The inverter is the piece of equipment that takes the high DC voltage from your solar system and converts it to 240 volts AC that can be fed into your house or back to the grid. It’s arguably the most important piece of equipment for reliability of a solar system. We have chosen to use only extremely reliable inverters. All of the inverters have WiFi capability so you can monitor your solar system power production from a computer or phone application.

ENPHASE are a Californian based company founded in 2007 that produce arguably the world’s most well-known microinverter. All solar power needs to be converted from DC to AC, this is typically done with one single large inverter mounted on your wall and this connects to your meter box. ENPHASE microinverters instead mount under each panel and convert the power directly to AC at the panel, the cables then run through their smart monitoring system named the Envoy and feed to your meter. This has the benefit of being able to monitor each panel individually, no bulky inverter required on a wall and shading affects only the panel it hits rather than the entire string. They can be considerably more efficient if there is shading hitting your roof at various times during the day. They are a high end solution that attracts a similarly high price tag.
