NULITE offers optional solar PV compatibility across its entire heat pump product range, providing flexible and energy-efficient solutions for residential and commercial applications. By integrating with compatible solar PV systems, our heat pumps can utilize solar-generated electricity to help reduce grid power consumption and lower operating costs. We also provide professional OEM & ODM customization services, allowing customers to tailor product configurations, functions, branding and design to meet different market demands and project requirements.

Core Advantages

True Photovoltaic Direct-Drive Technology

Optional PV ready

This heat pump adopts PV DC direct-drive technology, in which the DC power generated by the photovoltaic system directly drives the compressor—no inverter and no battery required—thereby maximizing solar energy utilization. Under sufficient daytime sunlight, the product can achieve energy savings of up to 90%, with overall savings of approximately 60%. The system enables seamless switching between mains power and PV power, prioritizing PV power, with mains power automatically supplementing any shortfall in PV generation.

Solar PV Priority Energy Control

Universal PV Compatibility: Our cutting-edge photovoltaic direct-drive technology is not limited to a single model. It is available as an optional integration across our entire heat pump catalog, including Residential Air-to-Water (Heating & Cooling) Heat Pumps, Geothermal Heat Pumps, and Swimming Pool Heat Pumps etc.


Unmatched Energy Savings: In the best-case scenario, the electricity generated by the photovoltaic panels meets up to 90% of the consumption of the heat pumps.

Maximum Energy Harvest: Featuring Maximum Power Point Tracking (MPPT) technology, the system continuously adjusts to the optimal power point, ensuring maximum energy harvest from your solar panels.
