5.3 Sits Setting

"Site setting" is equipped with three modules, which are "export limit control", "power control" and "meter
reversion". The "export limit control" and the "power control" are mutually exclusive so that only one can be enabled.

5.3.1 Export Limit Control

The purpose of the "export limit control" is to limit the power supplied to the grid. The inverter generates electricity
to the grid when the power source is positive, and takes electricity away from the grid when the power source is
negative. For example: The exported power is set to 0kW, the power generated by inverter is 5kW, the power load
consumed is 4kW, the inverter generates 1kW(5kW-4kW = 1kW), then DataHub will limit the power generated by
inverter to 4kW.
The control methods are divided into "average phase control" and "minimum phase control". If the "export power"
were limited to 0kW, there will be no influence on a single-phase inverter, the inverter will not supply power to the
grid. As for a three-phase inverter, the "average phase control" is to average the power of the three phases generated
by the inverter. For example: the three-phase loads are 3kW, 4kW and 5kW respectively, a total of 12kW. Under the
"average phase control", the power generated by the three-phase inverter is 4kW, 4kW, and 4kW respectively, a total
of 12kW, as well.
Under the "minimum phase control", the power generated by the three-phase inverter is 3kW, which is the minimum
power of the three-phase loads.
*Note: Before using the "export limit control" function, make sure that a meter has been added to the DataHub. The
output of device will be abnormal when connecting to three phase three wire under "minimum phase control" mode.
