Solreach High-Capacity Battery Module · XH-S Series 64 KWH

Q1: What makes the XH-S Series 64KWh different from the Solreach 16KWh residential battery module?

The XH-S is a commercial-grade, cabinet-format module with 4× the capacity (64KWh vs 16KWh), active thermal management, a four-protocol industrial communication stack (RS485/RS232/USB/Dry Contact), and a modular architecture designed for MWh-scale multi-cabinet arrays. The 16KWh residential module uses a wheel-type enclosure, passive cooling, and 485-CAN communication — suited for single-home or small commercial use. The XH-S targets C&I, microgrid, and utility-edge projects where capacity, integration, and thermal reliability are the primary selection criteria.

​

Q2: How does active thermal management work and why does it matter at 64KWh capacity?

At 64KWh and 200A continuous current, heat generation within the cell stack is significant — passive convection alone cannot maintain cells within their safe temperature window during sustained high-rate charge or discharge events. The XH-S integrates an active cooling circuit directly into the cabinet, circulating conditioned air or coolant (depending on configuration) across the cell modules. This keeps cell temperatures stable regardless of ambient conditions, preventing accelerated capacity fade from thermal stress and enabling the full 200A/200A current rating to be sustained without derating — even in installations at 4000m altitude or in tropical climates above 40°C.

​

Q3: How many XH-S cabinets are needed to build a 1MWh BESS, and what does the system footprint look like?

With 57.6KWh usable per cabinet, 18 XH-S units provide approximately 1.04MWh of usable storage. Each cabinet measures 613×1040×1352mm — a 0.638m² floor footprint. An 18-cabinet 1MWh array in a 2×9 row layout occupies approximately 23m² of floor space (including 800mm service aisles), making it feasible for standard C&I plant rooms, containerised BESS enclosures, or covered outdoor pad installations. Total system capacity can be configured to any MWh target by adding cabinets and adjusting the inverter/PCS rating accordingly.

​

Q4: Which inverter and EMS brands is the XH-S Series compatible with?

The XH-S communicates via RS485 Modbus RTU, RS232, USB, and Dry Contact — the four protocols that collectively cover the BMS communication requirements of virtually all commercial inverter and EMS brands, including SMA, ABB, Schneider Electric, Sungrow C&I series, Huawei FusionSolar, Victron Quattro, Deye commercial, and most SCADA platforms using IEC 61850 or BACnet gateways. Dry Contact enables direct AMF signalling to diesel generators. Buyers should confirm their specific inverter model's supported BMS protocol with Solreach prior to ordering.

​

Q5: What is the rated cycle life and expected calendar lifespan of the XH-S LiFePO₄ cells?

Grade-A Gotion LiFePO₄ cells used in the XH-S Series are rated for over 6,000 cycles at 0.5C and 25°C to 80% residual capacity. At one full cycle per day, this equates to more than 16 years of calendar life — making the XH-S financially viable for C&I projects requiring a 10–15 year ROI horizon without battery replacement. Active thermal management extends effective cycle life beyond the rated figure by maintaining cells within the 20–30°C optimal temperature band during operation, reducing Arrhenius-rate degradation that shortens lifespan in passively-cooled systems.

​

Q6: Can the XH-S Series be deployed outdoors, and what environmental ratings apply?

The XH-S carries an IP54 enclosure rating — dust-protected and splash-resistant — suitable for covered outdoor installations such as canopied pad mounts, containerised BESS, and plant-room installations with open louvres. It is not rated for direct rainfall exposure without an outer weatherproof enclosure. Operating temperature is −10°C to +60°C; storage temperature is −15°C to +60°C. Maximum operating altitude is 4000m with derating above 1000m. For fully exposed outdoor deployment, Solreach recommends pairing XH-S cabinets with an outdoor-rated steel or GRP enclosure rated to IP55 or higher.

​

Q7: What are the logistics specifications for the XH-S 64KWh cabinet and how should OEM buyers plan import shipments?

Cabinet dimensions: 613×1040×1352mm (L×W×H). At approximately 300–350kg estimated gross weight per cabinet (confirm with Solreach for exact shipping weight), a 20-foot container accommodates approximately 12–15 units depending on palletisation configuration. Each unit ships as a lithium battery assembly under UN 38.3 / IATA PI 965 Class 9 dangerous goods regulations. Solreach provides MSDS, UN 38.3 test summary, packing declaration, and cell certification documentation as standard for all export orders. OEM buyers ordering 10+ units can request a consolidated export documentation package for customs clearance in destination markets.
