I never could verify the difference between being on shore power and generator power so here is what I did;
Even though I told the owner to purchase a battery charger and charge the batteries, I had to make another trip back over there and do it myself. He purchased a Schumacher charger and couldn't figure out how to turn it on. I verified the charger worked but hooked mine up and told him to get his money back. He doesn't need a charger that is smarter than the operator. :B
After two days on my charger I went back to do some diagnostics. I reset the inverter/charger and all seemed to be working okay. It worked in bypass, it charged the battery, and it inverted when shore power was cut. The only problem observed is that it tripped with a load of 1,600 watts which is below the rating.
I also got suckered into installing a replacement water heater due to the original not being winterized last fall and rupturing. During the water heater replacement the inverter was in bypass mode for a couple hours and the built in transfer switch overheated throwing a code.
I advised the owner we should replace the inverter and after consultation with a tech at donrowe.com decided on the Xantrex XC2000.
I will also be installing a subpanel for the two circuits like should have been to start with. The inverter feed is 30a and can bypass the full 30a into the outgoing 12 gauge wires. Unlikely it would happen but it could. A subpanel with two 20a breakers will solve that.
I will probably take the old inverter and see if I can either fix it or turn it into a 55a battery charger. The owner needs a reliable automatic system that doesn't require fiddling.
BTW, the NaturePower is the exact same inverter donrowe.com sells as the KISAE.
