Diesel-battery hybrid power system by operating in a complementary way
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.
Features
- Diesel-battery hybrid power system is equipped with a 32kWh lithium battery that can be pre-charged to save fuel, a 20kW AC/DC charger, a 50kW grid frequency inverter, and a 600W industrial air conditioning system.
- An outdoor protection rating of IP45 provides excellent waterproof and dustproof performance.
- Wide operating temperature range: -20 to 45 ℃.
- Simultaneous charging and discharging of the battery and load are supported.
