Product Description

40kW single-phase off grid power inverter for solar power system

Sandi pure sine wave series inverter is one of the most advanced DC to AC conversion products in the world, it has the main advantages of high quality sine wave AC output, microcomputer control, humanness design, and it is simple, stable, no noise and no pollution. It is suitable use for areas without electricity, vehicles, ships, solar energy, wind turbine etc. The inverter can also supply AC voltage to all kinds of power tools, air conditioners, electric motors, refrigerators, fluorescent lights, televisions, electric fans and other power supply.

The inverter output waveform is pure sine wave; this kind of AC power is suitable for most industrial electronics and home appliances, the power supply features much better than other modified sine wave and square wave.

 

 

Technical Features:

  • Using the fifth generation efficient IPM intelligent module from Japanese Mitsubishi, high efficiency and stable performance. It with powerful protection function, the protection for short circuit, over load, over temperature is more safe and reliable. It’s service life can up to 15 years or more.
  • Intelligentized, modularized, simple structure design easy to maintenance.
  • Two kinds of start mode: Reduction Voltage Start and Variable Frequency Start. Customers can set start mode according to the type of their load. This function is very convenient for users and also reduce frequency converter’s usage, which reduced the cost of equipment investment, easy to connect wires and control.
  • The output frequency can be setting via LCD panel, it’s very convenient for customer.
  • The output voltage can be set between -40 % to +20 % of rated voltage. And the output voltage is very accuracy ±1%.
  • 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 ensure the DC busbar and AC busbar are completely isolated to avoid interference.
  • Wide input voltage can be set according to customer’s requirement. Input voltage range can be selected from 100-500V or 200-850V.
  • High conversion efficiency, Max. Efficiency≥96%
  • Adopts black pure aluminum radiator, which confirms the best radiating performance.
  • Powerful data display function. LCD can display the DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, output power KWH, time and date, temperature, fault code display.
  • Wide input voltage can be set according to customer’s requirement. Input voltage range can be selected from 100-500V or 200-850V.
  • European CE (EMC, LVD) certificate, accredited by Australian CEC, ERAC energy network.

[Optional]

  • RS485 remote monitoring;
  • Can addAC bypass complementary function;
