Dyness S51100 High-Voltage Battery for Stack / 51.2V 100Ah / 5.12KWh

The STACK100 energy storage system, built on Dyness S51100 51.2V 100Ah battery modules, is a modern high-voltage solution that ensures uninterrupted operation of an energy system. Together with the base platform and the control unit (BDU) it forms a complete stack compatible with new-generation hybrid inverters. Its main advantage is the ability to start with a small configuration and gradually increase capacity without changing the structure of the system.

The STACK100 system makes it possible to combine from 3 to 15 modules into a single stack, which provides a total capacity from 15.4 kWh to 76.8 kWh.

If required, several stacks can be connected in parallel, which makes the solution universal both for private houses and for facilities with high energy consumption.

Every module is equipped with a BMS, which:

• monitors the voltage and temperature of the cells
• performs balancing during charging
• protects against overload, overvoltage and deep discharge

In addition, the system includes a BDU (Battery Disconnect Unit), which is responsible for centralised management and safety. Data exchange with the inverter is carried out via CAN or RS485 interfaces, which guarantees stable operation and accurate monitoring of the battery status.

A system based on Dyness S51100 51.2V 100Ah makes it possible to:

• increase the share of self-consumption of solar energy
• provide backup power
• reduce peak loads
• improve the stability of the power supply

It automatically adapts to the operating modes of the inverter and the needs of the facility.
