    Where a DC power system has energy inputs both from AC mains supply (or AC generator) and solar or wind, then the SC300 must share the load power between these sources. Generally, the preference is for the load to be supplied from the alternative energy source first, and take energy from AC only when there is not enough solar or wind energy.
