Fronius Galvo 3.1-1 3,100 Watt Residential Solar Grid-Tie Inverter

Fronius Galvo 3,100 Watt, isolated string solar grid-tie inverter.

The Fronius Galvo inverters are perfect for small to mid-size grid-tie solar applications and available in a range of output power from 1,500 VA up to 3,100 VA. If you want to start out with a small system while having the ability to increase capacity at a later date, the Galvo series has you covered. 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. The Galvo inverters are also "smart grid" ready. This means 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 Galvo 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 Galvo 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.
