As mentioned in previous posts, what would be a "usable" inverter/ charge controller backup in case of a primary systems failure? I have a OutBack FlexPower FP1-2 for my primary, but in case of repair being needed, what would be a good , inexpensive charge controller/ inverter set up that would run the needed items during a 1-2 week down situation? Figuring on being able to get away with minimum needs, lights, refer, possibly freezer , radio...just curious as i am going to start looking for used, or low priced back ups...Thanks, rsbhunter
