Erratic output MPPT 100/30 watts quickly fluctuating between 20w and 400w.

I have been having difficulty maintaining my system while for some reason my charge controller is not maintaining a steady energy stream. Solar panels are clean, functioning properly, in constant sun. This has also been effecting the 12v system as it has been below 11V

The insulation on your panels or wiring maybe? What battery do you have. If lead based maybe an internal issue? Like a collapsed plate? Or a connection that has worked loose.

It is trying to track but Something is disrupting the process.

Have you tried updating firmware?
