Note!
Currently only PIN6 (DRM0) and PIN1 (DRM1/5) are functional, other
PIN functions are under development.
Note!
The meter or CT must be connected to the inverter, otherwise
the inverter will shut down and alarm "meter failure"alarm.
Smart meters must be authorized by our company, third party
or other companies, Unauthorized meter may be incompatible
with the inverter.
Our company will not be responsible for the impact caused by
the use of other appliances.
The 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 our company must be
used.

If the user has other power generation
equipment (such as inverter) at home and
wants to monitor both, the inverter provides
Meter2 communication function to
monitor the power generation equipment.
