Yamaha 2000iS and softstart with AC?
I have a older Yamaha 2000iS (not sv2) and a Magnum 3012 hybrid inverter but can’t run an AC due to the poor surge capability of the generator (it drops voltage too fast for inverter to ‘support’ it s...

“Not fast enough to keep Yamaha2000iS from bogging down and sending the system into oscillation causing 400+A draw from batteries (and not doing the AC any good)… “
Neither my former two GC’s nor my 200a/h LFP is capable of anything close to providing a 400a draw, yet either would run my 11kbtu air cond via inverter by themselves…Though I can’t now recall an exact figure, I’m certain that upon a Locked rotor condition, that the chemically sluggish GC’s voltage sagged considerably for a brief period of time…My sense is that it is in this way that lowering the cut-out voltage (strictly per mfg’s embedded limitation) would be an acceptable practice…
I should also add to my previous that my ProSine 2.0 inverter runs the 11kbtu air just fine, but my goal is to have the Honda 2200i to operate consistently while in the eco mode…
