batteries overcharging

I am getting a fault message on my inverter remote panel and the batteries are overcharging and boiling all the water away. Is this an inverter failure? There is a Xantrex Freedom Marine 2 (about 4 year old) installed in the RV.

Welcome to the forum! I had the same problem with my Dimensions inverter and their factory told me I needed to limit the AC current which the charger could draw down from the 25 amp factory setting to 5 amps! The consensus seems to be that my inverter is of a bad design.

Hopefully someone with your model will come along with a solution for you.

BTW, you might want to include the details of your rig in your signature line. It will help others help you.

Good luck...

It certainly sounds as though the charger portion of the inverter has run amok. What is the fault indication? Are the Leds on the inverter showing overload or overtemp? Or low battery? Do you have a remote display that can provide additional info?

Is the temperature sensor attached to the batteries so the charger can adjust charging to temperature? That can make a modest difference in charge rate.

Also, your inverter can be set for different battery types, e.g. wet cell, AGM or Gel. Make sure the battery type is set to Wet Cell (the type you apparently have, since you say it boils water away). This is covered in the owner manual.

I am wondering how the inverter is determining that.. If it is by measuring battery temp then there are 3 possible causes.

1: Charger failure, since I believe your charger is part of your inverter, this means inverter failure

2: If it only happens when main engine running: Alternator regulator failure.

3: Shorted cell (This is only if it's measuring temps) in battery,

When a cell shorts your 12 volt battery becomes a 10 volt, and what is proper charge for a 12 volt is over charge for 10..
