Ran across a deal on a large Hoffman electrical box for $200 on Craigslist. I've been looking for something to house the two 48V 280Ah batteries I'm currently building for use in my house. I wanted something that was enclosed, could fit 16 cells long in a series string so it had to be around 49...

I've been researching 48V 16S LFP BMS for use in a golf cart in the distant future. I see in the past some used a JK in a 300A version. Still a good choice or is there something else out there? Looked in archives here, just curious if there are better choices out there.

I touched on the subject just now in another thread. https://diysolarforum.com/threads/why-is-squared-disconnect-so-much-bigger-than-plastic-pv-disconnect-switches.42860/post-628782 I haven't been on much, I finally did get my PV array up. It took talking to various contractors regarding the...

Went here to look up specs for the 6500EX and nothing is listed under off grid inverters. https://signaturesolar.com/shop-all/ Maybe they aren't selling these anymore or updating the website. Interesting development.

I ordered 2 Zoom 100Ah 12V LFP batteries for my fishing boat trolling motor. I've looked at various 120V AC to DC chargers, most are overpriced for the charging amps. I've been searching around for an inverter/charger instead, higher charging amps and added bonus is I can always run a 120V AC...

The balance leads are just too dang short for how I want to mount the BMS to pack. I see some have used a busbar but wonder about increased resistance from the connections leading to erroneous cell voltage readings. Lengthening the lead might be a better choice or purchasing a longer lead...

Interesting video on the problems associated with energy in Aussie. Plenty to discuss if one ignores the climate change discussion. One has to wonder if this is the trend that will happen in the States as big money attempts total control of energy while trying to maximize profit.

Ran across this video this morning and I know R290 has been mentioned a few times in the forums by our friends overseas in Europe. I do think ground source may just be on the way out using R290 monoblock air to water heat pumps with some thermal storage/buffer tanks. My eventual plan with the...

I've run into this about 3 times now. The Batrium will reset SOC to 100% when there are consecutive days without reaching full charge. An example is yesterday I see SA shows about 7Kwh of charge went into the battery. Battery was at 40% in the morning, so there is no way I could reach 100%. I do...
