Sail Solar 250kW hybrid solar energy storage system is built for factories and commercial use, with optional 250kWh or 500kWh LiFePO4 battery. It uses smart EMS for peak shaving to cut high peak electricity bills. When the grid works, solar power feeds your factory loads first; extra power charges the battery. If the grid goes down, it automatically switches to backup mode to keep your critical production equipment running.The full package includes solar panels, hybrid inverter, battery cabinet, switchgear and remote monitoring. Available for rooftop or ground mounting, CE/IEC/TUV certified.

How Hybrid Works
Solar panels (PV String) capture sunlight and produce DC electricity. The power goes through the PV Combiner Box for circuit protection and collection, then flows into the **Hybrid Inverter**, the core controller of the whole system.
The hybrid inverter converts DC solar power into usable AC power to supply your factory loads. It manages charging and discharging for the Battery Bank (250kWh / 500kWh LiFePO4 optional).
A SmartLogger collects all real-time operation data. Through the cloud server, you can monitor power output, battery level and system status remotely via PC or mobile APP.

People May Ask
Q1: Can this hybrid system work without battery?
A1: It can run as grid-tied PV without battery, but you will lose peak shaving and power outage backup functions. The battery bank is required for emergency backup and peak shaving.
Q2: Is a diesel generator mandatory for this 250kW hybrid system?
A2: Not mandatory. Generator is optional. It acts as an extra backup for long-duration outages when PV and battery are not enough.
Q3:How long can the battery support my critical loads during a blackout?
A3: Backup duration depends on your critical load power and selected battery capacity. 250kWh or 500kWh battery options are available for different backup time requirements. We can calculate for you based on your load list.
