Availability & compliance 2

The FB-L-16 is certified to the relevant lithium-battery safety standards, but grid compliance sits with the inverter, not the battery.

  • Battery certification: IEC 62619 and IEC 63056, transport-tested to UN38.3, CE/EMC marked
  • Grid codes: VDE-AR-N 4105 or EN 50549 apply to the inverter, not to a DC-coupled battery; grid compliance of the overall installation comes from the hybrid inverter you pair it with

Choose an inverter certified for the German grid and check its battery-approval list.

All three share the 51.2 V / 16,076 Wh core with 180/200 A continuous current and 300 A / 15 s peak.

  • FB-L-16 (this product, 120 kg): charges from 0 C, IP65
  • FB-L-16-Pro (122 kg): adds low-temperature capability, charging and discharging from -20 C, for cold sites
  • FB-L-16-PK (130 kg): the indoor variant with an IP20 enclosure and up to 20 units per group

Choose by installation environment; all are RFQ items with us.

Configuration 3

The Fidus Battery Plus is a 51.2 V low-voltage battery that communicates with the inverter over CAN or RS485, the interface used by common low-voltage hybrid and off-grid inverters.

  • Broad support: Pylontech's LV batteries are known for broad third-party inverter support; the sibling Fidus Pro datasheet advertises 50+ compatible inverter brands
  • Approval is model-specific: confirm that your inverter's battery-compatibility list includes the FB-L-16 firmware profile before ordering, or ask us to check for your project

The current official spec allows up to 16 units in one battery group and up to 6 parallel strings (groups).

  • Multi-group setups: the Pylontech LV-HUB-V2 is required as the parallel master; the datasheet footnote limits groups to 19 batteries with the hub
  • Capacity: with 16 kWh per unit, this supports storage banks well beyond residential scale

Always size the DC bus, cabling and inverter charging current to the bank, and confirm the group layout with the quote.

Yes, with a caveat on cold-weather charging.

  • Enclosure: IP65 (water-jet and dust resistant) with C5-M anti-corrosion for coastal air
  • Discharge range: down to -20 C
  • Charging limit: the base FB-L-16 charges only between 0 C and 55 C, so in an unheated garage or outdoor mounting in a German winter the battery may refuse to charge on cold mornings
  • Cold-site fix: for cold sites, specify the FB-L-16-Pro variant, which charges and discharges across -20 C to 55 C (battery heating activates between -20 C and 0 C per the datasheet)

Operation & warranty 1

  • Design life: 15 years (at 25 C)
  • Cycle life: 8000 cycles (at 25 C, 0.2C, SOC 5-95%)
  • Warranty: Pylontech has not published a model-specific warranty-retention figure for the FB-L-16 on the datasheet; warranty terms follow the manufacturer's warranty policy for your market, so request the current warranty document with your quote
