Looking for an affordable and simple solution for off grid back up power to your solar array? Check this out. This is how I did it for less than $800. Anyone with a little bit of a fixit ability can do this. You no longer have to worry about monitoring your system on extended cloudy days and plugging in the back up generator to recharge your battery back up. Just plug and play once you get it set up. #offgrid #backupgenerator #diybackupgenerator
