About

Generally, a single-phase inverter can realize zero injection to the grid only with a single-phase meter. However, in some cases, users want to install a single-phase inverter in a three-phase system. But with a single-phase meter, the inverter can only realize one phase’s export control, which is not suitable for a three-phase system. SolaX single-phase inverters support connecting a Chint three-phase meter to realize three phases export control. Zero injection can work in such a case.

Connection

There are no special requirements for this connection. Just follow the installation instructions for each part, and the meter should be a Chint meter. The AC output of the inverter should be connected to any phase. A three-phase meter should be installed before the grid to give export control to the whole three-phase system. The connection of the three-phase meter is the same as in a normal three-phase system. Connect the signal cable to the “Meter/CT” port of the inverter.

Settings

Set export control to “0” if it’s required.
