AGM status when gone for long periods
Small system in off grid cabin in Baja Mexico. Two 190 watt panels, thru Xantrex C60 controller to four 12v Deko 105AH AGM batteries. Xantrex 1500 watt modified sinewave inverter/charger to power center. The batteries will be new and a BTS will be used. The cabin is shut down for 4 to 6 months at a time; what would be the best way to leave the system when gone?
