I'm working on a DIY solar project that has been going really well. I've got my solar panels set up and I'm looking to boost my generation capacity up to 3kW from around 800W currently, alongside 2.7kWh of battery storage. I'm currently using this system to power my workshop and charge tool batteries, but I'm generating way more power than I need for that.
What I'm hoping to do is connect my workshop's solar power system to my home's electrical panel so that the excess power can offset my home energy usage since the two are located close to each other. I've read online that I can use an inverter to tie my system directly to the electrical panel, as long as I have the proper safety interlocks in place. My plan is to augment my house's energy use with this setup and rely on the grid when solar isn't available.
Does anyone have advice on which inverter would be best suited for this that will allow for safe integration with my home system without risking the safety of line workers or causing any damage? Any suggestions or pointers would be greatly appreciated!

This is definitely more of a legal question than a technical one! You have to check the regulations in your area because in states like Utah and most of Europe, it's usually legal to tie in solar up to a certain wattage. In Massachusetts, where you're at, the rules will apply as well, so just make sure to look into that. Ultimately, grid-tie inverters will automatically shut off if the grid goes down, which helps with safety.
Yeah, definitely check your local laws. Better to be safe than sorry!
