Bypass
switch
To keep the back-up loads working when the inverter is powered off
for maintenance, bypass switches are recommended. Recommended
specifications:
•
GEH15-3U-10: nominal current ≥32A, nominal voltage ≥400V
•
GEH20-3U-10: nominal current ≥ 40A, nominal voltage ≥ 400V
•
GEH25-3U-10: nominal current ≥50A, nominal voltage ≥400V
•
GEH29.9-3U-10, GEH30-3U-10: nominal current ≥ 63A, nominal voltage
≥ 400V

Smart meter •
Prepare the GM330 smart meter for parallel system separately.
• Check whether the included CT meets requirements based on actual
needs. If not, refer to the manual of the smart meter and prepare a
qualified CT.
• Only one smart meter is required in one parallel system. The
inverter connecting to Ezlink and smart meter is considered as the
master inverter, while all the others are slave inverters. The system
communication may be abnormal if other inverters install with a smart
meter.
9
Distribution
board
•
A distribution board should be prepared by the customer.
•
Nominal current of the distribution board ≥2 x N x Imax (N refers the
quantity of the inverters in the system; Imax refers to the maximum
output current of the inverter.
10
Load
breaker
Depends on the actual loads.
11
WiFi/LAN
module
In the parallel system, the slave inverters should install the WiFi or LAN
module delivered with the inverter.
