No. Parts Description
1 PV string PV string is composed of series connected PV panels.
2 Battery • Select the battery model according to the inverter model and the
approved battery list.
• In parallel system, it is recommended to use batteries of the same brand,
model, and capacity.
• Do not connect one battery to more than one inverter at the same time.
Otherwise, it may cause damage to the inverter.
• When the parallel system is connected to the power grid, the SOC of
each battery may be unbalanced.
3 Battery
breaker • It must meet the local regulatory requirements. Recommend customers
to prepare 2 horsepower DC switch.
• Recommended specifications:
• For GEH6.0-3U-20 and GEH8.0-3U-20 : the nominal current is ≥ 40A
and the nominal voltage is ≥ 720V DC.
• Other models: the nominal current is ≥ 50A and the nominal voltage is
≥ 720V DC
4 Inverter • Supports the GEH 6.0-15kW inverter. It is recommended to use the same
model of inverter in the same system. If there is a need, different models
of inverters can also be used.
• The system supports up to 6 inverters. The power limit of the parallel
system must meet local regulatory requirements.
• When using a parallel system, if you need to achieve functions such as
load control, remote shutdown, DRED/RCR, etc., please connect the
communication cable to the master inverter.
• When the master inverter in the parallel system malfunctions, the parallel
system cannot function properly; When any slave inverter in the parallel
system experiences an abnormality, except for the malfunctioned one, all
other inverters can operate normally.
5 Ezlink Module • In parallel system, only Ezlink module is supported for networking.
• Only one Ezlink module needs to be installed in the same system. The
inverter connected to the Ezlink module defaults to the master inverter,
while other inverters are slave inverters. The master inverter can issue
commands to the slave inverter. If other inverters are installed with Ezlink
modules, it will cause abnormal communication.
