Sunsynk’s top-grade 5.32kWh Lithium-Ion Phosphate batteries have been engineered to the highest standard. 

They are capable of up to 80% depth of discharge and scalable up to 16 times, allowing for a maximum of 85.12kWh per inverter. 

REPT Battery


Our BMS (Battery Management System) also offers a quick paralleling function, so no dip switches are needed, making installation straightforward. 


Our battery can be 1C rated in certain countries*, meaning that it will be able to charge or discharge at the full 5.32kWh.  This allows the end user to utilise the full potential of our inverter and battery systems. For more details please contact our customer service team.

* UK models are 0.5C 

Don't forget to fully charge your batteries upon installation.
