The Dyness PowerHaus lithium battery is a professional, fully protected, and scalable solution for stationary residential energy storage. With a nominal voltage of 51.2 V and a capacity of 100 Ah, each module stores 5.12 kWh of energy, and paralleling up to 50 modules allows for the creation of massive systems with a capacity of up to 256 kWh. The highest level of safety, including a built-in aerosol fire extinguisher, and an IP66 enclosure rating make this battery the benchmark for reliability for both indoor and outdoor installations. The PowerHaus battery system is designed to create powerful home energy storage systems (ESS) as part of solar power systems or as a backup power source. It addresses the challenges of achieving complete energy independence for a private home, maximizing on-site solar energy consumption, and providing long-term backup power during grid outages. With support for operation over a wide temperature range (including optional self-heating for operation at -20°C) and compatibility with most popular inverters, it is a ready-made solution for integration into any modern power system. - Highly protected housing with IP66 rating, providing complete protection against dust and powerful jets of water for safe outdoor or indoor installation.- Built-in active fire extinguishing system (aerosol fire extinguisher) for automatic fire suppression and ensuring the highest level of safety.- Exceptional durability: guaranteed service life of more than 8000 cycles or 10 years (at 95% depth of discharge).- High peak power: the ability to deliver a current of up to 200A for 2 minutes to start powerful loads (e.g. borehole pumps).- Scalability: the ability to parallel connect up to 50 modules to create systems of any required capacity.- Flexible installation options: support both wall and floor placement for optimal use of space.- Built-in Wi-Fi module for remote status monitoring, control and firmware updates (OTA) via a mobile application.- Optional automatic self-heating function for efficient operation in extremely low temperatures.
