For the technically minded here’s a copy of the wiring diagram for our system.
This is a simplified diagram of my system which was installed by Hugh Piggot of scoraigwindelectric, Bill steel of Generator services and myself. The charge controller is the standard proven unit with a special defeat relay added by Hugh to prevent the dumps operating in the event of the generator starting. The DC dumps are normally turned off and priority is given to the AC ones through the inverter (you need a quality inverter to do this as they can be running for days here) I dump through 3 oil heaters 2 in the porch and 1 in the bedroom, however this is quite ineffecient as you have no control over it and there are many days when the house is too hot. I do have a 4 stage 2kw immersion heater element which I intend to fit when we overhaul the plumbing. This will enable us to heat a thermal store with the excess power so we have more control over when we get the heat out. A solar thermal array on the roof will also heat this store as will our wood burner but all this is on the to do list along with the solar PV and mini hydro turbine.
