二、项目痛点与建设目标
工厂用电痛点
1.河南工商业峰谷价差显著：高峰电价为平段1.72倍、低谷仅0.45倍，尖峰时段（冬夏）再上浮20%，日间生产用电集中在高峰/尖峰时段，电费成本高企。
2.光伏出力与用电负荷错配：中午光伏大发（11:00-14:00为春秋季低谷时段），但工厂生产高峰在下午至夜间，光伏余电无法高效利用。
3.用电稳定性需求高：制造产线连续运行，需保障供电可靠，减少电网波动与停电影响。
项目建设目标
1.削峰填谷，电费更优：依托河南分时电价，低谷/光伏大发时段充电，高峰/尖峰时段放电，日均实现“一充一放”或“两充两放”，提升峰谷套利收益。

SmartGen Case | HEMS200 in Xinxiang Pingyuanhu Factory: PV-Storage Synergy Enables Lower Costs and Higher efficiency Smart storage of green Energy（ELPC） empowering green industry; reliable Energy（ELPC） technology safeguarding every kilowatt-hour of clean value I. Project Overview The project is located at a manufacturing factory in Pingyuanhu New Area, Xinxiang, Henan Province. In response to the national “dual carbon” goals, the factory planned to build an integrated “PV + storage” Energy（ELPC） system to optimize its electricity consumption structure and reduce production Energy（ELPC） costs. The total Energy（ELPC） storage capacity is 1.5MWh, complemented by 1.6MWh distributed PV. SmartGen’s self-developed HEMS200 acts as the core brain, enabling PV-storage synergy and Intelligent（IPM） peak load shifting, making this a Benchmark（BHE） industrial and commercial PV-storage integration project in Henan.
Key Project Configuration Energy（ELPC） Storage System: Six 261kWh standardized outdoor liquid-cooled Energy（ELPC） storage cabinets, total capacity 1.5MWh, using high-safety LFP cells, supporting long cycle life and high reliability.
Power Distribution（DSGR） System: One 1-in-6-out smart combiner cabinet, enabling centralized bus connection and grid-tie for the six storage cabinets, with overcurrent protection and surge protection.
Core Control: HEMS200 Hybrid Energy（ELPC） Management System and BMS (self-developed and manufactured), together with the PCS, forming a complete control loop.
II. Customer Pain Points and Construction（ROAD） Goals Factory Power Pain Points
1. Significant peak-valley price difference in Henan’s industrial and commercial sector: Peak electricity price is 1.72 times the flat period, while valley is only 0.45 times; during extreme peak periods (winter/summer) an additional 20% surcharge applies. Daytime production is concentrated in peak/extreme-peak hours, leading to high electricity costs.
2. Mismatch between PV generation and load: At noon (11:00-14:00, valley period in spring/autumn), PV output is high, but the factory’s production peak is in the afternoon and evening, leaving surplus solar power underutilized.
3. High power stability demand: Continuous manufacturing lines require reliable power supply to minimize grid fluctuations and outage impact.
Project Construction Goals
1. Peak load shifting for lower electricity bills: Leveraging Henan’s time-of-use tariff, charging during valley/PV surplus periods and discharging during peak/extreme-peak periods, achieving an average of one cycle or two cycles per day to enhance peakvalley arbitrage returns.
2. Stable, reliable, unattended operation: 7×24h stable operation, fast fault protection, remote diagnosis, reducing on-site O&M costs.
3. Smart control & visible data: Full-dimension monitoring, control, analysis, supporting remote scheduling and Strategy（MSTR） optimization.
III. SmartGen’s Core Advantages
1. Self-developed and manufactured – Independent technology
As a national Specialized and Sophisticated “Little Giant” Enterprise（EFSC） and a high-tech company, SmartGen has independently developed and produced the HEMS200 and the entire storage system, with full control over core technologies.
Nearly 30 years of deep expertise in power control, holding 600+ patents and 60+ software copyrights, covering hardware, embedded algorithms, and Energy（ELPC） dispatch strategies.
