AIMS PWRIC300012W 3000 Watt Modified Sine Wave Power Inverter with Battery Charger, 12 Vdc
I've had this unit for 18 months the smart charger is dead never did seem to work correctly was running on a bank of two group 29 marine batteries. this unit seems to have a high demand standby draw from the batteries which causes you to go into charge mode very frequently without even being used for backup power.
