• The open-circuit voltage and short-circuit current of PV string should not exceed
the reasonable range of the inverters.
• The isolation resistance between PV string and ground should exceed 300 kΩ.
• The polarity of PV strings are correct.
• Use the DC plugs in the accessory.
• The lightning protector should be equipped between PV string and inverter.
