PG&E's net metering is awful so I'd like to keep my power to myself. I have a small solar array and two PWs. This raises two questions:
1) I've set my controller to "self-powered", but it keeps feeding power back to the grid when the PWs are not full. This morning the PWs are at 79% and it's sending about 1/3 of the power to the grid. Is there some max charge rate of the PWs that is limiting the ability to charge them?
2) What is the power loss of all the conversions?
DC > AC by the solar inverter
AC > DC to charge the PWs
DC > AC to use the power in my house?
Thanks,
Russ
