Hi,
I have an Onan 5500w connected to a MP2- which has power assist, my goal was to utilize the battery storage to reduce the fuel consumption of my generator. So I set up the ESS assistant, which works great when connected to shore power. As soon as I turn on the generator I am able to draw about 14 A from the generator once I exceed that it drops off the generator power and begins to invert fully and overload. I've tried everything I can think of, I tested the frequency of the generator checked the voltage etc. etc. If I delete the assistant the generator will load fully and work perfectly with power assist, the problem is as soon as the loads satisfy the charger begins to charge the batteries utilizing the generator which defeats the purpose of energy-saving/fuel saving at the generator.
Anyone have issues with the ESS assistant taking power from the generator? It doesn't like the feed from the generator, after a certain amperage. I've adjusted all the voltages and make sure that the generator was not dipping below the parameters for incoming power. I just don't understand why it works up to 14 or so amps soon as I have a second load it immediately drops the generator feed.
