The 8kW Single-Phase Off-Grid Solar Inverter from HuiJue Group is an ideal solution for off-grid power systems, delivering high performance and reliability for residential and small commercial applications. This inverter efficiently converts solar energy into usable electricity, providing off-grid energy independence while supporting energy storage for backup power. Its compact and durable design ensures a reliable and efficient power supply, even in remote locations.
Engineered for High-Capacity Solar Independence
This inverter is more than a simple power converter; it's the core of a high-performance, self-sufficient energy system designed for scenarios where grid power is unavailable, unreliable, or too expensive to connect.
- High-Power Solar Harvesting: Features dual independent MPPT charge controllers, allowing you to connect two separate solar arrays (up to 5.4kW each) for a total of 10.8kW PV input. This maximizes energy yield from different roof orientations or panel types.
- Intelligent Dual-Charging: Can charge batteries simultaneously from both solar power and an AC source (like a generator), with a total charging current of up to 160A. This ensures your batteries are quickly replenished, no matter the weather or time of day.
- Pure Sine Wave Reliability: Generates utility-grade, pure sine wave AC output. This guarantees safe and efficient operation of sensitive electronics, including computers, medical equipment, variable-speed motors, and kitchen appliances, without risk of damage or noise.
- Flexible Operation Modes: Supports pure off-grid applications and can also be configured for grid-interactive use where available, offering versatility for various installation scenarios and future needs.
Key Features and Advantages
1. Unmatched Power and Charging Capacity
Built to support substantial energy needs without compromise.
- High Continuous Output: Delivers a steady 8200W (8.2kW) of AC power, capable of running multiple high-wattage appliances, power tools, and systems simultaneously.
- Massive Solar Charging: A 160A maximum solar charging current is among the highest in its class, enabling the use of very large solar arrays to charge battery banks quickly and efficiently.
- Wide Voltage Compatibility: With an MPPT voltage range of 90-450VDC, it is compatible with both standard and high-voltage solar panel strings, offering greater design flexibility and efficiency.
2. Smart Management and User Control
Stay connected and in command of your energy system from anywhere.
- Comprehensive Remote Monitoring: Built-in support for Wi-Fi and GPRS connectivity allows you to monitor system performance, battery status, and energy production in real-time via iOS or Android apps.
- Advanced Battery Protection: Features intelligent charging algorithms that optimize battery charging cycles, helping to extend the lifespan of both lithium and lead-acid batteries.
- User-Friendly Interface: Equipped with an e-touch button and one-click recovery function for easy, intuitive operation and troubleshooting.
3. Robust and Durable Construction
Designed to perform reliably in challenging environments.
- Built for Harsh Conditions: Features a built-in dust-proof kit and dual cooling channels to ensure stable, long-term operation in dusty or humid environments.
- Wide Temperature Range: Operates reliably in ambient temperatures from -10°C to 50°C, making it suitable for installation in unheated garages, sheds, or utility rooms.
- Compact & Efficient Design: Despite its high power, it maintains a relatively compact footprint with a DC-AC conversion efficiency of 90%, minimizing energy loss.
