FAQ
1. Why is this 120kWh system the right choice for commercial energy storage?
This system is engineered specifically for businesses facing high demand charges or seeking backup power for critical operations. Its large capacity allows you to store significant solar energy or low-cost off-peak electricity, providing substantial bill savings through peak shaving and reliable backup during extended outages.
2. What is "peak shaving" and how does this system achieve it?
Peak shaving uses stored battery power to reduce your facility's maximum demand from the grid during high-usage periods. Our system's intelligent controller automatically discharges the battery when it detects a spike in consumption, smoothing out your energy demand and significantly lowering expensive utility demand charges.
3. Can this system be integrated with our existing solar PV array?
Yes, absolutely. This is a DC-coupled or AC-coupled compatible energy storage system. It can be seamlessly integrated with both new and existing commercial solar installations, storing excess solar energy produced during the day for use at night or during grid failures.
4. How long can this system power our critical operations during a blackout?
Backup duration depends on your load. The 120kWh capacity can, for example, power 10kW of critical loads (servers, refrigeration, essential lighting) for over 12 hours. Our team can help you analyze your specific critical load profile for a precise estimate.
5. How is system safety and reliability ensured for a commercial setting?
Safety is paramount. The system features a multi-layered Battery Management System (BMS) with cell-level monitoring, temperature control, and advanced protection against overcharge, short circuit, and overheating. It's housed in a robust, IP-rated industrial enclosure.
6. What support and warranty does Sunrange provide?
We back our commercial systems with a comprehensive 10-year warranty on the LiFePO4 batteries and dedicated technical support. This includes professional system design assistance, installation documentation, and ongoing support to ensure optimal performance throughout the system's life.
