My upgrade is going to start a fire.
In the last couple weeks I upgraded my charge controller from a 20 amp to a 30 amp Eco flow 12/24v. Add 3 200 W biracial solar panels and add some 2/12 outdoor Romex. To replace the used extension that it's been using for several years. Now everything is acting up. The charge controller is overheating blacking out the screen. I keep trying to rearrange the setup parallel in series and individually and I can't fathom what changed to have such a drastic response. Or every combination gets nearly the same result.
Did I just over charge somewhere? I'm not sure I've moved that far from the micro-solar I've been using, but burning down the building isn't on the list.
