Product Overview
The Pylontech Fidus Plus FB-L-16 is a 51.2V lithium-ion energy storage battery designed for residential solar and backup-power systems. It provides a manufacturer-stated usable capacity of 16.076kWh in an IP65 enclosure, with wall-mounted or floor-standing installation options to suit space-conscious energy-storage installations.
Key Features
- 16.076kWh nominal and usable capacity for substantial residential energy storage.
- 51.2V nominal battery voltage with up to 200A continuous charge and discharge current.
- Manufacturer-stated 100% depth of discharge rating, with a default lower state-of-charge limit of 5% that is adjustable.
- IP65 enclosure rating and C5-M anti-corrosion classification for demanding installation environments when installed according to manufacturer requirements.
- Wall-mounted or floor-standing design to suit different installation layouts.
- CAN and RS485 communication interfaces for integration with compatible energy-storage equipment.
- Display screen, Bluetooth and WiFi interaction capabilities for local monitoring and connectivity.
Applications
- Residential solar energy-storage systems.
- Home backup-power installations where a larger battery capacity is required.
- Hybrid and off-grid systems designed around compatible 51.2V battery equipment.
- Installations requiring a wall-mounted battery or an alternative floor-standing arrangement.
Why Choose This Product?
The Fidus Plus FB-L-16 combines a high-capacity 51.2V battery platform with 200A continuous charge and discharge capability, natural cooling and an IP65 enclosure. Its compact vertical format, communication interfaces and monitoring features make it a practical option for appropriately designed residential energy-storage systems.
Important Notes
- Installation and system commissioning should be completed by a qualified electrician or suitably qualified solar installer.
- Confirm inverter compatibility, communication settings, protection equipment and system configuration before purchase or installation. CAN and RS485 interfaces do not confirm compatibility with every inverter.
- Wall mounting must be assessed by the installer for the 130kg battery weight and suitable fixing method. Mounting hardware supplied is not specified in the datasheet.
- The stated 8,000-cycle life is based on 25°C, 0.2C charge/discharge conditions and a 5% to 95% state-of-charge range. Actual performance and service life depend on installation conditions and use.
- The datasheet lists aerosol fire extinguishing as optional; confirm whether this option is included with the supplied battery.
