The following figure shows the open-circuit voltage limits at different altitudes. Before config-
uring the PV panels, need to take this derating curve in consideration under high altitude
situation.

Open-circuit Voltage Derating Curve
5.6.2 Assembling the PV Connectors
High voltage may be present in the inverter!
•
Ensure all cables are voltage-free before performing electrical operations.
•
Do not connect the AC circuit breaker before finishing electrical connection.
•
Use MC4 DC terminals if the maximum input voltage is no more than 1,000 V.
•
Use MC4-Evo2 DC terminals if the maximum input voltage is greater than 1,000
V. To purchase the MC4-Evo2 DC terminals, contact SUNGROW.
•
Select appropriate DC terminals as required above. Otherwise, SUNGROW shall
be held no liability for the damage caused.
SUNGROW provides corresponding PV connectors in the scope of delivery for
quick connection of PV inputs. To ensure IP65 protection, use only the supplied
connector or the connector with the same ingress of protection.
step 1 Strip 7 mm–8 mm of the insulation from each PV cable.
