Living off the grid for this remote house comprises of 14 x 245 Watt REC mono-crystalline solar panels, Xantrex 60 Amp solar charger MPPT (Maximum Power Point Tracker), Latronics 3500 Watt continuous (off grid solar) inverter, Woods 60 Amp battery charger and 12 x 4RP1330 Amp-hour Exide Enerstore deep-cycle batteries.
This Off Grid Solar system provides 14.78 kW/hrs per day on average which is adequate for a modern house with efficient appliances including washing machine, fridge, television, entertainment, lighting, kitchen appliances, water pumping and workshop.
The control panel includes 7 x solar disconnect circuit breakers, which act as a device to measure 2 panels at a time for warranty and servicing. It also includes a change-over switch from the inverter to generator, meaning that this off grid system is in a switched configuration so that when the generator is running all electrical loads are supplied from the generator, hence saving on fuel costs.
It was a solution of getting reliable electricity to a site where the cost of mains connection was quoted at $32,626.
