Product Description

BNSA Series Off Grid Inverter

Power Feature

The BNSA series off grid inverter adopts Sinusoidal Pulse Width Modulation (SPWM) technology. Its main circuit uses Infineon IGBT modules from Germany, while the drive and protection circuit is sourced from Mitsubishi, Japan. It features high reliability, comprehensive protection functions, low waveform distortion and high power output. It is mainly applied in solar and wind new energy power generation systems for off grid areas such as mountainous regions, pastures and islands with inconvenient transportation and harsh environments.

1.Low self consumption and high inverter conversion efficiency.
2.Equipped with an LCD touch screen to display and configure various operating parameters.
3.Delivers perfectly smooth sine wave output with total harmonic distortion ≤1% and stable load bearing performance.
4.Supports reverse discharge protection and reverse polarity protection.
5.Comes with soft start function to prevent high current impact on batteries and loads.
6.Strong environmental adaptability, applicable to high altitude, cold and harsh natural conditions.
