50KW Three Phase Off Grid Inverter

50KW Three Phase Off Grid Inverter
Product Code : SDP-50KW
Brand Name : Sandi
Product Description

Pure Sine Wave Inverter 50KW three phase Off Grid Inverter with High efficiency for solar energy system

Feature:

  • There are 2 types of start mode: Step down Voltage Start and also has a Variable Frequency Start.
  • The output frequency can be pre determined.
  • The output voltage can be pre set between -40 % to +20 % of already calculated voltage.
  • We can pre set the DC input voltage range. We can also set over voltage point, under voltage point, over voltage revival point, under voltage recovery point.  All these can be set by means of the LCD panel. It is suitable for increasing or decreasing the quantity of batteries, photovoltaic modules also can be utilized lithely.
  • The under voltage recovery time can also be pre set.
  • It has a pure sine wave output.
  • It also has an influential data display and flaws instruction function. The LCD can exhibit DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, produced amount KWH, time and date, temperature, error code display.
  • Using the 5th generation resourceful and competent IPM intelligent unit from Japanese Mitsubishi, with high effectiveness and steady performance. It also comes with dominant safe guard function; the defense for short circuit, over load, over temperature is more secure and consistent. Its working and functional life can span up to 15 years or more.
  • Its extensive input voltage can be placed according to customer's needs. The Input voltage series can be chosen from 100-500 volts, 200 - 850 volts.
  • Output AC Power is appropriate for all kinds of home appliances, LED lamps, electric apparatus, electric motors and many more.
  • High conversion effectiveness, maximum Efficiency is 98%.
  • With Low Frequency Transformer, which make sure that inverter has high effectiveness and lower no load loss.
  • It could add AC bypass input: Battery power precedence or Main power precedence
