a Year Later, and still running strong.. and have used it a couple of times a weak.. Very Happy with this little tough guy.
very surprised that it puts out 200 watts more than advertised.. "Wow".. Highly Recomend.

I installed one of these to allow powering an emergency panel. I moved all the essential loads (AC, well pump, septic, refrigerators, lights) to a separate panel. The transfer switch allows me to power the emergency panel from a 12 kW generator without possibility of back-feeding to the grid. There are two relays that are mechanically interlocked. If one relay is energized, the other one is prevented from switching. My first one has been in continuous service for two years. I bought a second one to have as a spare.

Easy use and once by follow instructions started right up and tested usage for my trailer rv.

This thing didn’t stop over charging. I tried lowering the settings but it didn’t make a difference. Even when it said batteries were fully charged the volts would keep creeping up. Got up to 15.7v before I unplugged it. Unfortunately I installed it after the return window closed or I would have sent it back.
