Many of today’s three-phase string inverters for commercial rooftop and carport systems have rated outputs in the range of 30-100 kW-AC. For DC arrays that are only 10-25 kW, this can lead to wasted inverter power. With larger inverters on crowded, complicated rooftops, PV systems could end up with fragmented arrays. Not a problem here! Because the Symo Advanced inverters range from 10 to 24 kW and come in 208V to 480V AC service types, installers have the flexibility to accommodate smaller three-phase rooftop projects and challenging design spaces for larger systems.
APsmart announces Fronius as the newest addition to its list of inverter manufacturers under its Photovoltaic Rapid Shutdown Systems (PVRSS) certification to the UL 1741 standard. The CSA has certified all six Fronius Symo Advanced models to be used with APsmart’s module level shutdown solutions.
For systems where NEC 2014 cannot be achieved, the Symo Advanced and APSmart partnership is the best solution.Press Release on NEC listing with APSmart

The commercial and industrial (C&I) space is one of the most challenging environments for solar installations. High ambient temperatures, high irradiance, obstructions, setbacks or pathways add to the complexity and cost of design, installation and operation & maintenance (O&M). However, the right inverter choice will help to overcome these challenges.
The Fronius Rooftop Package provides a comprehensive solution for commercial rooftops. The package centers around the lightweight Fronius Symo Advanced 24.0, the Fronius Shade cover and Fronius MC4 connectors. The combination of these 3 products creates a flexible, durable and easy to install system.
The lightweight Fronius Symo Advanced 24.0 inverter allows for mounting at any angle from vertical to completely flat. The 24 kW size facilitates both optimal inverter distribution and string length for space limited commercial roof tops. Simply connect the DC wires through MC4 connectors and eliminate multiple installation steps, such as wire management inside the inverter, installation and sealing of conduits, or pull tests of torqued conductors. Using a Fronius Shade Cover allows you to place the inverter in direct sunlight, or directly next to the array.
The collective design approach of the solution applies to both inverter and system design to provide a high reliability, right features, and right size, resulting in best return on investment for both installers and system owners. Low labor requirements, design flexibility, and the Fronius O&M advantages of this truly field serviceable inverter combine to provide best Levelized Cost of Energy (LCOE).
All Fronius Symo Advanced inverters have an integrated Power Line Communications (PLC) transmitter that is certified to the SunSpec Communication Signal for Rapid Shutdown. This open industry standard reduces installation and interconnection costs with Plug-and-Play system components from various vendors – allowing for customer choice and interoperability.
» As a string inverter leader we are striving for rooftop excellence and with the Fronius Rooftop Solution we take our offering for commercial rooftops even further. Customers have always asked for cost-effective installation options and a low-cost solution to protect the inverter from heat when installed next to the array. With the Fronius Rooftop Solution we provide a comprehensive solution for commercial rooftop applications while maintaining our high quality expectations. «Chris Connell, Head of Solutions Management
Three-phase power is a three wire Alternating Current (AC) power circuit. Most US commercial buildings use a three-phase 4 Wire 208Y/120V power arrangement because of its power density and flexibility. Compared to single-phase, a three-phase power arrangement provides 1.732 (the square root of 3) times more power with the same current and provides (7) power circuits. *The reason why this voltage configuration remains the most popular in North America is because of its flexibility in handling different load capacities.
The Commercial and Industrial (C&I) space are both complex and environmentally demanding for solar installations. High ambient temperatures, high irradiance, obstructions, etc. So what's the best way to overcome them? This article sheds light on these challenges and lays out solutions. Hint: the inverter plays a key role in this!
