Page 6: Installation
INSTALLATION Unpacking and Inspection Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. You should have received the following items inside of package: The unit x 1 User manual x 1 Communication cable x 1 ... -
Page 7: Battery Connection
Install the unit by screwing two screws. It’s recommended to use M4 or M5 screws. Battery Connection CAUTION: For safety operation and regulation compliance, it’s requested to install a separate DC over-current protector or disconnect device between battery and inverter. It may not be requested to have a disconnect device in some applications, however, it’s still requested to have over-current protection installed. - Page 8 5. Insert the battery wires flatly into battery connectors of inverter and make sure the bolts are tightened with torque of 2 Nm in clockwise direction. Make sure polarity at both the battery and the inverter/charge is correctly connected and conductors are tightly screwed into the battery terminals. Recommended tool: #2 Pozi Screwdriver 6.

Page 9: Ac Input/Output Connection
AC Input/Output Connection CAUTION!! Before connecting to AC input power source, please install a separate AC breaker between inverter and AC input power source. This will ensure the inverter can be securely disconnected during maintenance and fully protected from over current of AC input. The recommended spec of AC breaker is 32A for 3KVA and 50A for 5KVA. -
Page 10: Pv Connection
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 manufacturer of air conditioner if it’s equipped with time-delay function before installation. -

4. Check correct polarity of wire connection from PV modules and PV input connectors. Then, connect positive pole (+) of connection wire to positive pole (+) of PV input connector. Connect negative pole (-) of connection wire to negative pole (-) of PV input connector. Screw two wires tightly in clockwise direction. Recommended tool: 4mm blade screwdriver Final Assembly After connecting all wirings, please put bottom cover back by screwing two screws as shown below. -
