Solar system, Trace 2412 , Inverter/Charger, Morning Star charge controller, disconnect switch, combiner box, 6 Kyocera=140 watt panels, 8 batteries. Older 12 volt system, works good, 6 volt batteries are 5 years old, very good system for off grid camp, ect. I used this in my home as a Uninterrupted power supply unit since 1998. I just updated to a bigger/higher voltage system. Email me for any questions.
