SolaX TP30 BMS Parallel Box G2

SolaX TP30 Parallel Box G2: The Scalable BMS Interface for Multi-Stack Solar Storage Systems

The SolaX TP30 Parallel Box G2 is engineered for larger installations that require more than a single stack of solar batteries. By enabling up to three complete X-ESS battery stacks, each managed by its own BMU-3, this compact unit serves as the bridge between SolaX battery banks and your solar inverter. It’s a key component for scaling residential or light commercial energy systems efficiently.

Unlock Multi-Stack Battery Integration

While a single BMU-3 can control up to four X-ESS batteries, the TP30 Parallel Box G2 takes scalability further. It allows you to operate multiple BMU-managed stacks in parallel, unlocking expanded storage capacity while retaining full communication and safety protocols across the system.

• Supports up to 3 battery stacks with BMU-3 units
• Increases total usable energy for high-demand sites
• Optimised for use with SolaX Hybrid G4 inverters

Smart Communication and System Harmony

This unit ensures clean, centralised control of data and command signals across the entire battery infrastructure. Designed to simplify complex wiring, it improves system reliability and reduces installation time for larger systems where communication consistency is critical.

• Streamlined signal and control integration
• Ensures synchronised operation of all battery stacks
• Reduces risk of communication failure in scaled systems

Compact and Installer-Friendly Design

Despite its powerful role, the TP30 Parallel Box is compact enough to wall-mount in utility rooms or plant spaces. Its plug-and-play nature and robust design help installers deliver fast and fault-tolerant system upgrades without a mess of interconnecting cables.

Built for High-Capacity, Low-Hassle Installations

With the TP30 Parallel Box G2, installers can confidently scale systems to meet advanced energy needs, whether in large domestic properties, small commercial setups, or EV-ready households. It ensures the system remains intelligent, integrated, and ready for future energy demands.

• Compatible with high-performance X-ESS stacks
• Connects cleanly with SolaX inverters and BMU-3 units
• Enhances system monitoring and performance

Why Evergy Recommends This Product

We recommend the TP30 Parallel Box G2 for installers and engineers who need a reliable method to scale solar storage without compromising performance. It’s a must-have when designing larger systems with 2 or 3 parallel X-ESS stacks, especially when paired with our range of solar panels and mounting systems.

Where This Excels

The Parallel Box G2 is ideally suited to advanced energy setups such as EV-ready homes, high-consumption households, and commercial environments requiring large-scale backup or time-of-use optimisation. It helps futureproof your system while keeping it manageable and efficient.
