# Dyness Stack100 20.48 kWh energy storage system, HV, with heating

> Dyness Stack100 20.48 kWh is a high-voltage energy-storage configuration with four 5.12 kWh LiFePO4 modules. This catalogue version is marked with self-heating and includes CAN, RS485 and Wi-Fi communication for compatible hybrid-inverter systems.

## Product identity
- **Brand:** Dyness
- **Product family:** Dyness STACK100 high-voltage energy-storage system
- **Variant:** 20.48 kWh
- **SKU:** UCC020

## Description
Dyness Stack100 20.48 kWh is a high-voltage stack consisting of four 51.2 V / 100 Ah LiFePO4 battery modules. The configuration has 20.48 kWh nominal energy, 204.8 V nominal voltage and a maximum charge/discharge current of 100 A.

The Stack100 datasheet lists CAN/RS485 communication, a built-in Wi-Fi module, 95% depth of discharge and at least 8000 cycles. Its IP20 protection rating is intended for indoor installation. The product record is marked with self-heating; the series datasheet describes low-temperature charging support as an optional configuration, so the supplied configuration must be confirmed before ordering.

For the four-module configuration, the datasheet gives 590 × 765 × 390 mm dimensions. It must be paired with a compatible high-voltage inverter and installed to the manufacturer’s current electrical, ventilation and safety requirements.
