Pylontech Force H3 409.6V 20.48kWh HV battery system (4 cassettes + BMS controller and base)

The Pylontech Force H3 20.48kWh stacks four LFP modules into a 409.6V tower, giving a bigger home battery with no battery cables between modules.

With its furniture-like design and IP55 rating, it’s well-suited for home energy storage installations.

Designed for efficient setup, the Force H3 system requires no interconnection battery cables, greatly reducing installation time. Each base unit is a 5.12 kWh module, which can be stacked from a minimum of 2 to a maximum of 7 modules in a single tower, and expanded further by connecting up to 6 systems in parallel.
