Description
SOFAR GTX3000BCU – control module for energy storage batteries 2.56 kWh
SOFAR GTX3000BCU is a control module forming the base of the GTX3000 series energy storage system. The device consists of a control unit and base with a total capacity of 2.56 kWh (50 Ah / 51.2 V DC) and enables the construction of a scalable energy storage system — simply add GTX3000 expansion modules, each adding 2.4 kWh of capacity, up to a maximum of 10 modules. The controller is compatible with inverters from various manufacturers, giving installers the flexibility to select components without being limited to a single ecosystem. The built-in LED panel (STATUS / SOC) allows for quick assessment of battery status directly on site, while remote diagnostics and real-time monitoring simplify servicing once the installation is commissioned. The module offers both wall and floor mounting, making it suitable for garages, boiler rooms and technical rooms with varying layouts. The high IP66 protection rating allows installation even in conditions of increased humidity.
Key advantages for the installer
- Automatic battery ID assignment with a single button — no manual address configuration required
- Scalable up to 10 GTX3000 modules — precise adjustment of storage capacity to the end customer's needs
- Long service life — over 6,000 cycles ensures years of trouble-free operation
- Compatible with inverters from multiple brands — one battery type for various system configurations
- Natural (fanless) cooling — no moving parts and quiet operation
