Fuel Savings, Lower Operating Costs
The EMS keeps the diesel engine operating at its optimal efficiency point, avoiding low‑load, high‑consumption conditions. This reduces fuel usage by over 30%, significantly cutting operational expenses.
Enhanced System Performance
The storage system cooperates with the diesel generator – providing peak power support during high demand and absorbing surplus energy during light loads – to maximise overall system efficiency.
High Reliability with Uninterrupted Power
The diesel and storage systems serve as mutual backups. In the event of a fault or during maintenance of either system, the other seamlessly takes over the load, ensuring continuous power to critical equipment.
Noise Reduction for Better Working Conditions
Under light loads, the diesel engine automatically shuts down and the system switches to battery‑only mode, enabling quiet operation. This significantly improves the on‑site working environment and extends the diesel engine’s service life.
