About This Product

The Fronius 15kW VERTO PLUS 3 Phase Solar Inverter With SPD 1+2 is a 15 kW three-phase hybrid inverter designed for larger residential, commercial, agricultural and other three-phase solar installations. It combines three independent MPPTs with a dedicated high-voltage battery connection, allowing solar generation and compatible battery storage to be managed through the one Fronius platform. The inverter provides six PV string connections across its three MPPTs and supports up to 22.5 kWp of connected PV array capacity. Integrated DC Type 1+2 surge protection, AC Type 2 surge protection and arc-fault protection provide important electrical protection within the inverter.

Who This Product Suits

The Fronius VERTO PLUS 15.0 is suited to three-phase properties requiring a higher-capacity solar inverter with provision for battery storage. Its three MPPTs are useful on installations with multiple roof orientations, separate arrays or differing string conditions. It is particularly applicable to larger homes, workshops, farms, apartment buildings and small-to-medium commercial sites where a 15 kW three-phase hybrid inverter is appropriate. The Fronius battery interface and Full Backup capability also make it suitable for installations designed around compatible battery storage and backup power.

Specifications Explained

The VERTO PLUS 15.0 has a 15 kW nominal AC output and supports a maximum PV generator capacity of 22.5 kWp. Its three MPPTs each accept two DC string connections and operate across a 150-870 V MPPT range, with a maximum DC input voltage of 1,000 V. Each MPPT supports up to 28 A usable input current, making the inverter suitable for modern higher-current PV modules when strings are correctly designed. The battery input operates from 150-700 V DC. Maximum PV-to-grid efficiency is approximately 98%, while the IP66 protection rating allows appropriate indoor or outdoor installation. Full Backup functionality is supported when the inverter is installed with the required compatible battery and backup equipment.

Summary

The Fronius VERTO PLUS 15.0 combines a 15 kW three-phase output, three MPPTs, six PV string connections and a high-voltage battery interface in a single hybrid inverter. With Fronius Dynamic Peak Manager, integrated surge protection, arc-fault protection, IP66 construction and support for Full Backup, it provides installers with a flexible platform for larger three-phase solar and battery systems. It is a practical Fronius option where multiple PV orientations, battery integration and future energy management are part of the system design.

Further Information From The Manufacturer

Designed specifically for small businesses and larger single and multi-family homes, this powerful inverter offers maximum flexibility in system design. Whether it’s large PV systems for single-family homes with battery storage or complex roof structures with different module orientations, inclinations, module types or shading, the Fronius
Verto Plus handles it all with ease.

Thanks to the inverter’s hybrid capability, the Fronius Verto Plus can fully supply a home or building in backup power mode with up to 33.3 kW of three-phase power.
The Fronius Verto Plus guarantees the highest safety standards with an integrated SPD type 2 on the AC side and a SPD type 1+2 on the DC side. In addition, Fronius Arc Guard (AFCI) is factory-integrated into the inverter to protect the PV system from arc faults. With our servers and cloud storage located in Europe, personal data is
always optimally protected with Fronius.
