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 Preparation Before connecting all wirings, please take off bottom cover by removing two screws as shown below. Mounting the Unit Consider the following points before selecting where to install:  Do not mount the inverter on flammable construction materials. Mount on a solid surface Install this inverter at eye level in order to allow the LCD display to be read at...

Install the unit by screwing two screws. It’s recommended to use M4 or M5 screws. Battery Connection This model can be operated without battery connection. Connect to battery if necessary. CAUTION: For safety operation and regulation compliance, it’s requested to install a separate DC over over-currentprotector or disconnect device between battery and inverter. It may not be requested to have a disconnectdevice in some applications, however, it’s still requested to have over-current protection installed. Please referto typical amperage in below table as required fuse or breaker size. WARNING!...

4. 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 WARNING: Shock Hazard Installation must be performed with care due to high battery voltage in series. CAUTION!! Before making the final DC connection or closing DC breaker/disconnector, be sure positive (+) must be connected to positive (+) and negative (-) must...

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 3.5KW and 50A for 5.5KW. CAUTION!! There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect input and output connectors. WARNING! All wiring must be performed by a qualified personnel. WARNING! It's very important for system safety and...

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. Otherwise, this inverter/charger will trig overload fault and cut off output to protect your appliance but sometimes it still causes internal damage to the air conditioner....

3. Check correct polarity of wire connection from PV modules and PV input connectors. Then, connect positivepole (+) 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. Communication Connection Please use supplied communication cable to connect to inverter and PC. Insert bundled CD into a computer...

OPERATION Power ON/OFF Side view of unit Once the unit has been properly installed and the batteries are connected well, simply press On/Off switch (located on the button of the case) to turn on the unit. Operation and Display Panel The operation and display panel, shown in below chart, is on the front panel of the inverter. It includes three indicators, four function keys and a LCD display, indicating the operating status and input/output power information. LED Indicator LED Indicator Green Green Red Output is powered by utility in Line mode. Output is powered by battery or PV in battery mode....
