The Dyness PowerHaus is a rugged low-voltage (51.2 V / 48 V-class) LiFePO₄ battery module designed for residential energy storage where outdoor capability, safety and modular expansion matter. Each unit provides 5.12 kWh and the system can be expanded up to 50 modules in parallel (up to 256 kWh) to match anything from a small home ESS to larger residential / light commercial projects. 

Why installers choose PowerHaus

• Outdoor-ready IP66: dust-tight and protected against powerful water jets, suitable for indoor or outdoor installation. 

• Ultra-safe design with built-in fire protection: integrated aerosol fire extinguisher and an “intelligent fire extinguishing system” designed to detect and extinguish in seconds. 

• High usable energy: 95% DoD and long service life (specified ≥8000 cycles / 10 years under stated test conditions). 

• Scales cleanly: 1–50 modules in parallel (5.12–256 kWh) for easy capacity growth. 

• Optional self-heating: supports low-temperature operation (charging down to -20°C when the optional function is used, per datasheet). 

• Monitoring & updates: built-in Wi-Fi module with app + OTA updates.

Integration & compatibility

PowerHaus is designed to work with a wide range of low-voltage hybrid / storage inverters via CAN or RS485. The datasheet lists compatibility examples such as Solis, GoodWe, Growatt, SMA, Victron, Deye, APsystems (and others). Always verify your exact inverter model + firmware + comms protocol before commissioning, especially for multi-battery parallel systems.
