Fronius Primo 3.8-1 3,800 Watt Grid-Tie Inverter
Fronius Primo 3.8-1 3,800 Watt Residential Solar Grid-Tie Inverter
Fronius Primo 3,800 Watt, non-isolated string solar grid-tie inverter.
For those of you looking for a step up from the Fronius Galvo series of inverters, the Primo series is what you want. The Fronius Primo line of inverters offers more power output and energy production than other inverters in their class while keeping its size and weight at a minimum due to its transformerless design. With an available range of power from 3,800 Watts to 8,200 Watts and a very wide range of accepted input voltages, they will meet the needs of most customers. Whether you want to offset a portion of your electricity usage, 100% of your usage, or produce enough energy to sell back to your utility company, the Fronius Primo inverters can do it all. They are designed for residential solar applications but can easily be installed for small commercial applications that use single phase utility service. They also leave you room to grow your system. The inverters can be combined in parallel by using the Fronius Solar Net input and output connections. This establishes a communications ring for the paralleled inverters which allows them to work together for increased total output capacity. This means that you can add additional Primo inverters at a later date. The Primo inverters are also "smart grid" ready. They come with advanced communication features that allow the inverter to better integrate and share performance data with your utility company. Over a 20 year period, the inverters will be able to keep up to date with smart grid technology via software updates and/or expansion cards. The Primo series is NEC 2014 compliant in addition to having built-in arc-fault circuit interrupt (AFCI) and ground fault detector interrupt (GFDI) capabilities. This means the inverter will not raise any issues with your local electrical inspector or utility company. It's fully compliant with all applicable regulations (see below for the full list). In addition, the Primo is Wi-Fi (802.11 b/g/n) and Ethernet ready out of the box and comes with free monitoring software that you can access from a computer or your smartphone.
