I have a used Grid Tied 5 KW type solar inverter I want to use in a remote area on a solar array. I understand it shuts down when it doesn't see the grid voltage/60hz signal. Is there some way to activate the inverter with out the grid signal. I don't have an extra $1000 plus for a true off grid inverter. I've thought of a couple of ways but I was told the solar array/inverter would fry anything I connected to the inverter to simulate the grid signal. I'm not familiar enough with AC as related to grid interconnect loads and impedance to prevent this if true.
