I've gone full DIY for my setup. My primary one is a hybrid on/off grid setup, with the on-grid part being that the inverter has a mains utility input for powering any devices plugged into it should there not be any panel activity and the batteries are drained. But, it doesn't feed back into the grid (important to not charge the grid wires if there's technicians working on it, but if power dies, I'm likely going to kill the main breaker regardless so I can use my inverter generator if I wanted, since that can also be used to charge the batteries and power stuff).
My inverter powers a few things with a total capacity of 30A that I have split between two 15A circuits, one in the house, and the other in the garage.
My panels are ground based, purchased secondhand for a steal, about $0.05/watt. About 3kw worth, probably going to add some more to safely max the input of the inverter. Battery backup is LiFePO4 batteries, about 15kwh worth. I'm aiming to get it up to 30kwh before summer really hits.
As of now, I can run a chest freezer for about 20 days without any sun, or the majority of my "high priority" stuff (NVR, local networking gear, etc) for about a week. Pretty happy with it. The most expensive single piece was the hybrid inverter. Even the PV combined box wasn't that bad of a deal, and made it easy to hook things up. I have a secondary setup that has about 1kw of panels, 3600Wh of battery capacity, and a 2kw inverter. That one is entirely off grid.
There's another prepping community here also. There's a bit of an overlap, sure. I think one is more about just news events, the other actually prepping.
Either way, answer is yes ๐คฃ
