On grid w/battery [RE-wrenches]

[Joel Davidson]

Bill,
If I go with a non-battery inverter, I'd keep my SW4048 and use it for a non-PV
UPS. The SW harvests 2700 kWh/year, but I wouldn't mind another 135 kWh/year
plus approx. 80 kWh/year that the SW consumes floating the battery at night. I
think a non-battery inverter would harvest approx. 3000 kWh/year from a 2200 WDC
STC array at a 12 degree tilt in Los Angeles. Does anyone still use the old
UT-SW4048PV non-battery model? If yes, what size array and how many kWh?
