The 20kW-24kW Three-Phase Off-Grid Solar Inverter from HuiJue Group is an advanced, high-performance inverter designed for large-scale off-grid solar power systems. It provides reliable and efficient power conversion for energy needs in remote locations, commercial setups, and industrial applications. This inverter is capable of managing high loads, ensuring continuous power supply while optimizing solar energy storage and consumption.
Engineered for Complete Energy Independence
This isn't just an inverter; it's an autonomous power plant that intelligently manages multiple energy sources to guarantee your electricity is always on.
- Triple-Source Intelligence: Utilizes fully digital dual-loop control to automatically and seamlessly switch between three operational modes: solar-only (using real-time PV energy), battery-only (for night-time or cloudy days), and hybrid mode (combining both for heavy loads).
- Self-Starting Reliability: Features automatic utility/PV self-start. The system can reboot itself automatically when solar power returns or a generator is connected, eliminating the need for manual intervention after a complete battery shutdown.
- Robust Three-Phase Output: Delivers stable 400V three-phase AC power, essential for running heavy-duty equipment like water pumps, agricultural motors, workshop machinery, and multi-zone air conditioning systems found in larger homes or facilities.
Key Features & Technical Advantages
1. High Efficiency & Superior Energy Harvest
Maximizes every watt of available solar energy to reduce dependence on backup generators and extend battery life.
- Industry-Leading Efficiency: Achieves up to 95.5% inverter/charging efficiency, surpassing many mainstream models, which translates to more usable power and less energy lost as heat.
- High-Capacity PV Array Support: Accepts large solar arrays (up to 20kW or 24kW input) to capture ample energy even in lower-light conditions, paired with 2 or 3 independent MPPT trackers for optimized harvest from different panel groups.
- Compact, Cool-Running Design: Engineered to be 30% more compact than comparable units, with optimized thermal management that generates less heat for enhanced long-term component reliability.
2. Intelligent Power Management & Scalability
Offers smart control and the ability to grow with your energy needs.
- Smart Dual Output Management: Allows for prioritized load management. You can designate critical loads (e.g., refrigeration, lights) and general loads, with customizable settings for the secondary output's switch timing and shut-off voltage to conserve battery power.
- Unparalleled Parallel Capability: Supports the parallel connection of up to 9 units. This enables you to scale your system's power output from tens of kilowatts to over a megawatt, perfect for large farms, resorts, or small communities.
- Advanced Battery Compatibility & Management: Works seamlessly with a wide range of battery technologies, including Lithium-ion, Lead-acid, and Vented Lead-acid. Its smart battery management can activate protected lithium batteries and dynamically adjust charging curves for optimal health and speed.
3. User-Centric Design & Durability
Built for ease of use, quiet operation, and longevity in demanding environments.
- Smart Noise Control: Incorporates a long-life cooling fan that operates at a quiet 35-45 dB level, effectively balancing essential heat dissipation with a peaceful environment.
- Modern Interface & Connectivity: Comes with a standard LCD interface with optional upgrade to a 4.3-inch capacitive touch display. Offers remote monitoring and control via Wi-Fi and APP, and supports wireless firmware upgrades for convenient future updates.
- Maintenance-Friendly Features: Includes a replaceable and washable dust-proof net with a cleaning cycle reminder, ensuring consistent cooling performance and simplifying maintenance.
