Battery Max Voltage

What is your configuration now?

Is it a 200ah panel to the Raggie / Juka float-only controller, along with those 60w worth of 3 total smaller panels going to the Steca 5A, and now both controllers connected to the battery?

I suppose that helps, and it is obvious that a 200w panel will fry the 5A Steca. If you can find a larger amperage Steca to handle your 200w of panel, preferably more, that would be the best thing to do.

If you are relying on the short-term overload capability of the Steca 5A to handle your 200w of panel, that will eventually fry.

Hi, Right now it's only the 200w panels connected to the Raggie controller, now if I add the 3 20w panels using different cabling and a separate controller (Steca 5A) will that harm the battery (having two controllers feeding it)??

It will only harm the battery if the two panels, both at maximum output during Bulk stage can feed more current to the battery than it can handle.
If the Amp-hour rating (C₂₀) of the battery is 100AH and it is Flooded Lead Acid, then the maximum current should be C/8 = 12.5A.
If your panels combined cannot support a higher current then there will be no problem.
