Installation and Wiring
6.1 Decide Application Scenario
The EV-Charger offers different application scenarios and the communication connection
is different under different application scenario. Please decide the application scenarios
before installation.
Home Scene
• Communication with CT/Meter
The EV-Charger can work with the inverter system which does not support communication
with it to form an intelligent photovoltaic, storage and EV charging energy system. Through
communicating with CT or meter, the EV-Charger can obtain the current information and
realize the smart control of different charging modes. However, if the inverter has zero
injection requirement, Green or Eco charging mode of the EV-Charger may not work
normally.
The EV-Charger can also work without the inverter system, but realize the smart control of
the charging modes through communicating with CT or meter.
