Off-grid solar package to power AC loads and incorporate back-up diesel generator - ideal for remote homes.

Read more

An optional PV solar system can be incorporated to generate sufficient energy over spring/summer/autumn months with only occasional diesel use. The generator will be required more in winter - depending upon sunlight and load requirements. 

Normally, loads are run from the inverter which is kept charged by the PV solar array. If the batteries become low or loads required are above a level which the inverter can sustain, then the inverter will signal the generator to start, once it is up to speed loads are transferred to the Genset and the inverter then operates as a battery charger to replenish the batteries. There is no break in supply during changeover.

The system can be programmed so that the generator will run at certain times of the day, or that it will not run unless battery is very flat.
