Description
Low-current high-voltage transmission for heavy winter discharge.
Pylontech Force-H3 20.48 kWh is a 409.6 V high-current high-voltage LFP storage tower combining an FC1000 master controller with four 5.12 kWh modules, delivering 50 A continuous discharge (20 kW max) and 19.45 kWh usable energy for large electrified homes and light commercial workshops.
409.6 V High-Voltage Bus for Low Cable Stress
Higher operating voltage reduces internal current stress, keeping operating temperatures low during heavy continuous discharges.
19.45 kWh Usable Storage Reserve
Deep 95% DoD capacity easily sustains whole-home evening domestic loads, EV charging, and multi-zone heat pump heating cycles.
50 A High-Current Power Delivery (20 kW Max)
Supplies commercial-grade power output to run heavy machinery, heat pumps, and dedicated emergency sub-panels.
Cable-Free Vertical Column Stacking
Consolidates 20.48 kWh into a single 97 cm column with internal slide-and-lock busbar mating.
More product details
Delivering 10–20 kW of continuous power from lower-voltage batteries generates extreme current stress and cable heating. Operating at 409.6 V nominal, the Force-H3 20.48 kWh delivers high power with minimal thermal losses.
- 128S series LFP cell string keeps operating temperatures low during sustained 10–20 kW discharge cycles.
- Direct DC coupling eliminates inverter step-up losses, maximizing seasonal energy efficiency.
- Deep 95% DoD extracts 19.45 kWh of usable energy across 6,000+ daily cycles.

20.48 kWh capacity in an ultra-lean single-column footprint.
Stacking 4 modules vertically reaches a clean 97 cm column height, preserving valuable workshop and garage floor space while isolating cells from floor moisture. Internal busbar contacts eliminate external high-voltage jumper cables and conduit runs. Integrated master DC circuit breaker isolates the stack automatically in sub-seconds during fault conditions. IP55 rated enclosure certified for unheated basements, technical utility rooms, and sheltered outdoor alcoves (-10 to +50 °C).
Holds 19.48 kWh of working storage
A cycle uses 19.48 kWh at 95 percent depth. The BMS keeps the rest of the rating.
Fits an 870 mm stack on a 540 mm face
This stack stands 870 mm. The face is 540 mm wide. Depth stays 350 mm.
Pairs six groups as one battery
Each group has its own FC1000. Six groups is the parallel ceiling. The hybrid still reads one state of charge.

Scenarios that show which projects the Pylontech Force-H3 20.48 kWh (4 x FH10050) belongs in, what to verify before quoting, and when another model is the better pick.
Large Electrified Residences & Small Workshops (14–20 kWp Solar Arrays)
Properties running multi-zone heat pumps, commercial tools, or EV chargers requiring up to 20 kW continuous discharge power from storage.
50 A throughput delivers full 20 kW power, while 19.45 kWh usable capacity provides the depth needed to sustain operations overnight.
- BoundaryIf the facility requires deeper overnight energy storage (> 20 kWh) to cover multi-day winter heating or multi-shift operations, step up to the higher capacity configurations. ---
- If the facility requires deeper overnight energy storage (> 20 kWh) to cover multi-day winter heating or multi-shift operations, step up to the higher capacity configurations. ---
