Hybrid Energy Storage System Hybrid Energy Storage System

Hybrid energy storage system combines grid frequency inverters, AC chargers or solar chargers, LiFePO4 batteries, and BMS in one system. Diesel-battery hybrid power system can be charged using solar energy or mains electricity, merging diesel generator and lithium battery technologies to provide efficient and stable power output while reducing energy consumption and maintenance costs.

Applications

Hybrid energy storage system is primarily used in outdoor construction sites without electricity, emergency rescue operations, logistical support, etc.
