Off-Grid Pure Sine Wave Inverter

Our SDP series Off Grid Pure sine wave inverter is one of the most advanced DC

to AC conversion products in the world, it is suitable use for areas without

electricity, vehicles, ships, solar energy, wind turbine and other renewable energy

systems and etc, can supply power and provide guarantee effectively for the areas

with traffic inconveniences, in the mountains, pastoral, border, island and other

areas without electricity. It has the main advantages of high quality sine wave AC

output, microcomputer control, humanness design, and it is high efficiency and low

no-load loss, and no pollution. The inverter can also supply AC power to all kinds of

electric equipment, air conditioners, electric motors, refrigerators, fluorescent lights,

televisions, electric fans and other industrial power supply.

Technical Features:

Using the IPM intelligent Power Module from Mitsubishi, improve the system efficiency

higher

Intelligentized, modularized, simple structure design with powerful function.

Two kinds of start mode: Reduction Voltage Start and Variable Frequency Start. Customers

can set start mode according to the type of their load.

The output frequency 50HZ and 60HZ can be setting via LCD panel.

The output voltage can be set between -40% to +20% of rated voltage.

The DC input voltage range can be set. Over-voltage point, under-voltage point, over-voltage

recovery point, under-voltage recovery point all can be setting via the LCD panel.

Pure sine wave output. With good dynamic response less than 50MS, waveform distortion

rate smaller, higher conversion efficiency and stable output voltage.

Low Frequency Transformer, which ensures that inverter has high efficiency.

Wide input voltage can be set according to customer’s requirement. Input voltage range can

be selected from 100-500V or 200-850V.

AC busbar and DC busbar are completely isolated to avoid interference between AC and DC

High conversion efficiency, Max. Efficiency≥96%

Adopts black pure aluminum radiator, which confirms the best radiating performance.

LCD display, powerful data display and fault instruction function.

European CE (EMC, LVD) Certificate and accredited by Australian CEC, ERAC energy

network.

PV Off-grid Solar power generation system including solar panel array, solar charge controller,

storage battery, Off-grid inverter, etc. In the sunshine, the solar panel convert the solar energy to

DC power and charge the battery group by the charge controller. Then the off grid inverter

convert the DC power into AC power for power supply the AC load.
