Solar System, Trace 2412, Inverter/Charger, Morning Star charge controller, disconnect switch, combiner box, 6 Kyocera=140 watt panels. Older 12 volt system, works good, 8= 6 volt batteries need replacing, you can use them as core returns , 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.
