Before designing and during the production, the safety of operators and products all have been

considered. Please following this users instructions strictly to operate or install the machine in

case of personal injury or accident occur.

(1)The installation of the inverter should be done by professionals or under the assistance of the local

dealer.
(2)Verify whether the input DC voltage range meets the requirements ±15% and the correctness of

voltage polarity.
(3)Confirm the grade of load device voltage ,power should not be more than rated output power of

the inverter

(4)Do not flow any liquid inside the inverter, or with a damp cloth to wipe the machine casing. Can

not be directly Contact the inverter input and output terminals when the machine is running,

especially with wet hands, otherwise electric shock injury will occur.

(5)If you need to change the working environment under the normal working state, do not change its

connection, your operated should be assistance and confirmation by the professionals or supplier.

(6)The operating environment of inverter should be well-ventilated, temperature range -20-45

degrees, keep away from the ignition sources spot and direct sunlight, Can not run in the

condensation, dust environment. During the operating, the heat is normal phenomenon, should

maintain the ventilation, clean installation environment, in particular, can not block the ventilation

holes.

(7)Minors can not use this product.

(8)Confirm weather the inverter can be connected with the earth wire,Live line and Zero line can not

be reversed, the diameter shall comply with the conditions of safe use, for the cable, keep it as

short as possible.

(9)Do not open the case of the inverter without any special circumstances; otherwise we will not

classify it as product warranty matter.

(10)Please keep this manual for future reference.

Attention:

A.Do not use in life-sustaining equipment without permission.

B.Do not use in high precision electrical equipment,need professional person`s confirmation.

C.Use to power computer,built-in power supply should be brand power.

Warring

：

No battery reverse connect.No wire zone line reverse connect.
Do not using during flammable and explosive air. Pay attention to spark.

Please connect battery first then no disorder.

unction:

:Description of the diagram

A、Give priority to the use of AC

Step1：When Utility Grid input is normal,AC power the load directly and recharge battery.

Step2：When Utility Grid shut off,the system will switch to give priority to the use of DC in 5ms
automatically, ensuring normal working.

Step3：When Utility Grid is recovery, system will switch to give priority to use of AC and recharge

battery.

B、Give priority to the use of DC

Recharge battery mainly from solar energy,Utility Grid assist recharging.

Step1：When Utility Grid is normal,voltage of battery higher than 11V,DC turn into AC through
inverter and power load.

Step2：When the voltage of battery is lower than 11V,the system switch to Utility Grid automatically
and recharging battery.

Step3：When the voltage of battery up to 13.5V, system switch to photovoltaic power and power the
load.

Step4：When both Utility Grid and photovoltaic power broke down, battey will shut off when voltage
lower than 10v
If Utility Grid is normal,AC will power load and recharge the battery.

If Utility Grid still broke down, photovoltaic power recharge battery until voltage up to 12v and turn
on with conversion mode.

(2): Intelligent charge

1) Charge different kinds of batteries,refer to the parameter of product(page five of this

manual)

2)Three charge stages

Stage 1: the charger will run at full current in CC mode until the charger reaches the boost voltage.

Activate battery,promote power.(constant-current charging)

Stage2: the charger will keep the boost voltage in Boost CV mode.give battery enough time to absorb

energy,protect battery and electrode form over charge,extend life time.(constant-voltage charging)

Stage3:when the battery is full,It will turn into float voltage automatically to keep full power and

check battery power all the time,stop working when charge finish to save power..(Float charging)

(4)Power save mode(detect time is 5s):when boot under this mode,no load power consumption is

1w-6w,only CPU works,It will detect system cyclically,when load more than 30w ,system will boot

and enter normal working mode ,when load is less than 30w,It will enter energy-saving mode

in5s.This mode save unnecessary power.

after-sale maintenance;

3、LED + LCD display, a visual display of all operating parameters of the machine,

4、High conversion efficiency,The conversion efficiency is 90-95% in half load situation ; more

than 99% in commercial situation; low-consumption, under the save power mode,the consumption is

between 1W ~ 6W; High efficiency and energy conservation.

5、Increased electricity auxiliary charging function; powerful charging function, three-stage

intelligent charging for different types of batteries, such as sealed lead-acid batteries, open lead acid

batteries, gel batteries, seven kinds of batteries,Note:lithium batteries need to setting as customers

use specifications before the delivery.
