Multiplus "Grid" will not stay on when being powered by generator when Air Conditioner is turn on and ramps of the "Watts".
1. Multiplus will charge batteries and run other loads (Microwave) when powered by Generator or shore power.
2. Multiplus will run Air Conditioner on Battery power or shore power. Air Conditioner has a "Soft Start".
3. Multiplus powers off after the load ramps up, when I turn on the Air Conditioner on powered by Generator power.
4. Generator runs fine and provides the Multiplus with 121 volts @ 60 Hz and what ever amps is required to charge the batteries. I have the Multi plus set to charge at 29 amps and the generator has no problem providing this. The Multiplus provides power to everything fine except the Air Conditioner.
5. If I have another load 1100 Watts (Tested with heat gun), the Air Conditioner starts and runs fine, no issues.
Any Ideas what needs to be changed.
