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 you to connect a larger number of batteries to X1 and X3 series 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 to an X3-Hybrid inverter or up to 6 batteries to an X1-Hybrid inverter, creating large energy banks.
- Greater reliability and lifespan: Creates two parallel, independent battery circuits, preventing system downtime 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 the operating mode and state of charge (25%, 50%, 75%, 100%) for each of the two battery circuits.
- High durability: Rated IP55 for protection against dust and water jets, allowing flexible installation.
Who is this a good choice for?
This device is essential 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 system. It is ideal for single-family homes with high energy demand or small businesses. With it, you can create a system with a capacity of over 46 kWh, providing reliable backup power and maximizing use of your own photovoltaic (PV) energy.
