Photovoltaic DC Multi VRF
The Gree Photovoltaic DC Multi VRF is an intelligent, “new energy” climate solution that integrates solar power generation directly with HVAC operations to target zero carbon emissions and “zero electricity charges”. Utilizing proprietary DC direct-driven technology, the system achieves a solar utilization rate of up to 98% by eliminating energy-wasting conversion stages, while the integrated G-IEMS energy management system intelligently balances power between solar modules, the public grid, and optional battery storage. This system provides building owners and MCSTs a highly efficient path toward energy independence and is best used for green-certified commercial and public infrastructure, such as schools, hospitals, hotels, and office complexes, where sustainability and reducing high operational costs are primary objectives
Supported Indoor Units
Superior Energy Efficiency
- Direct-Driven Technology: The system utilizes “photovoltaic DC direct-driven technology” to power the unit directly from solar modules, achieving a utilization rate of up to 98%.
- Reduced Conversion Losses: By avoiding multiple AC/DC conversion stages, the system improves overall efficiency by more than 6% compared to non-direct-driven solar systems.
- Sustainability Goals: It is specifically designed to achieve zero carbon emissions and “zero electricity charges” under optimal conditions
Economic and Financial Benefits
- Grid Interaction: Surplus electricity can be sent to the public power grid in real-time or stored, ensuring no waste of excess solar energy and creating an economic benefit for the user.
- Peak-Valley Arbitrage: The system helps solve the problem of high electricity costs by avoiding peak-power pricing through its flexible power sourcing
Enhanced Reliability and Safety
- Durable Components: The unit uses membrane (film) capacitors instead of electrolytic capacitors; these offer higher voltage resistance, are non-polar, and provide a longer service life.
- Low-Voltage Safety: The use of low-voltage DC components reduces the danger of electrical shocks, arcing, and fire hazards compared to traditional high-voltage systems
- Adaptive Technology: The system features “Full Network Adaptive Low Voltage DC Technology,” ensuring stable operation and grid frequency self-adjustment
Simplified Engineering and Installation
- Lower Material Costs: The design eliminates the need for a combiner box and a neutral wire, which reduces overall engineering installation costs and labour.
- Worry-Free Interaction: The system is “full network adaptive,” meaning it self-adjusts to the grid frequency and voltage, making grid interaction eco-friendly and “worry-free
