Setting your Trace Auto Gen Start Parameters

This is one of the parameters that often gets changed. For instance, if your shore power connection only supports 30A you'll need to adjust this parameter downward to avoid tripping the shore power circuit breakers. If you forget to reset it to 47A when connected to a 50A hookup then the inverter will only draw 30A. If you have all 4 air conditioners running you'll draw more than 30A and the inverters will provide the excess from battery power. This will run down your batteries to the point where the generator starts due to the Low Battery Cutoff Setting, which are set in menu 12, "Generator Auto Start Setup". So, short answer: check your "Set Grid Amps AC" setting in menu 11. Clear as mud right! LOL!

Hi Dave, I am curious why "Set Grid Amps AC" is set to 47A and not 50A when you have 50A coming in?

Also, I went to charge up the batteries yesterday since the coach is stored with no electric. When I left it last Sunday the inverters were both in float and the batteries were at 26.6. When I arrived yesterday, the batteries were are 24.9 even though everything was shut down. It took 3 hours of generator time for both inverters to be in float and batteries read 26.8. I guess this is due to menu 10 "Set Absorption time" is set to 3:00? Since I am not using the coach and only top off the batteries would it hurt to reduce the absorption time to 2:00 hrs? I remember reading somewhere that absorption time is important.

Thanks,
