I've been lurking for a couple years here on and off, built my own solar generator two years ago with the knowledge gained and have used it several times to power my fridge. Now I think I'm ready to design a whole-house DIY system with battery backup. But I'm still learning how hard it is to...

I have a handful of Ryobi 18v batteries for various cordless power tools, and I saw this item on Tindie, which made me think I could power an inverter with these with the right circuitry. Anyone played around with this? I'm not enough of a sparky to figure it out myself.

Well, nothing is really ever finished. I still want to automate it with a Raspberry Pi, etc., but for now, it's in production.

I initially joined this forum because I was trying to learn about batties (Lead Acid, LiFePo4, etc.) I just stumbled on this technology. This video is a 50 minute presentation at Stanford that I find riveting. The company started to further this research is Ambri.com.

After trying various mobility options for the generator (mostly rolling tool boxes) I finally settled on a hand truck. Much easier to work on a flat board. I was inspired to do so by this video. What I've done with my design is to add in a shunt to allow measuring the current going to the...

I'm laying out the components of my portable solar generator. Currently I have a 200A fuse to go between battery and inverter. However, I'm considering buying a breaker instead, mostly so I have a convenient "off" switch. Also wondering how to figure out what size. I upgraded from a 2000w...

Not the usual warning about lead acid batteries...

After lurking for a while, I finally ordered the parts to my first DIY solar "generator". I learn best by doing, so I am trying to spend as little as possible while allowing for upgrades. So for now I have only ordered one panel. There are quite a few 100W monocrystalline Solar Panels, all...

Hi Everyone, I live in Northern California and have wanted to do solar "some day". The recent power outages have encouraged me to get on it. I am interested in first building a small portable "generator" in a rolling box. I stumbled on this forum trying to learn about batteries. I generally...
