1. Introduction
This is a DC-to-AC inverter with integrated solar battery charger, an energy-saving solution or an
automotive inverter (hereinafter referred to as “inverter”)
The inverter accepts input power source from AC mains (utility), battery, and PV (solar) string and
switches between various operation modes automatically depending on the operational conditions.
The PV (solar) string can be set as priority to supply the loads without consuming the power from AC
mains, as long as sufficient sunlight is present.
The battery can be charged by both AC mains and PV (solar) string with intelligent charging control.
Key features:
Built-in enhanced AC charger & solar charger controller up to 50A
Selectable input voltage ranges, charging priority setting, AC or solar power priority setting
Auto restart when AC recovery
User-friendly LCD and LED indications with setting function
With the environmental temperature control charge management
Rack design & wall-mounted design for flexible installation
Intelligent 3-stage charger control for efficient charging and preventing overcharge
Multiple protection: low battery alarm, low battery shutdown, over charge protection, overload protection,
over temperature protection, short circuit protection
Fan speed automatic adjust, Low noise
Battery Cut off point setting, Buzzer alarm ON/OFF setting
2. Important Safety Warning(Save These Instructions)
Before using the inverter, please read all instructions and cautionary markings on the unit, this
manual and the batteries.
Conventions used:
WARNING! Warnings identify conditions or practices that could result in personal injury.
CAUTION! Caution identify conditions or practices that could result in damaged to the unit or other

General Precaution-
WARNIN G! The unit is designed for indoor use. Do not expose this unit to rain, snow or liquids of any
type.
WARNIN G! To reduce risk of injury, only use qualified batteries from qualified distributors or
manufactures. Any unqualified batteries may cause damage and injury. Do not use old or overdue batteries.
Please check the battery type and date code before installation to avoid damage and injury.
WARNIN G! It’s very important for system safety and efficient operation to use appropriate external
battery cable. To reduce risk of injury, external battery cables should be UL certified and rated for 75℃ or
higher. And do not use copper cables less than 10AWG.
WARNIN G! Do not disassemble the inverter. Contact with the qualified service center when service or
repair is required.
WARNIN G! Provide ventilation to outdoors from the battery compartment. The battery enclosure should
be designed to prevent accumulation and concentration of hydrogen gas at the top of the compartment.
WARNIN G! Use insulated tools to reduce the chance of short-circuit when installing or working with the
inverter, the batteries, or other equipments attached to this unit.
WARNIN G! For battery installation and maintenance, read the battery manufacture’s installation and
maintenance instructions prior to operating.
Personnel Precaution-
WARNIN G! Careful to reduce the risk or dropping a metal tool on the batteries. It could spark or short circuit
the batteries and could cause an explosion.
WARNIN G! Remove personal metal items such as rings, bracelets, necklaces, and watches when working with
batteries. Batteries can produce a short circuit current high enough to make metal melt, and could cause
severe burns.
WARNIN G! Avoid touching eyes while working near batteries.
WARNIN G! Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
WARNIN G! Never smoke or allow a spark or flame in vicinity of a battery.
