PV DirectTM Drive for Commercial Solar Self-Consumption

The system helps commercial buildings use more of their own solar power instead of exporting excess electricity. This is especially useful for hotels, offices, schools and public buildings with high daytime energy consumption.

Scalable Integration

Our commercial heat pump system allows for seamless cascading of up to 16 units, ensuring efficient and reliable large-scale heating solutions. With advanced integration capabilities, this heat pump is perfect for meeting the diverse heating demands of commercial applications, providing consistent performance and energy efficiency across multiple units.

R290 Natural Refrigerant

R290 refrigerant supports high-efficiency heating performance and responds to the growing demand for low-GWP refrigerant solutions in commercial energy-saving projects.

Suitable for Energy-Saving Retrofit Projects

For commercial buildings with existing PV systems or plans for solar installation, this product provides a practical upgrade path from conventional electric heating or fossil-fuel-based systems.

Integrated MPPT Optimization

The MPPT control logic helps the heat pump respond to real-time solar conditions and improve the utilization of available PV power.
