Dc Cable Connection; Pv Input Configuration - Sungrow SG2.0RS-S User Manual

User Manual
Step 3 Connect the PE wire to ground and the phase lines and the "N" line to AC circuit
breaker. Then Connect the AC circuit breaker to electric board.
Step 4 Make sure all wires are firmly installed via the right torque tool or dragging the cables
slightly.

5.6 DC Cable Connection

Danger of 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.
Risk of inverter damage! Observe the following requirements. Failure to do so
will void guarantee and warranty claims.
• Make sure the maximum DC voltage and the maximum short circuit current
of any string never exceed inverter permitted values specified in "Technical
Data".
• Mixed use of different brand or model of PV modules in a PV string or a
compromised PV string design composed with PV modules from rooftoops
of different orientation may not damage inverter but will cause system bad
performance!
• The inverter enters standby state when the input voltage ranges between
560 V and 600 V. The inverter returns to running state once the voltage
returns to the MPPT operating voltage range, namely, 40 V to 560 V.

5.6.1 PV Input Configuration

• The inverters SG2.0RS-S / SG2.5RS-S / SG3.0RS-S have one PV input with one
MPP tracker.
• The inverters SG3.0RS / SG3.6RS / SG4.0RS / SG5.0RS / SG6.0RS have two PV
inputs, each with independent MPP tracker. Each DC input area can operate
independently.
• The PV strings to the same DC input area should have the same type, the same
number of PV panels, identical tilt and identical orientation for maximum power.
