Pylontech Force H3
A stackable high-voltage LFP battery of 2 to 7 modules of 5.12 kWh (10.24 to 35.84 kWh), IP65, with up to six groups in parallel.
- Best for large installed storage
- Installed battery
- 10.24-35.84 kWh
- IP65
- Made by Pylontech.
- Energy: 10.24 to 35.84 kWh, built from 2 to 7 FH10050 modules of 5.12 kWh each; 9.69 to 34.01 kWh usable at 95% depth of discharge.
- A high-voltage battery only: system voltage runs from 204.8 to 716.8 VDC and it connects to a compatible inverter. Pylontech's pages do not list which ones.
- Up to six groups in parallel. The numbers on this page are for the smallest stack (2 modules) unless stated.
- Model: Pylontech does not list a Force H2. The Force H3 is its current high-voltage residential series, next to the newer Force H3X.
Not tested by us
We have not tested the Pylontech Force H3. The figures on this page come from the sources listed at the end of the page, checked on 11 November 2026, and we do not show prices. "Best for" is based on what the maker says the product is designed for, not on our own tests.

Specifications
Last checked on 11 November 2026. The grey text under each name explains what the value means.
| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 10.24 / 15.36 / 20.48 / 25.6 / 30.72 / 35.84 kWh for 2 / 3 / 4 / 5 / 6 / 7 modules of 5.12 kWh (FH10050, 102.4 VDC each) |
| Usable capacityThe part of the stored energy you can actually use. It is lower than the nominal capacity. | 9.69 / 14.73 / 19.48 / 24.32 / 29.17 / 34.01 kWh for 2 to 7 modules |
| Depth of dischargeHow much of the battery can be emptied without harming it. 90% means 10% is kept in reserve. | 95% |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | Not stated in the sources we read |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | More than 10,000 cycles at 25 °C on the product page; the datasheet we read says more than 8,000. Design life 15+ years |
| ExpansionExtra battery units that add storage to the same system. | 2 to 7 modules per stack; up to 6 groups in parallel |
| Power | |
| Charge and discharge powerHow fast the battery can take in and give out energy. It sets how many devices it can serve at once. | Normal 50 A, maximum 55 A for 15 minutes (all sizes). Pylontech gives amps: about 10 kW normal at 204.8 V and about 35 kW at 716.8 V, calculated from its voltages |
| Round-trip efficiencyThe share of the energy you put in that comes back out. The rest is lost as heat. | Not stated in the sources we read |
| Backup in a power cutWhether it can keep selected circuits running during a grid outage. | Not stated in the sources we read |
| Solar | |
| Solar inverterTurns the DC power from solar panels into AC for the home. Built in means no separate solar inverter is needed. | None: this is the battery only. Pylontech's pages do not list compatible inverters |
| Connection and housing | |
| Grid connectionThe supply type it is built for. Check it matches your home's supply. | Not applicable: the battery connects to an inverter (system voltage 204.8 to 716.8 VDC, high-voltage DC) |
| Dimensions (W × D × H)Check the space before you buy, including room around it for airflow and cables. | 2 modules: 540 × 350 × 530 mm. Each extra module adds 170 mm of height: 700 (3), 870 (4), 1,040 (5), 1,210 (6) and 1,380 mm (7 modules); width and depth stay the same |
| WeightMatters for lifting, wall mounting and moving it. | 92 kg (2 modules), 131 (3), 170 (4), 209 (5), 248 (6) and 287 kg (7 modules) |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | IP65 |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Charging from -10 to 55 °C; storage -20 to 45 °C; humidity 5 to 95% without condensation; altitude below 4,000 m |
| ConnectivityHow you monitor and control it, usually through an app. | Modbus RTU and CAN to the inverter. A Wi-Fi portal installation guide is listed |
| CertificationsSafety and grid standards the maker says the product meets. | IEC 62040-1, IEC 62477-1, IEC 62619, IEC 63056, UL 1973, UL 9540A, UN 38.3, VDE-AR-E 2510-50 (the datasheet also lists UL 9540B) |
| Warranty | |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | Not stated in the sources we read |
Compatible with
What Pylontech says this product works with. Anything not listed here is not confirmed.
- Inverters
- Pylontech's product page and datasheet do not list compatible inverters. It communicates over Modbus RTU and CAN.
- Expansion
- Add modules to a stack (2 to 7) or add groups in parallel (up to 6 groups).
Rules where you live
An installed battery normally needs a qualified electrician, and in many countries you must also tell your grid operator, especially if it can export. This is not a plug-in battery. Rules, incentives and tax treatment differ by country: see our country guides for what applies where you live.
Strengths and things to check
Strengths
- Large and modular: 10.24 to 35.84 kWh in one stack
- Up to six groups in parallel
- 95% depth of discharge
- IP65, with a design life of 15+ years per Pylontech
- Modbus RTU and CAN communication
Worth checking before you buy
- A battery only: you need a compatible high-voltage inverter, and Pylontech's pages do not list which
- Heavy: 92 kg for two modules, 287 kg for seven
- Pylontech's product page and datasheet disagree on cycle life
- Warranty, efficiency and chemistry are not on the pages we read
Change log
We record changes to this page here, so you can see when figures such as the warranty were last updated.
- 11 November 2026
- Page published. Warranty at publication: not stated on the Pylontech product page or datasheet. Cycle life differs between the product page (more than 10,000) and the datasheet (more than 8,000). The newer Force H3X is not covered here.
Where this information comes from
We have not tested this battery. Every figure above comes from Pylontech's Force H3 product page and its Force H3 datasheet, last checked on 11 November 2026. Dimensions and weight are for the smallest stack (2 modules) unless stated. A value that these sources do not state is shown as not stated.
We do not show prices, because they depend on the installer's quote.

Common questions about Pylontech Force H3
How much does the Pylontech Force H3 store?
Pylontech lists 10.24 to 35.84 kWh, for stacks of 2 to 7 modules of 5.12 kWh, or 9.69 to 34.01 kWh usable at 95% depth of discharge. Up to six groups can run in parallel.
Is there a Pylontech Force H2?
We found no Force H2 on Pylontech's product list. The high-voltage residential series there is the Force H3, with the newer Force H3X next to it.
Does the Force H3 include an inverter?
No. It is a high-voltage battery only and talks to the inverter over Modbus RTU or CAN. Ask your installer to confirm that your inverter is compatible.
