7. ZERO EXPORT FUNCTION VIA SUN LIMITER
The inverter has external zero export function. This function is optional. It can collect counter-current power to control
the output power of the inverter, so that the power of inverter and load can be o set, and the excess power will not be
fed back to the grid. If you purchase the inverter with zero export function, an external zero export device ( SUN limiter
or energy meter) will be included in the package which is necessary for the function.The SUN limiter shows as Pic 7.1.
You can see corresponding line mark next to the green interface. The green terminals on the left are the interface
of three-phase AC line (L1, L2, L3) and N Line (N), and the the right are the interface between three sets of current sensor
and one set of control terminals. SUN limiter will collect voltage and current from these interfaces and send control
signals to the inverter.
