I've seen at least two people posting in past week who are completely off-grid and losing all power because their non-tier 1 equipment has failed. Even with tier-1 equipment it is good to have a backup plan in place if you are 100% off grid and doubly so when you are using non-tier 1. You are your own utility company now and can't rely on somebody else to get your power back on.
Some suggestions:
1) Make sure you have plan if your main system dies
2) Have documentation on how to diagnose issues and everything well labeled if the technical person who knows the system may not be available. This is generally a good idea no matter what to do even for yourself. Will someone have to measure voltage? Will they know how to use a multimeter? Do they know where it is? What steps do they need to follow to diagnose why there is no power.
3) Have a backup inverter/charge controller/AIO. This may be a smaller version of what you have to at least run critical loads while the main system is down.
4) Verify you have spare fuses for critical components if applicable
5) Backup generator (either solar based or fossil fuel based).
6) Backup PV panels. Some people have extra PV panels stored away in case a storm takes out their currently installed/mounted panels. Minimum number to at least allow critical functionality of your system.
any others suggestions?
