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:
Model name
Max.current input A
Max.current input B
SP6000M
11A
11A
5.4.3
Connecting the PV Array (DC input)
danger
Before connecting the PV array, 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 550Vdc.
Check the design of the PV plant. The Max. open circuit voltage, which can
occur at solar panels temperature of -10
℃
, 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.
5.5 Grounding the inverter
The inverter must be connected to the AC grounding conductor of the power distribution grid via the
ground terminal (PE) .
warning
Because of the transformerless design, the DC positive pole and DC
negative pole of PV arrays are not permitted to be grounded.
