5.5.2 Introduction to meter/CT Communication
X3-Hybrid G4 inverter should work with an electric meter or current
sensor (CT for short) to monitor household electricity usage. The electricity
meter or CT can transmit the relevant electricity data to the inverter or
platform, which is convenient for users to read at anytime.
Users can choose to use electric meters or CTs according to their needs.
Please note that the meter/CT brand required by SolaX must be used.
Note!
The meter or CT must be connected to the inverter, otherwise
the inverter will shut down and alarm SolaX "meter failure"alarm.
Smart meters must be authorized by SolaX, third party or
other companies, Unauthorized meter may be incompatible
with the inverter.
SolaX will not be responsible for the impact caused by the use
of other appliances.

If the user has other power generation
equipment (such as inverter) at home and
wants to monitor both, X3-Hybrid G4 inverter
provides Meter2 communication function to
monitor the power generation equipment.
For more information, please contact SolaX.
Note: If you want to connect the meter, please ground the GND terminal of the Meter1.
