Product's Details

*Ultra-High Conversion Efficiency: With a maximum efficiency of 98.8% and European efficiency of 98.0%, it is 1.5% higher than the industry average. For a 5kW system, the annual power generation can be increased by about 1200kWh, significantly improving power generation benefits.

*Multi-Channel Independent MPPT: Supports 1–12 independent MPPT trackers with a voltage range of 120–1000V DC. It adapts to complex roofs with multi-orientation and shading, increases power generation by 5%–10%, and is compatible with a full range of PV modules.

*Full-Scenario Intelligent Adaptation: Supports free switching between grid-tied, off-grid, and hybrid modes, with a UPS zero-interruption switching time of less than 10ms. It adapts to residential, commercial, and power station scenarios and is compatible with 48V–384V energy storage batteries.

*Ultimate Safety Protection: Built-in 12 intelligent protection mechanisms, including anti-islanding, over-voltage, under-voltage, over-frequency, under-frequency, over-temperature, short circuit, leakage, and polarity reverse protection. The response time is less than 2s, and the protection grade reaches IP65, enabling stable outdoor operation all day.
* Remote Intelligent Monitoring: Supports WiFi, Ethernet, 4G, and RS485 communication interfaces. With an exclusive APP and cloud platform, it realizes 1-minute data upload, remote on/off, power adjustment, and firmware upgrade, improving operation and maintenance efficiency by 80%.

*The rated power can be customized to 1kW, 2kW, 3kW, 5kW, 10kW, 15kW, 20kW, 30kW, 50kW, covering single-phase and three-phase models; three optional MPPT voltage ranges are available.

*Intelligent MPPT Tracking Technology: Adopts the third-generation digital MPPT algorithm with a tracking accuracy of 99.9%, which can quickly respond to light changes and maintain efficient power generation in cloudy and weak light environments in the morning and evening. It is fully compatible with monocrystalline, polycrystalline, bifacial and other types of PV panels.

*Flexible Multi-Mode Operation: In grid-tied mode, it prioritizes feeding power to the grid and supports grid dispatching and power factor adjustment; in off-grid mode, it automatically switches when the grid is powered off and continuously supplies power to residential or commercial loads; in hybrid mode, it combines with energy storage batteries to realize peak-valley arbitrage and backup power supply, maximizing the self-consumption rate.
