of course.
My setup is obviously different with mainly vertical south-facing walls (northern hemisphere...)
Can you please repair the vrm link? The link in the last Videos are broken. THX Nice Work Nice Vid
Works for me... Did you use the one from my website?
@@OffGridGarageAustralia I used the S.P.A.T one from one of the last Videos and saved the opened Website. I found now the link on your website and it works. Thank you Andy, Stay Charged und bleib Gesund!
