NOTICE
• Multiple PV inputs can be connected to the inverter, each PV input is congured with a
Maximum Power Point Tracker (MPPT).
• The two input strings per MPPT should be of the same type, the same number of modules,
the same tilt and angle to ensure the best eciency.
• The input strings in deerent MPPTs may dier from each other, like dierent number of
modules and dierent tilt and angle.
• Measure the DC voltage using a 1500V multimeter. If the voltage is less than 0, check the
polarity of the input cables. If the voltage is greater than 1500V, check the number of the PV
modules, and remove some modules.

NOTICE
Seal the PV input terminals using waterproof covers when they are not to be used. Otherwise,
the ingress protection rating will be inuenced.
Step 1 Prepare the DC input cable.
Step 2 Crimp the crimp contacts.
Step 3 Disassemble the PV connectors.
Step 4 Route the DC cable and assemble the PV connectors. Detect the DC input voltage.
Step 5 Plug the PV connectors into the PV terminals.
