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

The Growatt BDC 95045-A1 BMS acts as a central monitoring and control unit within the ARK high-voltage battery system and supports communication with Growatt MIN and MOD-XH inverters. It allows up to 10 battery modules with an individual capacity of 2.56 kWh to be connected. These modules can be connected in series to form a battery tower with a total capacity of up to 25.64 kWh. Storage towers can also be connected to each other, with one BMS 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
• Includes cable set and base

BMS control parameters

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

Flexible expansion

The ARK battery system from Growatt offers a high degree of flexibility thanks to its expandable configuration options, which range from 2.56 kWh to 25.6 kWh. The modular design and use of cables make installation and expansion of the system simple and straightforward. Another innovation of the ARK system is that, unlike other battery systems, it does not require a battery cabinet. Only a battery base is needed to ensure stability.

Connection and installation

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

The Growatt ARK battery base, which is also included in the scope of delivery, is specially designed for floor mounting of the ARK high-voltage modules. It ensures that the battery tower stands securely and forms the basis of the modular system. Up to ten storage modules and the associated BMS can be stacked on one base. One base is required per battery tower.
