2.4 Site Setting

Site Setting is equipped with three modules, which are Anti-counterflow Setting, Power Control and Meter Reversion.

2.4.1 Anti-counterflow Setting

The purpose of the anti-counterflow setting is to limit the power supply to the grid.
Generating electricity to the grid, and the power is positive; taking electricity from the grid, and the power is negative.

For example,

The anti-counterflow power is set to 0kw, the inverter generates 5KW, the load uses 4KW, and the inverter generates more power 5kw – 4kw = 1kw, datahub will limit the inverter to generate 4kw;

The anti-counterflow power is set to 2kw, the inverter generates 5kw, the load uses 4kw, the inverter generates more 5kw – 4kw = 1kw<2kw, this 1kw supplies power to the grid, if the inverter generates 7kw, the load uses 3kw, and the reverse The inverter generates 4kw more, the anti-counterflow power is set to 2kw, 4kw-2kw=2kw, the datahub should limit the photovoltaic power generation to 7kw-2kw=5kw,

The control methods are divided into average phase control and minimum phase control. When the anti-counterflow power is 0, there is no difference between the two for  single-phase inverters, it strictly does not supply power to the grid. As for a three-phase inverter: the average phase control is the sum of the three phases supplying power to the grid and taking power from the grid and canceling each other out. For example: the three-phase loads are 3kw, 4kw, 5kw and a total of 12kw. Under the average phase control mode, the power generation of the three-phase inverter is 4kw, 4kw, and 4kw, a total of 12kw. Under the minimum phase control, the generation power of the three-phase inverter is 3kw.

2.4.2 Power Control

Power Control includes: Dry Contact Control and DRM Control Disable.

2.4.2.1 Dry Contract Control

The dry contact control is to control the active power and reactive power of the inverter according to the high and low input state of the DI port. There are a total of 16 situations for user to set the active and reactive power according to each situation.

Display D1, D2, D3, D4 situations of DI port, green means the external input is high, white means the external input is low, a total of 16 situations;

Select the situation to be set;

Select active power control or reactive power control;
When active power control is selected, input the active power to be set, select reactive
power control, and input the reactive power factor and reactive power mode to be
