Frequently Asked Questions
How long can the CQ6 48kWh system provide backup power during a blackout?
The CQ6 can power a commercial building or large home for 12-18 hours during a blackout, depending on load. For essential loads (lighting, HVAC, refrigeration), expect 16-18 hours. For moderate commercial loads (offices, retail), expect 12-14 hours. For heavy industrial loads, expect 8-10 hours. The 48kWh capacity is specifically designed for commercial backup scenarios where extended power is critical.
Is the CQ6 compatible with three-phase power systems?
The CQ6 is a single-phase system designed for commercial buildings with single-phase power infrastructure. However, it can be configured for three-phase applications in commercial settings. If your facility has three-phase power (common in large commercial buildings and industrial facilities), we recommend the Fox ESS EQ4800 42kW three-phase system for superior load balancing. Contact us for a site assessment to determine your power configuration and optimal system.
What is the difference between the CQ6 and EQ4800?
The CQ6 is a 10kW single-phase system with 48kWh capacity, ideal for small businesses, light commercial, and large residential applications. The EQ4800 is a 42kW three-phase industrial system designed for heavy-duty commercial operations, manufacturing facilities, and large estates. The EQ4800 delivers 4x more power output and is optimized for three-phase distribution. Choose CQ6 for light commercial; choose EQ4800 for industrial/heavy commercial needs.
How long can the CQ6 provide backup power?
Backup duration depends on how the system is used. For essential business loads such as lighting, networking, POS systems, and refrigeration, the CQ6 can provide approximately 12–18 hours of backup power. With moderate commercial usage, backup duration may be shorter. For heavy or industrial loads with high continuous demand, a higher-capacity system like the EQ4800 is recommended to ensure longer and more stable backup performance.
Is the CQ6 compatible with three-phase power?
The CQ6 is primarily a single-phase battery system, but it can be configured to work within three-phase commercial environments for balanced load distribution and backup support. This makes it suitable for small businesses and light commercial sites. However, if your property requires true three-phase power for heavy commercial or industrial equipment, the EQ4800 system is recommended, as it is specifically designed for high-capacity, true three-phase applications.
What's the difference between CQ6 and EQ4800?
The CQ6 is designed for light commercial applications and small businesses, offering flexible backup power and serving as a clean alternative to traditional generators. It is ideal for essential and moderate commercial loads. The EQ4800, on the other hand, is built for industrial and heavy commercial environments, delivering higher power capacity and true three-phase performance. For sites with high continuous demand or large industrial equipment, the EQ4800 is the more suitable solution.
