The VT-66036103 series hybrid inverter has two MPPT channels, can be connected with
two strings of PV panels. Please make sure below requirements are followed before
connecting PV panels and strings to the inverter:
• 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.
• Disconnect all of the PV (DC) switch during wiring.
Warning:
The fatal high voltage may on the DC side, please comply with electric
