Larry has a 1500 watt inverter with 4x260 watt on the panels.
I have a Xantrex 2000 watt pure sine wave inverter feeding two chest freezers, one of which I converted to a refrigerator. On occasion, if the compressor is in the 'wrong' position at startup, it will draw enough current to trip the inverter. I'm feeding the inverter directly from six golf cart batteries with 1/0 wire so there is minimal voltage drop. I'm curious to see if Larry will see the same occasional drops in the future. The rig is in the garage so I can't hear the shutdown alarm.
I went with pure sine wave not for the freezers, of course, but to feed more delicate stuff when the power grid goes down.
Those 4 kwh's would cost about $0.75 here in Ga in the summer but $0.40 in the winter.
Did you use a MPPT control as I did?
