Weak Power Grids

The weak grid energy storage solution is a power supply system solution that integrates photovoltaic power generation, diesel power generation, and energy storage, designed for scenarios where power consumption is difficult. With the integrated liquid-cooled energy storage cabinet as the core, this solution can flexibly configure the number of energy storage cabinets according to the actual scenario requirements, thus achieving energy storage with different capacities.

The system supports the access of multiple energy sources such as the power grid, photovoltaic power generation, and diesel generators, and is equipped with corresponding functional modules to form an integrated photovoltaic-diesel generator energy storage system.At the same time, it can also be equipped with an STS functional module to achieve automatic grid-connected and off-grid switching with the power grid, ensuring stable power supply in areas with weak power grids.
