• The positive connection cables of the PV modules must be equipped with the positive
DC connectors.
• The negative connection cables of the PV modules must be equipped with the
negative DC connectors.
• At an ambient temperature over 10℃, the open-circuit voltage of the PV strings must
not exceed 90% of the maximum DC input voltage of the inverter. This prevents the
voltage from exceeding the maximum DC input voltage of the inverter at lower
ambient temperatures.
