About This Product

The Fronius 25kW VERTO PLUS 3 Phase Solar Inverter With SPD 1+2 is a three-phase solar inverter designed for larger residential, commercial and small industrial PV installations. It combines a 25 kW AC output with multiple MPPT tracking, giving installers flexibility when working with different roof orientations, array sections or module strings. The VERTO PLUS platform also supports battery integration, allowing the inverter to form part of a hybrid solar and storage system where compatible equipment is used. Integrated Type 1+2 surge protection provides additional DC-side protection as part of the inverter installation.

Who This Product Suits

The Fronius 25kW VERTO PLUS 3 Phase Solar Inverter With SPD 1+2 suits three-phase properties requiring a larger solar system with flexible string design. It is particularly useful for commercial buildings, workshops, warehouses, larger homes and sites where panels need to be divided across different orientations or array sections. The hybrid capability also makes it suitable for projects where battery storage is required now or is being considered as part of the overall system design. Final inverter sizing, battery compatibility and network approval should be confirmed by the system designer or installer.

Specifications Explained

This Fronius inverter provides 25 kW of three-phase AC output and uses four independent MPPT trackers, allowing separate PV sections to operate around their own optimum operating points. The VERTO PLUS is a hybrid inverter platform, providing the DC and control architecture required for compatible battery storage as well as conventional solar generation. It supports Fronius system monitoring and energy-management functions through the Fronius Solar.web ecosystem. Integrated Type 1+2 DC surge protection helps protect the PV input circuitry against surge events, while the inverter’s multi-MPPT design gives installers greater freedom when configuring complex commercial and multi-orientation arrays.

Summary

The Fronius 25kW VERTO PLUS 3 Phase Solar Inverter With SPD 1+2 is a 25 kW three-phase hybrid inverter aimed at larger and more complex solar installations. Four MPPT trackers, compatible battery integration, Fronius monitoring and integrated Type 1+2 surge protection make it a practical option where system design flexibility and future energy storage are important. As with any commercial-scale inverter, the final PV string arrangement, battery configuration and grid connection requirements should be checked against the project design before installation.

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.
