TL;DR
Differ Power announced its D1 Series, the first 9-in-1 heat pump system that combines heating, cooling, solar inverter, battery management, and backup power. It aims to transform the home into an integrated energy hub, with plans to debut at Intersolar Europe 2026.
Differ Power has announced the upcoming launch of the D1 Series, the world’s first 9-in-1 integrated solar-storage air-to-water heat pump system, which consolidates heating, cooling, domestic hot water, PV inversion, battery management, backup power, and home energy control into one platform. The system is designed for European residential applications and aims to position the heat pump as a central energy management hub rather than just a heating and cooling device.
The D1 Series combines multiple functions traditionally handled by separate devices, including space heating, cooling, hot water, PV inversion, and battery management, into a single unit. It uses the low-GWP refrigerant R290 and is tailored for homes with rooftop PV, including new builds and retrofits. The system’s hybrid inverter manages PV and battery operations directly, reducing energy conversion losses and increasing efficiency by over 10%, according to Differ Power.
It features an integrated emergency power function that switches household loads to backup power instantly during outages, with duration depending on battery capacity. Installation times can be cut by up to 50% compared to traditional multi-vendor setups, as the platform consolidates multiple components into one system. The system also supports major European grid standards, starting with the UK’s G98/G99 and Italy’s CEI 0-21, and offers capacities of 12 kW, 14 kW, and 16 kW for heating.
Revolutionizing Home Energy Management
This development signifies a shift toward integrated home energy systems that simplify installation, improve efficiency, and optimize the use of renewable energy. By combining multiple functions into a single platform, the D1 Series could reduce costs, streamline maintenance, and enhance the resilience of residential energy systems. It also aligns with the broader move toward electrification and decarbonization of homes, potentially accelerating adoption of renewable energy solutions.

Emerging Trends in Residential Energy Systems
Recent years have seen increasing interest in integrated energy solutions that combine solar, storage, and heating. Conventional setups involve separate devices, which can be complex and costly to install and maintain. Differ Power’s approach builds on advances in inverter technology, battery management, and smart controls, aiming to simplify and optimize home energy workflows. The announcement follows a growing market demand for systems that maximize self-consumption of solar energy and enhance grid independence.
“The D1 Series represents a significant step forward in residential energy technology by integrating multiple functions into one platform, potentially transforming how homes manage energy.”
