The MMS1012 in my system will only output 8 AMPS when charging. Would original show 30A. I've checked and rechecked all the settings but still can't get but 8 Amps. Any information would be extremely helpful.

    Welcome to the forum Billnax,

    I don't have anything specific to answer... I would suggest starting with the basics. Use a good quality DMM and measure voltages at the inverter (DC battery bus terminals), AC input/output terminals, under load, and idling.

    It is not unusual to find loose or dirty connections.

    Are you sure that the charge cycle is not in Absorb or Float ?
