BMS-Parallel Box-II Energy Storage Expansion Module

The BMS-Parallel Box-II is an innovative module that enables easy and efficient expansion of energy storage systems based on T-BAT H 5.8 batteries. It allows connecting additional batteries to X1 and X3 hybrid inverters, significantly increasing storage capacity. Its unique dual-circuit design improves reliability and extends the overall system lifespan.

Key features of the BMS-Parallel Box-II:

• Increased storage capacity: Allows connection of up to 8 T-BAT H 5.8 batteries with an X3-Hybrid inverter or up to 6 batteries with an X1-Hybrid inverter, creating large energy banks.
• Greater reliability and longevity: Creates two parallel, independent battery circuits, preventing system outages if one circuit fails and ensuring even cell wear.
• Simplified installation: Replaces the function of a master BMS module, so expanding the system does not require additional complex components.
• Intuitive status indication: Equipped with clear LED indicators that separately show operating mode and state of charge (25%, 50%, 75%, 100%) for each of the two battery circuits.
• High durability: Has an IP55 protection rating, providing protection against dust and water jets and allowing flexible installation.

Who is this a good choice for?

This is an essential device for owners of SolaX hybrid inverters (X1-Hybrid and X3-Hybrid series) who want to significantly increase their energy independence by expanding an existing or building a new high-capacity energy storage. It is ideal for single-family homes with high energy demand or for small businesses. With this module you can create a system with capacity of even over 46 kWh, providing reliable backup power and maximizing self-consumption of photovoltaic energy.
