Product Description

Product Description

 

Product Overview

The BNSA series photovoltaic off grid inverters input direct current and output alternating current. Mainly used for solar and wind power generation systems. It has all the advantages of conventional inverters and can also provide absolute reliability for using new energy to generate electricity in mountainous areas, pastures, islands and other areas with inconvenient transportation and harsh environments without electricity.

Product features

1.Low power consumption and high inverter conversion efficiency;

2.Using LCD touch screen to display various operating parameters, relevant parameters can be set;

3.Output a perfectly smooth sine wave, voltage harmonic waveform distortion rate ≤ 1%, stable on load; 

4.Has a slow start function to avoid high current impact on the battery and load;

5.Strong adaptability to the environment, suitable for application in high-altitude, cold, and natural environments.

The photovoltaic off-grid power generation system consists of photovoltaic modules, controllers, batteries, photovoltaic off-grid inverter power supplies, and distribution systems. Solar energy generates electricity through photovoltaic modules, charge and discharge management of the battery through the controller, and provides power to the DC load or provides power to the AC load through the off-grid inverter, This series of BNSA are suitable for places where no public power grid but solar energy resources are sufficient, such as: remote mountainous areas, islands, and plateau areas with harsh environment.
