SolaX T-BAT high-voltage battery LiFePO4 2.5kWh TP-HS25

The SolaX TP-HS25 high-voltage battery module (MPN: 1020080208) is a 2.5 kWh LiFePO4 module designed for the T-BAT-SYS-HV-S2.5 high-voltage battery system. As part of a modular storage system, it efficiently stores excess energy from your PV system and makes it available again when needed. Thanks to modern LiFePO4 technology, an integrated battery management system (BMS), and optional battery heating, the system operates safely, durably, and reliably—even at low temperatures. With its stackable plug-and-play design, the battery system can be flexibly expanded from 5.12 kWh up to 33.28 kWh.

Maximum safety and intelligent battery management

The T-BAT-SYS-HV-S2.5 is designed as a full-fledged high-voltage battery system to meet the highest safety requirements. The built-in LiFePO4 cells are considered particularly thermally stable and durable. This is complemented by a powerful battery management system (BMS) that continuously monitors all relevant parameters such as temperature, voltage, and state of charge.

An integrated soft-start function protects the system from sudden current spikes. Additionally, the intelligent management system enables remote fault diagnostics, firmware updates, and maintenance. The optional battery heating technology ensures that the battery system can be reliably charged and discharged even at low temperatures.

Modular high-voltage battery system with flexible expansion

The TP-HS25 module is part of a flexibly scalable high-voltage battery system. Multiple 2.5 kWh modules can be stacked per tower. Just two modules form a system with a total capacity of 5.12 kWh. Depending on the number of modules used, the storage capacity can be expanded up to 33.28 kWh.

Thanks to the well-thought-out plug-and-play design, installation is quick and straightforward by simply stacking the modules. A parallel connection using a two-in-one cable is also available as an option to further increase the total capacity and further optimize the battery system’s lifespan.

High-performance for demanding PV systems

With a maximum charge and discharge current of up to 50A (depending on the system configuration and inverter), the high-voltage battery system delivers high performance for modern photovoltaic systems. The usable capacity is up to 90% DoD, enabling efficient storage and utilization of your solar energy.

Thanks to its wide operating voltage range, the system is ideally suited for high-voltage inverters and demanding self-consumption or commercial applications.
