The Primo is one of the latest additions in the SnapINverter range. It boasts all the features of the range, including a 97.8% maximum efficiency, Wi-Fi connectivity, free monitoring via Solarweb, compatibility with the Fronius Smart Meter and an available extended warranty. The Primo is a single phase string inverter in the 3kW to 8kW models, making it a great choice for larger residential or small commercial systems on a single phase connection.

Doing the basics better

The Primo is one of the newest models in the SnapINverter range. It was met with instant demand when it arrived on the residential market in 2015, quickly becoming our most popular model. All the inverters in the SnapINverter range boasted high efficiencies, and the Primo was no exception with a maximum efficiency of 97.8%. Couple this with leading algorithms in the MPPT, which can only be developed from years of experience in the field, you get an inverter that extracts more kWh per kW than almost any other inverter on the market. The Dynamic Peak Manager also enables the inverter to generate more output with shaded systems than traditional string inverters. The reliability of the unit is surpassed by few in the field, making them an ideal choice in remote and fringe of grid areas where reliability is vital. With Fronius' service team in Australia and Solargain's extensive reach, you can be confident that even if something goes wrong, a replacement is days away, not months.


More than just an inverter

The SnapINverter generation has changed the way we interact with our inverters. With on-board Wi-Fi (or with the included LAN port), customers can easily connect the Primo to their network at home. This however is only part of the picture. Fronius' outstanding free web service, Solarweb, enables customers to see their production figures via the internet from anywhere in the world. Furthermore, free iPhone and Android apps make accessing this data a breeze. The open communication protocol and energy management function enables you to integrate easily to components from third party suppliers and optimise the self consumption of power. Finally, customers can prepare for battery storage by incorporating a Fronius Smart Meter into their system. This device will enable Solarweb to show you not only how much power you're producing, but how much you're using in the house - even in real-time. With the Fronius Smart Meter installed, you can switch on any device and watch your consumption change instantly. You can also view reports on how much power you've used, exported and imported from the grid. This is vital information for those considering batteries down the track. The new SnapINverter generation makes all this possible, and it's taking solar inverters to a whole new level.
