Intelligent Anti Feedback Solutions
In some applications, Power Grid Corp normally requires the PV system to be equipped with anti feedback function.That means that surplus generated electricity is not allowed to be injected into the grid via a low voltage distribution circuit and must be for local consumption. With intelligent anti feedback function, the system sends a control signal to the inverter and adjusts the power output of the grid inverter to attain the objective of providing max power to the local and no feedback to the grid .
