Full Power 12000 Watt Pure Sine Wave AC Inverter For Off Grid Power System

      The 12kw pure sine wave AC inverter is one of the most advanced DC to AC converter in the world. We choose high quality materials (Mitsubishi sixth IPM power module, Schneider control, etc.) to ensure it with high efficiency and stable performance. This inverter adopts three-phase&four-wire technology which provide single-phase, split-phase and three phase AC power out, also with two starting models and full power output, so it can work for all kinds of load, such as air conditioners, electric motors, refrigerators, fluorescent lights, televisions, electric fans and other industrial power supply. It has pure sine waveform output, and more than 94% conversion efficiency. This kind inverter can be work with battery, solar panel or Wind generator directly. It’s widely used for solar energy, wind energy and other renewable energy system which usually install at mountains, pastoral, border, island, vehicles, ships and other areas where doens't have grid power or just want independet power system.

 

Advantages

  • Save cost: it can work with solar panel directly, without battery and solar charge controller, the inverter makes the whole system more economical
  • Voltage stabilizing: the inverter has high precision voltage stablizing and filtering, when utility grid power is unstable or poor, the inverter can give out stable voltage and high quality pure sine waveform, the voltage transient response is less than 40ms
  • 0 second seamlessly switch between DC power and grid power: when solar power or battery power is poor, inverter will automatically swith to grid power immediatly. The switch time is 0 seconds
  • Unique anti-oscillation function: when there is no grid power input, the inverter still can running stably and independently. It won't happen to turn on/off repeatedly these oscillation problems
  • High efficiency: if it work with solar panel direcly, with the maximum power point tracking function, the using efficiency of solar power/wind power can be up to 94%
  • Durable&Long service life: anti-sand, resistant to moisture and salt, suitable for harsh environment, the designing service life more than 15 years

Features

  • It adopts the sixth generation efficient IPM intelligent module from Japanese Mitsubishi. This makes the inverter high efficiency and stable performance. It also has powerful protection function for short circuit, over load and over temperature which is more safe and reliable. It's service life can up to 15~20 years or more
  • Intelligentized, modularized and simple structure design, very easy and convenient for install and maintenance.
  • Two kinds of starting models: The Step Down Voltage Start model is suitable for any resistive loads, such as lamp, resistance, computer and so on. The Variable Frequency Start model is suitable for any inductive loads, such as pump, motor, welder and so on. Customers can choose the starting model 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 inverters adopts SVPWM space vector algorithms, high conversion efficiency, high instantaneous power and low losses conversion efficiency up to 94%.
  • The LCD display DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, output power, time&date, temperature, fault code and so on.
  • Users can set over voltage, under voltage, over voltage recovery point, under voltage recovery point, DC input voltage range, output frequency, output voltage range.
  • Pure sine wave output with good transient response less than 40MS, little harmonic distortion, higher conversion efficiency and stable output voltage.
  • The inverter uses black pure aluminum radiator and high quality fans which could continuously work for 5 years and uninterrupted work for 20 years.
  • European CE (EMC and LVD) certification and accredited by Australia CEC, ERAC energy network.
