The FoxESS battery is one of the most affordable new-technology solar batteries, helping homeowners achieve energy independence during blackouts or cloudy weather and run their appliances without interruptions.
It uses LiFePO4 prismatic cell technology, offering a 90% depth of discharge (DoD), more than 95% round-trip efficiency, and a cycle life of at least 6,000 cycles for reliable long-term performance.
Depending on the model, storage capacity can be expanded by connecting additional battery modules, with some FoxESS systems offering more than 40kWh of total capacity.
The battery supports charging and discharging currents that vary by model and number of connected modules, while CAN and RS485 communication enable integration with compatible inverters and monitoring systems.
It features natural convection cooling, IP65 protection, built-in battery management and safety protection, and supports charging temperatures from 0°C to 55°C and discharging temperatures from -10°C to 55°C.
The modular design allows floor or wall installation on compatible models and makes future capacity expansion easier. With plug-and-play installation, smart monitoring capabilities, and compliance with IEC 62619 safety requirements, FoxESS batteries provide a flexible and reliable option for storing excess solar energy and using it when required.
