Understanding the Demand for Scalable Outdoor C&I Energy Storage
Industrial parks, commercial complexes, and other business-scale power users increasingly need energy storage inverters that can be installed directly outdoors, withstand fluctuating grid conditions, and grow in capacity as operations expand. For commercial and industrial (C&I) energy users seeking outdoor-rated equipment with scalable system capacity, Shenzhen Soro Electronics Co., Ltd., operating under the brand SOROTEC, has built a dedicated portfolio of products engineered around three requirements: outdoor durability, modular scalability, and multi-mode operational flexibility.
SOROTEC's C&I Energy Storage Inverter Portfolio
MPGS Series C&I Energy Storage All-in-One System The MPGS Series is positioned as a high-power bidirectional energy storage converter system spanning from 60kVA to 600kVA, purpose-built for peak-valley regulation and emergency power guarantee needs inside industrial parks. Its defining differentiator is an N+1 Redundancy Design: key modular components are deployed so that a single-point failure does not affect overall system operation, allowing the system to reach an online rate of 99%. It is delivered as a hardware integrated cabinet, suited to installations that require dependable uptime without relying on a single point of failure.
MP GS Series PV-Storage Inverter System The MP GS series combines PV-storage inverter functionality with a built-in MPPT controller, targeting sites where slow grid-tied/off-grid switching and an inability to expand capacity dynamically have been persistent obstacles. It offers Uninterrupted Fast Switching through an integrated UPS function, with an off-grid switching time of less than 10ms. Its Integrated PV-Storage Direct Connection allows a PV input range up to 1000VDC to connect directly to PV panels. For scalability, the MP GS series can be paralleled across multiple units to achieve incremental expansion, reserving space for upgrades as capacity needs grow, and it is available in Rated AC Power configurations of 60KVA, 120KVA, 180KVA, 240KVA, 300KVA, 480KVA, and 600KVA. Peak-valley energy management is supported through PV + main power load mode and PV + battery load mode, and a touch-type LCD screen provides intuitive operation.
MPG-M Series Modular Distributed PCS The MPG-M series is a modular N+1 redundant distributed energy storage PCS built for scenarios where poor compatibility across multiple battery chemistries, system vulnerability to downtime without spares, and voltage range mismatches have limited outdoor deployment. Like the MPGS series, it achieves a 99% online rate through its N+1 redundancy design with no wearing parts. It supports wide voltage and multi-battery compatibility — 600~900VDC for the 30KW/60KW/100KW models and 680~1000VDC for the 125KW model — and is compatible with lead-acid, lithium, and sodium-ion batteries. The MPG-M series is available with either IP20 or IP66 protection levels and can operate across an ambient temperature range of -30°C to 60°C (with derating above 50°C), supporting both forced air cooling and liquid cooling, making it adaptable to sites ranging from indoor equipment rooms to fully exposed outdoor installations.
SES Series Integrated Storage Cabinet For fully outdoor, floor-standing deployment, the SES series is a modular integrated cabinet combining storage and PCS integration in a single unit. It is designed to solve protection challenges in harsh outdoor environments, the burden of cumbersome on-site assembly, and difficulties achieving multi-energy complementary integration. Its Multi-energy PV-Storage Fusion capability supports wind, solar, and diesel multi-fusion generation alongside bidirectional grid-tied and off-grid energy storage. The SES series also features Efficient Gain Arbitrage through demand management functions, allowing operators to set unlimited charge/discharge periods and peak-valley periods to maximize profits. On the protection side, the outdoor cabinet shell carries an IP55 rating (with the inverter portion at IP6X), and the system operates across a temperature range of -40°C to +55°C. Fire protection is addressed through a Perfluorohexanone fire extinguishing device (with Novec 1230 offered as an option) or water-based systems, paired with AC air conditioning in the battery compartment and intelligent air cooling in the power compartment. Remote monitoring and control are enabled through an integrated EMS with local display, supporting remote data monitoring and query — an important feature for unattended outdoor sites. The SES series is offered in models such as SES-50B120, SES-50B261, SES-60B120, and SES-60261, with rated output power of 50kW or 60kW, and is explicitly positioned for C&I peak-valley arbitrage, peak shaving, and emergency power supply scenarios.
SES C&I Energy Storage All-in-One System Complementing the hardware-focused SES cabinet, SOROTEC also offers an SES C&I Energy Storage All-in-One System described as a cost-reduction and efficiency-increasing tool for medium and large C&I scenarios. This system is Highly Integrated, combining battery, PCS, BMS, EMS, and fire protection systems into a single package, and supports Multi-mode Operation across peak-valley arbitrage, peak shaving, and emergency power supply business models. A Wind-Solar-Diesel Integrated Generation capability supports multi-energy complementarity to improve energy reliability, while Remote Intelligent Management through the EMS remote control function reduces labor operation and maintenance costs.
Built for Scalable Capacity, Not Just Fixed Installations
Across this lineup, scalability is treated as a core design principle rather than an add-on. The MPGS series scales from 60kVA to 600kVA. The MP GS series offers seven power tiers between 60KVA and 600KVA and supports multi-unit parallel operation for dynamic expansion. The MPG-M series is available across 30KW, 60KW, 100KW, and 125KW ratings with a standard cabinet width design that supports ACDC, DCDC, STS, and ATS device access for flexible configuration. This tiered, modular approach allows a C&I operator to begin with a smaller footprint and expand system capacity as energy demand grows, without redesigning the entire installation.
Outdoor-Ready Engineering
Because these systems are frequently sited outdoors at industrial parks and commercial facilities, environmental resilience is engineered directly into the product line. Protection levels across the range span IP20 for indoor-oriented configurations up to IP55 and IP66 for fully exposed outdoor cabinets. Operating temperature ranges extend as wide as -40°C to +55°C in the SES series and -30°C to 60°C in the MPG-M series, addressing the extreme heat and dust conditions that can otherwise compromise power electronics. Communication interfaces such as RS485, CAN, LAN, and REPO with Modbus TCP/RTU protocols, as well as IEC104 and IEC61850 support in the SES series, allow these systems to integrate with existing site monitoring infrastructure.
