We have put together a 850 Wdc portable stand-alone PV system. It uses a Blue Sky 3024DiL charge controller, a pair of SunXtender 250 A-hr AGM batteries (24 volt configuration), and a Xantrex Prosine 1000 inverter.
We have been using this system for powering "events" and getting some good marketing from the activities. Everything has worked out well, and the system is not being used now and probably won't until March or April sometime. We have let the system fully charge the batteries through bulk/absorption and now float. The float conditions are 26.4 V and 2.0 A at a battery temperature of 21 deg-C. My first question: is it alright to let the batteries float every day for the next 6 to 8 weeks, or should I disconnect them from the rest of the system until we are ready to use the system again? My second question: since the 3024iL can perform an equalization, is there a safe equalization procedure for these AGM batteries? - Peter Peter T.
