Fronius Symo Advanced 20.0-3-M 20kW Three-Phase Grid-Tie Inverter with Arc Fault Detection & Dual MPPT

The Fronius Symo Advanced 20.0-3-M is a robust, high-efficiency 20kW three-phase grid-tied solar inverter with adaptive arc fault protection and flexible system design, engineered for high-yield commercial installations. 
Designed and manufactured in Austria, it combines proven SnapINverter architecture with advanced safety and intelligent performance features.

While not intended for standalone off-grid use, the Symo Advanced may be integrated into AC-coupled hybrid systems when supported by a compatible grid-forming inverter.

Intelligent safety with Fronius Arc Guard – adaptive protection for evolving PV environments

The integrated Fronius Arc Guard delivers real-time arc fault detection to prevent electrical fires before they start. Using a proprietary algorithm that continuously learns from field data, the system improves its detection accuracy over time—offering a forward-looking approach to photovoltaic safety. This feature ensures compliance with international standards and adds peace of mind to every installation.

Flexible performance with SuperFlex Design and Dynamic Peak Manager

Dual MPPTs and six DC inputs support complex array configurations with multiple orientations. Thanks to the SuperFlex Design, installers can confidently design systems with wide input voltage ranges (200–1000V) and high current handling (up to 51A combined). The Dynamic Peak Manager actively adapts to shading conditions, ensuring optimal energy harvest throughout the day without external components.

Main Features

20kW Three-Phase Output – Ideal for commercial and industrial solar systems.
Integrated Arc Fault Circuit Interrupter – Fronius Arc Guard with self-learning algorithm for smarter fault prevention.
Dual MPPTs – Flexible layout support for complex rooftops.
Wide Voltage Input Range – Operates from 200–1000V DC, suitable for diverse PV designs.

Important Disclaimer: Installation of Hardwired Electrical Products in Australia

Please read the following information, including the disclaimer at the bottom of this page;
by purchasing from Buzz Energy Systems, you understand and acknowledge these terms.
 

When it comes to the installation of hardwired electrical products in Australia, it is important to be aware of the regulations and guidelines in place to ensure safety and compliance.
As per the Electrical Safety Act, installations operating at ELV (Extra Low Voltage) levels of 120 VDC and below can be installed by individuals with the necessary knowledge and skills.

However, it is crucial to note that installations operating above ELV levels require the expertise of licensed electricians and experienced installers. Products falling under this category are not suitable for DIY (Do-It-Yourself) installation and must be handled by professionals. Attempting to install such products without the proper qualifications can not only compromise performance but also invalidate any manufacturer's warranties. 

At Buzz Energy Systems, we recognise the importance of reliable and efficient installations that prioritise safety, performance and warranty compliance. Our team consists of qualified tradespeople and specialists who are equipped with the expertise required to handle complex electrical installations.

For installations that operate above ELV levels, we strongly advise against DIY installation. Instead, we recommend seeking professional assistance from licensed electricians and experienced installers to ensure the proper installation and optimal performance of such products.

When it comes to installing hardwired electrical products above ELV levels, rest assured that Buzz Energy Systems can provide the necessary qualified tradespeople and specialists. Our professional installation services guarantee compliance with regulations, the preservation of manufacturers warranties and most importantly, your safety.

Do not compromise on the installation of your hardwired electrical products. Trust Buzz Energy Systems for a professional and hassle-free experience.