R&D team（TEAM） accounts for more than 30% of the workforce; R&D investment in 2025 reached 10.08% of revenue. The EMS has evolved through multiple generations, adapting to all scenarios of industrial and commercial Energy（ELPC） storage.
Industry 4.0 digital workshop + full-scenario test center: Each product undergoes rigorous high/low temperature, EMC, and long-term burn-in tests, ensuring stability on par with top International（IGIC） brands.
2. Long-term stability – High reliability, strong protection, extended operation Precise multi-unit coordination: Through the 1-in-6-out combiner cabinet, the EMS simultaneously manages six storage cabinets, achieving power sharing, SOC balancing, and synchronized charge/discharge. Failure of a single unit does not affect overall operation.
Three-tier fault protection system: EMS + BMS + PCS triple protection; second-level response to 30+ faults (overvoltage, overcurrent, overtemperature, short circuit, leakage, etc（885861）.), actively cutting off risks and ensuring equIPMent safety.
Harsh environment adaptability: Stable operation outdoors from -20°C to 50°C, with anti EMI, dustproof and waterproof (IP54), suitable for Xinxiang’s climate and industrial environment.
Remote O&M + unattended operation: Supports cloud-based remote monitoring, parameter modification, fault diagnosis, and firmware upgrades. No on-site staff required, reducing annual O&M costs by over 70%.
3. Flexible adaptability – Modular design for easy deployment and expansion The EMS uses a modular hardware + open software architecture, quickly adapting to the configuration of six 261kWh cabinets + 1.6MWh PV. The project took only 30 days from site entry to grid connection.
Supports flexible capacity expansion of storage cabinets and compatibility with inverters from different brands, protecting initial investment.
IV. Project Operation Logic Core Operation Strategy（MSTR）: Charge during valley, discharge during peak; PV-storage complementarity; Intelligent（IPM） optimization
1. Valley charging stage
Time periods: 0:00-7:00 (year-round), 11:00-14:00 (spring/autumn).
Logic: During grid valley price (0.45×) and PV surplus hours (spring/autumn), EMS commands the six cabinets to charge at full power. The combiner cabinet distributes power evenly; charging stops automatically when SOC reaches 100%.
2. Flat period optimization stage Time periods: 7:00-11:00, 14:00-16:00 (spring/autumn); 7:00-16:00 (winter/summer).
Logic: PV output is normal; when load fluctuates, the storage makes minor discharge adjustments to stabilize grid-side power and reduce demand charges.
3. Peak/extreme-peak discharge stage Time periods: 16:00-24:00 (peak); winter 17:00-19:00, summer 20:00-23:00 (extreme peak).
Logic: Grid peak price (1.72×), extreme peak adds another 20%; factory production peaks. The EMS controls concentrated discharge of the storage, prioritizing load coverage to reduce grid purchase; during extreme peak, full-power discharge maximizes arbitrage.
V. Project Benefits
1. Economic benefits
Annual peak valley arbitrage: The six cabinets cycle once per day on average, delivering about 460,000 kWh of annual discharge. Based on Henan’s peak-valley spread of RMB 0.9/kWh, annual electricity cost savings are approximately RMB 410,000.
2. Social and environmental benefits Reduces extreme-peak electricity consumption by about 460,000 kWh per year, relieving regional grid peak load.
Equivalent annual CO emission reduction of approximately 790 tons and SO reduction of about 6.5 tons, supporting the factory’s green and low-carbon transition.
In the future, as industrial and commercial Energy（ELPC） storage becomes more widespread and electricity market reforms deepen, SmartGen will continue to provide safe, efficient, and Intelligent（IPM） Energy（ELPC） management solutions based on self-developed technology, industrial-grade quality, and scenario-specific approaches, empowering more Enterprise（EFSC）s and promoting high-quality development of user-side Energy（ELPC） storage.
