Product Description

Product Description

 

Product Overview

The BNSX series bidirectional energy storage inverter serves as an electrical interface between the power grid and energy storage devices, with the main function and role of achieving bidirectional energy transfer between AC power grid electricity and energy storage electricity. During discharge, the direct current energy from the energy storage device is converted into sinusoidal alternating current with the same frequency and phase as the power grid and fed into the grid. And during charging, the grid energy is converted into direct current energy and sent to the energy storage device.
 

Product features:
1.0V charging, dedicated to liquid flow batteries;
2.DC soft-start ,Prevent battery from being impacted;
3.It has high and low voltage ride-through ability, fast power regulation, and strong power grid adaptability;
4.Seamless switching between grid connection and off grid / active power adjustable, accept scheduling;
5.Integrated EMS makes it easy to set peak and valley period of time;
6.Equipped with PQ/VF / DC source / black start function;
7.It is suitable for a variety of energy storage application scenarios such as peak load shifting, peak regulation and frequency regulation, and auxiliary new energy grid connection.

Application industry

Applied in scenarios such as assisting new energy grid connection, power frequency regulation and peak shaving, demand side response, microgrids, and users.
