High-Efficiency Solar Power Conversion for Two Panels

The Sigenergy SigenMicro 768 US provides an efficient solution for residential solar installations using module-level power electronics.

Unlike a traditional string inverter that manages multiple panels together, the SigenMicro converts solar energy into AC electricity directly at the module level.

Each SigenMicro 768 connects to two compatible solar panels, reducing the number of microinverters needed for a given array while maintaining independent performance tracking for each module.

With up to 768W of continuous AC output, the microinverter is designed to work with modern solar panels and deliver reliable energy production throughout changing sunlight conditions.

Its compact design, outdoor-rated enclosure, and integrated communication capabilities make it well suited for residential rooftop solar installations and other compatible grid-connected applications.

Dual MPPT for Independent Solar Panel Optimization

The SigenMicro 768 features two independent maximum power point trackers, allowing each connected solar panel to operate at its own optimal electrical conditions.

Dual MPPT Benefits

• Individual panel optimization: Each solar module is tracked independently.
• Improved performance under variable sunlight: Helps manage differences in solar panel production.
• Flexible array design: Supports compatible modules installed in different orientations.
• Reduced mismatch losses: Limits the impact of differences between connected panels.
• Module-level visibility: Monitor individual solar panel performance.

Independent MPPT tracking is particularly useful for residential solar arrays where roof angles, shading, or panel operating conditions may vary.

Built-In WLAN Mesh Communication

The Sigenergy SigenMicro series features integrated WLAN Mesh communication technology designed to simplify monitoring and system connectivity.

Microinverters communicate through a wireless mesh network, creating a scalable communication architecture for larger solar arrays.

Smart Monitoring Features

• WLAN Mesh networking: Supports wireless communication between microinverters.
• Integrated energy management: Designed to eliminate the need for a separate network gateway.
• Module-level monitoring: Track performance of individual connected solar panels.
• Intelligent system commissioning: Supports streamlined setup through Sigenergy's monitoring platform.
• AI-assisted layout recognition: Helps identify connected module locations during system setup.
• Whitelisting security: Provides additional communication and system access protection.

These features provide installers and homeowners with detailed visibility into solar production and system performance.
