Pylontech Fidus Plus 16kWh LiFePO4 Battery, IP65 Self-Heating

• 16.076kWh nominal and usable battery capacity for larger 48V solar, backup and off-grid systems.
• Self-heating function supports charging in low ambient temperatures, with heating active between -20°C and 0°C.
• IP65 enclosure, C5-M anti-corrosion rating and optional aerosol fire-extinguishing module.

High-capacity 48V battery storage for demanding installations

The Pylontech Fidus Plus 16kWh LiFePO4 battery is a high-capacity, low-voltage energy-storage unit for compatible hybrid solar, backup-power and off-grid systems. The Fidus Plus range is designed for wall-mounted or floor-standing installation and provides a compact route to substantial usable storage capacity from one battery unit.

This self-heating Pro version is intended for environments that can experience cold conditions. Its battery heating activates between -20°C and 0°C to allow charging above 0°C, while the BMS limits charge and discharge current in extreme temperatures.

Key features

• 16.076kWh nominal capacity and 16.076kWh usable capacity, with support for 100% depth of discharge.
• 188A maximum continuous charge current and 200A maximum continuous discharge current.
• 300A peak charge/discharge current for 15 seconds.
• CAN and RS485 communications for compatible inverter and energy-management systems.
• Display screen, Bluetooth and Wi-Fi monitoring; optional aerosol fire-extinguishing module.

Where to use the Pylontech Fidus Plus 16kWh battery

Use the Pylontech Fidus Plus 16kWh battery in compatible 48V systems requiring significant stored energy in a single enclosure. Typical applications include commercial premises, workshops, agricultural sites, remote properties, larger residential backup systems and professionally designed off-grid installations.

For higher-capacity systems, up to 20 batteries can be configured in one battery group, with up to six strings. Multi-group parallel installations require the Pylontech LV-HUB-V2, which acts as the master unit. Confirm inverter compatibility, installation method, protection equipment and communications before ordering.

This battery requires professional system design and commissioning; it is not a plug-and-play product. UK expert support is available, and Energian can help arrange installation through trusted partners where required.

Technical specifications

*The battery supports 100% depth of discharge. Rated capacity is stated at 25°C and 0.2C discharge. The default lower state-of-charge limit is 5% and is adjustable.

**For multi-group installations, an LV-HUB-V2 is required for parallel connection and acts as the master unit. Each group supports a maximum of 19 batteries.

***The BMS limits charge/discharge current in extreme temperatures. Battery heating activates from -20°C to 0°C, allowing charging above 0°C.

****Cycle-life data is based on 25°C, a 0.2C charge/discharge rate and a 5%–95% state-of-charge range.
