No house battery charging…
“If it ain’t one thing…It’s something else”…. Rosanna Rossanna Dana
Help…
Situation:
When i plug in my shoreline, apparently the inverters (Trace) are not allowing the power to charge the house batteries.
On the Trace panel, the yellow “inverting” light is ON, but the AC#1 light indicating the presence of shore power coming into the inverter is OFF. There is some power coming into the house…we can turn on the cook top, the frig is fine, etc…all of which, apparently, doesn’t operate off the inverter.
When the generator is running, the AC#2 light is on indicating the gen-power is coming in… and is charging the batteries. Incidentally, the inverters are warm to the touch with the gen on. Makes me think the inverters are probably functional, just not allowing the charger function to work when on shore power. Not being blessed with much in the way of electrical knowledge (what the hay does this guy need a motorhome for???) Im beginning to think some kind of switch…changeover, etc, is not working.
I did find one problem when I got into the inverter enclosure. The small cooling fan is inop…I know I need to get that corrected asap.
Thanks for any help or thoughts….ty

Btom, 2nd driver storage bay, is the shore line switch ON / and lights ON?
Bedroom switch panel, do you have AUX fault? If yes just reset… -
What position are your inverter bypass switches in? Should be in normal position, but you can try to put them in shore power position if you are plugged in.

Dorel & Per….
I piddled with this situation all morning. The items you guys mentioned have been checked. The house power is clearly getting into the coach…otherwise the cooktop, frig, etc would not work….which they do! It is only the portion of the incoming power that is allocated for recharging the house batteries…all six of ’em!
I talked to Jeff. He’s gonna cogitate about it, but his initial thinking is we have a switch bad…just a matter of locating which one. I’m thankful the inverter/chargers are working, because when the gen is on, all is well…batteries charge, etc.
I was already going to Jeff’s Sunday for a date with some tires and a few other things.
We’ll just add this thing to the list…ty

BTom,
What you are describing is paradoxical because once you get 120V power to the panel which it soundsl like you have regardless of source, it should reach the inverters and allow them to do their charging.
I can understand why Jeff has to “ponder”. (Tennesseeans do not cogitate, they ponder)
Please post the outcome.

Jon…
I’m not sure which panel exactly you are referring to … but the Trace panel that normally would have green light AC#1 lit when on shore power…that light isn’t on, in spite of the fact I’m plugged in. On gen the AC#2 light is lit as normal. The monitor panel indicates both legs having power on them regardless of gen or shore. That makes me think power is coming into the coach (from the shore line)…getting past the monitor panel…(it shows power on both legs)…then getting stymied before it gets to the charger function… I don’t think it’s the charger function itself that’s bad because, remember, it charges properly on the gen.
I’m glad I was going to be at Jeff’s anyway. It is going to cool down here in Pigeon Forge…we might even open some windows…that would be different, wouldn’t it?

Transfer switch? I’m assuming the Trace’s have been set correctly, show On when pushing the red button one time and the chargers are also on with at least 15 charge amps.

YEP!!!
I’m with you on that…I’m in total agreement….not to mention I’m thankful for the thought that my two inverters are probably good.
Tom…I gonna have Jeff put on a Pressure Pro on my MH and car with new rear tires…I’m assuming he gets that TPMS from you. Looking forward to having that sucker on my bus!
Sure appreciate everyone’s thought on my electrical issue…PC is a great place to be a part of!!! ty

Could the AC1 light just be inop? Have you verified that the batteries aren’t getting charge voltage?
-
If the AC#1 light is out….they must both be out! It is showing no presence of shoreline voltage on either inverter. In fact, the monitor panel shows power on both legs when plugged in to 50A with the shoreline.
I think we’re gonna limp along until we get to Jeff’s next Monday….ty

Have checked the AC voltage lines going into the inverter with a multimeter to see if voltage is getting to the inverter?
