It appears one charger isn't charging. Our Liberty has two 2500 watt Freedom inverter/chargers. I don't know how they share the charging loads. We've been dry camping a lot lately and I noticed charger #1 would indicate an overheat, would reset, and then start charging again. Charger #2 doesn't seem to be doing anything. The dc amp load on charger #1 would be up at 130 and #2 would be at 0-10 amps.
3 or 4 months ago I changed the dip switch settings to the Liberty default which is all off. That setting disables "power sharing" and, I guess, lets the charger charge at full rate. The chargers are rated at 130 amps. To solve this until it gets fixed, I changed the power sharing setting to 20 amps on charger #1 and it is working, I guess, ok and is charging the batteries without overheating, though slowly. The dc load on #1 is around 70 amps and the batteries are slowly increasing voltage over many hours, something like 11 volts to 14 volts in 6 hours. Doesn't sound quite right to me. The charger breaker on #2 isn't tripped.
We're close to Liberty in Chicago and I am thinking they might be best to figure this out.
Or, would this maybe just for sure be a bad charging board? Maybe it needs further diagnosis?
Perhaps a call to Gusdorf might be in order before visiting Liberty?
What do you think? I know some here have repaired their inverters or had similar situations.
Does any of this sound familiar?
A basic question: how do the two chargers share the charging load? Do they talk to each other? If they are set to allow full current through, 130 amps, does each only deliver 65 amps? Surely they wouldn't deliver 130 amps each! I've never seen it so I don't think that happens.
Need some more school.
