Who is Pylontech
Pylon Technologies Co., Ltd, usually known as Pylontech, is a Chinese energy storage company. The company was founded in 2009, originally as a subsidiary of the telecoms group ZTE Holdings. Pylontech bases itself in Shanghai, where it has built a global headquarters with its own testing laboratory. It is also publicly listed on the Shanghai Stock Exchange’s STAR Market, under ticker 688063.
BloombergNEF names Pylontech a Tier 1 global energy storage manufacturer. The company also says its lithium iron phosphate (LiFePO4) batteries serve more than 80 countries.
Unlike several of the brands covered on this site, Pylontech does not sell a packaged whole-home system through its own storefront and app. Instead, its core business is manufacturing stackable battery modules. Installers and inverter manufacturers pair these modules with a separate, compatible inverter. Pylontech sells them through an international network of distributors and installers, rather than direct to homeowners.
The Pylontech product range
Pylontech’s best-known line is the US series: low-voltage, 48V modules including the US2000(C), US3000C and US5000. Each one is a self-contained unit with its own battery management system that slots into a rack alongside others. Individual modules run from around 2.4 kWh (US2000C) up to around 5 kWh (US5000).
Pylontech’s own datasheets confirm a maximum of 16 units in a single string across the whole US series. This limit covers the US2000C and US5000 alongside the US3000C. Multiple strings can then run in parallel for larger installations. Pylontech also specifies a 95% depth of discharge across the range. For example, a US2000C’s 2.4 kWh nominal capacity gives around 2.28 kWh usable. The same 95% figure carries through to the US3000C, US5000 and Force H3 alike.
Meanwhile, the Force series, Force H2 and Force H3, are high-voltage modules. These come in around 3.55 kWh and 5.1 kWh sizes respectively. Installers stack them into taller strings, typically two to four modules per string. They then parallel several strings to reach tens of kilowatt-hours in a single system. Pylontech has also introduced the Force H3X, a newer variant. It bundles a battery stack with its own inverter and energy management as more of an all-in-one package. Its core business, though, remains the standalone modules described above.

Key technology behind Pylontech batteries
Every Pylontech module uses lithium iron phosphate (LiFePO4) cells. Experts generally regard this chemistry as safer and more thermally stable than other lithium formats. Each module’s own battery management system handles cell balancing and protection. Modules communicate with each other and with the inverter over RS485 or CAN in a master/slave arrangement. This arrangement lets several units stack together and read as one larger battery.
Pylontech publishes a compatibility list covering a very wide range of hybrid and off-grid inverters. These include Victron Energy, Deye (Sunsynk), Sofar, Growatt, SolaX, GoodWe and Sungrow, among many others. This broad compatibility is a large part of why DIY and off-grid solar builders use the brand so widely. Pylontech does not provide its own consumer-facing monitoring app. As a result, day-to-day monitoring and control normally happen through whichever inverter’s app or platform the system is built around. For example, that might be Victron’s VRM or the relevant inverter manufacturer’s own portal.
Strengths and limitations
Pylontech’s long track record in the battery-module market is genuinely one of its strongest points. That said, it is still worth weighing against what the brand does not offer compared with packaged whole-home systems.
Strengths
- Long track record as a specialist LiFePO4 module manufacturer, in the market since 2009 and rated a Tier 1 supplier by BloombergNEF
- Works with a very wide range of third-party inverters, including Victron, Deye (Sunsynk), Sofar, Growatt and many more, so it rarely locks you into one inverter brand
- Modular, stackable design lets a system grow in roughly 2.4 to 5 kWh steps rather than committing to one fixed size upfront
- A UK/EU warranty of 7 years as standard on its US series modules, free to extend to 10 years by registering the product with Pylontech, and 10 years as standard on its Force H series, each with a minimum retained-capacity commitment
Worth checking before you buy
- You need a separate, compatible inverter or charge controller; Pylontech does not sell a packaged whole-home system with its own monitoring app the way some brands do
- Published cycle-life figures vary by model and depth of discharge, with Pylontech's own datasheets ranging from around 4,500 to 8,000 cycles, so check the exact model's current datasheet rather than relying on a general brand-level number
- Commissioning typically needs a reasonably confident installer or DIY electrician comfortable configuring both the battery and the inverter, rather than a true plug-and-play setup
- We have not independently tested Pylontech's pricing, support or installation process ourselves
Where Pylontech fits the market
Pylontech sits in the installer and DIY/off-grid segment of the market globally. It is not part of the direct-to-consumer, plug-in segment that this site covers elsewhere, through brands such as EcoFlow, Anker or Indevolt. Nor is it a like-for-like competitor to whole-home branded systems such as Tesla or GivEnergy. Those brands bundle their own inverter, app and installer network, whereas Pylontech supplies only the battery modules.
In practice, installers and confident DIY or off-grid builders most often choose Pylontech. They typically have already picked, or are pairing it with, a compatible inverter from brands such as Victron, Deye, Sofar or Growatt. If you are still working out what capacity your home actually needs, our capacity guide and free calculator can help. Both cover that ground independently of any one brand or inverter choice.
Common questions about Pylontech
What is Pylontech and what does it make?
Pylontech is a Chinese battery manufacturer, founded in 2009. The company makes stackable lithium iron phosphate (LiFePO4) battery modules for home and commercial energy storage. Unlike some whole-home brands, it does not sell a complete packaged system. Instead, Pylontech designs its modules to be paired with a separate, compatible inverter chosen by you or your installer.
Can I install a Pylontech battery myself?
Pylontech's modules are popular with confident DIY solar and off-grid builders, particularly those already using inverters such as Victron, Deye or Growatt. That said, installation still involves battery wiring, communication cabling and inverter configuration. If you are not experienced with electrical work, use a qualified installer, and always follow your local wiring regulations.
Which inverters work with Pylontech batteries?
Pylontech publishes a compatibility list covering a large number of hybrid and off-grid inverter brands. These include Victron Energy, Deye (Sunsynk), Sofar, Growatt, SolaX, GoodWe and Sungrow, among many others. Compatibility and the exact communication setup can vary by model and firmware. So, check Pylontech's current compatibility list against your specific inverter before buying.
Is Pylontech good for off-grid systems?
Yes. Installers widely use Pylontech batteries in off-grid and self-build solar installations, especially alongside Victron and similar off-grid inverter setups. This is thanks to their broad inverter compatibility and stackable design.
What is the difference between Pylontech's US series and Force series?
The US series, such as the US2000, US3000C and US5000, are low-voltage, 48V modules aimed at typical hybrid inverter setups. Meanwhile, the Force series, Force H2 and Force H3, are high-voltage modules that stack into taller strings for larger systems. Both use the same LiFePO4 chemistry and a similar modular stacking approach.
How long do Pylontech batteries last?
Pylontech's current UK/EU consumer warranty gives its US series modules (US2000C, US3000C, US5000) 7 years as standard, with a minimum 70% retained capacity. You can extend this to 10 years (minimum 60% retained capacity) free of charge, by registering the product with Pylontech. Its Force H series, including Force H2 and H3, carries a 10-year warranty as standard with a minimum 80% retained capacity. No registration is needed for this. Warranty terms vary by region, however. Pylontech's Australian warranty document, for example, states a flat 10 years as standard on the US series. Always check the specific document that applies to your market. Beyond the warranty, the company generally cites cycle life figures around 6,000 cycles. Individual datasheets, though, list figures ranging from about 4,500 to 8,000, depending on the exact model and depth of discharge. As with any battery, real-world lifespan depends on usage patterns and operating conditions.
