I have a 1999 National Tradewinds with a Heart Freedom 20D inverter which doesn't charge the house batteries. It has power to it but does not seem to be powered up. I'm wondering if there is a fuse inside on the input side that might be blown. Ideas? Thanks Arnold


Thanks for all the help on my problem and found my inverter was kaput. Since parts are no longer available for one that old, I bought a new Xantrex and controller. Will have it installed by local tech. As you all know, a very expensive fix, but necessary.

Inverters don't charge batteries. They discharge them.

Converters charge batteries.

Actually, that model is an INVERTER/CHARGER, so it should charge the batteries when it receives a source of 120 VAC from shore power or generator.

Does the "pass through" feature work (do outlets powered by the inverter work when the inverter is turned off? This would confirm that 120 VAC is getting to the inverter/charger.

When the inverter is turned on, the light on the panel blinks. One you tube video I checked indicated it was in "Service watts" mode. I reset as per instructions and light still blinks. Sorry, I don't know what Pass through outlets you are referring to.

What you should do is put your meter on the output of the converter right on the screw terminals. Should show 13.6. If you then put the meter onto your battery terminals and it is less than that while you are connected to power, it's very likely that either the positive or the negative feed to the battery has a loose connection. I was plugged in for three days and my batteries went dead. I found the loose connection on the negative main wire feed to the batteries on the terminal strip at the converter. A quick check is to locate those two heavy wires, and wiggle them while someone looks at your lights. If they suddenly go bright, you have found the bad connection.

A "Pass through" is any 120 VAC outlet that can be powered by the inverter (i.e. you have 120 VAC even without shore power or generator).

Galley, microwave and TV are common choices.

The "Pass through" is when there is an external source of 120 VAC (shore power or generator) the inverter does not "invert" which takes power from the batteries, Instead, it just "passes through" that 120 VAC and also automatically start charging the batteries.

Reading your inverter/charger's owners manual will help.

You are correct, HIS doesn't charge the batteries. But, it's supposed to, THAT is the reason for his post. [emoticon]....Dennis

Not worried about semantics. Likely there is a reset button on the "device".
