Hey everyone! I have a 12-panel Enphase solar system set up in California since 2020, but I recently realized it's not meeting my needs after getting a Bolt EV. I'm considering upgrading by either doing a totally new solar setup or just swapping my current 370 watt panels for new 550 watt ones. I'd love to get your thoughts. Would swapping the panels be straightforward, or do I need specialized knowledge for this? Is there any programming or extra steps involved?

Before you dive in, make sure you know the max wattage and voltage of your current IQ7+ microinverters. They might only support up to 440 watts, which means swapping to 550W panels could be a waste. You'd also want to check their performance to see if they're already clipping during peak sunny hours, as that could limit their output. Better to verify this first!
Have you looked into adding to your existing array instead of replacing what’s already there? Consider if there's a combiner for additional strings, that's often an easier route. Double-check how many strings they put in during initial installation!
Just swapping the panels might not do the trick. If your current setup is already maxed out with those IQ7+ inverters, you might need to upgrade to IQ8 models to handle the larger panels. Also, check with a certified Enphase installer to avoid wasting time and money on a poorly planned upgrade.
Totally agree! Even if it seems simple, a consultation could save you from making a mistake.
If you're feeling adventurous, I self-installed 104 panels and it was quite the project! It's doable, just be ready for some challenges. But if your current setup is recent and still working, have you thought about just adding new panels instead of swapping? That could be a simpler fix.
I think you’re right about the inverters! It’s definitely key to know their limits.
