Microgrid Solution

Our microgrid solutions combine on-site power generation, energy storage, and on-site energy consumption in order to increase reliability and improve energy balance in smart grids.

Microgrid is a self-contained distributed energy system that can generate its own power onsite and use it when most needed.

It can be operated when connected to the utility grid or in a separate “island” mode. If the grid fails or the electricity bill peaks, the microgrid can serve immediately.

Hybrid Power Solution

With the hybrid power solution, electric cars can now run even greener. By using the weather-generated electricity, storing it in the ESS and topping up any EV with clean energy.

Similar to traditional on-grid energy storage systems, this unit can provide grid balancing services in addition to being able to provide more power to the vehicle than the grid can provide during peak hours.

An Off-grid Electric Vehicle Charging Station Solution with Clean Energy Power Supply to German Customers

Our German customer wants to install a DC fast EV charger in his factory, but there is no grid power supply. For this reason, we provide the customer with an off-grid EV charging station solution, that is, using a mobility energy storage system to power the charging piles. The energy storage system stores electrical energy in the photovoltaic power station and then goes to the charging station to release the stored energy to the charging pile to provide power for electric vehicles. This innovative move enables charging piles to be powered independently, no longer dependent on the power grid while ensuring the continuity of charging services.
