Well I switched to residential. Much nicer and easier to use and the temps are controlled. I can run it off my current inverter and batteries though I did have room and added a fourth battery. E issue is the sodium chromate that they use to protect the piping in the cooling units. The EPA has mandated that they use less and that is why so many newer units are failing sooner. Without it the ammonia would eat thru the cooper pipes faster. It is now a system designed to fail. The old days it would fail from a plug of the sodium chromate plugging the line. Now it is not enough of ot causing the walls to weaken and break on the cooling units. The change over is the best thing I have done.
