Now that you have done this video what is your view on the inergy kodiac since you did the review on it in August 2017. Do you still think that the Kodiak is the best option for traveling and using solar or do you think that building a system like this would be more affordable plus convenient for space?
Good day Will, will a 60ah lit-ion battery be enough for a 1500 what inverter. Grant it would be used as a stand by solar generator for need be scenarios. Thanks, hope you are well
@@milvolts1 Probably not. You need to find the discharge rating of the battery. I doubt that it can handle that inverter size.
Will Prowse RV Living and Off-grid Solar , what size inverter do you think would more practical or realistically? In your opinion..
Hello youngman, I am from South Africa and want to share with you. 35 years ago we started installing a solar system at home. Think about it, 35 years ago Solar was still brand new technology and extremely expensive. We installed the biggest panels we could find at that time weighing in at 85W each, we installed 3. And that is what I want to talk about. South African sun is very similar to where you live, in other words harsh at best of times. These three panels a still on the roof after 35 years and even with the harsh conditions it maintained integrity surprisingly well. The voltage on the panels when new was 22 Volt ( I know it sounds odd) @ 85 Watts. The Amps delivered at that time was 3.8 A each. Now after 35 years the cells have degraded a little. I tested the panels last week and was surprised to find the deterioration was only approximately 4%. If my math is correct the supply voltage is still 22Volt @ 3.7 A. The manufacturer of these panels do not exist any longer if memory serves but it was BPSolar SA. Just thought to share and show that if you take care of a system it can last almost forever. These panels are still chugging along happily. Keep up your good work.
would love to know what kind of solar panel used
Hello. Where are you? Im in Muizenberg. We too want to fit solar . Load shedding sucks .
@@melvynvanwyk3614 hello Melvyn. I only saw your question now. My apology. Well to answer you frankly, it depends on your budget. You can install a simple cheap system and still look at a starting price of R15K. Then you can go all the way and go completely off the grid that means anything from R150K and up. Let me know what your requirement is and I can put together a plan for you
I did this exact project for my parents in puerto Rico after hurricane for their tiny home to power 2 led lights, fan, small flat screen tv, small fridge w/timer, now the village on her road went solar after they saw what she had( what i put up) 8 houses so far all with small solar kit setups 200-500 watts...
Awesome..... Good job. Hope all is well.
That is amazing
Kudos for the Video! Sorry for butting in, I am interested in your initial thoughts. Have you thought about - Schallingora Computer Reconstruction Scheme (Sure I saw it on Google)? It is a smashing one of a kind product for saving money using this smart solar power trick minus the normal expense. Ive heard some pretty good things about it and my mate after many years got cool success with it.
😻
God bless you.
God bless Will for his SOLAR System design.
I'm as dumb as a mule when it comes to electrics but your video was precise and very helpful, I have the confidence to build my own set up now, thank you Will.
Just built my first system after watching this, my favorite video to date. So simple and elegant and future updates can be done easily. I think all in I'll be just short of $800 after I buy a battery. Using a lead acid deep cycle that is close to it's end for now.
Make sure in a long term install to use some grease on the connections to stop corrosion.
I'm looping around and watching you (Much younger!!) again to see if I missed anything before getting to the build. I wondered about 2 things. Grounding of the "non-mobile" systems and staying with DC power? I.e no need for big draws on watts so batteries don't take a big hit. Thanks for what you're doing in the future also!
I want you to come to my place and help me put my solar power in my van. I bought your book. You just make it look so easy.
Good info. Thank you for sharing. It really helps old souls like myself that can’t afford a sparky to do it for you. Cheers from Australia.
I love watching your videos, I hate electrics, but but you seem to explain things in a way that I understand, it's so helpful and I have learned so much from you, Thank you Will and keep up the good work 🙂🙂🙂 x
My first foot steps with this Video.. Thanks !
awesome stuff Will! I live in Santa Barbara and am trying to put together a small system as we have had several power outages since moving there 2 years ago.
