I'm currently installing a backup generator, specifically a used 20kw one with a transfer switch. I've got a main disconnect set up right after the meter and I'm keeping it all outside the house. Power will run through the transfer switch into the crawlspace and then to my main panel, which is in my office.
I'm really interested in solar power too, but I have a lot to learn about it. Even though it's more expensive than I'd like, I know it would be a great investment. I'm not looking to go completely off-grid but might consider it in the future. My question is: how can I set up my generator installation to make it easier to integrate solar later on? I'd rather not redo work if I can avoid it!

Why not think about using a hybrid inverter that accepts generator input? This way, with a small battery setup, you'd have a UPS system and still use your solar during outages. A hybrid inverter can function as a generator ATS, which could save you the hassle of reworking anything later if you do go solar.
I wouldn't rush into solar until you have a good amount saved up. I've seen others cobble together a system only to realize it doesn't meet their needs, leading to wasted money. The GridBoss videos from EG4 and Signature Solar are great for understanding what you really need before diving in. It’s better to invest that time and money wisely!
I totally get that! I want to start with a solid setup too, aiming for at least 10kw when I do it. My property is a bit hectic right now, so I just want to wait until I can do it right.
From what I've read, you should be careful about how you connect solar and your generator. Typically, solar should be connected between your Automatic Transfer Switch (ATS) and the meter pan. If it's connected after the ATS, the solar setup could malfunction when it detects the generator power, which could cause issues. There are solar systems that can handle generator input, but they're less common. You might also consider adding a battery system to handle low production times, as some setups can trigger the generator when batteries are low. Just keep these things in mind for future solar integration!
Good point! I think I'll try to leave enough room between my meter and main panel just in case I need to make changes later on. Thanks for the heads up!
Yeah, definitely plan for that now instead of later. It feels like a lot of work, but putting the right components in place will save you time!
That sounds interesting! I already have the ATS though, and money's tight right now. I might not be able to go solar until a few years from now. But hopefully switching to a hybrid inverter won't be too complicated when I get there!
