Advanced MPPT & High Power Density

Equipped with dual or triple MPPT configuration (model dependent), the SolaX X3-PRO G2 three-phase residential on-grid inverter supports flexible string design across multi-orientation rooftops. Built-in global MPP scan enhances real-time optimization, improving performance in partially shaded conditions.

Ultra-high power density reduces installation footprint while maintaining robust output capability. With recommended PV array power scaling up to 45.0 kWp (30kW model), the inverter supports large residential villas, commercial rooftops, and distributed C&I projects.

Intelligent Design & Smart Monitoring

The inverter integrates 24-hour monitoring via WiFi, LAN, or optional 4G connectivity, enabling remote diagnostics and performance tracking. Smart loads management allows integration with heat pumps and EV chargers, supporting modern residential energy ecosystems.

Built-in export power control ensures compliance in grid-restricted environments, while adjustable power factor (~1, 0.8 lagging to 0.8 leading) maintains stable synchronization with utility networks.

Safety, Protection & Compliance

The SolaX X3-PRO G2 three-phase residential on-grid inverter incorporates comprehensive protection architecture to enhance operational safety and reduce service risks:

• Type II Surge Protection on both DC and AC sides
• Active anti-islanding protection (frequency shift)
• DC reverse-polarity protection
• Residual current detection
• Optional AFCI support
• AC overcurrent & short-circuit protection

Certified to international standards including IEC/EN 62109-1/-2, EN50549, AS 4777.2, VDE4105, IEC 61727, IEC 62116, and IEC 61683, the inverter is suitable for deployment across multiple regulated markets.
