Solis FlexHome-CB210A-L BMS 210A Home Battery Controller
The Solis FlexHome-CB210A-L is the central low-voltage BMS controller for the FlexHome-(5–40)kWh-L energy storage system. This control module manages communication, system protection and charge/discharge control between battery modules and compatible Solis LV hybrid inverters. With a maximum current of 210A and CAN/RS485 integration, it is the mandatory control unit for reliable low-voltage storage.
- Low-voltage BMS controller: 210A maximum charge/discharge current — system voltage 25V – 60V.
- CAN and RS485 communication: Seamless system integration with compatible Solis LV hybrid inverters.
- Intelligent system monitoring: SOC monitoring, charge cycle management and safety logic for all connected FlexHome-BAT5kWh-L modules.
- Mandatory system component: Required for correct control of all FlexHome-BAT5kWh-L battery modules.
- Compact and lightweight: 15 kg — dimensions 800 × 230 × 285 mm.
Suitable for
- New FlexHome-(5–40)kWh-L low-voltage home battery installations
- Installations with compatible Solis LV hybrid inverters (S6-EH1P, S5-EH1P, S6-EA1P series)
- Residential energy storage with scalable capacity from 5 kWh to 40 kWh per stack
- Systems requiring SOC monitoring, safety logic and controlled charge/discharge operation
- Installations requiring Time-of-Use optimisation and dynamic energy management
Solis FlexHome-CB210A-L — specifications and benefits

Which Solis LV inverters are compatible with the FlexHome-CB210A-L?
The FlexHome-CB210A-L is validated for the following Solis LV hybrid inverter series: S6-EH1P(3–6)K-L-EU, S5-EH1P(3–6)K-L, S6-EH1P(3–10)K-L-PLUS and the S6-EA1P series. Compatibility depends on the exact inverter model and firmware version. Firmware and communication settings must be correctly configured. Always refer to the most current compatibility list in the datasheet before installation.
Is the FlexHome-CB210A-L mandatory for the FlexHome-L system?
Yes. The FlexHome-CB210A-L is the mandatory BMS controller for the FlexHome-(5–40)kWh-L system. Without this controller, the FlexHome-BAT5kWh-L battery modules cannot operate and safe system management is not possible. The BMS handles cell balancing, temperature protection, SOC monitoring and communication via CAN/RS485 with the inverter.
How does the FlexHome-CB210A-L support Time-of-Use optimisation?
As time-of-use energy pricing becomes more widespread across Europe, accurate real-time system control is increasingly important for financial optimisation. The FlexHome-CB210A-L provides precise SOC and power data to the inverter, enabling the system to charge the battery during low-tariff periods and discharge during peak-price windows. The actual financial benefit depends on your consumption profile, PV yield, energy contract and applicable grid tariffs. With a scalable system from 5 kWh to 40 kWh per stack, the FlexHome-L system is built for long-term returns.
