Key takeaways

  • Pylontech’s revenue fell 39 % to CNY 2.0 billion, driven by both a 19 % volume decline and severe per-kWh price erosion. Implied ASP dropped to roughly CNY 1,287/kWh.
  • Net profit collapsed 92 % to CNY 41.1 million, with the company posting a net loss when excluding non-recurring items.
  • The company remains an almost pure-play ESS business — energy storage accounted for 97.6 % of total revenue.
  • Overseas markets delivered 93.8 % of revenue with a 30.33 % gross margin, while the domestic business ran at just 2.67 % margin — a staggering gap.
  • New products including the Force-H3X, Elva residential system, M7 liquid-cooled C&I system, and a sodium-ion home storage unit signal a push beyond Pylontech’s traditional residential LFP stronghold.

1. Headline numbers

Pylontech reported total revenue of CNY 2.005 billion for the year ended December 31, 2024, down 39.24 % from CNY 3.300 billion in 2023. Net profit attributable to shareholders was CNY 41.1 million, a 92.03 % decline from the prior year. Excluding non-recurring gains, the company posted a net loss — meaning operating profitability effectively disappeared.

ESS segment gross margin came in at 28.90 %, down 1.54 percentage points year-on-year, while company-wide gross margin was 28.94 %, down 2.00 percentage points. While not catastrophic in isolation, the margin decline combined with the revenue collapse left insufficient gross profit to cover the company’s operating expenses. R&D spending alone consumed CNY 345.1 million, or 17.22 % of revenue — an unusually high ratio that reflects both Pylontech’s investment posture and the denominator effect of shrinking revenue.

The company employed 2,114 people at year-end, with 713 (33.73 %) in R&D roles.

2. Revenue decline: volume and pricing

The 39 % revenue drop is a product of two forces working in tandem. Shipments fell 18.90 % to 1,521 MWh, reflecting a broader destocking cycle in the residential ESS channel, particularly in Europe. But the revenue decline was just over double the volume decline, meaning average selling prices fell sharply.

The implied ASP of approximately CNY 1,287/kWh (revenue divided by MWh shipped) marks a significant compression from prior-year levels. This mirrors the industry-wide trend of declining lithium carbonate prices flowing through to battery pack pricing, but Pylontech’s residential and C&I product mix — historically priced at a premium to utility-scale cells — may have faced additional pressure as European distributors worked through excess inventory accumulated during the 2022-2023 buying surge.

A quarterly revenue trajectory offers some encouragement: Q1 revenue was CNY 386 million, rising steadily to CNY 593 million in Q4. The sequential improvement suggests the destocking cycle may be bottoming.

3. ESS margins: overseas vs domestic

Pylontech’s geographic margin split reveals a significant divergence between overseas and domestic profitability.

Region Revenue share Gross margin
Overseas 93.79 % 30.33 %
Domestic 6.21 % 2.67 %
Blended 100 % 28.90 %

Overseas markets — primarily Europe, but also South Africa, Southeast Asia, North America, and Australia — delivered a 30.33 % gross margin. The domestic Chinese market, by contrast, generated a margin of just 2.67 %, barely above breakeven. Pylontech relies on overseas sales for virtually all of its gross profit, while the domestic business operates near breakeven.

This lopsided structure is both a strength and a vulnerability. It insulates Pylontech from the worst of China’s domestic price war, where utility-scale ESS bids have dropped below CNY 0.5/Wh. But it also means the company’s financial health is heavily dependent on maintaining price premiums in export markets — premiums that are under increasing competitive pressure as more Chinese manufacturers pursue the same overseas residential and C&I segments.

4. Product developments

Pylontech used 2024 to broaden its product portfolio beyond the residential LFP battery packs that built its brand.

Force-H3X

An evolution of Pylontech’s established Force series for residential storage, the Force-H3X targets the high-voltage home battery segment. This market is competitive, with products from BYD, Huawei, and a growing number of Chinese entrants vying for European installer partnerships.

Elva

A new residential energy storage system designed to complement the company’s existing product line. Details in the annual report are limited, but it appears positioned as a next-generation home storage solution.

M7 liquid-cooled C&I system

Pylontech’s entry into the commercial and industrial segment with liquid cooling represents a meaningful strategic expansion. The C&I ESS market is growing rapidly as commercial electricity users seek to manage peak demand charges and integrate on-site solar. Liquid cooling is increasingly expected for higher-power C&I applications where thermal management affects cycle life and warranty economics.