Weve gotten by thus far with 3 Goal Zero's, 2 400's and 1 1400. It would be nice though t have a ore permanent residential setup. I gave up on Tesla after waiting over a year for a power wall and the they doubles the price. Love all your content.
In only one day, I have learned a lot from you. You make it simple for everyone to understand. Thanks for everything.
You are awesome Will ! Q: Could you have connected the negative charge controller wire to one of the negative screws on the fuse box instead of the negative terminal on the fuse box?
This is exactly what I have been thinking about and need for my van (yeah, I'm a not-by-choice vandweller). Having watch all of your solar-power videos (supported by my own understanding and experience in electronic/electrical assembly) I have total confidence in your knowledge and expertise. You are my one-stop source for solar video tutorials.
Hi! I just set my system up today! Awesome video! Quick question Which fuse should I put my Dometic 1200 vent fan in? Love your work! 👏🏾👌🏾🙏🏾
You have explained very clear. Thanks
I can't possibly be the first person to say this.. but his last name is an anagram for POWERS WTH !
Hi I'm in the UK, I'm ok with DC/AC power ect.....did 10 years on generators.
Bit new to solar power, so I'm just following the basic rules.
You mentioned near beginning of your video that you was connecting 2x 100w panels in series (=24v+) for a 12v system.
My question is can I do this with my epever mppt charge controller?
Thank you Marc
Hey buddy I’m just new to this stuff can you also say what you can work from the system etc kettle and a toaster and a fridge etc etc
Love this build!
What are the blue wires connected to ?
Great video! So can this system power things such as a bench grinder, or a mitre saw? If used for like 1 min or so? What is this system supposed to power on average? Thanks.
Velcro brand industrial velcro my friend. Awesome stuff. The adhesive is crazy strong, and the velcro is super strong.
And those BlueSea systems fuse panels are really nice. Used them in a recent project
Can you make a video with these components: 12v 400a battery bank, 5,000w inverter, charge controller unknown. system must be available all day.
how did u know all these? ur so smart!!
Why do you recommend running the solar panels in series, versus parallel?
I don't understand why you put the output of the controller into a 25 watt fuse on the panel. Isn't that backwards? Pretty sure it is. The electrical in/out puts go on the sides ground into the little side terminals and the the fusses branch off to a load. Now you'll only have 300 watts to power both the battery and the inverter ( or 600 if it is in series) before you blow a fuse.
Hi, thanks but not very minimalist setup. I am a student looking for a very cheap first time setup. So I can learn. Make mistakes, have cheap way to determine thins like losses from conversion and so on. Can you make such a video. Using multimeter for measurements, small solar panel. Cheap battery. I like your style. Seen videos using cheap stuff from freight harbor. Thanks
He "literally" lifted it with two hands! 😱🙃😁🤪🤣👍✌
What's the best way to start small and keep scaling up with batteries and panels? Just buy a huge overkill inverter and a few panels and a battery? I want to be able to do just 100 or 200 watts, and as I get the money throw on more panels and batteries, and eventually get it up to run my mining rig which takes 800w and runs 24/7.
Will - I can't begin to tell you how grateful I am for one specific bit in this. I constructed very nearly this exact system in my cargo conversion trailer. One thing that I dorked up was connecting the battery leads to the charge controller. I accidentally created a dead-short at the terminals. Because I'd put the output to the battery through the fuse block, I merely poped a fuse which saved me from cooking my brand-new MPPT charge controller. I might not have wired the thing this way if I hadn't seen your video and followed the best practices you set forth. I owe you one. Thank you for all you do.
8:07 I'm gonna copy it about 75%. So should I go with a 75 amp fuse?
Can I use this system in a shed? Also, can you hook up lights with a light switch to this system?
you can use it in a shed
yes you can hook lights up with a switch I think
What about wiring the charge that will be coming from your vehicle while your driving your RV? Is that easily done with any charge controller? Or do you need a more expensive charge controller?
