Description
BREEZE ION BREEZE 4850 – LiFePO4 battery module 2.5 kWh 48V with BMS
BREEZE ION BREEZE 4850 is a compact battery module with a capacity of 2.5 kWh based on LiFePO4 cells, designed for residential and small commercial photovoltaic installations. Thanks to the built-in battery management system (BMS), the module provides protection against overcharging, excessive discharging and overheating, resulting in over 6000 cycles at 80% depth of discharge. The nominal voltage of 51.2 V and maximum current of 50 A (charge and discharge) allow flexible matching with popular hybrid inverters. The Plug&Play system significantly shortens commissioning time — modules are connected in parallel without the need to interfere with the existing PV installation, and the mounting orientation (vertical or horizontal) makes installation easier in limited spaces. The manufacturer provides a 20-year warranty, which minimises service risk for the installation company and builds trust with the end customer.
Key benefits for the installer
- Plug&Play technology — quick connection and configuration without specialist tools
- Unlimited scalability — modules connected in parallel retain the nominal capacity of new units, allowing the system to be expanded over time
- Vertical or horizontal mounting — flexible installation in boiler rooms, garages and technical rooms
- Instant switching to emergency power mode without the need for an ATS
- BREEZE mobile app for remote monitoring of state of charge, currents, temperatures and fault conditions
