Bend if you bypass the controller by connecting the battery to be charged leads directly to the panel (no controller) it will give you the best charging power that can be offered. The controller will see this as being "sundown" or a fogbank rolling in and it could care less.
Leave everything connected "as is" and connect those intercept-at-the-pass battery charging wires. You're going to disconnect as sundown anyway so what the heck. Keep it simple.
