Hey everyone, I'm on the hunt for a solar inverter that supports a 240 volt input and can handle 1000 volt DC strings. Unfortunately, my solar installer hasn't been able to track one down. Any suggestions or advice would be super helpful!

You could consider splitting your array to get 500V by running them in parallel and doubling your amperage instead. It might be a more feasible solution!
I’m not really familiar with all this—I’m just relaying what my solar guy mentioned. I’d love to learn more if you’re willing to share!.
Switching from 500V to 1000V can ramp up costs by about 30%, plus you’ll run into more regulations and safety measures. Not many options out there for residential setups, so don’t expect to find them easily online.
For North America, I’d recommend looking for inverters designed for "split-phase grid-tie" systems if you're trying to keep it under 600V. You definitely want to stick with residential inverters unless you’re okay with the higher complexity and costs of 1000V DC systems.
Just a heads up, panels rated for 1000V are typically commercial-grade. Make sure your panels are up to the task before proceeding!
Just curious, can we exchange numbers to talk more about it? If that's allowed, of course! ?
