NOTE:
This MPPT charger has a built-in PV breaker on the side panel of the unit for added safety,
protection and to assist with code compliance. (For local codes, check with your local AHJ.)
Ensure the PV breaker is in the off position prior to installing PV wires.
WARNING
We recommend all wiring be performed under the guidance of a licensed professional.
PV Wire Installation:
1. Remove insulation sleeve 10 mm/0.4" for positive and negative conductors.
2. Check correct polarity of connection cable from PV modules and PV input connectors. Then, connect
positive pole (+) of connection cable to positive pole (+) of PV input connector. Connect negative
pole (-) of connection cable to negative pole (-) of PV input connector.
3. Ensure PV cables are tightened to the proper torque specifications in the chart below.
PV Module Selection:
When selecting PV modules, please be sure to take into account that the temperature-adjusted open
circuit voltage (VOC) of the PV modules should not exceed the max PV array open circuit voltage of the
charger.
Operation and Display Panel
