Compatibility
The SRNE EOS02B-12 is designed for 12V-class inverter systems that support 12.8V lithium batteries. It can work with compatible hybrid and off-grid inverters, subject to correct battery voltage settings, charge/discharge current limits and communication protocol support.
For lithium communication, confirm that your inverter supports the battery’s CAN/RS485 protocol. Where direct communication is not available, some inverters may still allow configuration using user-defined lithium battery settings.
This battery is suitable for compatible SRNE inverters and other inverter brands that support 12.8V LiFePO₄ battery banks.
Best For
The SRNE EOS02B-12 is best for small homes, shops, offices, CCTV backup, router backup, lighting circuits, TV backup and compact 12V solar inverter systems. It is ideal for customers who need a dependable lithium replacement for traditional 12V lead-acid battery banks.
What to Consider Before Buying the SRNE EOS02B-12 2.56kWh 12.8V Lithium Battery
- This is a battery only. It does not include an inverter or solar panels.
- Confirm that your inverter supports 12V / 12.8V lithium batteries.
- Do not connect it directly to 24V or 48V inverter systems unless the full battery configuration is properly designed by a technician.
- For lithium communication, confirm CAN/RS485 compatibility with your inverter brand and model.
- Backup time depends on your connected appliances and total power consumption.
- For longer backup, the battery can be expanded in parallel up to 4 compatible units.
- The IP30 rating means it should be installed indoors or in a protected equipment area.
- Use a qualified solar technician for correct cables, breakers, inverter settings and protection devices.
