GRES 200-600kw


GRES refers to a set of an integrated systems combining hybrid inverter with energy storage battery, the grid, diesel generators, photovoltaic, wind energy, load, etc. The microgrid system can realize the reasonable configuration and scientific utilization of new energy generation, energy storage battery, and power grid, and provide users with high power quality, high reliability, and high security power service.


1. Uninterruptible power supply;
The system can be operated off-grid. When the power supply of the power grid is interrupted, the back-end load can be continuously powered by the battery independently, and the switching time is less than 10ms. After the power grid is restored, it can automatically switch to the on-grid mode, completely replacing ups and EPS;

2. Peak shaving, max power load reducing
For the enterprises with intermittent power consumption and large fluctuation of power load curve, GRES system can reduce the load during peak period, reduce the peak power consumption, reduce the power supply pressure of the grid, and use the peak valley price difference to generate income for the enterprises.

3. Improving power quality
GRES system is connected in parallel on the grid side, which can generate active power or make reactive power compensation, compensate the harmonic, power factor and three-phase imbalance of load, realize power quality management, save the user’s investment in reactive power compensation equipment, reduce line loss and interference, and improve the utilization rate and efficiency of transformer.

4. Multi energy complementation
Through the access of new energy power generation equipment such as photovoltaic and wind turbine, basic power supply guarantee is provided for remote areas such as isolated islands and mountainous areas that lack power grid facilities. Use battery energy storage system to store surplus power, smooth the fluctuation of new energy power, and improve the energy utilization rate of the system.
