BASICThe elgris BASIC controller measures the power from the grid or generator. In applications where the load is relative constant and equally dived over the three phases, a single phase measurement on the lowest phase is a good solution. The controller reduce the output of the solar system by adjusting the set point of the inverter. When the generator is not running, the feed in protection is triggered and becomes active. When the generator is running and powering the load, the controller prevents the generator from running in a non optimum point of load and thus from high fuel consumption and avoids serious damages due to the low load.
