Thanks, I am not understanding, " dont worry about switching between circuits". Won't that be a problem when the grid power comes back on? Pat

I have a solar domestic hot water system that works great. One problem, In the event of a power outage my 115 volt gruntfos circurlating pump will not run, causing an overheating situation. The pump draws only .57 amp and 65 watts. Does anyone know of a affordable battery backup system that is an automatic switch over in the event of a outage. Thanks Pat
