Questions fréquemment posées

A C&I (Commercial & Industrial) ESS is a high-voltage integrated energy solution specifically engineered for businesses. Unlike small residential lithium batteries, it combines Grade A+ LiFePO4 battery strings, an intelligent BMS/EMS, and a high-power PCS. It is designed to handle heavy industrial loads, stabilize the grid, and deliver massive cost savings through peak shaving and load shifting.

It refers to battery systems paired with commercial solar panels. By storing excess solar energy generated during the day, businesses can power their operations at night or during peak-tariff hours, maximizing solar self-consumption.

Focus on three pillars: Safety (look for LiFePO4 chemistry and fire suppression), Cycle Life (≥ 6000 cycles), and Scalability. Ensure the system voltage (High Voltage) and discharge rate (0.5C/1C) match your heavy machinery requirements.

This depends on your daily energy consumption and peak load. Typically, we analyze your utility bills to determine the optimal size—ranging from 30kWh for small offices to MWh+ for large industrial plants.

Yes. Our systems are designed with high compatibility. They work seamlessly with leading global inverter brands such as Victron, SMA, Growatt, Deye, and Solis via CAN/RS485 communication.

While both focus on cost-saving, Commercial systems (for offices/retail) are often modular and indoor-friendly (like our Stackable series). Industrial systems (for factories/mining) require higher capacity, IP54-rated outdoor durability, and advanced safety features like automated fire suppression to handle harsher environments and larger power surges.
