Something different, Mobil battery backup that also powers the vehicle

Well,

Have an idea to make a mobile battery backup system. We loose power 4-5 times a year and have a 10.6kw solar system that becomes completely useless when our power company shuts things off.

What I would like to do is load up a industrial cart with a 48v mega storage cart that when the power company pulls the plug I can plug this into the house and have power and possibly enable the existing solar array.

Even thinking of putting 4 300+ watts of solar on top of the roof, Have room for 4 panels.

Attached is a pic of the cart, there is a ton of room for batteries and it can carry 2000 lbs.




Open to all ideas or comments.

Thanks John

Forgot to mention,

48v motor, cart is in need of complete rebuild

Sounds like a great project I'll be following!

Cover that thing with solar panels and fill it with batteries. Sounds like a fun one. Side and rear panels could be on hinges to close up the body, but then pivot up to face the sun. Hard to tell without dimensions, but maybe fit twelve 60 cell sized panels?? There also look to be room for a generator if the sun is not enough.

I know a good source for some fuzzy dice....

The roof is real close to 4' x 8'+, so 4 full sized panel should work.

Im thinking around 5k in storage,

Thinking of a second inverter that would be mounted in the garage so when power goes out just drive up to inverter and plug it in after disconnecting from the grid.

Fuzzy Dice and Solar panels, Cool.

If you set it up for rows of LFP cells, you can just keep adding as budget allows. You can fit a ton inside that thing.

I was also figuring 4 panels down the roof would fit nicely. And then maybe 3 more on each side that you can lift up to face the sun. And maybe another pair like that on the back.

my 345w panels are 1mx2m 3'(ish)x6'(ish) So 4 of them together is 6x13'. I guess you could put 4 on the top if you want massive overhangs. but that just means you run into things because you forget that you have overhang.

I take it your large PV array is mirco inverter based? So you want like a 6wk 48v hybrid inverter to pretend its the grid on a transfer switch kind of setup?

most likely all manual switch over at first, expect the battery cart will spend most of it's time driving around the property. When the power goes out would drive it to the inverter that is mounted at the house. The array is 400' away from the main panel and ground mount. I thought my panels were about 3' x 4' but guess I better go measure them.

A new hybrid inverter would make things easier, was told it would be $10k for one that would work with what I have now. Although I have not really priced anything yet.
