    You haven't told us the voltage. That makes a difference. 2 awg with 90 degree C insulation is good for 190A if single conductors in...

    8 x 12V x 200 Ah = 19 kWh of battery, same size I have. Not sure what charge rate they like, but if 0.2C like mine, will take 3800W. You...

    The two are allowed to be longer than the four. They just have to be matched to each other. They could be matched to the four, but that...

    Sunny Island will give that. Plunk it down with a battery, and you've got AC 24 hours a day. It will start generator when needed, but...

    Hedges replied to the thread The "Meg" Build.
    Your individual panel measurements x 6 came close to 215V, so the string measurement of 205V was either less light or hotter. Individual...

    I doubt the plastic of a fuse holder would break down at 80V vs. 48V. Difference is likely covers to keep fingers off the conductors...

    Having a cougar sounds like a privilege. Hopefully you can learn to just give each other respectful distance. They're supposed to be...

    In the morning, SunPower is 100V out of 121Vmp. SanTan is 90V out of 150Vtypical. 83% vs. 60% is a big difference. Any shade on SanTan...

    Gotta wonder why. There could be some differences in light absorbed at off-angle, but wouldn't expect 5x difference. What...

    First get the specs and types of motor loads. Those are the hardest to start. Brush-type motors should be easier, and induction motors...
