SolaX IES Series Box

SolaX IES Series Box: The Essential Expansion Tool for Multi-Stack TP-HS50E Battery Systems

The SolaX IES Series Box is designed to bring balance, protection and seamless communication to large-scale battery storage systems using the TP-HS50E modules. Whether you're deploying the IES 5.1kWh battery in a commercial setup or an energy-intensive home, this unit makes it possible to run two battery stacks as a single, unified system.

Dual-Column Battery Integration Made Easy

As soon as your project requires more than one battery column, the Series Box becomes essential. It allows two parallel groups of TP-HS50E batteries to be managed together, ensuring safe load balancing and intelligent communication between stacks. This unlocks larger energy capacities without compromising safety or system control.

• Required for systems with two TP-HS50E battery columns
• Maintains consistent charge and discharge patterns
• Compatible with both MCS0800E-D and TBMS-MCS0800E BMUs

Smart System Communication and Control

The Series Box ensures that all battery stacks communicate clearly with your battery management unit (BMU) and inverter. It allows the system to function as one cohesive energy storage bank, avoiding charge irregularities, safety risks, and system inefficiencies.

• Prevents imbalance between battery columns
• Coordinates BMU control across both stacks
• Tested and approved for all TP-HS50E system builds

Built for Larger Residential and Commercial Storage Projects

This compact, wall-mounted component supports hybrid and three-phase inverter systems in large-scale solar + battery applications. It’s perfect for energy users looking to futureproof their system by enabling higher capacity from day one or in future upgrades.

Why Evergy Recommends This Product

We recommend the IES Series Box for any TP-HS50E installation that requires two battery stacks. It’s an essential add-on that ensures your BMU can manage both columns efficiently, keeping your system safe and intelligently balanced at all times.

• Unlocks multi-stack battery scalability
• Prevents common communication and imbalance issues
• Pairs flawlessly with SolaX’s hybrid storage ecosystem

Ideal for High-Demand Storage Systems

The IES Series Box is best suited for homeowners and businesses using high-performance solar setups, who require more than 5–10kWh of usable battery storage. If you’re pairing your IES 5.1kWh modules with hybrid inverters and building a larger storage bank, this accessory is non-negotiable.

FAQs

Q: Do I always need the IES Series Box?
A: Only when using two battery stacks in one system. Single-column systems do not require the Series Box.

Q: Can I add this later?
A: Yes - if you're starting with one stack and plan to expand, the Series Box can be added during the upgrade process.
