Important to check your charge rates

Hello
I just discovered my 3 year old 8d lifelines are damaged do to over charging. My float voltage on rs3000 xantrex factory set at 13.7or higher. Lifeline recommends 13.1 .Its important to check your voltage and confirm from the battery manufacture that the voltage is acceptable .This may be why some folks get a few years and others get 10+. Xantrex default settings are wrong and without the correct panel cant be corrected as far as I know. Magnums appear to be adjustable with the controls.I didt look at voltage and it cost me 6 8ds.The previous owner replaced the factory set after 3 1/2years so the voltage problem likely came from the factory. Please confirm your settings.

Have that same inverter in the Magna we just bought. And, as far as I know, I don't have the controller to check/reset the charging rates. I do know it came with 8D AGMs and the rate is supposed to be set for them, but I don't have any way to verify that easily.

hi mr_d
I think you have a silverleaf on the dash and a total coach by the bathroom. To check on the front push info button until you see the inverter page. It will tell you what's going on or push inv on total coach screen. Keep us posted regarding repairs on the rig.

You should have a phone-type connection from the inverter to the temperature sensor on the batteries. Unplug the sensor and watch the charge voltage. The default battery temperature on my Xantrex RS2000 is 103*F. This past winter the float voltage was 14.4 when below freezing outside. I posted here and got the above advice. It worked, float immediately went from 14.4 to 13.3.

If all else fails, take a DVM and check the battery voltage when plugged into shore power.

I do and it doesn't allow me to change the charge rate for different batteries, just turn the inverter on and off. In fact I found that neither panel will start or stop the gen set, I have to manually start it from the gen itself. I thought it worked when doing the PDI but then Premier wired in a hot line to the back and it hasn't worked since.
Yep, waiting for more info from Cummins NW as to the status.

I'll add to this warning: don't assume the shop that installs new lifeline batteries knows to change the charge setting on the xantrex. I had to tell them how to do it and that it had to be done.

Adding to the above...

Anytime you have anyone provide a new battery you MUST insist they provide a copy of the data sheet indicating the operating voltages and have them circle the ones that apply to your installation.

Have them staple their buisness card or copy of bill of sale to it.

Your responsibility is to insure your system meets the needs of the battery...either pay them to adjust or DIY but get it done.

I will try the temp sensor. That would be great if it works. This whole charger thing has been nuts. Whats funny about this is silverleaf missed adding the ability to change charge rates and have just now discovered the error with the subject never being brought up over 8 years. This means nobody with silverleaf has tried to set there voltage with a xantrex inverter. The feature will be added but will require sending in the controls for an update. With so many going with magnum it may not be needed in the future.

I did disconnect the temp sensor and the voltage dropped to 12.9v on float. I will check with lifeline Monday . I have 6 8ds on there way and lifeline wants this charging issue resolved before I put them into service. Silverleaf is also working on the problem. Removing the temp device may be the temporary work around.
