15.3 EV-Charger Application
Introduction of EV-Charger application
The X3-EVC series are AC EV charger and intended for charging electric vehicles. It
should be installed in a fixed location and connected to the AC supply. The EV-Charger
can communicate with other devices or systems (inverter, meter, CT, third-party charger
management platform, etc.) to realize intelligent control of charging process.

Charging modes
The EV-Charger can work with the inverter system which supports communication with
it to form an intelligent photovoltaic, storage and EV charging energy system. Through
communicating with the inverter, the EV-Charger can obtain the current information of the
grid and PV and realize the smart control of different charging modes.
• Green mode: In Green mode, the EV-Charger will maximize the use of surplus
power generated from the inverter. According to the minimum start-up charging
power, the charging current can be divided into two levels as 3 A and 6 A. The
default level is 3 A.
• Eco mode: In Eco mode, the charging power is continuously adjusted according
