Sure. Think of all the PC manufacturers that buy components made by other companies, stick them together into a single unit, and then sell it. Also, you can list the components (just as someone can say "this PC has an Intel or AMD processor"), but you can't claim that you're DALY or say you're...

Yeah, that would be doable. I may try some different configurations. The old controller didn't like the lower voltage, but the new one may not have a problem with it. Thanks!

Correct. It's a 24V system. Since the charging voltage needs to be higher than the battery voltage in order to actually push power into them, the 1100W / 40A math makes sense (that equals 27.5V, whereas 1200W / 40A = 30V).

Thanks for the feedback. There's really no easy way to re-distribute the panels at this point (check my first link in the OP). There are obstacles to both the east and west (my house to the east and a forest to the west). It'd be way easier to just get a different controller. I guess I'll...

4-series, 3-parallel for about 80v@15a (it was originally 2-series, 6-parallel since my pv combiner box had 6 inputs, but my old charge controller wanted a minimum of 36v to charge the batteries, but whatever algorithm it used would drop it below that for higher amperage, so I combined them to...

Hey all, A couple of weeks ago I finally finished setting up and turning on my system with 12x 100w panels. ( thread here: https://diysolarforum.com/threads/finally-turned-on.22094/ ) It wasn't charging up my batteries as well as I expected, which I figured was probably due to the generic...

Update after 1 week... I've been troubleshooting issues with getting the batteries charged up. The ATS switches correctly. By default, it'll switch to house power at 22V and back to batteries at 27V. On the evening of the second day, the batteries only charged up to 26.8V, and wouldn't go...

My work computer (with 3 monitors), home server, gaming computer, a couple of 3-d printers, regular printer, network components, plus whatever gadgets I'm tinkering with at the time. Best guess is a constant minimum load of 200-300W. Over the course of a day that's 4800-7200Wh. According to my...

lol. Originally I had the BMS located higher, but the darn leads were too short to reach the battery. If I had realized that sooner I would've mounted the back board lower. The cells were the last components I placed because I didn't want to drop anything on them. :) Unfortunately my house...

It's been almost 2 years since I ordered the first two panels and set up a small proof of concept with a single 12v AGM battery. Another ten panels, 7.3kWh LiFePO4 battery bank, 24v inverter, and a transfer switch later, it's finally powering my home office. (Note that this system is not...
