Edit: The battery switch I used in this video is only rated for 48 Volts. So for 24 Volt batteries like in my case that's fine. If you are using it to disconnect solar panels however, the solar panels also cannot have more than 48 Volts!! A better choice to disconnect a solar panel from your solar system is if you use a DC breaker that disconnects both positive and negative wires. Get one that is rated 250Volts. Amperage depends on the size solar panels. But watch out with those DC breakers. If you wire them with the wrong polarity they will start burning. So always consult an electrician if you have doubts that you use the right components.

very useful video. no cuts. no editing. no bullshit. and she is really doing it. not showing only the results. congrats.

[matthewmccartney]

I am doing a similar project to keep all of my freezers running during a power outage. You are a clever girl.

[saberconstruction]

Your system looks much more professional compared to the one I just watched Mr. Prowse construct. Good Job!

[MrHanzeeman]

This lady did an impressive job!
Hats off! Her professionalism puts many other YouTubers to SHAME.
VERY WELL DONE!

Outstanding job Lilly, you did a better job than some electricians I use to know, I'm a disabled maintenance electrician in USA and I think you did a great job, you really did your homework, would like to know how well it works, but looks like it will do fine.

I love how you laid it out on a board, showing an easy schematic to follow, thanks!

[chronobot]

You were initially correct.

You did not need the thicker wire going from the inverter to the charge controller breaker.

There will only be 40 amps, not 100 amps flowing through it.

Being connected effectively to the battery doesn't mean all of the current is flowing through every wire connected to the battery.

Hey Lilly! Just wanted to pop in and tell you how much I've loved your videos. I rarely comment on videos but got to tell you that you're such an amazing, very intelligent, strong, inspirational, and talented woman who I admire! Sending you MUCH LOVE FROM TEXAS! ❤️ And God Bless you

Last week I learned a good lesson in Florida during Hurricane Ian. Always keep your solar charge system and battery at lest 4 feet off the floor. Also, make sure your solar charge system board has a shield that protects the electronic components from roof leaks.

You did a great job there, Lily.
I would just like to add something that I didn't notice you touch on in the video. It has to do with the hardware, the nuts, bolts, and washers.
#1 Regular steel hardware Has carbon in it. Carbon makes a high quality resistor. Never, ever use regular steel hardware. Be sure to always use stainless steel or brass hardware only.
#2 Never put washers between wire or component terminals, eg., between two wires or a cable and a fuseholder.
#3 Every connection has a volt drop or a little resistance. Reduce the number of connections to a minimum. Soldering wires to terminals reduces volt drop also.
I have seen components melted that came from the factory with improperly placed hardware. It did not take very long either. Attention to detail is very important, especially with high currents..
Beware of schysters that are copper plating aluminum for cheap cables and terminals.

Huge amounts of off-grid solar power go to waste once batteries are charged. Water heating also stores that energy and can be direct DC. Lilly needs to design a diversion system, manual or automatic. I love her work in all fields.

Super job. I’ve built several similar basic systems. From the size of your board, I assume you will mount it vertically. You may want to check the inverter and charge controller manuals to see if vertical orientation is ok. The thrust bearings in the cooling fans in both devices are generally not designed for vertical orientation. Keep up the great work. Love your channel.

[ebony]

Wow Lilly, your work is so precise and AMAZING! What a great example you set!

[WayneTheSeine]

Beautiful job Lilly. I just finished Will Prowse's book too. Awesome book. I have pulled together items for a 400W 12V 4.8K portable system for hurricane preparedness, to supplement my generators. If you can't get gas because no one has power you have to have a backup plan. Take this with a grain of salt as I am by no means that knowledgeable but the wire you ran from the controller to the inverter was probably fine as the controller is only using whatever amps it is rated for....no more. Also, tying the controller in above the fuse will had the controllers current to the overall current flowing toward the inverter and through the fuse. Maybe place it on the other end. I am sure folks will chime in and say I am FOS. I am glad I watched your video because you have a nice and neat layout to copy.

I worked at Best Buy as a MECP first class intaller and I am so impressed with your skills and attention to detail.

[gordonmitchell]

This is my project for late spring 2023, so I am all over your video's, they are superb!

[pioneer]

As a tradesman from Australia who specialises in commercial kitchen fitouts and in-house manufacture, I'm humbled by your skills, your smarter than me, your tools are better than mine, I'm a long term sub of yours, and I own one of your first APO 1, s Thankyou

[jannetteguillermety]

Hi, Lilly. I'm from Puerto Rico Island. Thanks for your videos. God bless you!

[davidstorm]

Is there a Part 2 Lily? Thank you for sharing your knowledge and ALL the videos you have made over the years. Amazing woman you are. Cheers
