Growatt SPH4000 Installation Manual

5.4 SPH System Connection Mode
5.4.1
Conditions for DC Connection
WARNING
The solar modules connected to the inverter must conform to the Class A
requirements of the IEC 61730 standard.
Please use the same brand male and female PV connectors.
SPH single-phase inverter has 2 independent input : MPPT1& MPP
Notice that the connectors are in paired (male and female connectors).
CAUTION
If the inverter is not equipped with a DC switch but this is mandatory in the
country of installation, install an external DC switch.
The following limit values at the DC input of the inverter must not be exceeded:
Types Max current
MPPT1

5.4.2 Connecting the PV Array (DC input)
DANGER
Danger to life due to lethal voltages!
PV array supplies d.c voltage to inverter when exposed to light, before
connecting the PV array , Conver some light screens above PV arrays, ensure
that the DC switch and AC breaker are disconnect from the inverter. NEVER
connect or disconnect the DC connectors under load.
Make sure the maximum open circuit voltage(Voc) of each PV string is less
than the maximum input voltage of the inverter.
Check the design of the PV plant. The Max. open circuit voltage, which can
occur at solar panels temperature of -15℃, must not exceed the Max. input
voltage of the inverter.
WARNING
Improper operation during the wiring process can cause fatal injury to
operator or unrecoverable damage to the inverter. Only qualified personnel
can perform the wiring work.
Please don’t connect PV array positive or negative pole to the ground, it
could cause serious damages to the inverter.
Check the connection cables of the PV modules for correct polarity and
