Features

1) Easy to install. Toconfigure a solar system, users just need to connect it with solar panels andbatteries.

2)CPU management,Intelligentcontrol,modular design

3)LEDs LCD display. LCDcan display various parameters(such as the output voltage, frequency, workingmode)

4)Multifunction design,AVR UPS function. Users don’t need to buy solar, controller, AC charger or stabilizer.

5)External battery connection, it’s convenient for users to expand use time andback-up power time

6)With superload-carrying ability and high load capacity, this series of  inverters can not only drive resistance load;but also various kinds of inductive loads such as motor, air conditioner,electric drills, fluorescent lamp, gas lamp. It can drive almost any kinds ofload

7)Low frequency puresine wave circuit design, stable quality, easy to maintenance, low failure rateand long service life (under proper operation,it can last at least 5 years)

8) Perfect protection: lowvoltage protection, high voltage protection, over temperature protection, short-circuitprotection, overload protection

9) CE / EMC / LVD/ RoHS/FCC approvals

10) 2 years warranty, life-long technical support

Function

1.   Sole inversion function under inversion mode（only connected to battery）,can be set to normal working mode and sleep mode

1.1  Normal working mode：FREQUENCY in the LCD display is set as 01. No matter whether there are AC loads connected to the inverter or not, the inverter’s output terminal will always have voltage ready to supply power to the loads. Under this mode, the LCD will be displayed as bellow:

1.2 Sleep mode：FREQUNCY in the LCD display is set as 02.If thepower of the connected AC loads is lower than 5% of the inverter’s rated power,there will be no output from the inverter. Only the chip of inverter is working.The power consumption of the inverter is only 1-6W. The LCD shows the outputvoltage 0. If the power of the connected loads is over 5%,then the inverterwill automatically convert DC to AC to supply power for the loads within 5s.The LCD shows the output voltage. As shown below:

System introduction under this mode:

1) Only the solar panel charges the battery

2) Independent sole off-grid solar power system; suitable for areas that are      lack of utility or have rich solar energy

2. UPS function  When the inverter is connected to battery andutility, users can set it to utility first (AC first) battery standby mode orbattery first (DC first)utility standby mode.

2.1.Utilityfirst (AC first) battery standby mode : FREQUENCY in the LCD display is set to 01.When utility and battery are connected to the inverter, utility will supplypower to the loads prior. When utility is cut off, the battery willautomatically continue to supply power via power inverter.

   Steps are as follows:

   Step 1: When utility is available, it will drivethe loads directly after voltage being stabilized and at the same time chargebatteries via power inverter .

   Step 2: When utility is cut off, theinverter will convert DC to AC automatically to ensure uninterrupted powersupply within 5ms.

See Workflow as below:

LCD displayed as bellow:

Kindly note:

1) There are 2 ways to charge thebattery, utility and solar panel

2) This system is suitable for powersystems built in areas that are lack of utility. Or people can use solar andutility at the same time.

2.2. Battery first(DC first)utility standy mode: FREQUENCY in the LCD display is set as 03. When utility andbattery are connected to the inverter, battery will supply power to the loadsprior to utility. When battery capacity is not enough, utility will continue tosupply power automatically.

Steps are as follows:

Step 1: When battery is available, it will drive the AC loadsvia power inverter.

Step 2: When battery does not have enough power, it willautomatically transfer to utility supplying power to the loads

Step 3: After the battery is fully charged (e.g. by solar orwind charge controller), it will automatically transfer to battery supplyingpower to the loads via power inverter.

See Workflow as below:

LCD displayed as bellow:

System introduction under this mode:

1) There is only way to charge the battery: solar panel

2) This system is suitable for areas where electricity is expensive and environmental areas where solar power can be fully used to save utiliypower, such as family solar&wind system and streetlight solar&wind system
