Growatt Parallel Busbar Box for AXE Battery System

The Growatt Parallel Busbar Box (TV03.0012600) is designed to bundle the DC power and communication cables from multiple parallel-connected AXE HV battery clusters in a structured and safe manner. This accessory is crucial for ensuring a uniform charging and discharging current between the clusters, which maximises the stability and efficiency of the overall energy storage system.

Key Features

• Central DC Connection: Provides a common and optimised connection point for the DC power cables of parallel battery clusters.
• Structured Communication: Ensures the correct connection of the communication cables (RS485/CAN) between the clusters and the master unit or inverter.
• Clear Design: Compact and robust housing for a neat and professional installation.
• Specific to AXE HV : Exclusively designed for seamless integration with the Growatt AXE 5.0H battery system.

Main Advantages

• Scalability: Enables simple and reliable expansion of the total storage capacity by connecting multiple battery clusters in parallel.
• Current Balance: Improves current distribution and minimises resistance differences between parallel batteries, leading to a longer battery lifespan.
• Ease of Installation: Simplifies wiring and reduces installation time for complex, parallel setups.
• System Integration: Ensures optimal communication between all battery modules and the Growatt inverter.

Applications

The Parallel Busbar Box is suitable for larger residential or commercial projects that require significant energy storage, where the maximum capacity of one battery cluster (multiple stacked modules) is insufficient. It is essential for creating multiple parallel clusters of Growatt AXE HV batteries, often used in combination with Growatt hybrid inverters for applications such as peak shaving, backup power, and increasing self-consumption.

Warranty and Durability

As part of the modular Growatt AXE HV system, the busbar box is designed for a long operational life. The component contributes to the overall safety and sustainability of the battery system by ensuring correct electrical connections, which is crucial for the factory warranty on the battery modules and communication with the BMS.
