Features

1) Easy to install.To configure a solar system, customers only need to connect it with solarpanels and batteries.

2)CPU management andcontrol,modulardesign.

3)LCD display,can visually displayvarious parameters(such as the output voltage, frequency, working mode, etc).

4)Multifunctiondesign,customersdon’t need to buy solar, controller, charger and stabilizer,etc.

5) External batteryconnection, convenient to expand back-up power time; user can connect as manybatteries as needed according to the local sunlight and wind.

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, etc. It can drive almost any kindsof load.

7)Low frequency puresine wave circuit design, good system stability, easy for maintenance, lowfailure rate and long service life (under proper operation, it may be as longas 5 years).

8) Perfectprotection: low voltage protection, over voltage protection, overheatprotection, short-circuit protection, overloads protection.

9) CE / EMC / LVD/RoHS /CCC approvals.

10) 2 years warranty,life-long technical supports.

Function

1. Soleinversion function under inversion mode（only connected to battery）, can be setto 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：FREQUENCY inthe LCD display is set as 02. If the power of the loads that connected to theinverter is lower than 5% of the inverter’s rated power, there will be no output from the inverter.That is to say, only the chip of inverter is working under such condition andthe power consumption is only 1-6W; If the power of the loads that connected tothe inverter is higher than 5% of the inverter’s rated power, then the inverter will automatically startthe inversion function and supply power to the loads within 5s. As shown below:

System introduction under this mode:

1) Only the solar panel charges thebattery.

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

2. UPS function under utility mode（connected tobattery and utility .Can be set as utility first, battery standby mode and battery first, utility standby mode.

2.1. Utility first,battery standby UPS mode: FREQUENCY in the LCD display is set as 01. Whenboth utility and battery are connected to the inverter, utility willsupply power to the loads prior to the battery. When utility is cut off, thebattery will automatically continue to supply power after inversion.

Steps are asfollows:

Step 1: When utility power is available, itwill output directly after voltage being stabilized and charge batteries at thesame time.

Step 2: Whenutility power is cut off suddenly, the inverter will convert DC power to ACpower automatically to ensure uninterrupted power supply within 5ms.

Step 3: Whenutility power becomes available again, it will automatically transfer toutility supplying power to loads and charge batteries at the same time.

See Workflowas below.

System introduction under this mode:

1) Only the solar panel charges thebattery.

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

System introduction under this mode:

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

2) This system is suitable for powersystems built in areas lacking utility or power systems that frequently used inareas with/without utility.

2.2.Battery first, utility standby UPS mode: FREQUENCY in the LCD display is set as03.  When both utility and battery areconnected to the inverter, battery will supply power to the loads prior toutility. When battery capacity is not enough, utility will continue to supplypower automatically.

Stepsare as follows:

Step 1: When battery hasenough power, it will supply power to the loads directly.

Step2: When battery does not have enough power, it will automatically transfer toutility supplying power to the loads.

Step 3: After thebattery is fully charged (e.g. by solar or wind charge controller), it willthen automatically transfer to battery supplying power to the loads.

See Workflowas below.

LCDdisplayed 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 isexpensive and environmental areas where solar power can be fully used to saveutiliypower, such as family solar&wind system and streetlightsolar&wind system.
