The AC side terminal is clear, Connect cables into relevant
terminals as the figure 5.6.3
The cables length should not exceed 50 m, the resister of the
cable will consume inverter output power , finally reduce the
inverter efficiency .
NOTICE

Connect to PV Panel (DC input)
Risk of electric shock and fire, use only with PV modules, and
with a maximum system voltage of 450Vdc for Growatt1500-
US,500V for Growatt2000-US &Growatt3000-US.
DANGER
Electric shock hazard , the DC conductors of this photovoltaic
system are normally ungrounded but will become
intermittently grounded without indication when the inverter
measures the PV array isolation.
Because of the transformer less design, the DC positive pole
and DC negative pole of PV arrays are not permitted to be
grounded.
Do not disconnect the DC connectors under load!
Input connection terminal
Suggestions for the PV modules of the connected strings:
Same type
Same quantity of PV modules connected in series
Wiring inverter in parallel
The inverter can be connected in parallel in order to obtain more power, each
inverter shall connect to its own PV array, cannot connect a single PV array to
more than one inverter. That will cause the inverter to work abnormally, the
worst condition inverter will be damaged.