Sodium-ion home storage

Perhaps the most forward-looking announcement, Pylontech disclosed work on a sodium-ion battery for residential storage. Sodium-ion technology avoids lithium supply chain risk and could offer cost advantages at scale, though energy density remains lower than LFP. For home storage applications where space constraints are less severe than in EVs, sodium-ion could prove a practical alternative — particularly if lithium prices recover.

5. Manufacturing capacity and the 10 GWh expansion

Pylontech’s primary manufacturing base is in Yangzhou, Jiangsu province, operated through its subsidiary Jiangsu ZTE Pylontech Battery Co., with a secondary facility in Guangde, Anhui province (Anhui Pylontech). Production volume in 2024 was 1,801.56 MWh and sales volume was 1,521.00 MWh, reflecting the demand downturn in the company’s core residential ESS markets.

The company’s planned 10 GWh new R&D and manufacturing base, funded through the 2022 share issuance and originally scheduled for completion in April 2025, has been delayed to April 2026. The postponement is pragmatic given current demand levels. But the delay also signals that Pylontech’s growth ambitions have been forced to recalibrate against market realities.

6. Geographic mix: 93.79 % overseas

Pylontech is among the most export-dependent ESS manufacturers in China. With 93.79 % of revenue derived from overseas markets, the company’s fortunes are tied almost entirely to demand and pricing conditions outside its home market.

Europe has historically been Pylontech’s primary export destination, driven by the residential solar-plus-storage boom in markets like Germany, Italy, and the UK. The 2024 results reflect the hangover from the European residential ESS oversupply that began in late 2023, when distributors who had aggressively stocked inventory during the energy crisis found themselves overstocked as demand normalized.

The company holds BNEF Tier 1 status (Q4 2024) and a CSI ESG rating of AAA, both of which support its positioning for institutional and utility-scale customers in export markets.

7. Market context

Pylontech’s 2024 results must be read against a difficult backdrop for residential ESS globally.

The European residential storage market, which accounts for the bulk of Pylontech’s addressable market, experienced a sharp correction in 2024. After explosive growth in 2022 driven by energy price spikes, the market contracted as electricity prices fell, distributor inventories swelled, and consumer sentiment shifted. Multiple residential ESS-focused companies — both Chinese exporters and European brands — reported similar revenue declines.

At the same time, utility-scale ESS demand surged globally, but Pylontech’s product portfolio and brand positioning have historically been weighted toward the residential and smaller C&I segments. The company’s push into C&I with the M7 liquid-cooled system and its capacity expansion plans suggest awareness that residential dependence carries cyclical risk.

Pylontech is controlled by ZTE Xin Communications (中兴新), the parent company of ZTE Corporation, which provides strategic backing but also means the company’s governance and capital allocation operate within a larger corporate structure.

8. What to watch

The most pressing question for Pylontech is whether ASP erosion stabilizes. Revenue fell nearly twice as fast as shipment volumes, and even a recovery in unit sales will not restore financial health if per-kWh pricing continues to deteriorate. The quarterly improvement from Q1 to Q4 suggests some stabilization, but the direction of lithium prices and competitive intensity in European residential markets will be decisive.

The delay of the 10 GWh new R&D and manufacturing base from April 2025 to April 2026 buys time, but also raises questions about when — and whether — Pylontech will need that capacity. With 2024 production volume of just 1,801.56 MWh, the company has significant room to grow before the new base becomes necessary. The risk is that the project was sized for a market trajectory that has fundamentally shifted.

The domestic margin of 2.67 % is difficult to sustain for any extended period. It suggests Pylontech is selling in China primarily to maintain market presence and relationships rather than for profit. If domestic pricing does not improve, the rational move is to shrink the domestic business further — but that carries strategic costs in a market where government relationships and local track record matter for future policy-driven demand.

The broader destocking cycle in European residential ESS appears to be nearing its end, with multiple industry sources suggesting inventory levels normalized through late 2024 and early 2025. If this proves accurate, Pylontech could see volume recovery in 2025 — though pricing recovery is less certain.

Finally, Pylontech disclosed that its chairman was subject to detention measures during 2024, which were subsequently lifted. While the measures did not appear to disrupt operations materially, governance incidents of this nature can affect institutional investor confidence and banking relationships, particularly for an SSE STAR Market-listed company.
