Anti-reverse function connection
If ETC system (connected with grid-tied inverters) requires anti-reverse function, it is operable but
please note:
1. This diagram is only for installation where there is exporting power limit function requirement.
2. For anti-reverse function, it can be set on Screen→Settings→Operation Mode→Self-Use→Power
limit.
3. This diagram will only applies if grid-tied inverter has anti-reverse function build-in. And the
power limitation value can be set on grid-tied inverter.
4. When using anti-reverse function, it would buy about 500W from the grid.
ETC series inverter complies with IEC 62109-2 13.9. Fault indicator LED on the inverter cover will light
up and the system will email the fault information to customer.