Do uyou use 12 volt solar panels for 12 volt battery. Or do you use 18 volt panels (slight overvoltage) to charge 12 volt battery. For my country, in winter not too much sun. The 18 volt always gives something. I have no experience with 12 volt. What do you recommend.
When I win the lottery, I will ship you over to the UK to sort all my solar worries out ;)
Hi will I’m looking at setting up a simmilar size system can you tell me why you recommend 2x 100w solar panels over 1x 200w panel? Thanks
I'm trying to build a system like this purely for charging power tool batteries. But, I wanted to use the same system for separately charging the vehicle starter battery, rather. I have a 250W solar panel, a 30amp dual battery charge controller and a 200W Pure Sine Wave inverter. Is there any problem with this idea? Or anything I need to consider that I may not have, being a noob and all?
Thanks for this tutorial. I did my first solar experiment today with 2 "100W" flexible panels, a Victron MPPT controller, two 10AH LiFPo batteries and Iceco Go20 refrigerator/freezer. Nothing started a fire and I was making ice all afternoon. Didn't notice any wires heating up. Need a little bit more packaging, and confirmation that I can keep the freezer below freezing all night, and I should good to go for some car camping.
Hey Will, I have a remote vegetable garden on some shared land in the UK, so cold in the winter, and I plan to use lights, water pump, maybe charge laptop/drill batteries etc, and sometimes maybe need around 900 watts for other items. The other item I will power is a diesel heater for the shed which has a max draw of 9 amps for about 3 minutes as the diesel glow plug warms up, then while running its around 2 amps on max. I see your in your great video "The Minimalist" looks to be what I want to go for. As I am in the UK, it's very cold in the winter, which battery do you think would be best? AGM? Also, I still don't get how not to run the battery down too much, is there a setting on the inverter you can match to your battery, to save it draining below 50% etc? Do you have a video or explanation on this? Thank you !
LOVE your videos! What gauge wire would you recommend for 12 V accessories like LED lights?
led lights have extremely low draw in most cases so you can use wires that are quite small, 10 gauge will be more than enough, and depending on distance and exact draw, you can probably use 12-16 gauge as well. Anything else will be so small that it will be challenging to work with and won't support much draw at all.
Hi Will, For future california power blackouts, I recently got the ecoflow delta and two 100 watt solar panels. My house already has a professionally installed 20 panel grid tie solar edge system. With the new small solar panels for emergency battery power mostly in storage, would it be a good idea to get a small 500 watt grid tie inverter and use the backup panels at the same time as the solar edge? Is there a chance the new inverter could damage the other inverter, or make it less efficiently run?
I need a larger inverter in order to power my 1400 watt Vitamix. Any suggestions?
Thank you for sharing, you're a good person with a big heart. More patience to the seniors with solar panel installation.
God bless
Hello Will could you please show me a link to that fuse box you're using? this is not for sale in my country I need to but it outside. thanks!!
Could you run this with a Renogy DCC50S 12V 50A DC Board Battery Charger with MPPT?
You show and explain things really, really well. Thanks Will!
Hello, could you help me with a list of stuff I need to have solar powered lights for a green house and one or two fans ?
Why did you connect the fuse block to the battery outlet on the solar controller and not the load outlet?
why don't you use the DC load connectors on the MPPT controller?
I had the same question. Were you able to find an answer? To my understanding, you would be able to monitor the output current and voltage if you were using the load terminals of your Renogy MPPT controller instead of connecting the load directly to your battery. I think that the load terminals of the MPPT controller are limited to 20A so that could be the reason to connect the inverter directly to the battery.
