WARNING!

This manual contains important instructions for all Inverter/Charger models that shall be
followed during installation and maintenance of the inverter.

The following cases are not within the scope of warranty

1. Out of warranty.

2. Series number was changed or lost.

3. Battery capacity was declined or external damaged.

4. Inverter was damaged caused of transport shift, remissness, ect external factor

5. Inverter was damaged caused of irresistible natural disasters.

6. Not in accordance with the electrical power supply conditions or operate environment
caused damage.

General Precautions

Before using it, read all instructions and markings:
(1) inverter (2) battery (3) user manual

CAUTION:

To reduce risk of injury, charge only lead-acid rechargeable batteries. If customer use flooded batteries, batteries 1.

must be maintained regularly. Other battery types may cause damage and injury.

Do not expose it to rain, snow or any type liquids. Inverters are designed for indoor use.2.

3. Do not disassemble it. Take it to qualified service center when service or repair is needed.

4. To prevent the risk of electric shock, disconnect all wiring before attempting any maintenance or cleaning. Only

turning off the unit will not reduce the risk.

WARNING:

1. Provide ventilation from the battery compartment to outdoors. The battery enclosure should be designed to

prevent accumulation and concentration of hydrogen gas at the top of the compartment.

2. NEVER charge a frozen battery and connect such 12V/24V/48V batteries to inverter.

3. Input/output AC wiring mustn’t be less than 12AWG and not rated for 75 °C or higher. Battery cable mustn’t be

rated for 75°C or higher and should be no less than 4AWG /6AWG gauge.

4. Pay special attention when working with metal tools around batteries. Batteries short-circuiting could cause an

explosion.

5. Read the battery installation and maintenance instructions carefully before operating.

Personnel Precautions

1. Better to prepare plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.

2. Avoid touching eyes while working near batteries.

3. NEVER smoke or allow a spark or flame near batteries.

4. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with batteries.
Batteries may provide heavy short-circuit current, which would be enough to make metal melt and causes severe
burn.

5. If a remote or automatic generator start system is used, disable the automatic starting circuit or disconnect the
generator to prevent accident during servicing

Unpacking and inspection

Before installation, please inspect whole unit. Be sure that nothing inside the package is damaged. You should have
received the following items inside of package.

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 read the

LCD display clearly.

·For proper air circulation to dissipate heat, require a
clearance about 50 cm to the side and 80 cm above
and below the unit.

·The ambient temperature should be between 0 C and

o

40 C to ensure optimal operation.

o

·The recommended installation position is to be
adhered to the wall vertically.

·Be sure to keep other objects and surfaces as shown
in the diagram to guarantee sufficient heat dissipation
and to have enough space for removing wires.

SUITABLE FOR MOUNTING ON
CONCRETE OROTHER NON-COMBUSTIBLE
SURFACE ONLY.
