Factory rooftop photovoltaics combined with industrial and commercial energy storage represent a distributed energy solution that leverages unused factory rooftops to install solar arrays paired with lithium iron phosphate energy storage systems. This approach aims to enable industrial and commercial users to achieve self-sufficiency in green electricity, optimize costs, and coordinate with the grid, thereby supporting the industry’s low-carbon transition.

System Components and Operating Principles

1. Roof-mounted Photovoltaic Power Generation System:
   Comprising mono-/polycrystalline PV modules, string inverters, combiner boxes, and corrosion-resistant, wind-resistant mounting structures, this system utilizes factory rooftop space to deploy PV arrays that convert solar energy into direct current (DC). After conversion to alternating current (AC) via inverters, the electricity prioritizes supplying on-site loads, achieving “self-generation for self-consumption.” Surplus energy can be stored in energy storage systems or fed into the grid at market-based rates.
   
2. Commercial & Industrial Energy Storage System:
   Features integrated lithium iron phosphate storage cabinets incorporating Battery Management Systems (BMS), Power Conversion Systems (PCS), and liquid-cooled temperature control units. Charges from the grid during off-peak hours, stores surplus solar power, and discharges during peak demand periods, insufficient solar output, or high-cost electricity periods to replace expensive grid power.
   
3. Photovoltaic-Storage Synergy Management System:
   Based on an AI Energy Management System (EMS), it connects PV, storage, and load equipment via multi-protocol compatibility technology. Achieves PV output forecasting with over 95% accuracy and dynamically adjusts charging/discharging strategies. Supports peak-valley arbitrage and demand control modes, responding to load fluctuations and electricity price changes within minutes.
   
4. Auxiliary Protection System:
   Equipped with aerosol + perfluorohexane fire suppression systems and IP55-rated cabinets. Combined with fire-resistant cable routing and reinforced bracket structures, it adapts to complex rooftop operating environments, ensuring system safety and stability.