Hello! I hooled up my inverter and no juice. I just bought harborfreight 7 watt solar panel, battery and controler. It says its charging the battery but the battery is not putting out power to tje inverter. What do you think is? Battery says its charged too. Yesterday i bought a new inverter and when i hooked it up it made a wierd crack noise and i think i toasted it, but why? Also i plugged in the negative first, which i saw u doing it in the video., should i hook up positive first nezt time?
Why would you suggest wirIng the panels in series vs parallel?
Great for Mppt controllers.
I have a small 7x14 cargo trailer camper that I have been wanting to install a solar system in. Right now it only has 12 volt lights and a 12 volt tv, but I plan on installing a Maxx Air ceiling fan and a 12 volt refrigerator. I had a 12 volt AGM battery that just died and am using my boats old lead acid trolling battery. The camper is wired for 120 volts with lights, a roof ac and mini refrigerator, but I want to start doing some dispersed camping. It also has a 1.25 amp Battery Tender charger/maintainer that will charge either AGM/flooded and lithium LiFeP04 batteries so in a pinch I can just charge the battery off of the generator. On your recommendation I just purchased Li Time 100 AH battery with low temp protection during Amazon's Prime Day sale for $309, and it is the start to my solar setup. I was thinking of going with a 200 watt solar panel setup to start, but I am very limited for storage space and many time I may have to, or prefer to park in the shade so I was wondering if there are any portable solar panels that you would suggest?
I have a 30a mppt controller and 2x100w panels. Should they be wired in series or parallel for maximum performance?
Series maintains voltage.
I have a Renogy 200 W. suitcase system that I use to charge two Battleborn lithium Batteries in my Rv. Recently it blew over onto rocks and one panel shattered. I bought what looked like an identical panel but when I hook it up just like the broken one it shows 18 volts and defaults. Won't charge. It is a 100 watt like the broken one. The built in junction box seems a little different. The charge controller is on the side that is good. Any ideas?
what kind of capability does 200 watt system give you? How long would it take to charge the batteries with good sunlight
Hi,
Thanks for the video.
I copied ypur system in my shed.I see two issues here though.
1.What if the 25amp fuse conected to the charge controler blows.Then the controler will lose connection to battery and still be conmected to the solar panel which is not safe.
2.Not conecting the load to load terminals on the charge controler will not give reading of what amps are drawn from the battery and will be no statistic as well.
How do we go around that?
Awesome video! I learned a lot. I have one question about the fuse box, though. I am a total beginner so I do not really know why do we need it, if I just wanna plug in my laptop and a couple lights to the inverter, do I need it? (If we aren't planning on running 12v devices)
I get that it is necessary to have a fuse right between the battery and its wire, but what is the purpose of this 1.25*20=25A fuse in the fuse box?. If it is necessary for safety reasons, why do I need the other fuses in the box if they are not being used? Can I simply use a 25A fuse between charge controller and the inverter/battery?
Can't we replace yeti goal zero 150 or jackery 140 or 240 instead of lead acid batteries???
what the van life community needed.
I have a question. I bought a camper van that has a converter in it so when the vehicle runs it charges the house battery. It I wanted to add a solar panel kit to the roof to also charge this battery when the vehicle is not running. Will it back charge and cause damage to the panels through the mppt charge controller when the vehicle is running?
Ok so I watched this video I've got probably about 5% nailed down 😂 out of the 5% I know is that a 400w inverter is only capable of running 200w total roughly after inefficiency.... how are you running a 750watt hot air gun from that inverter??? This I thought was impossible. I have a solar panel 200w kit that came with a charge controller. Ordered a 12v fuse kit as I will have a few 12v items ie lighting. I was looking at 1kw pure sine wave inverters and thinking spiralling costs. Will that inverter cover a run of sockets in a teardrop caravan. Literally just tv and phone chargers. Was thinking the refrigeration would be a 3 way fridge on gas and 12v to save draining the battery flat. Kind of glued the back boxes onto my wall panels and then realised I needed more to get it to work so any advise in regards to picking the right inverter would be great
how bout kits ready to go like a renogy one i was looking at a 200w started one any other companys ?
