The SRNE SE05B is designed for 48V-class inverter systems that support 51.2V 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 51.2V LiFePO₄ battery banks.

• This is a battery only. It does not include an inverter or solar panels.
• Confirm that your inverter supports 51.2V / 48V-class lithium batteries.
• For lithium communication, confirm CAN/RS485 compatibility with your inverter brand and model.
• Battery backup time depends on your connected appliances and total power consumption.
• For longer backup, the battery can be expanded in parallel up to 16 compatible units.
• The IP30 protection rating means it should be installed indoors or in a protected equipment area.
• Installation should include correct battery cables, breakers, protection devices, earthing and inverter battery settings.
• Use a qualified solar technician for installation and configuration.
