The Polinovel 51.3V 160Ah sodium-ion battery delivers 8.208kWh of nominal energy in a floor-standing design. It integrates a BMS, a 4.3-inch touchscreen and CAN/RS485 communication for battery monitoring and inverter integration. With a compatible inverter, it stores solar energy for later use and supports backup power for selected household loads.
Specified for discharge down to −40°C, the battery offers an option for energy storage projects in cold climates. Charging is supported from 0°C to 60°C.
The upright enclosure provides a dedicated battery unit for floor installation. Its 560 × 230mm enclosure footprint helps installers plan the battery position and cable routing.
The built-in BMS monitors voltage, current and temperature, with protection against overcharge, overdischarge, overcurrent and short circuits.

With a compatible inverter, the Polinovel 51.3V 160Ah sodium-ion battery can support solar self-consumption, essential-load backup and off-grid energy storage.
Store surplus solar energy generated during the day for evening household use. As a sodium-ion battery for solar storage, it helps increase solar self-consumption and reduce reliance on grid electricity.
The integrated BMS monitors battery voltage, current and temperature during charging and discharging. Built-in protection, cell balancing and alarms help manage battery operation, while the 4.3-inch touchscreen provides local access to operating information.
Track battery voltage and charging or discharging current to check operating status.
Monitor battery temperature and apply protection when charging or discharging limits are reached.
Help manage voltage differences between cells through the BMS balancing function.
The Polinovel sodium-ion battery features CAN and RS485 communication for integration with a compatible inverter. Accessible power terminals and communication ports help organize electrical and data connections during system setup.
CAN & RS485 Communication
Exchange battery operating data with a compatible inverter through the supported communication interfaces.
Electrical Compatibility
Match the inverter’s battery voltage range and charge/discharge settings to the battery specifications.
Communication Cable Matching
Confirm the communication protocol and RJ45 pin assignment for both devices before connection.
The Polinovel 51.3V 160Ah sodium-ion battery comes in a vertical, floor-standing cabinet with a slim 230 mm-deep profile. The enclosure measures 560 × 230 × 830 mm (W × D × H), excluding mounting brackets and caster wheels. Bottom-mounted wheels make it easier to position the battery, while the side panel provides access to its power terminals, communication ports and controls.

Can the battery charge and discharge below freezing?
The specified discharge temperature range is −40°C to 60°C, while charging is specified from 0°C to 60°C. Low-temperature discharge capability does not mean the battery can charge below 0°C. Available output also depends on operating conditions.
Can multiple batteries be connected in parallel?
The battery includes IN/OUT ports for parallel communication. The supported number of batteries, wiring arrangement and system settings need to be confirmed before installation.
Which inverters are compatible with this battery?
Compatibility depends on the inverter’s battery voltage range, charge/discharge settings and communication protocol. The battery supports CAN and RS485, but matching interfaces alone does not guarantee compatibility. Share your inverter model with Polinovel for review.
How long can it supply backup power?
Backup time depends on the connected loads, usable battery energy and inverter losses. Its 8.208kWh nominal energy is a starting point for sizing; actual runtime also depends on the starting charge level and system settings.
Can this sodium-ion home battery work with solar panels?
Yes, when paired with a compatible inverter and suitable solar charging equipment. The battery stores surplus solar energy for later use. Solar panels should not connect directly to the battery.
