Energy Storage: LFP battery modules for PV systems
Energy Storage covers LFP battery modules, control units, a connection box and a stand for home and small commercial photovoltaic systems. The products let installers store surplus PV production and build scalable battery banks around Sofar, Solplanet and BREEZE ION components. The range is aimed at professional installers.
What you will find in this category
- Battery modules: LiFePO4 modules from 1.5 kWh (1.536 kWh usable) to 5.12 kWh (4.75 kWh usable), at 51.2 V or 400 V.
- Control units and modules: Sofar BTS 5K-BDU and GTX3000BCU, and Solplanet Ai-Hb 2.56 kWh modules for up to 8 modules.
- Connection hardware: Breeze Connect Box for parallel connection of up to 6 batteries, rated 180 A, with 1 kV insulation voltage.
- Stands: BREEZE vertical stand for 51.2 V stores from 2.5 to 10 kWh.
How to choose
- Capacity and scalability: check the module size and the permitted number of modules. GTX3000HV needs 4 to 10 modules, while Solplanet Ai-Hb systems take up to 8.
- Inverter compatibility: the BTS 5K module works with the BTS 5K-BDU unit and Sofar, HYD and ME inverters. GTX3000BCU is listed as compatible with inverters from multiple brands.
- Voltage and current: match the 51.2 V or 400 V rating and the charge and discharge current (25-30 A or up to 50 A) to the inverter.
- Mounting: BREEZE modules mount vertically or horizontally. GTX3000BCU mounts on a wall or floor, and BTS 5K-BDU is a floor-stand unit.
- Temperature range: operating limits differ by product. Compare the charging and discharging ranges against the installation site.
Typical applications
These modules suit residential and small commercial PV installations. They store surplus daytime production for use after dark or during power outages. BREEZE modules have built-in BMS and Plug&Play connection, so they can be added without changing the existing grid inverter or main meter.
Frequently asked questions
Which inverters work with the Sofar BTS 5K module?
The BTS 5K module works with the BTS 5K-BDU control unit. It is listed as compatible with Sofar, HYD and ME hybrid inverters.
How many GTX3000 modules does a system need?
GTX3000HV systems need at least four modules and can be configured with four to ten. The GTX3000BCU control module can be expanded up to 10 GTX3000 modules.
How many BREEZE batteries can the Connect Box join?
The Breeze Connect Box connects up to 6 batteries in parallel. Its rated current is 180 A across 6 channels, and one channel carries a maximum of 66 A.
