A: This air-cooled C&I energy storage system is suitable for commercial buildings, small factories, farms, light industrial facilities, distributed PV + storage projects, backup power systems and small-scale industrial microgrids. It is designed for projects that require reliable energy storage, peak shaving, load shifting and improved solar self-consumption.
A: This product is available in two configurations: 50kW/112kWh and 125kW/241kWh. The 50kW/112kWh model is suitable for smaller commercial and light industrial applications, while the 125kW/241kWh model is better for projects with higher energy demand and longer backup time requirements.
A: The system uses LFP battery technology, which is widely used in commercial and industrial energy storage because of its high safety, long cycle life, stable performance and good thermal stability.
A: This product uses intelligent air cooling. The air-cooled design helps control system temperature during operation and is suitable for standard commercial and industrial applications with moderate power demand and normal operating environments.
A: Air-cooled ESS is generally simpler, more cost-effective and easier to maintain, making it suitable for small to medium C&I projects. Liquid-cooled ESS provides more precise temperature control and is more suitable for high-temperature, high-cycle and heavy-duty industrial applications.
A: Yes. This all-in-one C&I ESS can be used in PV + storage projects to store excess solar energy, improve self-consumption, reduce electricity costs and provide backup power when the grid is unstable.
A: Yes. The system can charge during low-tariff periods or when solar generation is available, and discharge during peak demand periods. This helps reduce demand charges, optimize energy usage and improve overall energy cost savings.
A: Yes, depending on project design. The system can be used in weak-grid areas, microgrids or hybrid energy projects together with solar PV, diesel generators and grid power. For fully off-grid applications, system configuration should be evaluated according to load demand, backup time and site conditions.
A: Yes. The system supports flexible capacity expansion according to project requirements. Multiple units can be configured in parallel for larger commercial or industrial energy storage applications.
A: To recommend the right configuration, please provide your project location, application scenario, daily load profile, peak power demand, required backup time, grid condition, solar PV capacity if available, installation environment and whether the project requires on-grid, off-grid or hybrid operation.
A: Yes. HMZ Technology supports OEM and ODM cooperation for energy storage products, including branding, appearance design, system configuration and project-based customization according to customer requirements.
