BESS 500 Battery Energy Storage System

In areas completely devoid of grid coverage—such as mining camps deep in the mountains, oil exploration sites in the desert, or newly constructed highway sections—the only viable options for securing stable, continuous power supply are typically two: deploying diesel generators or investing substantial costs to install power grids from dozens of kilometers away. Many have experienced the challenges of diesel generators: fuel transportation trips can take an entire day, the noise is so intense that sleep is impossible at night, and any machine failure halts the entire construction site.

Greenwatt BESS 500 Battery energy storage system with a maximum power output of 500 kW within a metal cabinet measuring 3000×2200×2300 mm—approximately the size of a standard small container that can be transported by conventional flatbed trucks without requiring specialized clearance vehicles. More importantly, the cabinet contains not conventional lithium-ion batteries but semi-solid-state batteries. The electrolyte in these batteries lies between that of liquid and all-solid-state batteries; compared to traditional liquid lithium batteries, they exhibit higher thermal stability, are less prone to catching fire when punctured or compressed, and demonstrate significantly longer cycle life—measured to exceed 6,000 cycles, equivalent to stable operation for 15–16 years under daily charge-discharge cycles.

Highly integrated system architecture: The battery cluster, high-voltage cabinet, PCS, BMS, and fire protection module are pre-wired and debugged upon factory delivery. On-site installation only requires connecting the load cable and photovoltaic input lines, enabling immediate operation upon power supply. With an IP54 protection rating, the system requires no additional outdoor shelters and functions reliably across temperatures from-10°C to 50°C.
