I have a 2000 Discovery with a Heart Interface 2000 inverter. I have never used the inverter. When I recently tried to use it, there is no power. I have 12v power to the unit and out to the converter next to it. Any suggestions?

Obvious things that you probably already checked but there are breakers on the inverter itself and if you have the 'remote monitoring panel', I believe it overrides the power switch on the inverter itself (i.e. if the inverter says ON but the panel says OFF, it will be OFF).

Are you sure you are using outlets and/or appliances that are wired to the inverter...not all are.

Your description has me puzzled. The Heart 2000 is an inverter/charger. It would be very unusual to have an inverter/charger and a converter. When an inverter/charger is installed the converter is normally removed and the charger portion of the Heart does the charging.
To find out which outlets should be powered from the inverter - There should be a 30 amp breaker in the main breaker panel labeled 'inverter'. Open that breaker while plugged into shore power and check outlets for power. The ones with no power are powered from the inverter.
Now close the inverter 30 amp breaker and disconnect from shore power and turn the inverter on. Make sure the inverter light is lit on the inverter box. The outlets that did not have power should now be powered.
What do you use to charge the batteries?

did u try reseting it.

I do not have a remote panel (at least that I can find) There is a converter next to the inverter. Inverters are new to me. I have never used one. I do not have a breaker in the main panel that is labeled "inverter". I have about five or six breakers and they are labeled Air Cond #1, Air Cond #2, Appliances, Coach Power, etc. The breakers on the inverter are for AC power out. I got the inverter to turn on by pressing the buttons on the inverter itself ("inverter" & "charge") but I can't get any AC power inside the coach on anything.

is it possible that the power from the inverter has to go through the ground-fault interupter outlet inside the coach? I'm going to change that out today and see if it helps solve the problem.

If there is a GFI on a circuit with receptacles the AC has to go through the GFI.
If the coach power breaker is 30 amp that is the AC breaker to the inverter.

Ramzfan · 03-14-2012, 01:02 PM

I changed out the GFI receptical. The old one kept tripping. Now, when I connect the coach to AC power, the invertor will stay in invert mode. When I disconnect the AC power, inverter immediately goes to "overheat" mode and the fans come on. Something is wrong but I don't know how to find it. I need help!

This morning I tried something new...I shut off the entire coach AC breaker panel and then tried the inverter again. No luck. It immediately switched to overtemp/overload mode again and the fans started running. I tried the same thing by just switching off the 20A & 15A breakers on the front of the inverter...still no luck. I'm beginning to believe that the problem lies in the inverter itself. I guess the only thing left to try is to remove the 120V load wires from the inverter and see if that still creates the problem. Any suggestions...?

If you look to the left of the breaker panel you should see the Genset 1, Genset 2, Shore and Inverter wires. All should be marked. Check those connections. I have seen burnt wires in that location before

Thanks Heater. Doesn't it make sense though, that if I've shut off the outgoing breakers on the inverter itself and it still goes into an "overtemp/overload" mode, that the problem is in the inverter itself...?

Yes unless there is a short between the inverter outgoing side and the breaker.
