Yilianke (亿兰科) recently closed a multi-million yuan Series A round, with existing investor Timesbole Capital adding to its stake. Proceeds will fund the Zhongshan manufacturing center, expansion of its overseas localized service network, and the rollout and iteration of new products such as AIDC power supplies and SST modules—strengthening delivery, technical response, and after-sales support.
Founded in December 2021, Yilianke is a core power-electronics equipment maker for commercial & industrial (C&I) storage. It focuses on the C&I storage PCS segment and, on a modular architecture, supplies power-electronic equipment and system solutions for C&I storage and microgrids. Headquartered in Shenzhen with a Hangzhou branch, its core team comes from Tsinghua University and leading power-electronics firms such as Emerson and KSTAR, with end-to-end experience in R&D, manufacturing, supply-chain management, and global delivery.
A sector at an inflection point
In 2025, China's C&I storage system shipments reached 24 GWh, up 100% YoY. Global C&I installations are projected to grow ~40% in 2026, with overseas markets exceeding 60%. Yet the logic underpinning the sector's boom is being rewritten.
The biggest variable is China's power-market reform. In 2026, fixed time-of-use (TOU) tariffs move fully to market pricing; the peak-valley arbitrage model that anchored C&I storage economics is loosening as prices become supply-demand driven. Profitability now hinges on creating value across diverse real-world conditions, not policy dividends.
Overseas, use cases are proliferating—from peak shaving to PV self-consumption, transformer capacity expansion, microgrids, and PV-storage-charging integration. The era of one standardized unit fitting all scenarios is over.
Modular architecture as the answer
As early as 2023, Yilianke decoupled the storage system into three standardized power modules—DC/DC, DC/AC, and STS. Customers combine them per project: add STS for off-grid backup, DC/DC for multi-string PV, or a single module for basic peak shaving.
Modularity yields more than hardware flexibility—it builds an evolvable technical backbone. As cells iterate rapidly, the modular architecture lets PCS modules upgrade independently. Yilianke's inter-module coordinated control, honed across many real projects, gives it integrated software-hardware capability.
Market validation shows in shipment rankings: Yilianke ranked 7th in C&I storage PCS in 2023, 4th in 2024, and top 3 in 2025, with products shipped to over 60 countries and regions.
Going global
Since 2024, Yilianke has systematically expanded abroad: overseas end-market share reached 75% in 2025 and rose to 85% in H1 2026.
Overseas environments are far more complex. Many European legacy PV systems use an 800V bus, but most string PCS ship with only 690V AC output, forcing an extra step-up transformer for AC coupling. Yilianke's 215 kW PCS module natively matches 800V PV busbars for direct, transformer-free AC coupling—validated in a 3 MW PV-plus-storage project in India.
In March, Yilianke launched a hybrid inverter series for C&I and microgrids, integrating PV MPPT, bidirectional inversion, on/off-grid switching, and EMS into one "4-in-1" unit. It supports multi-unit paralleling and millisecond on/off-grid switching, adapts to multiple battery types, and meets self-use, feed-in, and backup needs—truly "out-of-the-box." For coastal markets it achieves IP66 protection; for weak-grid regions (Southeast Asia, Africa) its self-developed STS module switches to off-grid in milliseconds, replacing diesel generators. To date it holds 120+ global certifications.
Capacity and service
In October 2025, Yilianke's Shenzhen base completed its second capacity upgrade with a dedicated PCS module workshop, now running at full load. In July 2026, the Zhongshan manufacturing center broke ground—30,000 m², planned at 50,000 PCS modules/year and 2,000 integrated AC cabinets/year. It has spare-parts warehouses in six countries (Europe, Africa, Southeast Asia, Middle East) and will stand up three overseas service centers.
Excerpt from the interview
Bridgetechcn: How does modular PCS solve multi-scenario fit, and what defensible moat does it build versus integrated all-in-one units?
Yilianke: C&I storage sits awkwardly between standardized residential and customized utility storage. Project conditions vary wildly—factory parks, commercial buildings, PV-storage-charging stations, remote mines, island microgrids. Standardized units can't cover fragmented demand; full customizing is too slow and costly. We return to power-electronics fundamentals and decouple the system into three standard modules—a "Lego-style" build that turns non-standard engineering into standard-product combination. The real moat is software: multi-module coordination (power allocation, dynamic response, fault protection) at scale is a systemic problem solved only through continuous real-world iteration.
Bridgetechcn: What will define PCS competition over the next three years?
Yilianke: Specs alone are saturated. The gaps are scenario adaptability, stable operation under complexity, and fast response to new demand. As cells iterate and multi-unit paralleling and off-grid backup grow, whoever solves multi-battery compatibility, seamless on/off-grid switching, and cluster coordination wins. We are deepening modular architecture and control algorithms—three-phase independent control and higher-level coordinated dispatch—and deploying AI-assisted control for impedance adaptive identification, fault prediction, and dynamic power regulation. We are also extending into AIDC compute-storage power and SST modules; power-electronics commonality means we can reach well beyond storage PCS.
