There is an r/solar, they would probably have some ideas.

If you want to replace your inverter with another brand, check the specs on yours and what it is doing-is it a grid tie, off the grid, or hybrid system. That will allow you to comparison shop.

You talk about frequent resets. Is there any kind of visual alert or audible alarm when the inverter is down? Can you check your system for an alarm weekly? Can you reset it yourself safely? Safely will be a version of disconnecting load before restoring power to the device. I read that some inverters for solar are sensitive to fluctuations (bumps) in utility power. Maybe a setting needs to be adjusted, or maybe it’s as good as it gets and you have to check it after any outages.
