1. Product introduction:
The inverter is suitable for mains power unstable or often off, and important equipment
that requires backup power. This product adopts high-precision DSP control chip,
precise detection circuit、advanced control technology 、modular design is more
convenient for installation and maintenance. Intelligent temperature-regulating fan,
efficient heat dissipation, extending system life. The output is stable, clean and pure
sine wave output. There are four working modes to choose: mains priority mode,
battery priority mode, energy saving mode, and unattended mode. Has short circuit
protection, overvoltage and under voltage protection, overload protection，Overheat /
short circuit automatic restart (automatic restart three times), wide frequency and wide
voltage input, can be used for diesel / gasoline generator input.
1.1.Introduction to working principle
1.2. Introduction to working mode
01 Mains priority
When the mains power is available, the mains power supply power to the load,
and when the mains power is off, the battery will supply power to the load. You can
set the mains power charge the battery or not (PC set).

When the inverter is in battery priority mode and the output load is less than
1%-10% of the power( set by the P7 ,10% default), the AC output will be turn off,
The inverter restarts every 1 minute, and checks whether the load is greater than the
set power. When the connected load is greater than the minimum setting, the inverter
restarts output. This function is to reduce the battery loss and extend the battery
backup time.
03 Battery priority mode
The battery supply power to the load. When the battery voltage is lower than
the set battery voltage(voltage set by PAitem), use mains power supply power to the
load. When the battery voltage is restored , the battery will supply power to the load
again (When battery power is low or PV power is off inverter use mains power
charging for battery or not set by PC）.
04 Mains priority unattended mode
Inverter automatically turn on when connected to mains power or battery
voltage is normal (not include inverter first time use) . But when the battery discharge
voltage lower than battery voltage by set F4 (F4: set the battery low voltage power is
turn off), the power will be turned off. Inverter on only mains power is coming or
turn on by hand.( mains is charging is or not set by PC )
05 Battery priority unattended mode
When the battery voltage is normal ,the inverter automatically turn on and
battery supply power to the load. When the battery is low voltage ,mains power
supply power to the load. When the battery discharge to battery low voltage shutdown
(PL setting), the inverter enters standby and waits for the mains power or solar
charging to battery .When the battery voltage is restored (PN setting),the inverter
automatically turn on .But when the battery
discharge voltage is lower than battery voltage（set by F4), power will be turn
off .Inverter on only mains power is coming or turn on by hand,
2.Operation instruction
1.Opening packing inspection:
Check the package is complete before opening. After opening packing please
check the accessories, The accessories includes 1PCS user manual and check the
inverter is still protected well after transportation.
note:
Read the product manual carefully before using this product.
If you find damage or missing parts, please do not turn on the machine and
contact your dealer.
Please keep the packing box and materials for can be for next delivery if need.

This series of products is very heavy, please handle it carefully .
3.Installation notice:
1. The inverter must be more than 30cm away from the wall, well ventilated, free of
water, flammable gases and corrosives. As shown in the figure:
2.Not good placed in a corner, side, or upside down, away from heat sources. To
avoid direct sunlight, ensure that the front panel, rear panel, and fan inlets have good
ventilation.
3.The environment temperature should be between 0 °C and 40 °C.
4.If the machine is disassembled and used in a low temperature environment, may
happen water condense ,only can work till through dry of machine inside and
outside ,otherwise will be shock risk
5.Please install the inverter near the mains input socket or switch. It is easy to unplug
the mains input or cut off the power supply when meet emergency situation..
6.The external battery should not be exposed. It should be installed in the battery
cabinet..
7.The DC input between inverter should be short as possible
8.Do not stack goods on the inverter.
note:
When the load is connected to the inverter, the load must be turned off before
wiring, and then turned on the loads one by one.
The inverter is connected to a socket with over current protection, and the
machine is safely grounded.
The power outlet should be safely grounded.
Whether the inverter has input or not, the inverter may have output, turning
off the inverter does not ensure that the internal parts are not have power. If
need to make the inverter no output, must turn off all switches first, then turn
off the mains power supply.
Need to touch inductive load: when inductive load such as motor, display,
laser printer. The inverter capacity is three times of the load equipment
starting power .

note:
*If you want to connect the inverter to diesel generator or gasoline generator,
please follow these steps:
1.Turn on the generator, after it works stably, connect generator output to the
inverter input(Confirm the inverter is no-load), then turn on the inverter as
normal. After the inverter starts working, connect the load.
2.Recommended generator capacity is 2-3 times larger than the inverter.
