I live in Baja, Mexico. The grid here is essentially an island, and we are at the end of the transmission line. So we have dirty power with wide swings in voltages, one phase dropping out, brownouts, and occasional frequency fluctuations. People complain of fried boards on refrigerators, stoves, washers, etc.
I have a sol-ark 15k, 6.5kw of panels, and 42kw of batteries, no sell back. I really only need the grid if we have 2-3 cloudy days in a row. But, because I am connected to the grid, my house voltage/frequency is synchronized to whatever the grid is putting out.
I want to protect the electronics and appliances in my home while at the same time still using the grid for charging batteries when needed. After an hour of searching, I cannot find any specific guidelines for safe grid voltages and frequencies that will protect 95% of home electronics.
I tried setting the sol-ark grid params to something like 220<>250V, and 57.2<>62hz. But with these params the grid cuts out dozens of times per day - and if the batteries are being topped off at 9000w, can't be good to be continually ramping up/down. Not to mention the annoying notifications. I loosened up the params quite a bit, and the disconnects have stopped. But I have no idea if my home electronics are at risk.
Does anyone have a good source for safe voltage/frequency ranges for home appliances and electronics?