Does this system need to be grounded? If so, how?
Would like to know the same.
Thank you for putting this up. Perhaps a stupid question, Is there any reason one would need to use fuses instead of a breaker box? would substituting in, perhaps a marine breaker box with the correct size breakers be acceptable?
We need answers!!
@@goprobeto_1527 he definitely does not answer questions being asked…shame on him
@@flgirl250 I still think his videos are great in general and the content he does give out for free is extremely worthwhile.
i put a 12v 1.5w car battery maintainer panel up on the roof....now i can power my house.
@@ekoms108 yup i have to thank Will for it all, ty Will.
And what size batterys you trying to charge ...at 1.5w...thats like 0.125a per hour ..not even 1amp u would us more power that you collect ...just enough to start the inverter..as inverters draw power too
Would you change anything in this advice, 4 years later since you posted? Would be great to know.
I was reviewing this Mobile Solar project on your website and some of the links are wrong, The batteries are not there any more, and the Inverter is a modified Sine wave, not Pure. I know it is a major job to keep these links up and current, it a whole one day per week on my little channel and site. So thought you might want to know! Love your channel !
Hello solar family can someone tell me the bolton fuse for a 2000w inverter and the fuse box he used in this video please.
where doi get that fuse box, what is it called exactly?
Me: waiting for him to say the word: but
Seriously.. i heard that word 8 times in that video.
hi there, I have bought 4 solar panels 340w ,Max Current (Imp) 9.82A
Max Voltage (Vmp) 34.6V
Short Circuit Current (Isc) 10.51A
Open Circuit Voltage (Voc) 42.5V
Weight 18.7KG
Dimension 1664x992x35mm
Cell Technology Monocrystalline but I didn't parallel yet I need help before somethings goes wrong LOL, my system run by 48v do I need to do parallel them?
Our company need to find US Influencer for 12V 100Ah LiFePo4 batteries of local market,we want to know whether you can help us?Thanks a lot!
Hello, I know this video is over 1 year old, but really would like advice!
A 25W Fast charger for my phone.
For 5 hours a day = 125w per day.
With 3 D.O.A = 375W
4 hours of sun in UK
375 ÷ 4 = 93.75W
Rounded up to 200W
(I'm thinking this will mean I can afford to use my charger for longer if needed and still have 3 DOA)
On my list so far I have:
2 x 12V 100W Mono Solar Panels
1 x 20A 12v/24v Charge Controller
150W 12V - 240V inverter
35ah 12V Lithium Ion Battery
Will this be suitable for my needs of charging my 25W phone charger (as its my first time ever attempting solar maths after following a few of these videos), for 5 hours a day, with 3 DOA (but not 100% needed)
Hey...thanks for your videos. I pick your brain all the time for my new trailer conversion. So...I am planning an install of two 200W panels (Newpowa 200W Monocrystalline 200 Watt 12V Solar Panel High Efficiency Mono Module RV Marine Boat Off Grid (200W New)) on the roof of my new 6x10 trailer conversion. Each panel will have an inline fuse on the positive cable.
I also have a portable set of panels (Dokio 300W kit), which I normally use to charge my portable Jackery 1000. I will be joining the two rooftop sets of wires from the panels into one set using a y-connector and then entering my trailer roof. Then in the electrical compartment, install another y-connector which would allow me to , on occasion, connect my portable panels to add to the system solar input.
Sound like a workable plan?
The system I am building in the next few days:
Renogy 40A controller with Bluetooth, feeding a 100 Battleborn Lithium. The battery is also feeding the busses which feed a 12v fuse box, which feeds my trailer lighting, fridge, and stuff.
There is a catastrophic 300A circuit breaker and then a battery switch between the battery and the positive Buss.
