an�-backflow mode. SUN limiter has two an�-backfolw modes, the minimum mode and the average
mode. In the minimum mode, SUN limiter will control the power of the inverter according to the
phase with the lowest power to ensure that no reverse current will occur in each phase. In average
mode, SUN limiter controls the output of the inverter according to the average of the total power
of the three-phase load, which may cause single backflow. The controller is produced in the
minimum mode to ensure no an�-backflow happens to the customers.
