20kw Off Grid Inverter

20kw Off Grid Inverter
Product Code : SDP-20KW
Brand Name : SANDI
Product Description

Driven by innovation and technology, our organization is engaged in manufacturing and exporting 20kw Single Phase/Three Phase Off Grid Inverter. Our dexterous manpower uses quality grade materials and components to manufacture this inverter. It is the latest generation of grid connected inverter, fed by solar modules or fuel cells. This inverter combines conservative design topology with proven digital control technology to offer the best performances in any electrical and environmental condition. We offer 20kw Single Phase/Three Phase Off Grid Inverter at reasonable prices to clients.

20kw Single Phase/Three Phase Off Grid Inverter

Feature:

  • 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 and over temperature which is more safe and reliable. Its service life can up to 15-20 years or more.
  • Intelligentized, modularized, simple structure design, convenient for maintenance.
  • Two kinds of start mode: Step Down Voltage Start and Variable Frequency Start.
  • The output frequency 50Hz/60Hz can be set via LCD panel. 
  • The output voltage can be set between -40 % to +20 % of rated voltage. And the accuracy of output voltage is very high less than 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 set via the LCD panel. Convenient for increasing or reducing the quantity of batteries and photovoltaic modules in the future.
  • Pure sine wave output. 
  • Low frequency transformer, which ensures inverter with higher efficiency >94%, and very little no-load loss.
  • Powerful data display and fault instruction 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 customers requirement. Can work without battery, Input voltage range can be selected from 100-500v or 200-850v, inverter can work without battery.
  • High conversion efficiency, Max. Efficiency 96%
  • Could add AC bypass input: Battery Power Priority or AC Bypass Priority optional
  • European CE (EMC and LVD) certification and accredited by Australia CEC, ERAC energy network.
