Can I send you a copy of Solar Independent Utility Systems Manual
Canadian Prepper has his copy
International building code book is a worthwhile investment and standards used worldwide
Brasil. Uma dica pesquisa sobre bateria lifepo4 de lítio são muito melhores e dura até 10 anos muito melhor doque bateria de chumbo que só dura 2 anos média
Hi Lilly, I've watched quite a few of your older videos when you were testing out archery equipment. I am wondering if you could recommend any archery dealers , preferably in Europe. Thanks.

@@SurvivalLilly love to send ya a free copy of my book Solar independent Utility systems manual
Just reply
I learnt more from your video than any other 'professional UA-camr' excellent presentation luv your work. 🇦🇺
Very impressive work lilly 👏👍😊
Cars been 12volts for long time nothing wrong with car fuse block .. big shut of switch and breaker b4 the fuse block.. can be done super cheap and be safe in (usa)
I feel like it would be much safer to go with the closest size down from the max, than the closest size up. If your controller can only take 30 amps(36 max), but the breaker doesnt blow till it hits 40, the controller would already be fried. Seems like youre better finding the closest size down from 36, like a 32 or something like that, or your equipment blows before the fuse maxes out. Right?
the solar charge controller briefl can put out more that 30 A. It also has internal protection so prevent damage at the inside. The inverter also can deliver more than 1000 Watts if you look in the manual. So for just a few seconds it is fine until the breaker breaks.
@@SurvivalLilly ok, yeah I was looking at it in the wrong direction.
Well they look different from what I'm used to working with I'm definitely interested in reading the material on this item
Could you cover your battery bank with a piece of 1/8" (3-4mm) of clear plexiglass or other plastic? You have plenty of ventilation.
Don't have solar. But thanks Lilly. Yeah probably watch it. Thanks
why so small solar panels? 375W?
I getting a bigger one soon
Really you are extremely smart. You know that I’m sure you do, GOD I wish you were near me. I’d have you hook me up one of the solar systems.
👍👍👍👍
Stay away from off brand breakers. That yellow breaker is junk. Go with Cooper Bussman.
Speaking of Will, I'm pretty sure would recommend going 24 or likely 48v system. Cheaper to build due to reduced cable and lug size. 12v is fine for an RV, but I would go with at least 36v system for virtually anything else. 48v is better. It could present some dangers to the careless and uniformed types, but that's not you.
I have found that 24 Volts parts like inverters have become immensely expensive. In a crisis it would also be hard to find one. For me availability is more important than saving a couple of bucks on thinner wires.
@@SurvivalLilly True. I forget you're in Europe and that many things are more expensive and harder to get. But the breaker, I wouldn't skimp on. I've had two of those and both failed to properly break at the rated amperage. Over time, one would not even reset. Went with Buss brand breakers and never had a problem. It's been 10 years. My main 100amp resettable breaker is also the master disconnect for the system.
Good job on the build otherwise 👍
Thanks for the tip I will look into Buss breakers 👍
Lilly, I know I am off topic but what is your inner circle think of the Presidential Debate and the potential for WW3 under a Biden Administration? Looking to see what Austrian citizens are thinking
Why is there a happy face on the MC 150, when it's 12.7 volts? What are you powering from your shed? Get to the choppa!!!
As the son of an Electrician and handy in electrical stuff myself and was almost an Electrician too, that system looks pretty good. Especially for an amateur. 👌🏻🙏🏼
As a nephew of an electrician's son i concur
😂 as an ex cook I think you are right 😂😂😂
My brother who I've seen 4 times in the last 20 years is also an electrician, so I agree!
@@tambob82 awesome 👌🏻
👍💯👍💯👍💯👍💯👍!!!! Great job, Lilly. This is going to be very useful in a down grid soon.
Austria needs a right wing Trumpian Chancellor to make Austria great again
Thanks Lilly! 🙂
I appreciate you explaining the different fuse sizes you used. a lot of solar videos on UA-cam do not do this and it was frustrating sizing mine.
I really like your videos, and the good advices you share. 🇬🇧
i like it/a very good job/thanks much
1st rule: Dont build high current electric systems on plywood.
How do think houses are built?
Better is using metal or nonburning plastic cabinets.DC current produce much sparks when short circut occure. Just advice!
Cement board or anything that is non-combustible metal cabinet etc etc…
Looks good
Survival Sparky.😃👍
Lilly!!
Loved your N&A episode. You and Sam were the BEST. I loved how you supported each other and gelled together to make it out💪
Us Americans could learn some lessons from you two!!
