Keystone 27' TT Honda Paired EU2000i Gens Help

If it's real hot outside AND you have a pair of hondas paralleled AND on eco throttle, even with a startup cap, yes, when it tries to start, the pair may not always recover from eco throttle to full throttle fast enough. then the AC draws enough current (locked rotor condition) to overload the genny's long enough to kick them out.

If it is doing this with eco throttle OFF, then something else is going on.

For example, is the fridge on AC? the WH on AC?
