About This Product

The Fronius 20kW VERTO PLUS 3 Phase Solar Inverter With SPD 1+2 is a 20 kW three-phase hybrid inverter designed for larger residential, commercial and light-industrial solar installations. It combines three independent MPPT trackers with a dedicated high-voltage battery connection, allowing the inverter to manage solar generation, battery storage and three-phase AC supply within one system. The inverter supports up to 30 kWp of connected PV array capacity and includes integrated DC Type 1+2 surge protection along with AC Type 2 surge protection. Fronius also provides integrated monitoring and communications through WLAN, Ethernet and industry-standard interfaces.

Who This Product Suits

The Fronius VERTO PLUS 20.0 suits larger three-phase properties where the solar system needs more capacity and flexibility than a typical residential inverter. Its three MPPT trackers are useful on installations with multiple roof orientations, different string layouts or separate PV arrays. The dedicated battery input also makes it suitable for projects where energy storage is being installed immediately or incorporated as part of the system design. For installers working on larger homes, workshops, farms and commercial premises, the Fronius design provides flexible PV string configuration while keeping solar and battery management within the same inverter platform.

Specifications Explained

The Fronius VERTO PLUS 20.0 provides 20 kW nominal three-phase AC output and accepts up to 30 kWp of PV array capacity. Three independent MPPT trackers operate across a 150-870 V DC MPPT range, with up to 28 A usable input current available per MPPT. A separate battery connection operates across 150-700 V DC and supports compatible high-voltage battery systems. Maximum efficiency is rated at 98.15%, while MPPT adaptation efficiency is greater than 99.9%. Protection features include integrated DC isolation, reverse-polarity protection, residual-current monitoring, DC insulation monitoring, Arc Guard arc-fault detection, DC Type 1+2 surge protection and AC Type 2 surge protection. Communications include WLAN, Ethernet, RS485 and support for Fronius Solar.web, Modbus TCP SunSpec and Modbus RTU SunSpec.

Summary

The Fronius VERTO PLUS 20.0 is a capable three-phase hybrid inverter for larger solar and battery installations. Its 20 kW AC output, 30 kWp maximum PV array capacity, three MPPT trackers and high-voltage battery connection give installers considerable flexibility when designing systems with multiple arrays or future energy-storage requirements. Integrated SPD 1+2 DC surge protection, monitoring, communications and electrical protection functions also reduce the number of separate components required around the inverter. For appropriately designed three-phase installations, the Fronius VERTO PLUS provides a practical platform for combining larger PV arrays with battery storage and energy management.

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.
