C&l PV & Energy
Cut electricity costs, stabilize operations, and maximize on-site solar — with integrated outdoor storage cabinets built for factories, parks, and commercial facilities.
Our C&I PV + storage platform combines liquid-cooled ESS cabinets, PCS, and intelligent EMS to support peak shaving, demand management, PV self-consumption, and backup power for critical loads.
From project assessment and system matching to equipment supply and commissioning support, we help industrial and commercial operators turn energy from a cost center into a controllable asset.
Solution Overview
Smarter Energy for Business Operations
Commercial and industrial sites often face rising tariffs, demand charges, and unstable supply. Our C&I PV + storage solution couples rooftop or ground-mounted PV with liquid-cooled outdoor ESS cabinets, PCS, and intelligent EMS.
The system is designed for peak shaving, valley filling, PV self-consumption, backup power, and microgrid scenarios — helping factories, warehouses, shopping centers, and industrial parks turn energy from a cost center into a controllable asset.
Key Benefits
Lower Cost. Higher Resilience.
Practical outcomes for operators who need measurable savings and reliable power quality day after day.
Peak Shaving & Demand Control
Discharge during peak tariff windows and reduce maximum demand charges to improve monthly electricity economics.
Higher PV Self-Consumption
Store surplus midday solar and shift it to evening loads, increasing the value of every kilowatt-hour generated on site.
Backup for Critical Loads
Keep production lines, servers, cold storage, and security systems running during grid disturbances or outages.
Modular & Scalable Deployment
Start with a right-sized cabinet configuration and expand capacity as load growth or additional PV is added.
System Architecture
Integrated Outdoor Storage Platform
Our C&I solution centers on high-safety LFP battery cabinets with liquid cooling, coordinated BMS/PCS/EMS control, and multi-level protection — ready for outdoor installation with a compact footprint.
- All-in-one or modular cabinet architectures
- Precise thermal management for longer cycle life
- EMS strategies for tariff, PV, and backup modes
- Compatible with mainstream inverters and PV arrays
Applications
Built for Real Business Sites
Tailored configurations for different load profiles, operating hours, and ROI targets across commercial and industrial environments.
Factories & Workshops
Stabilize production power, reduce peak demand, and protect equipment from voltage fluctuations.
Industrial Parks
Shared or distributed storage assets that support multi-tenant facilities and campus-level PV systems.
Commercial Buildings
Optimize HVAC and lighting loads while improving green building performance and energy transparency.
EV Charging Hubs
Buffer charging peaks, reduce grid reinforcement costs, and pair with rooftop solar for cleaner charging.
Warehouses & Logistics
Support cold-chain reliability and round-the-clock operations with PV-plus-storage backup strategies.
Microgrids
Enable islanding capability and multi-source coordination for sites with weak or unstable grid access.
Delivery Model
From Assessment to Continuous Support
Yiwei supports C&I clients as a system partner — not only a product supplier. We help match equipment to tariff structures, load curves, and local grid conditions.
- Load & tariff analysis before design
- PV + ESS capacity matching and ROI modelling
- Installation guidance and commissioning support
- Training, remote diagnostics, and after-sales service
