My suggestion would be to list: 1. Daily kwh use budget 2. Details (amps, voltage) of any loads needing large current (eg water pumping) 3. Approximate location 4. Expected use (full-time, seasonal, …

It's not quite as simple as it will/won't work with mppt. An mppt cc needs some overhead pv voltage to buck down to charging voltage. I've seen suggested minimums of 20-30%. The actual overhead will …

In strings of 2 assuming array output of ~2000w, that would be something like 2000 ÷ ~70vmp = 28ish amps per array into each CC. That gets bucked to ~80a into a 24v bank. The array vmp will vary a bi…

AFAIK lithium batteries should never be charged in freezing temps, and should be current restricted discharging. Depending on ambient and inverter loading, I suspect it would be hard to get enough he…

I've used scrap bits of composite decking as shims. It's UV stable, doesn't corrode or rot, and is pretty easy to work with common woodworking tools.
