SolaX X1-MINI G4 Single-Phase On-Grid Inverter Overview

The SolaX X1-MINI G4 single-phase on-grid inverter supports modern high-efficiency PV modules with up to 200% PV oversizing capability, enabling optimized DC/AC ratios and improved rooftop energy yield. With maximum conversion efficiency up to 98.0%, the inverter ensures stable output performance while maintaining compact dimensions suitable for residential wall-mounted installations.

• Power Range: 0.6kW – 3.3kW
• Maximum Efficiency: Up to 98.0%
• PV Oversizing: Up to 200%
• 16A PV Input Current supporting high-power modules
• Ultra-wide MPPT Voltage Range with global MPP scan

Advanced MPPT & Energy Optimization

The integrated MPPT algorithm enhances energy capture under varying irradiance and partial shading conditions. With global MPP scan functionality, the inverter dynamically tracks optimal operating points to maximize annual system yield. This makes it particularly suitable for residential rooftops with complex orientations.

The SolaX X1-MINI G4 single-phase on-grid inverter maintains stable voltage regulation across a wide operating range, ensuring compatibility with modern mono-crystalline PV modules and supporting consistent long-term energy production.

Installer-Focused Engineering

Weighing approximately 5.2–5.5 kg, the inverter is lightweight and easy to mount, reducing installation time and on-site labor requirements. The fanless natural cooling design minimizes moving components, lowering maintenance risks and improving long-term operational reliability.

IP66 ingress protection allows safe outdoor installation in demanding environmental conditions. Parallel operation capability (up to five units without external EMS) enables flexible residential expansion and standardized deployment across housing projects.

Smart Monitoring & Grid Integration

The SolaX X1-MINI G4 single-phase on-grid inverter integrates with SolaXCloud monitoring, offering real-time performance tracking and IV curve diagnostics. Installers benefit from improved commissioning accuracy and remote visibility for ongoing system management.

Built-in export power control supports compliance with grid-limited installations, while compatibility with EV chargers and heat pumps enhances residential energy integration.

Safety & Compliance Architecture

Engineered to meet international grid standards, the inverter incorporates multiple protective mechanisms:

• Type II Surge Protection on AC & DC sides
• Active anti-islanding protection
• Rapid shutdown readiness
• Optional AFCI support
