No. Parts Description
7 BACK-
UP load
breaker
The AC breakers should be prepared by customers. Recommended
specications:
• GW15K-ET: nominal current ≥32A, nominal voltage ≥400V
• GW20K-ET: nominal current ≥ 40A, nominal voltage ≥ 400V
• GW25K-ET: nominal current ≥50A, nominal voltage ≥400V
• GW29.9K-ET, GW30K-ET: nominal current ≥ 63A, nominal voltage ≥
400V
8 Bypass
switch
To keep the back-up loads working when the inverter is powered o
for maintenance, bypass switches are recommended. Recommended
specications:
• GW15K-ET: nominal current ≥32A, nominal voltage ≥400V
• GW20K-ET: nominal current ≥ 40A, nominal voltage ≥ 400V
• GW25K-ET: nominal current ≥50A, nominal voltage ≥400V
• GW29.9K-ET, GW30K-ET: nominal current ≥ 63A, nominal voltage ≥
400V
9 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 qualied 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.
10 Power
distribution
panel
• A distribution board should be prepared by the customer.
• Nominal current of the distribution board ≥2 x N x I
max
(N refers the
quantity of the inverters in the system; I
max
refers to the maximum
output current of the inverter.
11 Load
breaker
Depends on the actual loads.
