Grounding Connection
Chart 5.8
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.
Warning
JKS single-phase inverter has 2 independent input MPPT1& MPPT2
Notice: 1. that the connectors are in paired (male and female connectors).
2. in built DC switch isolator is optional in Australia for JKS
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:

5.4.1 Conditions for DC Connection
5.4.2
Connecting the PV Array (DC input)
Danger to life due to lethal voltages!
The photovoltaic array provides DC voltage to the inverter under light.
Before connecting the photovoltaic array, ensure that the DC switch
and AC circuit breaker are disconnected from the inverter when
adjusting the photovoltaic array. Do not connect or disconnect the DC
connector 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.
DANGER
1.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.
2. Please don't connect PV array positive or negative pole to the
ground, it could cause serious damages to the inverter.
3. Check the connection cables of the PV modules for correct polarity
and make sure that the maximum input voltage of the inverter is not
exceeded.
4. Grounding the PV modules
：
The JKS is a transformer less inverter.
That is why it has no galvanic separation. Do not ground the DC
circuits of the PV modules connected to the JKS. Only ground the
mounting frame of the PV modules. If you connect grounded PV
modules to the JKS, the error message "PV ISO Low".
5.Comply with the local requirements for grounding the PV modules
and the PV generator. Jinko recommends connecting the generator
frame and other electrically conductive surfaces in a manner which
ensures continuous conduction with ground in order to have optimal
protection of the system and personnel.
6. Please disconnect the PV DC switch when maintaining the inverter.
