Description
BREEZE ION BREEZE 4830 – LiFePO4 1.5 kWh 48V Battery Module with BMS
BREEZE ION BREEZE 4830 is a compact battery module with a built-in BMS management system, based on LiFePO4 cells with a usable energy of 1,536 Wh. Designed as a component of home energy storage systems working alongside photovoltaic installations — it enables the storage of surplus PV production and its use during hours without sunlight or during power outages.
Key benefits for the installer
- Plug&Play technology — quick connection without interfering with the existing grid inverter or the main meter
- Vertical or horizontal mounting — flexibility to adapt to conditions in the technical room
- Instant switching to backup power supply — without the need for an ATS
- Winter mode — enables off-grid operation during hours of more expensive energy
- Ability to combine up to 4 modules in a single string using BREEZE ConnectBox
- Durability of over 6,000 cycles at 80% DOD
Applications
- Residential photovoltaic installations — storing surplus energy from PV panels
- Backup power systems — continuity of power supply for critical loads during outages
- Energy consumption optimisation — winter mode operation allows the use of a cheaper tariff
The BREEZE mobile app enables remote monitoring of key module operating parameters: state of charge, charging and discharging current, fault states, individual cell balancing level, and temperature.
Connection diagrams
The diagrams below show variants of connecting ION BREEZE modules to an inverter — from a configuration with a single module, through a system with BREEZE Vertical and up to 4 batteries, to extended sets with a Deye inverter, a prefabricated switchboard, BREEZE ConnectBox and multiple modules connected via busbars.
