A : Savings depend on your electricity consumption, local peak/off-peak price differentials, and system capacity. For a 215kWh system with one charge-discharge cycle per day, assuming a price differential of $0.10/kWh, a single cycle can save approximately $21.50. Actual returns vary by local utility rates and load profiles. We can provide a customized ROI analysis for your business.

A : Capacity selection is based on two key factors: peak load power (determines PCS rating) and energy shifting demand (determines battery capacity). Typically, we analyze your past 12 months of utility bills to calculate maximum demand and off-peak charging needs. We recommend leaving about 20% capacity margin for future load growth.

A : The payback period for C&I energy storage projects is typically 3–6 years, depending on local peak/off-peak price differentials, system costs, government incentives, and your company's self-consumption capability. With declining battery costs and ongoing power market reforms, payback periods continue to shorten.

A : Here's a quick comparison:
Liquid-cooled series: Provides precise thermal control with temperature differences maintained within < 3°C, significantly extending battery cycle life and improving efficiency in high-temperature environments. Ideal for high-density, high-power projects.
Air-cooled series: Mature technology with lower upfront investment and simpler maintenance. Suitable for small to medium-sized projects or cost-sensitive applications.

A : The main differences are capacity and physical footprint. Larger capacity generally means greater floor space and weight, and can cover higher electricity demand. The choice depends on your available installation space and actual consumption needs.

A : These refer to the DC-side voltage level of the energy storage system. A 1500V system, compared to 1000V, operates at lower current for the same power output, allowing for thinner cables, reduced line losses, improved system efficiency, and lower equipment costs. 1500V is currently the mainstream trend for large-scale C&I and utility projects.

A : A complete C&I energy storage system typically includes: PCS (Power Conversion System) , Battery cabinet/racks, BMS (Battery Management System) , EMS (Energy Management System) , and HVAC, fire suppression, and safety systems. The system can be flexibly configured based on project size and application needs.

A : Yes. Whether through AC-coupled or DC-coupled architecture, we can match the ESS with your existing PV system. Our hybrid inverter series is specifically optimized for PV + storage integration, enabling intelligent coordination among solar, storage, grid, and loads.
