• 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.
