Feature

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

2.CPU management ,intelligent control，modular design, User-friendly LCD display

3.Built-in MPPT controller, high charging efficiency

4.Low power consumption, high conversion efficiency

5.Intellectual，multi-function, convenient for customers with different using environment to fully use the solar energy

6.External battery connection, convenient to expand back-up power time

7.Strong load-carrying ability, low failure rate, easy maintenance and long service life (under proper operation, it may be as long as 5 years)

8.Perfect protection: low voltage protection, over voltage protection, overheat protection, short-circuit protection, overloads protection

9.CE / EMC / LVD/ RoHS Approvals

10.Two years warranty, life-long technical supports

Function

1.Charging function

There are 2 modes as shown bellow:

2. Utility as complementary power function

There are 2 kinds of complementary modes, shown as bellow:

2.1  AC first , DC standby UPS mode

When both utility and battery are connected to the machine, utility will supply power to the loads prior to the battery. When utility is cut off, the battery will automatically continue to supply power.

Steps are as follows:

Step 1: When utility power is available, it will output directly after voltage being stabilized and charge batteries at the same time.

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

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

See Workflow as below:

2.2 DC first, AC standby UPS mode:

When both utility and battery are connected to the inverter, battery will supply power to the loads prior to utility. When battery capacity is not enough, utility will continue to supply power automatically.

Steps are as follows:

Step 1: When battery has enough power, it will supply power to the loads directly

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

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

See Workflow as below.

3. Timing function

 There are 2 kinds of timing mode:

3.1  Timed on/off normal working mode and sleep mode: can set specific time when to open normal output and when to close AC output to enter sleep mode.

3.2  Battery and utility switchable mode: can set specific time when to use battery or utility supply power (suitable for areas where electric fee is charged according to period in different intervals)

4.  Recording/checking function

4.1 Machine fault checking: can check the machine fault information

4.2 Discharge time checking: can check the discharge time of the battery
