Product Details

NULITE Smart Photovoltaic Inverter Heat Pump System

The NULITE Smart Photovoltaic Inverter Heat Pump System combines air source heat pump technology with solar photovoltaic power. It allows the heat pump to connect directly with PV panels, reducing dependence on grid electricity and helping users lower energy costs.

This system is designed for all-season comfort. It provides heating in winter, cooling in summer, and domestic hot water throughout the year. With intelligent inverter control, the unit automatically adjusts its operation according to the real-time heating or cooling demand, improving efficiency while maintaining stable indoor comfort.

Key Features

1. Photovoltaic Direct Connection

The heat pump can be directly connected to solar PV panels. No extra conversion equipment is required. When solar power is sufficient, the system can operate mainly with solar energy. When sunlight is weak, the system automatically uses grid power as a supplement.

Working modes:

Grid Power Mode
At night or when there is no sunshine, the heat pump operates with grid power like a normal heat pump.

Grid + Solar Mode
On cloudy days or when sunlight is weak, the system prioritizes solar energy and supplements with grid power when needed.

85%–100% Solar Mode
When solar energy is sufficient, the heat pump can run mainly or fully on solar power, helping reduce electricity consumption and operating costs.

2. 3-in-1 Comfort Solution

The system supports multiple functions in one unit:

• Space heating
• Space cooling
• Domestic hot water
• Floor heating
• Fan coil unit connection
• Radiator heating
• Shower hot water supply

This makes it ideal for villas, residential houses, apartments, hotels, and other buildings requiring efficient heating, cooling, and hot water.

3. DC Inverter Technology

The NULITE photovoltaic heat pump uses DC inverter technology to adjust compressor and system output according to real-time demand. Compared with traditional fixed-speed systems, inverter operation helps improve energy efficiency, reduce start-stop frequency, lower noise, and extend system lifespan.

4. Built-in 3kW E-Heater

A 3kW auxiliary E-heater is built into the system. It provides extra heating support in low-temperature conditions, helping ensure stable operation and reliable hot water or heating performance during cold weather.

5. High-Efficiency Plate Heat Exchanger

The system is equipped with a high-efficiency SWEP plate heat exchanger. It features compact structure, fast heat transfer, space-saving design, and wide operating pressure and temperature range.

6. Built-in Expansion Tank

The built-in expansion tank helps absorb water pressure fluctuations and protects the system piping. This improves system stability and makes installation easier.

7. Inverter Water Pump

The inverter circulation pump automatically adjusts water flow according to system demand. This helps save energy, reduce operating noise, and improve overall system performance.

8. Smart WiFi Control

With WiFi function, users can control and monitor the heat pump remotely through a mobile device. The system supports convenient temperature adjustment and mode switching for heating, cooling, and hot water.

9. Multi-Language Controller

The controller supports multiple languages, making it suitable for international markets. Available languages include Chinese, German, Spanish, French, Italian, Czech, Polish, Danish, English, Dutch, Turkish, Lithuanian, Russian, Estonian, and Ukrainian.
