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
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.

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.
o
·The ambient temperature should be between 0 C and
o
40 C to ensure optimal operation.
·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.

DC Wiring Suggestion
It is suggested to keep battery bank as close as possible to inverter. battery cable length 1m is suggested.
Please find following minimum wire size. If DC cable longer than 1 m, please use thicker battery cables to bear
power current going though.

Please connect cable size thicker enough, or connect several combined thin cables together to be same strong.
Battery bank should be kept close to inverter; The shorter and thicker cables, the better the system performance.
Please follow battery connection steps below:
Assemble battery ring terminal.
Connect all battery packs as units requires.
Battery cable and terminal size suggestion:
It's suggested to connect at least 100Ah capacity battery pack for 1KW-3KW models, at least 200Ah for 4KW-6KW
models.
NOTE: Please only use sealed lead acid battery or sealed GEL/AGM lead-acid battery.
Insert the ring terminal of battery cable into inverter to battery connector, make sure the bolts are tightened
with torque of 2-3Nm. Pay special attention to battery back and inverter are connected rightly, also 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.
CAUTION!!Do not place anything between the flat part of the inverter terminal and
the ring terminal. Otherwise, overheating may occur.
CAUTION!!Do not apply antioxidant substance on the terminals before terminals
are connected tightly.
CAUTION!! Before making the final DC connection or closing DC breaker/ dis-
connector, be sure positive(+) must be connected to positive(+) and negative(-)
must be connected to negative(-).
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 inverter can be disconnected safely during maintenance and fully protected
from over current of AC input.
Suggestion AC breaker: 50A for 1KW-3KW, 80A for 4KW-6KW.
CAUTION!! Please don't connect the output wring to "Grid" terminal or connect the grid wring to the "Load" terminal.
WARNING! All wiring must be performed by a qualified personnel.
WARNING! It's very important to use appropriate cable for Grid connection for system safety and efficient operation.
To reduce injury risk, please use the proper suggested cable size as below.
AC Wiring
We recommend using 10-16AWG wire to connect AC terminal block.
There are 3 different ways to connect AC wire to terminal block. All wirings are CE compliant, call our tech support if
you are not sure about how to wire any part of your inverter.

Please follow steps below to implement Load/Grid connection:
Before Load/Grid connection, be sure to open DC protector first.·
Remove insulation sleeve 10mm for six conductors. And shorten phase L and neutral conductor N 3 mm.·
Insert grid wires according to polarities indicated on terminal block and tighten terminal screws. Be Sure to ·
connect PE protective conductor( )first.

WARNING:
Be sure that AC power source is disconnected before hard-wire it to the unit.
·Then, insert Load wires according to polarities indicated on terminal block and tighten terminal screws. Be sure
to connect PE protective conductor( )first
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
will be triggered overload fault and cut off output to protect your appliance but sometimes it still causes internal
damage to the air conditioner.
·Make sure the wires are securely connected

AGS function
AGS function information
The AGS function is that the inverter will start the generator automatically via the dry contact when the battery is
low voltage.
Note:
The generator must have dry contact function.
If you connect AC grid and Generator to Inverter input at the same time, the interlock device should be installed
between generator output and inverter input. (To ensure the utility and generator will not provide power to
inverter at the same time. It doesn’t need to be installed if only connect generator).
