5.12kWh Energy Storage Capacity
Each Fox ESS LV52 battery module provides 5.12kWh of nominal energy storage. The modular design allows additional compatible battery modules to be installed where greater storage capacity is required, providing flexibility for different household energy consumption profiles and solar PV system sizes.
Battery storage can be used to store surplus electricity generated by solar panels during periods of high solar production and make that energy available when generation is lower, helping maximise the use of stored solar energy.
High-Efficiency 48V Battery Technology
The Fox LV52 is designed around a 48V low-voltage battery architecture and offers up to 95% charge and discharge efficiency. Its high efficiency helps reduce energy losses during battery charging and discharging, making it suitable for regular residential energy storage applications.
The battery also features CAN and RS485 communication interfaces for communication with compatible Fox ESS energy storage equipment and system components.
6,000+ Cycle Life
The Fox ESS LV52 is rated for 6,000 or more cycles, making it suitable for repeated charge and discharge operation. Cycle life is dependent on operating conditions, temperature, depth of discharge, charging and discharging parameters and the wider system configuration.
Scalable Modular Battery Storage
The LV52 forms part of Fox ESS's modular low-voltage energy storage range. Multiple compatible battery modules can be combined to increase total system capacity as required.
For installations using 2–4 batteries, Fox ESS requires two FE-JUNBOX-LV combiner boxes as part of the applicable battery configuration.
The LV52 can be used alongside the Fox ESS LV54, subject to the manufacturer's specified system configuration and compatibility requirements.
Easy Installation
The Fox LV52 has been designed for straightforward installation within compatible Fox ESS energy storage systems. Its modular architecture and communication interfaces simplify integration with supported Fox ESS inverters and battery system components.
Installations should always be designed and commissioned in accordance with the latest Fox ESS installation documentation, compatibility requirements and applicable UK electrical regulations.
Wide Operating Temperature Tolerance
The LV52 is designed to operate across a wide temperature range, providing flexibility for residential battery storage installations. Battery performance and available capacity can vary according to ambient temperature and operating conditions.
Fox ESS LV52 Compatibility
The Fox ESS LV52 is a dedicated low-voltage battery module and must be installed as part of a compatible Fox ESS energy storage system. Compatibility depends on the inverter, battery configuration, firmware and associated system components.
```LV52 and LV54 Compatibility
The Fox ESS LV52 and LV54 are compatible with each other when installed in an approved configuration.
LV52 and LV5200 Compatibility
The Fox ESS LV52 is not compatible with the LV5200. These battery models should not be mixed within the same battery system.
```Battery Combiner Box Requirements
When installing 2–4 Fox ESS LV52 batteries, two FE-JUNBOX-LV combiner boxes are required according to the supplied system configuration information.
The combiner boxes form part of the battery interconnection arrangement and should be selected and installed in accordance with Fox ESS system documentation.
CAN and RS485 Communication
The Fox LV52 incorporates CAN and RS485 communication for battery management and communication with compatible energy storage equipment. Correct communication cabling and configuration are essential for reliable battery and inverter operation.
Please note that the CAN cable supplied with certain Fox ESS LV54 battery configurations may be made up at the battery end only. Where applicable, the installer may need to terminate the inverter end of the communication cable in accordance with Fox ESS installation instructions.
Fox ESS LV52 Warranty Registration
The Fox ESS LV52 is supplied with a 5-year standard product warranty. Registering the installation with Fox ESS online is required to activate the extended 10-year product warranty, subject to the manufacturer's warranty terms and conditions.
Warranty registration should be completed following installation. Installers should retain the relevant installation information and review the current Fox ESS warranty documentation for the full warranty conditions, exclusions and registration requirements.
