6.6 EPS Connection
A. EPS Wiring
EPS mode can be achieved by two different type of wiring methods. One is using the internal bypass to
wire the house emergency loads on the EPS port from inverter. Another is using external contactor to

Note: the inverter default is set as “External” EPS wiring mode, it can be set to “Internal” via
display setting “Menu – Setting – Feature – Bypass Relay”.
