Battery Problem

I have an off grid system here in Jamaica. Yesterday my system went south, the Charge Controller says that the Batteries are at 26.9-27.2 and says that they are floating but put a load on it and the inverter Faults and shuts down. I have (6) 200 watt Evergreen Panels, Outback CC, Outback2524 inverter and 8 215ah wired into 2 strings for 24 volt. Average use is 4.4 which I admit was more than I had expected so soon. Biggest thing is (6) batteries are @6.35 one is @7.64 and one is at 8.06. how can a 6 volt battery have more than 6.3 volts. I am able to run things off the panels but does anyone have any ideas

Re: Battery Problem

Charles,  that inverter has a connection for a temperature sensor input, with available readout using a MATE, unforturately sold separately. Since you are in a warm climate it is possible that it is shutting down due to temperature. I would suggest getting a temperature reading and compare that to the hi/lo limits for the inverter. Hopefully those values can be found in the manual somewehere.

You could try hooking up the batteries and panels for twelve volts and switch the CC if possible and run some twelve volt DC loads directly off that to see if all other components are working correctly.
