A1solarstore was very helpful along the way. Me and my wife used the solar calculator to size a system and picked this inverter. Highly recommend

This inverter is quite small, but it does its job. I found it very convenient for my needs: I can watch the performance of my system wherever I want. Feels good to go solar.

We’ve bought this inverter along with the panels (Canadian Solar). Our system is small, and this Sunny Boy fits it well. The shipment was fast and so far our solar project is going great.

Is SMA Sunny Boy Inverter 3.8kw SB-3.8-1SP-US-41 suitable for off-grid installation? The type is listed as grid-tie inverter, but it also mentions both grid-tied and off-grid
