Description

Product Description
The Sunsynk 61.44kWh 1C New battery is a high-capacity, high-voltage energy storage solution built using lithium iron phosphate technology for enhanced safety, durability, and long service life. Designed for demanding solar and backup applications, this system is ideal for large homes, commercial buildings, and industrial installations requiring substantial energy storage.

The system consists of multiple modular battery units, typically 12 x 5.12kWh modules connected in series to achieve a total capacity of 61.44kWh. Its high-voltage architecture improves overall system efficiency by reducing current losses and enabling seamless integration with compatible high-voltage hybrid inverters.

Equipped with an advanced Battery Management System, the battery continuously monitors cell performance, temperature, and charge levels to ensure optimal operation and protection. The 1C rating allows for high charge and discharge performance, making it suitable for peak shaving, load shifting, and backup during outages. Its rack-mounted, scalable design also allows multiple systems to be connected in parallel for expanded capacity.
