Product Introduction
Demax’s Photovoltaic Direct-Drive Heat Pump Series operates via innovative photovoltaic direct-drive technology: DC current generated by solar panels is directly used to power the heat pump compressor through DC series boost technology (no inverter required). It integrates a built-in photovoltaic control module with Maximum Power Point Tracking (MPPT) (to maintain the solar panels’ optimal output) and intelligent dual-power (AC grid & DC photovoltaic) switching (to ensure stable power supply), while supporting multi-functional applications (heating, cooling, domestic hot water).
Main features
| Principle Module | Working Mechanism |
| Photovoltaic Direct-Drive Tech | DC current from solar panels directly powers the heat pump compressor via DC series boost technology (no inverter is required). |
| Photovoltaic Control Module | Built-in module with Maximum Power Point Tracking (MPPT) technology: monitors solar panel output voltage/current, and automatically adjusts to the optimal values to maintain maximum power output under varying light conditions. |
| Dual-Power Intelligent Switching | Supports AC grid & DC photovoltaic inputs: switches power sources in real time based on photovoltaic output (uses photovoltaic power preferentially; supplements with grid power when PV output is insufficient) to ensure stable, uninterrupted operation. |
| Core Features | Core Advantages | Application Scenarios |
| 1. Innovative photovoltaic direct-drive technology (no inverter required) | 1. Reduces initial investment cost by 10-15% (eliminates the need for an inverter & independent PV power generation equipment) | 1. Heating supply in winter |
| 2. Built-in photovoltaic control module with MPPT | 2. Ensures solar panels consistently operate at maximum power output under varying light conditions (via MPPT) | 2. Cooling supply in summer |
| 3. Dual-power (AC grid + DC photovoltaic) intelligent switching | 3. Maximizes PV power utilization (saves up to 90% energy in some scenarios) while ensuring uninterrupted operation (via dual-power switching) | 3. Domestic hot water production throughout the year |
| 4. Multifunctional (integrates heating, cooling, domestic hot water production) | 4. Enhances overall energy efficiency via year-round multi-functional use (maximizes PV power benefits) | - |
| 5. Uses R32 refrigerant | - | - |
