Try putting a load on the generator (like a 1500 watt hair dryer) before the Heart kicks on then once it transfers to the loads and starts charging, shut it off.
It might be finding the voltage or frequency to high for its liking. Plug it directly into the generator of somewhere before the inverter to get gen power.

I would look to borrow for a scope or at least use a cheaper meter that can accurately report the frequency. Try slowing the generator to 59 Hz to see if the inverter likes it better.

When the generator is started, the Heart inverter kicks on and starts to charge, after about 3 seconds it kicks off, then on, then off and repeats. The voltage and frequency of the generator output look good. 120V L-N and 60-62 Hz no load. The Heart just doesn't seem to like it after it kicks on the charger. (Sorry, no scopemeter available) What is very interesting is that on the other pole of a transfer switch connected to the AC input, is a fairly inexpensive gas generator, pull start, on wheels etc. This puts out 108VAC at 59-60Hz. When connected to this generator the Heart immediately latches in and will continue charging flawlessly at 100ADC. For whatever reason, the Heart, doesn't like the voltage waveform of the Onan generator. The Fluke 87 multimeter that I was using to test, was catching some type of transient (frequency reading would shoot up to 70-100Hz) when the Heart would latch into the Onan. Other that that with my simple tools I could see no real difference between these generators, other that the 108VAC of the gas generator. Any ideas, or known compatibility issues with this equipment?
