Technical FAQs 4

What is a Bess energy storage system?

The modular BESS container design allows accurate capacity-scaled operation for peak shaving and energy arbitrage. The containerized energy storage system incorporates advanced bidirectional inverters that efficiently convert AC power to DC and store it in the battery.

What is a Bess container?

What Is BESS Container? The BESS container refers to an integrated energy storage system contained within standard shipping containers at a scale and speed of deployment. The HJ-ESS-DESL series BESS container with a capacity of 372 - 1860 kWh utilizes advanced liquid-cooling technology to maintain the best temperature for all the battery modules.

How do containerized Bess systems work?

Containerized BESS systems work autonomously to ensure grid stability while promoting integration capacity of renewable energy. The BESS container solutions offer remote monitoring in full, providing real-time performance data and predictive maintenance analytics.

How long does a Bess container last?

Typically, modern BESS containers have a service life of 10-15 years in which time they will have depreciated to less than 80% of their original capacity. This service life largely depends on factors like the frequency of cycling operation, depth of discharge, working temperatures, and maintenance of the system.
