  • Page 21 7 Zero export func�on via SUN limiter The inverter has external zero export func�on. This func�on is op�onal. It can collect counter- current power to control the output power of the inverter, so that the power of inverter and load can be offset, and the excess power will not be fed back to the grid. If you purchase the inverter with zero export func�on, an external zero export device ( SUN limiter or energy meter) will be included in the package which is necessary for the func�on.
