Hybrid PV/Battery/Generator [RE-wrenches]

Ray,
Yep. Allan has it right. I believe it's because transformers work 
with the P to P rather than the RMS voltage. If the genny P to P 
under load is low you run out of headroom to push amps into the 
battery as the battery voltage rises. That's also why HF 
switcher-type chargers are far less sensitive to low P to P.
