The SolaX X1 Mini G4 0.7kW Single Phase String Inverter is a refined choice for small-scale solar installations where performance and simplicity are key. Built for the latest generation of residential PV systems, it provides dependable single-phase power conversion with intelligent control and class-leading efficiency for British homes.
High-Efficiency Performance for British PV Systems
Delivering up to 97.1% peak efficiency, the X1 Mini G4 0.7kW maximises solar harvest from limited roof space. A wide 55–380V MPPT operating window and rapid tracking accuracy ensure consistent generation through low-light mornings, cloudy weather, or mixed-orientation panels common across UK housing. The low 70V start-up voltage allows generation to begin earlier each day, improving daily yield.
Built for Reliability & Protection
Encased within a robust IP65-rated shell, this inverter is purpose-built to withstand British weather. Fan-free natural cooling keeps noise below 25dB, making it perfect for external walls or internal plant rooms. Integrated surge protection, insulation monitoring, and residual-current safeguards maintain safe, long-term operation under G98 and EN 62109 compliance standards.
Key Features
- High conversion efficiency up to 97.1%
- Wide 55–380V MPPT range for improved low-light response
