A solid little unit that makes keeping track of our solar power much less of a chore.

Having the solar output on my phone is probably my favorite thing about this inverter—no more going outside just to check how the system is doing. It fits neatly into our rooftop setup, and there's no fan noise to listen to. The weather-resistant housing is reassuring for an outdoor installation, too.
