High-power Commercial Energy Storage Battery with 10kWh-100kWh Capacity for Peak-Valley Arbitrage and Emergency Backup

Product Introduction

Designed for small businesses, factories, and office buildings, this C&I storage battery covers 10kWh-100kWh capacities and supports both grid-tied and off-grid operation. Its modular design allows flexible expansion to meet diverse commercial electricity needs .

Core Advantages

• Peak-Valley Arbitrage:​ Automatically adjusts charging during low-tariff periods and discharging during high-tariff periods, reducing electricity costs. With a typical price difference of ¥0.8/kWh, a 10kWh system can save ~¥2,000/year .

• Demand Response:​ Can participate in grid demand response programs, discharging during peak grid load to provide peak-shaving services and generate additional revenue .

• Emergency Backup:​ Automatically switches to off-grid mode during grid outages, providing backup power for critical equipment, ensuring production continuity and minimizing outage losses .

Product Parameters

Application Case

Case: Small Factory Storage Project in Guangdong

A factory in Dongguan, Guangdong, with high electricity consumption and significant peak/off-peak price differences, installed a Liwei C&I storage system (50kWh battery, 30kW inverter). The system charges at night and discharges during daytime peak hours to power production equipment. Over one year, it saved approximately ¥50,000 in electricity costs, with a payback period of about 3 years. The backup power function also prevented production losses during grid outages .

Q&A

Q1: What is the typical ROI period for C&I storage systems?

A: The payback period is typically 3-5 years, depending on the peak/off-peak price difference, electricity consumption, and system capacity. Government subsidies and demand response earnings in some regions can shorten this period .

Q2: How to determine the required capacity?

A: Capacity selection depends on load and tariff differences. Generally, 20%-30% of average daily consumption is recommended. Professional technical consultation is advised for detailed design .

Q3: Are approvals needed for C&I systems?

A: Yes, filing with the local power supply department and grid connection procedures are required. Liwei can provide full technical support to assist with the approval process .
