Page 3: About This Manual
ABOUT THIS MANUAL Purpose This manual describes the assembly, installation, operation and troubleshooting of this unit. Please read this manual carefully before installations and operations. Keep this manual for future reference. Scope This manual provides safety and installation guidelines as well as information on tools and wiring. SAFETY INSTRUCTIONS WARNING: This chapter contains important safety and operating instructions. -
Page 4: Introduction
INTRODUCTION This is a multi-function inverter/charger, combining functions of inverter, solar charger and battery charger to offer uninterruptible power support with portable size. Its comprehensive LCD display offers user-configurable and easy-accessible button operation such as battery charging current, AC/solar charger priority, and acceptable input voltage based on different applications. -

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 three screws. Battery Connection CAUTION: To 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 3. Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the bolts are tightened with torque of 2-3 Nm. Make sure polarity at both the battery and the inverter/charge is correctly connected and ring terminals are tightly screwed to the battery terminals. WARNING: Shock Hazard Installation must be performed with care due to high battery voltage in series.

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 20A for 2KVA, 32A for 3KVA. -
Page 10: Pv Connection
5. Make sure the wires are securely connected. CAUTION: Important Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely, it may cause AC short-circuit 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. -
Page 11: Final Assembly
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 and follow on-screen instruction to install the monitoring software. For the detailed software operation, please check user manual of software inside of CD. -
