Solar power

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.
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...
 
Have any of you calculated or measured your power and energy requirements in units of watts and watt-hours?

If I don't power the 240 volt devices, a 3000 watt inverter is more than adequate.

BUT, it doesn't take very many loads running throughout the day to use quite a bit of energy. A very scaled down use can easily use 6000 to 9000 watt-hours in a single day.

Just look at what your full size refrigerator needs in watt-hours for a typical day.

I had ordered a Bluetti AC300 solar gen back in October. Yesterday I was supposed to take delivery of the unit. However, only the battery was delivered with no inverter. That B300 battery is a heavy sucker. Its shipping weight, in a cardboard box, was over 100 lbs. I suppose I will get the inverter soon.
 
Energy prices look to be headed sky high.
A solar gen is starting to look very attractive as a means of offsetting those high costs.
The system may not help you survive, but it may help your wallet survive.
 
Charging up my rock pals this morning . 250 watts
