It works!.... Battery back up

Thanks to Chris (DVC500) I got the fever to build a pure sine wave battery back up. I got a 300 watt pure sine wave inverter off eBay for about $80, bought a few parts and dove in. Just 5 min ago I tested it. The magic white smoke is contained! Wooohooooo! I did not make it so it automatic charges the batteries, but I'm using wheel chair gel batteries and they keep their charge for months if not used. I can charge them manually if needed and this way I'm not running a charger all the time.

Thanks Chris!

PS I ended up buying a few relays. If someone needs one, PM me. They have "solder" bases. They're a pain to wire, but at least if a relay dies it's just unplug and plug in a new one.

Good Stuff, Freddy, congrats! You must've wired the relay up correctly too!
Now the sheep will be happy, and warm all winter
Nice box you mounted it in. All safe and secure.

Nice job, but far too neat and safe. Here is my

Nice job Freddy!

tsb,
The wood in the base plate is fire proof wood right?

That looks good to me Tom! It's what I "wood" have done before I got my sheet metal tools. If it works...it works!

It was such a fun build I kinda want to make one with a cheap inverter to have emergency lights for the house.

I do metal fabrication for a living. I try not to bring my work home.
Anybody can buy a Hoffman box and fancy quick strip, but a piece of
scrap wood and some drywall screws. Priceless.

Those gel batteries are great! I've installed some in a few motorcycles I've worked on, & have one in my RD350. You can abuse the hell out of them (not charge them ... ever!) & they still come back for more! I have one in a lawnmower that I haven't charged in 18 months .... I can go out there now, toss it on a charger & it'll be good to go for another few years!
