Trace's SW (Step Wave Series)definitely causes probs with the variable
speed blowers in Trane products. A 50 microfarad cap across the inverter AC
out seemed to cure that ill, but overall the gas fired Air conditioner
still pulled almost 2500 watts for a 3 ton unit and had to run all day to
even begin to cool down the vacation home. Definitely a generator load. I
try to stay away from PV powering  any standard forced air systems. Anybody
 ever try those PV direct swamp coolers?
