PV Connection
CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between inverter
and PV modules.
WARNING! All wiring must be performed by a qualified personnel.
WARNING! It's very important for system safety and efficient operation to use appropriate cable for PV
module connection. To reduce risk of injury, please use the recommended cable size as below.
NOTICE! When only one MPPT is used, please use MPPT1 first.

PV Module Selection:
When selecting proper PV modules, please be sure to consider the parameters below:
1.
Open circuit Voltage (Voc) of PV modules can’t exceed the maximum voltage of the PV array open circuit of
the inverter.
2. Open circuit Voltage (Voc) of PV modules should be higher than the minimum voltage of the battery.
Please follow the steps below to implement PV module connection:
1. Remove insulation sleeve 10 mm from positive and negative conductors.
2. Check the correct polarity of connected 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. Make sure the wires are securely connected.

Number of MPPT 2
Max. PV Array Open Circuit Voltage 145Vdc
PV Array MPPT Voltage Range 60~115Vdc
Min. battery voltage for PV charge 34Vdc
CAUTION: Important
Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely, it may cause utility
short-circuited when these inverters are worked in parallel operation.
CAUTION: Appliances such as air conditioner are required at least 2~3 minutes to restart because it’s required
to have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in a
short time, it will cause damage to your connected appliances. To prevent this kind of damage, please check with
the manufacturer of the air conditioner if it’s equipped with time-delay function before installation. Otherwise,
this inverter/charger will cause overload fault and cut off the output to protect your appliance but sometimes it
still causes internal damage to the air conditioner.
