5.1 Electrical Connection Overview
This product supports the following power grid systems.
Note: If the power grid system contains a N wire, the neutral to ground voltage should be lower than 10V.
➢ The connection modes between the N wire and PE wire and the GRID port and EPS port of the
inverter may be vary in different regions. Please consult your local regulatory requirements.
➢ The GRID port and EPS AC port of the inverter have built-in relays. When the inverter works in off-
grid state, the built-in GRID relay will be open; when the inverter works in on-grid state, the built-in
GRID relay will be closed.
➢ When the inverter is powered on, the EPS AC port will be charged; if you need to perform
maintenance of the EPS load, please power off the inverter first in order to avoid electric shock.
