3.7 Zero Export
Zero Export aims to make the total inverter power generation close to total power
consumption to avoid the over generated power flowing back to the city grid.
It can be done through the following steps.
Through RS-485 and Meter communications, RC reads the current total power
generation of inverter and the difference between power generation and
consumption. It also reads single generation by communicates with inverter.
Calculate inverter target total power generation via Zero Export algorithm, and
then assign the total generating capacity to the connected inverter to instantly
control a single inverter generation through RS-485.
When power consumption increases, power generation will also increase;
when power consumption is reduced, power generation will also be reduced.
