Maximum flexibility in system design is achieved with the inverters innovative SuperFlex Design. The characteristics of this inverter allow for a quick and easy install which can be carried out indoors or outdoors. Maintenance is user-friendly thanks to the SnapINverter mounting design. The Fronius Primo is one of the most communicative inverters available on the market, using WLAN or Ethernet it connects to the internet and allows system owners to monitor their system remotely.
The innovative hinged system design of this inverter offers a simple installation and servicing process for the user. The connection and power stage set compartments are installed separately with the connection compartment and the cables mounted to the wall first, followed by the power stage set compartment. This means when servicing the unit there is no need to detach the whole inverter; only the power stage set compartment needs to be removed, leaving cables, settings and configurations in place.
Integrated WLAN interface
Fronius have included simple data monitoring with this inverter with the WLAN interface. The inverter connects wirelessly and allows the user to monitor how the solar PV system is performing via the Fronius SolarWeb using an internet-ready device.
The innovative SuperFlex Design permits the inverter the ability to manage any difficulties that it may encounter alone, such as varying roof orientations, shading or if modules are added to the system at a later date. This is achieved with the SuperFlex technology which incorporates the system demands into a single inverter format. Maximum flexibility is guaranteed with high system voltage and wide input voltage range. All DC inputs and MPPTs are therefore able to accommodate the whole nominal output of the inverter, making this inverter suitable for any application.
Dynamic Peak Manager
Dynamic Peak Manager is a new MPPT algorithm that changes when searching for the peak operating point. The full characteristic curve routinely checks to find the global maximum power point (GMPP), even in partial shading.
Smart Grid Ready
Fronius have future-proofed their technology by equipping their inverters for the Smart Grid of the future. Advanced Grid features have been built into these inverters, these include control functions for optimum feed-in of reactive/effective power. This functionality allows for stable grid operation even in circumstances when the solar PV density is very high and yield losses can be a resulting factor. This helps ensure the return of your PV system.
