Dc Cable Connection; Pv Input Configuration - Sungrow SG5KTL-MT User Manual

5 Electrical Connection
Observe the terminal layout on the block. Do not connect the phase wires to
"PE" terminal or PE wire to "N" terminal. Otherwise, unrecoverable damage to
the inverter may follow.
step 6 Connect AC circuit breaker to utility grid.
step 7 Make sure all AC cables are firmly installed.

5.5 DC Cable Connection

Electric shock!
The PV array will generate lethal high voltage once exposed to sunlight.
Make sure the PV array is well insulated to ground before connecting it to the
inverter.
There is a risk of inverter damage! The following requirements should be met.
Failure to do so will void guarantee and warranty claims.
Make sure the maximum voltage of each string is always less than 1100 V.
•
The inverter enters the standby state when the input voltage ranges between
•
1,000V and 1,100V. The inverter returns to the running state once the
voltage returns to the MPPT operating voltage range, namely, 200 to 1,000V.
Make sure the maximum short circuit current on the DC side is within the
•
permissible range.

5.5.1 PV Input Configuration

The inverter has two PV input areas PV1 input and PV2 input, each with its MPP tracker.
Each PV input operates independently and has its own MPPT. In this way, string
structures of each PV input may differ from each other, including PV module type,
number of PV modules in each string, angle of tilt, and installation orientation.