The 12v fuse box is also fed by a converter (Progressive Dynamics PD9260CV Inteli-Power 9200 Series Converter/Charger with Charge Wizard - 60 Amp). That charger plugs into a shore power outlet, for the times I would be plugged into that shore power.
My shore power outlets are fed by a breaker box with two 20a SquareD breakers. That breaker box is fed by a plug in the outside trailer wall for the shore power connection.
The Buss also feeds a Renogy 2000W inverter.
Nothing installed yet. Am I good to go? What am I missing?
You are the most knowledgeable solar guy so I'm asking you. I have 180 watt Renergy solar panel on my van roof. I don't know how much my battery under under the passenger seat stores. Can I run a 200 watt 12v coffee pot on my 180 watt solar panel without blowing a fuse? All my appliances are 12v and under 180 watt. I only use one appliance at a time, other than my 12v iceco Go2020. Thank you.
Hello. I don't have much knowledge when it comes to this so l'm looking for help. I am building a small system for my home. Not for daily use just emergency use only. I have three 100w 12V solar panels and a 30A controller. What battery and inverter should I buy? The brand doesn't matter.
Any info would be appreciated. Thank you so much !
Need your expert opinion. These days people are commonly using a 12v DC setup where battery is charged by a MPPT charge controller while the load is put parallel to the battery (MPPT chargers here don't have a load/output option) via a PWM controller ( to avoid over discharge). In my view the charger will be over charging the battery as the load running is in parallel. Your view please.
I want to build a kit half the size of this . for my Mercury grand marquis. I can mount 1 100 watt panel directly to my trunk lid with screws and will be right where my battery and inverter are located in the trunk. I ordered 1 "Weize 12V 100AH Deep Cycle AGM SLA VRLA Battery" I already have a 2500 watt inverter and it's already wired from my car started battery to my trunk with 0 gauge wire and a 300-watt breaker located close to the positive of the starter battery. I ordered a " WirthCo 1213.1241 20092 Battery Doctor 125 Amp/150 Amp Battery Isolator" for my new battery. I just need to find a decent solar panel and controller. Do I need the fuse box? I did get another 150watt breaker for in between the doctor and positive of a new battery. Also how long could i expect to run a 200-watt heater that draws 2 amps
So I’m building a small cabin (144sq ft) and I wanted to do a similar version of this system, without the fuse box. Would I be possible to have: panels, cc, battery, and inverter, with one stand alone light switch wired off using regular romex? Sorry if that is confusing or doesn’t make sense? But for my application I do not find a use for the fuse box. Seems more logical just to fuse between component individually since I’m not running 12v appliances, rather using the plugs on my inverter to power “normal” things… would appreciate anyone’s input!
Nice setup good job :)
My main thing on the road is my Krups digital electric tea kettle. It uses 1500w. I've done some researching and hopefully it is correct. 3000w inverter, (2) 100AH deep cycle batteries, (2) 100w solar panels, and a 20a solar converter. Found everything for about $623. Am I correct in the calculations?
Have everything ready now to start getting solar panels ordered and finish the system. I dont need an inverter right now since I am running my ham shack on dc. Ive set the shack up with dc fans, lighting, and radio equipment. Ive installed a PWRgate mppt, PWRguard, and a Rigrunner fuse system. Using all powerpole connectors. Have my Interstate SLA batteries connected, my AC to DC power supply connected, but now its time for the solar panels so that I wont need the AC to DC power supply. The only other thing that I need is a DC Super Booster to bump the 12 volt up to a constant 13.8 volts that is ideal for radio equipment.
Fuckin' A you are smart......I need to do this for my Ram, want to be able to run a fridge, its a 50 quart fridge freezer dometic, will 200 watts be enough? Then just do what you did here and mount it to the vehicle....I am impressed.....wow!
The more you bend your wire. The more resistance you will have. Causing lost of energy and efficiency!
