[RE-wrenches] What inverter? (was Faulty PM-60 circuit board)

[Joel Davidson]

Hello Ray,

He has had almost no utility power outages since he got his PV system in 
2001. By going batteryless, his dc-to-ac conversion efficiency and kWh 
production should increase by over 15%. He has not decided if he wants to 
keep the SW4048 and float charge his batteries with the grid for emergency 
power.
