Description
1
PV string
The PV string consists PV panels series connected.

Battery
• Select the battery based on the approved battery list matched with the
inverter.
• Batteries of the same brand, model, and capacity are preferred in a
parallel system. If necessary, batteries of the different brand, model, and
capacity are also supported.
• Do not connect a single battery to multiple inverters. Otherwise, the
inverters may be damaged.
•
All the batteries in the parallel system are Soc balanced when the
system is working on-grid.

Battery
breaker
Select the breaker in compliance with local laws and regulations. 2P
DC breakers of the following specifications are recommended: nominal
current≥63A, and nominal voltage≥1000V.
4
Inverter
• Supports GEH 15 -30kW inverters. Inverters of the same model are
preferred in one parallel system. If necessary, inverters of the different
models are also supported.
•
When the inverter models are different in the parallel system, the one
with the highest power should be set as the master inverter.
•
At most 6 inverters can be connected in the parallel system. The
power limit of the system shall meet the requirements of local laws and
regulations.
• To realize functions such as load control, remote shutdown, DRED/
RCR, the communication cable have to be connected to the master
inverter.
• The parallel system cannot work properly once the master inverter is
abnormal. When any salve inverter is abnormal, the system, except for
the abnormal inverter, still works properly.
5
Ezlink
• In parallel scenarios, only the smart dongle Ezlink is supported for
parallel networking.
• Only one Ezlink 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 master inverter
sends commands to slave inverters. The system communication may be
abnormal if other inverters install with the Ezlink.
6
AC breaker An external AC breaker needs to be installed on the AC side of the inverter.
The AC breakers should be prepared by customers. 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
