Configuration 3

Each Force-H2 group stacks FH9637M modules of 3.552 kWh / 96 V behind one battery controller.

  • Force-H2-V2: 2 to 4 modules per group, giving 7.10 / 10.65 / 14.20 kWh at 192 / 288 / 384 V, per the V2 manual.
  • First generation: the Force-H series datasheet allows 2 to 5 modules per group, up to 17.75 kWh at 480 V.
  • Parallel: up to 6 groups run in parallel; 6 x 17.75 kWh = 106.5 kWh, simple arithmetic on the datasheet figures.
  • Naming note: the 17.75 kWh tier is a de-linker bundle matching the five-module datasheet column, not a Pylontech model number.

One controller per group, and the generation must match: FC0500M-40S for the first-generation Force-H2, FC0500M-40S-V2 for the Force-H2-V2.

  • Separate systems: Pylontech's compatibility list treats Force-H2 and Force-H2-V2 as separate systems with separate controller firmware tracks.
  • Inverter pairing: some inverters pair with the V2 system only, so confirm the paired hybrid inverter against Pylontech's list before ordering.
  • Module ceiling: the V2 manual caps a group at 4 modules (14.20 kWh); only the first-generation system runs 5 modules (17.75 kWh).

No. The FH9637M belongs to the Force-H2 series only; Force-H3 stacks use the FH10050 module with the FC1000 controller.

  • Within Force-H2: the same FH9637M module serves both the first-generation and the V2 system; the controller defines the generation.
  • Expansion: add modules within the 2 to 4 (V2) or 2 to 5 (first generation) per-group window, or add parallel groups up to 6.
  • Check first: confirm inverter compatibility, usable capacity and expansion limits against the latest Pylontech documents during final technical approval.

Installation & wiring 1

The Force-H2 is a stacked tower with an IP55 enclosure.

  • Weights: each FH9637M weighs 35 kg (450 x 296 x 296 mm); the assembled five-module tower weighs 188.5 kg at 450 x 296 x 1710 mm, per the datasheet.
  • Environment: 0 to 50 C operation, 5-95% humidity without condensation, below 2000 m altitude.
  • Communication: the system talks CANBUS / Modbus RTU to the inverter; the controller carries RS-485 and CAN / RS-232 terminals.
  • Metering: the paired hybrid inverter typically requires a grid-side meter such as the Chint DTSU666 for export limiting, with the CT sized to the site's service current, not the battery current.

Availability & compliance 1

Pylontech lists the Force-H2 system against VDE-AR-E 2510-50, IEC 62619, IEC 63056, IEC 62040-1, CEC and CE.

  • Transport: UN38.3 covers shipment of the lithium modules.
  • Enclosure: IP55 ingress protection for the assembled system.
  • Documents: the Pylontech Force H2 datasheet is on file in English and German editions on this page.
  • Grid connection: grid-code certificates are not part of this battery listing, so we confirm the certificate set for your project and paired inverter with the quote.

Operation & warranty 1

Pylontech documents state two figures: the operation manuals rate the FH9637M module at 5,000 cycles, while the Force-H series datasheet states more than 8,000 cycles at 25 C for the system.

  • Depth of discharge: 95% per the datasheet.
  • Design life: 15 years or more at 25 C.
  • Both are Pylontech figures: the difference comes from the reference document, so treat the manual figure as the conservative basis.
  • Warranty basis: ask us for the warranty terms that apply to your batch; we confirm them with the quote.

General 1

Module counts differ between generations.

  • Force-H2-V2 manual: two to four modules per group (7.10 / 10.65 / 14.20 kWh)
  • First-generation Force-H series datasheet: two to five modules per group (7.1 up to 17.75 kWh)
  • Up to six groups run in parallel
