What I’m worried about is frying $61.000 dollars worth of solar on my roof, so I’m going to wait till the contractor adds the software he said I needed,then I’ll charge on if needed, but because I got 2 enphase batteries they seem to be charging during the day, and dump about 30% during the night, now if it rains for more than 3 days, I’m back on the grid, I don’t know what happens after a snow yet?..I’m learning...You have to make some adjustments for certain things. Such as going to propane water heater is probably best as a small tankless water heater takes 1500 watts large ones take even more10kw to 25kw. They are very efficient because they don't constantly draw power but when they are running not efficient at all. Propane on the other hand for cooking stove and water heater are probably better options unless you have a massive solar array. Also if you get a large generator, 10kw or larger and do not put it on fuel conservation mode there should be no issue charging the batteries, if you look around most generators output sine wave power the problem is when you overload a small gen or have them throttling up and down trying to conserve fuel. if you are really worried about it buy a large inverter generator which is safe for all electronics.
