I participated in a thread that is titled SolarFlex (or something like that). The bottom line is that I bought a new trailer in the fall that was the dealer thought was solar ready with the new SolarFlex But it really was zamp ready OTG packaged without the core components. I've worked a deal with the dealer to get all the components and due to a problem scheduling and the need for solar to power the 12Vdc fridge (not propane) I went to work installing most of the components myself. Still have an inverter and one more panel but before our spring trip. Here is one of my responses. In there, there is a wiring diagram for an inverter but it shows the basic components needed and positioning in the system. NOTE, as mentioned before the battery-to-inverter wiring is vastly different gauges depending on the power or the unit.
Cheers
