If the charger will not charge the batteries, it means the charger is bad or the fuse for the charger is broken

Our trace legend series 1 model L 1512 inverter/ charger overcharges our coach batteries in our 2000 Monaco Diplomat . Any suggestions?

Is the inverter configured for correct type of batteries? Did inverter come with temperature sensor what should be connected to battery to prevent overheating? Are batteries in good condition, acid level, clean posts etc?

Our Inverter works but the battery charger seems to trip out everytime we try to charge the batteries.

There is no way to guess what the problem is, we technicians use a multimeter to look at the electrical circuit values to determine the problem. The charging circuit could be bad, or the batteries could be shorted.

My fredom 25 inverter is not running the refrigerator in my motor coach when I turn the generator off or unplug from shore power.

Is the inverter rated for more power than the refrigerator draws (watts). Does the coach 12 volt power drop (at the inverter) below 12 volts when the refrigerator comes on? If so, you may need to increase the wire size from the battery to the inverter. Make sure that the voltage doesn't drop at the battery. If so, it may need replacement or a larger capacity battery. When the battery is being charged, measure the voltage at the terminals (which are hopefully clean)--it should be 13.5 to 14.5 volts.

Xantrex Freedom 458 Combi inverter/charger 2000 watt

OK my 2000 Discovery does the same thing. Try and hit the inverter charger with your fist 3-4 times, then listen and see if the charger fan starts up. I will be bringing my inverter to Portland this week to have the tech look at it. The other thing is it could be the transfer switch. Will let you know.
