The innovative Topband 48V solar rack battery, specifically designed for residential applications, serves as an excellent storage solution for your solar setup. 

This residential server rack battery is not only highly reliable, but also prioritises safety. Constructed with LiFePO4 chemistry and conforming to the highest international safety and transport standards, Topband ensures the utmost protection for your residential solar application.

With its modular and flexible design, the system can support up to 32 batteries in parallel, giving you the option of substantially expanding the overall energy capacity of your system. The automatic 'dynamic addressing function' is another remarkable feature, streamlining the process when multiple batteries are connected simultaneously.

Additionally, the built-in pre-charge circuit allows for a smooth connection with various inverter/chargers, avoiding any inrush current. 

Equipped with a built-in BMS, it provides warning and protection functions such as over-discharge, over-charge, over-current, short-circuit, and high/low temperature protection. The automatic cell balancing function is also designed to enhance the cycle life of the battery.

Furthermore, its compact size and light weight (46kg) make for easy installation and maintenance. It also offers multiple installation brackets to accommodate different set-up requirements.

With an LED display and CAN/RS485 ports for external communication and BMS firmware upgrades, this Topband Solar Server Rack Battery exceeds expectations while maintaining a very user-friendly and simplistic approach.