Love & respect from Philadelphia USA 🤘
It's really a nice system, well thought and made!
What size of fuse do you use for the supply on the shunt and the battery computer? I have the same and use a 5amp for both...
Thanks again for your effort with these videos!
👍👍👍
Another great video !.
I've learned quite a lot about solar
power and electricity from your videos ..
Great stuff !.
Hello Lilly!! Very informative Thank You !!
thanks for the video, I like your setup there. where did you get the chart that shows the wire gauges/fuse sizes? looks useful!
For safety reasons I would size the wire and connectors for twice what you expect in current; things can get loose and get hot.
❤
Hi Lilly, thank you for this video. Would it be possible if you could put together a diagram, parts list, and the conversion charts you are using?
The job off the baker is to protect the wires. Of course it need to be sufficient with the load.
In the charts we find the max current at serten temperature ,the cable can handle. The size of the brakes can be solve by the brakes carteristic.if it is type c the rool of thumb is 0.9 times max wire current.because it won't trip at his nominal current .so he need to be less .
Your nailing it and most importantly your not being censored like my book Solar independent Utility systems manual
So way to go !
Yes fusing fusing
I really like the voltage drop ap it absolutely lets you adjust your voltage drop by acceptable levels .
Love to do a shared video sometime
So next thing people get wrong besides wire sizing or breakers
The Solar array
Using a Solar path finder shows shading year around from anywhere in the world
You get the chart for your area and use the Solar pathfinder tool
Hi Lilly, excellent video. My only suggestion would be to write an orderly Shut down and Start Up procedure for your unit. Reason being if a failure occurs it would give you or someone else a starting point. Even though its small compared to the UPS and units I have worked on. The reason if there are loads connected and turned on when the battery breaker is switched on, the surge could blow fuses or trip other breakers. Thanks for the detailed lesson on sizing breakers.
After I build the door I will write an instructions manual onto it 👍
Looks like Will's setup. Nice.
Very nice setup, Lilly! One more accessory you can add for protection is a solar panel relay. Many solar charge controllers can be damaged if the solar panels are connected while the battery is not. So, if the fuses on the battery happen to blow, the charge controller can be at risk. To my charge controller, on the wires coming from the battery terminals, I ran a couple wires to a relay. When there is battery power supplied to the controller, the relay will be on, with a negligible draw from the battery. The dc positive cable from the solar input then runs through the contacts of the relay. Then if the battery fuse blows, the solar is automatically disconnected, in theory, before damage to the charge controller occurs.
Absolutely true. But I think my Epever MPPT can handle the current if the batteries are cut off. 👍
Any more plans in the future to show progress on the solar setup on your van? We are looking to buy a new one to camp/ travel in. Thanks, great review.
I sold the Van. Needed the money 😂
👍👍👍
😁👍🏼
A CAUTION: Inverters should be mounted horizontally NOT vertically. The internal fans are designed to have horizontal shafts so that the fan's bearings will last longer. If they are vertical the downward thrust of gravity will wear the lower bearing and may fail causing the inverter (or anything with cooling fans) to overheat and may start a fire. Check the instructions or the manufacturer.
That is correct. But I didnt have the space to mount it horizontally. I will only use the inverter with smaller loads tough, so it doesn't get too hot.
@@SurvivalLilly Sounds good. I have had 2 inverters and 2 charge controllers literally go up in smoke. Fortunately I was close each time. A smoke detector nearby would be good also.
bellissimo video
THKS
This is awesome. Keep studying. Youll find that doing this, youll always be learning and upgrading your system. Well done Lil.
Its so nice, should get a clear plastic door :)
Hello girl 😂
👍😐👍🇳🇱
Personal opinion, I prefer your political and survival videos over the "solar system series". As someone who doesn't own one it is very uninteresting.
Then go away
Don't watch it then!
@@TheRogey1 What a predictable NPC-like response. Did I say I watched the video? I have to click on the video to post a comment, genius.
@@rubygray7749 Another NPC who tries to shut down even the most innocuous forms of criticism with the stereotypical "Go away/don't watch" response, hoping to get validation from other fanboys.
Why should I leave if I like Lily's survival videos and news? Oh, because I'm not interested in solar systems, how dare I! 😱Grow up. The "you either like 100% of the content or shut up" mentality is childish, this is not a cult.

It's not all about you. If you don't appreciate one particular topic, then move on to what you do enjoy. Silently.
No need to be so intolerant and unpleasant about a very well presented subject which is not only interesting, but essential viewing to so many others.
When is the Austrian Freedom Party's election and should they win?
