Product Description

UL Inverter 

Introduction:

Sandi off grid UL inverter approved by UL1741 and CSA22.2 standard, popular for US, Canada and worldwide. It can make split phase 120/240VAC or 3 phase 120/208VAC 60hz output or custom made to your specification.It’s suitable for all kinds of AC load. With SVPWM technology it has high conversion efficiency, high instantaneous power and low losses power output pure sine wave, applying to capacitive, inductive and nonlinear mixed-load, with superior load capacity, perfect protection function: overload, short circuit, low/over battery voltage, improper operation etc, which won’t cause mechanical failures.

This Off Grid UL Inverter is very suitable for solar power systems, wind power generation systems, wind and solar hybrid generation systems.

Advantages:

  • Using the sixth generation efficient IPM intelligent module from Japanese Mitsubishi, high efficiency and stable performance. It with 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 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 and under voltage recovery time all can be set via the LCD panel.

  • Using SVPWM space vector algorithms, high conversion efficiency, high instantaneous power and low losses, higher efficiency > 94%.

  • Pure sine wave output. with good transient response less than 50MS, little harmonic distortion, higher conversion efficiency and stable output voltage.

  • Low frequency transformer, which ensure the AC busbar and DC busbar are completely isolated to avoid interference, high efficiency 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 customer’s requirement. Input voltage range can be selected from 100-400v or 200-600v or 400-850v. This wide voltage input off grid inverter can work without battery and solar charge controller, which save battery cost and same like with MPPT function can maximum make full use of solar power .

  • AC bypass input function optional: Battery Power Priority or AC Bypass Priority work mode can be set.

  • RS485 remote monitoring function optional

  • Solar charge controller and AC to DC battery charger built in optional for customer

  • Can be customized to customer’s specification.

  • European CE (EMC and LVD) certification, accredited by Australian CEC, ERAC energy network, meet UL1741 and CSA22.2 standard.
