Growatt BDC 95045-A1 bms control unit for MIN XH and MOD XH inverters

The Growatt BDC 95045-A1 BMS serves as the central monitoring and control unit within the ARK high-voltage battery system and supports communication with Growatt MIN and MOD-XH inverters. It allows you to connect up to 10 battery modules, each with a capacity of 2.56 kWh. These modules can be connected in series to form a battery tower with a total capacity of up to 25.64 kWh. Multiple storage towers can also be interconnected; one BMS is required per tower. The BMS is supplied with a Growatt battery connection cable set and a Growatt ARK battery base.

About the BDC 95045-A1 BMS

• Compatible with Growatt MIN-XH and MOD-XH inverters
• Modular, stackable battery concept
• Monitoring and control

BMS control parameters

The control parameters include state of charge (SOC), grid voltage, current, cell voltage, cell temperature, and the PCBA temperature measurement. By precisely monitoring these parameters, the BMS ensures optimal performance and service life of the battery.

Flexible expansion

The Growatt ARK battery system offers high flexibility with expandable configurations ranging from 2.56 kWh up to 25.6 kWh. Thanks to the modular design and cable connections, installation and expansion are straightforward and uncomplicated. Another innovation of the ARK system is that, unlike other battery systems, no battery cabinet is required. Only a battery base is needed to ensure a stable stand.

Connection and installation

The Growatt battery connection cable set included in the scope of delivery ensures a safe and stable connection between the battery and the inverter. The set includes two 2 m power cables (positive/negative), one 2 m communication cable, and one 2 m grounding lead.

The included Growatt ARK battery base is specially designed for floor mounting of the ARK high-voltage modules. It ensures a secure stand for the battery tower and forms the foundation of the modular system. Up to ten storage modules plus the associated BMS can be stacked on one base. One base is required per battery tower.
