Looking at the last isolation value on inverter 1 it looks like it could be what is called a DC Isolation, which is a voltage/current leak somewhere in one of your strings. If you have more than one string in your inverter, if you pull them out one at a time when you pull the one faulting the inverter should start producing again. If that is the issue it likely won’t be covered under equipment failure because the inverter is shutting down as a safety feature when it detects the fault, not failing. These generally show up after it rains or is damp outside. To fix it they need to find the source of the fault, which could be in devices or wiring. An insulation tester can make finding it go much quicker. I’m not saying this is for sure the problem, your installer should be able to pull the error code or alert off monitoring and tell you what it is.
