Are there any obvious physical degradations to look for or specific tests that can show issues? I don\u2019t have a megger but have two systems installed in grid tied systems and a couple off-grid.

I discovered this after convincing the owners to upgrade the inverters from old SMA\u2019s which don\u2019t test for it.
