How many watts is your generator mark? Can you pump water too? How horse is the water pump? Im asking because the electric company wants to cut power here during a fire storm. Of course thats when I need my water flowing the most.
When we moved here with the co-op electricity company, we would constantly get blinks and sometimes outages lasting hours. That's when I investigated the whole system, but never installed one. Problems were fixed 100% when they converted to a sub station up the road and changed out poles/equipment in the area. 125V, clean power now. Neighbor has one though and likes it. Tieing into the main box is the only way to go.
I have 2 Grundfos constant water supply pumps, 2 wells. 1 HP, ass kickers and the smart technology in the CU301 is to die for. Recommend for you the 15 SQE-07-180. Buy the system cheap off ebay. Install the console yourself, have a well service install the pump. Cheap, easy, and excellent value. Essentially what it is, is a computer/pressure transducer telling the pump how fast to spin based on demand from few RPM's (brushing your teeth) to 12,000. T off to an inline 2 gal. bladder tank if your system is closed, which I assume it is, unless you're part of a subdivision. I'm out here a lone so our system is "closed".
Good luck!
