Why choose it

This inverter stands out with its high efficiency—up to 98.2% maximum and 97.5% Euro efficiency—reducing energy losses and improving ROI. The built-in AFCI (Arc Fault Circuit Interrupter) enhances safety by detecting and mitigating arc faults, while the integrated DC switch allows safe isolation during maintenance. With dual MPPTs, it adapts to complex roof layouts or partial shading, maximizing energy harvest. Battery compatibility with the SolaX Triple Power series ensures future-ready storage integration for peak shaving or backup power.

Ideal use cases

• Commercial rooftop solar systems requiring three-phase power
• Agricultural operations with high daytime energy consumption
• Solar-plus-storage projects for self-consumption and backup
• Retrofitting existing PV systems with hybrid capabilities

Good to know

The inverter operates reliably in temperatures from -30°C to +60°C, making it suitable for diverse climates. Its IP65 rating protects against dust and water jets, allowing installation in semi-exposed locations. The included communication module (Wi-Fi/LAN) enables remote monitoring via the SolaX Cloud platform, while CT clamps ensure accurate grid feed-in management. For installers, the unit supports up to two DC inputs per MPPT, offering flexibility in string configuration.
