Xantrex Inverter/Charger-- Set for AGM's goes back to GEL

[ronaldbrinley]

Charger was acting up. So I changed to new AGM batteries. Now the Charger will not let me change the battery type to AGM goes back to Gel1, seems to be working in this mode. Will it harm new batteries charging in this mode?

Ronald,

Welcome to the FMCA Forum.

In a word, YES, it will harm the AGM's.

Your inverter/charger should have three programmable choices for battery technology: wet cell, AGM and gel. AGM and wet cell are VERY similar and while AGM is the preferred setting, wet cell will be very close. Gels are different and is really the only setting that could harm your batteries.

I can not get the inverter to go to the wet cell charging mode. Seems to be stuck in the gel 1 mode. At a loss as to what to do. I guess I will try to call Xantrex on Monday and see what they say. Will turn off charger until then.

Try to reset it by disconnecting the 12 VDC from it and turning off the 120 VAC breaker to it.

Brett can this be done by just disconnecting the shore power and disconnecting the batteries at the posts?

Herman,

Really depends on how the inverter is wired to batteries, but if direct, yes. Note, a reset is not a "cure-all". But free and may work.