I don't understand how to get power to my DC fridge from this system.....help!! I have a cigarrette lighter adapter plug that came with the Dometic CFX3 fridge. I get all the other stuff, the inverter is for AC power..but what about DC?????? From what I understand it is better to run the fridge in DC, as it uses less power than in AC mode. The other thing is I bought the renagy 200 watt "premium" kit with the mppt, do you connect the Solar panels in series or parallel? And if you connect in series, doesnt that mean you have to use 24 volt for power? Or does the charge controller, same as you have here the 20 mppt, does it automatically figure out what voltage you want. I get confused on that part. Perhaps you could make a video on just that. Connecting in series vs parallel, and to 12 volt or 24 volt. Thanks!!!
I've been watching all kinds of your videos on this stuff. And others videos. My brain is boggled. Any chance I can tell you what I got and have you draw me out a blueprint of how I need to connect it? I have 2- 200 ah lithium ion batteries. 2 renogy 100 watt solar panels. A renogy 3000 watt inverter. I haven't yet gotten a fuse box. I have also a solar charge controller. All I need to power is a small fridge and a deep freezer and a water pump also a roof fan. Dude if you respond to this an help me I'd be glad to Paypal you some money for your time.
I have a good question for you. I’m travelling and i realy need your advice. I have a renogy 50A charge controller it’s maximum 25V open circuit voltage my solar panels are enerwatt with a 25.9V open circuit and my renogy charge controller shuts down everyday when the batterie are full charge. Then it takes hours before the charge controller goes back to working. Do i have to change my solar panels for something with a smaller open circuit voltage that is less than 25V could that be my problem?
Hi Will, great video. I was wonering if you could tell me where to put the dc to dc on board battery charger in with this configuration? Thanks again for all your insight.
Hey Will - love the videos - looking to set this up for an off the grid project - would you recommend a 12 V or 24 volt setup ?
I have a 40 amp solar charger instead of a 20 amp. Is this still fine?
So many specialized tools! A hammer crimper? Seriously? I like your videos to help me learn how to set up and connect my 200W system from scratch for my greenhouse ( for a fan and drip irrigation pump.) But Im going to be using lineman pliers and what I have, not buy specialized tools i might only need very infrequently.
Hi how are you ? Can you pls help me whit few things
I want to run one 300 watt solar panel to run on off grid ....but to by onest im little bit confused which this... (Because im new on this )
Which Power inventer, which battery ,and which solar charge controller i need to use to run 300 watt Solar panel of course im lucking for not to expensive product
I up you understand my inglish thank you....
Where do I find a fuse box like that, what size would I need for a 2000 watt pure sine wave inverter ? I already have two new 6 volt 445 amp hour lead acid batteries. Planning on building a system for my cabin. What size solar panels would I need.
Would it be safe to use something like a SB350 SB Series 350 Amp Anderson Powerpole Kit between a larger 1200 to 1500 watt inverter and beefier branch connector as well as another between battery and branch connector to give flexibility to not mount the larger inverter but connect it when you need to move your system around? Would like to understand how to add resistor into this circuit to reduce spark when connecting and disconnecting battery.
Small question: my fuse box looks almost identical to yours except it didnt come with a 25a fuse and my controller is 20a. Is it ok to just buy a 25a fuse and use it? Perhaps the box isn’t engineered for that much?
will why do we need that fuse box if my inverter comes with a radical fuse
Could you use 2 206Ah LiFePO4 Batteries instead of one with these components? Say I wanted to upgrade in the future, how many batteries could I jam onto this system?
First time viewer here. Thank you for all your time and effort. I'm a retired Army electrical engineer and this video was totally awesome, packed with valuable information and design ideas. The furthest I went with solar was for my motor home. 3 175 watt panels, 4 12v gell cells and a 5kw inverter. Came in real handy when out of gas for the 5kw generator and no mains to tap into. But now looking into putting some panels on my small shed for my mobile home. We get winter storm outages now and then. Thanks again for a great vid and loads of info!
