What happened

Chinese solar and energy storage manufacturer Hoymiles has unveiled a new commercial and industrial (C&I) energy storage system with capacities starting at 2 MWh, higher than those typically offered in the segment.S1

The new HoyUltra 2,000M is available in 15 configurations, with storage capacities ranging from 2 MWh to 2.61 MWh.S1 Rated AC output spans 500 kW to 1.25 MW, with configurations supporting AC voltages of 380/400 V, 690 V, and 800 V.S1 The system uses 314 Ah lithium iron phosphate (LFP) cells from an undisclosed supplier.S1

The cabinet integrates batteries, a power conversion system (PCS), thermal management, a static transfer switch (STS), and fire protection equipment.S1 The STS switches to backup power in less than 20 ms to maintain an uninterrupted power supply.S1 Liquid cooling is applied to both the PCS and the battery, with an operating temperature range of -30 C to 55 C, and the system maintains rated power up to 50 C.S1 A cabinet-level fire protection package covers smoke and temperature detection, fire suppression, interlocked ventilation, and an explosion pressure relief device.S1

All configurations measure 6,058 mm x 2,591 mm x 2,438 mm and weigh between 22,700 kg and 26,000 kg.S1 The containerized systems carry an IP55 ingress protection rating, C5 corrosion resistance, and can operate at altitudes of up to 2,000 meters.S1 Quoted comment from Rex Zhu, general manager of Hoymiles' Residential and C&I Energy Storage Business: "customers need solutions that go beyond storage capacity"[S1]. The source did not disclose pricing, regional availability, certification marks, or the LFP cell vendor.

XAIPART take

Technical impact

The HoyUltra 2,000M expands Hoymiles' C&I lineup into a multi-megawatt single-cabinet class that most rivals still split across several enclosures. The 314 Ah LFP format points to second-generation large-format prismatic cells, the same format CATL and EVE have been pushing into grid-scale ESS since 2023, while the undisclosed supplier creates a BOM visibility gap that procurement teams should close before qualification. Liquid cooling on the PCS as well as the battery, the -30 C to 55 C envelope, and the <20 ms STS make the cabinet suitable for sites that need ride-through alongside storage, such as manufacturing lines with sensitive PLC loads. XAIPART analysis.

Market impact

Offering 15 SKUs across three AC voltages in one container is a deliberate play to compress integrator configuration effort, which usually translates to shorter RFQ cycles for EPCs working on factories, data centers, and remote microgrids. With Chinese vendors competing on $/kWh in C&I, the disclosure of a 20 ms STS, IP55, and C5 corrosion gives Hoymiles a defense against comparisons with Huawei LUNA2000 and Sungrow ST2752UX on backup and harsh-environment readiness. Pricing, certification marks (UL 9540, IEC 62619, CEI-016), and delivery lead time are still missing from the release, which keeps the procurement case open for distributors weighing Hoymiles against incumbents. XAIPART analysis.

Action

Buyers evaluating the HoyUltra 2,000M should request the full datasheet to confirm UL 9540 or IEC 62619 listing status, regional service coverage, and a bill of materials that names the 314 Ah LFP cell vendor. Engineering teams should validate site electrical interfaces against the three supported AC voltages (380/400 V, 690 V, and 800 V) and confirm transformer ratios before locking the cabinet into an EPC design. Hold price requests until a formal quote is issued and confirm STS ride-through performance with a factory witness test before signing the PO. XAIPART analysis.

XAIPART Forecast

If Hoymiles does not publish a UL 9540 or IEC 62619 certification reference and named cell vendor for the HoyUltra 2,000M by Q2 2027, XAIPART expects Western C&I EPCs will continue to default to incumbent brands and Hoymiles' share of new European and North American C&I orders in this 2-2.61 MWh class will remain below 10% of awarded volume during 2027.
