Enphase IQ8 vs IQ7: Is it worth the upgrade?
Enphase, the maker of the most popular microinverters in the US solar market, announced that it will be releasing the latest version of the IQ series later in 2021. Product releases from Enphase are often a big deal, because microinverters and power optimizers now dominate the residential solar market, accounting for about 80% of all installations. New features from Enphase are good news for consumers, and also have the potential to move other inverter manufacturers to adopt those features to stay competitive.

Enphase vs SolarEdge: which home solar inverter is best?
When it comes to designing a home solar system, most people tend to focus on the panels, but arguably the most important component of the system is the inverter. The inverter does the important job of converting direct current (DC) power from the panels into alternating current (AC) power that your home can use. It’s a complex device, and manufacturers offer different designs with pros and cons that a homeowner should understand before they sign off on a proposal from a solar installer.

If you have a home solar system, it won’t keep your house powered in a blackout unless you have a battery system. This is because solar inverters have a feature called anti-islanding. A solar inverter converts direct current (DC) power from solar panels into alternating current (AC) that your home and electric grid use. AC power has a frequency of 60 hz in North America. In normal operation, your solar inverter “listens” for power from the grid, and synchronizes its AC output to that of the grid.
