# Energy Storage Solutions for Small and Medium-Sized Factories Build factory-level PV-storage microgrids and demand management with core solutions such as SP250HAG2T / SP500HCG2. Solution Overview For small and medium-sized manufacturing enterprises, we provide standardized, phaseable PV-storage microgrid and demand management solutions for small and medium-sized factories. Key Points Factory-level PV-storage microgrid and demand management Flexible configuration of the SP series by capacity Demand management reduces basic electricity charges Phaseable, rolling investment based on returns Applicable Scenarios and Challenges High electricity costs as a proportion of total costs and large demand fluctuations; grid fluctuations can easily cause equipment downtime and defective products; limited budgets require rapid returns. VGRID System Composition **Power Conversion System (PCS)**: Models such as SP250HAG2T / SP500HCG2 support power conversion for small and medium-capacity factories. **Static Transfer Switch (STS)**: Protection and switching at the grid connection point. **Battery Energy Storage System (BESS)**: Peak shaving and valley filling, plus short-term backup power. **Energy Management System (EMS)**: Demand forecasting and strategy optimization to reduce basic electricity charges. **Microgrid AC Cabinet (MPS)**: Factory-level AC cabinet with integrated metering. Core Value Reduction in both energy charges and demand charges More stable power supply, reducing downtime and defective products Standardized solution with fast delivery and clear returns Phaseable capacity expansion in line with production capacity Typical Applications Suitable for small and medium-sized manufacturing factories such as injection molding, hardware, food, and textiles. Delivery and Support VGID POWER (VGRID) provides integrated delivery from on-site assessment, system design, and core equipment manufacturing (PCS/STS/BESS/MPS) to commissioning and remote O&M.

A phased approach can be adopted: start with demand management, then expand with PV and energy storage, and invest on a rolling basis according to returns. ## Can standard models meet customization needs? The SP series covers common small and medium capacities, and MPS/EMS can be configured according to process requirements and transformer capacity. ## Roughly how much load can one system cover? Configured according to transformer capacity, commonly at the several-hundred-kW level, covering the peak and off-peak periods of the main production line. ## Which loads can the KMU protect during a power outage? The EMS prioritizes critical process and security loads, while non-critical loads can be shed.
