Outdoor Integrated Solar-Storage-Diesel Cabinet | 50kW/109kWh
This system features an all-in-one smart design, integrating solar PV, battery storage, and diesel generator hybrid power supply, suitable for off-grid, grid-tied, and hybrid applications. Equipped with a high-efficiency hybrid inverter, it supports multi-source input (diesel generator, PV, and grid power), intelligently optimizing energy dispatch to maximize renewable energy utilization and reduce diesel dependency.
Key Advantages:
✔ Seamless Switching – In case of grid failure, automatic backup power (PV/storage/diesel)切换 within 0.02 seconds, ensuring critical load continuity for high-reliability scenarios.
✔ Hybrid Energy – Solar-first power supply, battery storage for peak shaving, and diesel backup guarantee 24/7 uninterrupted operation.
✔ Smart Management – Built-in Energy Management System (EMS) enables remote monitoring, load optimization, and fault alerts for enhanced O&M efficiency.
✔ High Scalability – Modular design allows flexible expansion of storage capacity and PV power to meet diverse energy demands.
Typical Applications:
Telecom base stations & remote area electrification
Emergency power & medical facility backup
Commercial/industrial microgrids & off-grid residential supply
