Battery Charging Problem

Grey Mountain wrote:
Came home after a short trip, plugged unit into 50amp shore power. Batteries are not charging. Circuit breaker on the Freedom 528 Inverter continues to pop. Did not have this problem when plugged into shore power on my last trip.
Also, doesn't appear that my batteries are being charged on my generator, or from the engine.
Suggestions?
Taking the unit in next week to have the fixit guy look at it, but would appreciate any insight here.
Thanks.

Two different things now.

1. With no shore power, your alternator charging has no effect. So the DC fuse/DC CB between alternator relay and the battery bank is blown or popped.

How about between battery and DC fuse panel? Lights, fans, etc work with no shore power?

2. With shore power you get no charging from the inverter charger to battery and the inverter CB pops. So the shore power pedestal is likely guilty, because the RV side worked till you got home and plugged in.

Taking the RV to the shop won't fix the pedestal at home, if that is what is popping the inverter breaker.

The generator won't do any good either says in the OP, but it is alternative to the inverter via transfer switch. How would the gen supply 120v to the inverter/charger's charger if the inverter has its CB popped? I don't know how all that works, but could be something there?

If on gen does anything 120v in the RV work or does it all have to go through the inverter first? Sorry no clue about how all that is supposed to work in a big MH, just maybe triggering some thoughts from others who do have a clue.

13.1 v?????Your batteries are charging !!!

Above 12.2. Each battery showing 13.1
No other problems.

What reading is "normal" for the individual batteries?

Is the voltage above 12.2 volts?

No other odd battery service etc. as you brought it home?

I long ago made a complete wiring diagram for the batteries. Each is color coded and numbered.
I disconnect each batter and measured using a hand-held voltometer. Each battery is showing 13.1 or 13.2.
Cannot disconnect and wait a week. Taking it in to the RV fixit guy next week. May just turn the problem over to them and let the experts handle it. When it comes to mechanical and electrical things, I'm a very good wood worker.

Charge batteries as full as possible

Take photos of which wire goes where. Take several photos. Tag cables masking tape

Disconnect batteries. Do not leave them connected in parallel!

Let sit for one week disconnected.

Use a hand multimeter

What is the voltage? Each battery

REPORT BACK PLEASE

Pushbutton 25amp breaker. Push to reset. I have checked all the batteries, appear to be ok. I topped off the cells just before our last trip. Had no problem with charging until I got back home. What reading is "normal" for the individual batteries?

Circuit breaker on the Freedom 528 Inverter continues to pop.

This is a pushbutton breaker on the AC side of the inverter? Push to reset? 10 amps or 15 amps?

Circuit breaker is normally for the 120 volt AC output not the 12 volt DC system. 12 volt DC is the large incoming fuse.

Manual

First check the battery voltage and water level in each cell. Post what you find.

If you have a portable charger you can put that direct on the battery and see how that works.

Post the results.
