Measuring the in and out current would be a better indication of whether or not it is working, rather than the appearance of the green LED. Loomberah weather and astronomy including live solar radiation intensity and UV + Gunagulla aquaponics, organic eggs and cherries

+1 on that.
One test is worth more than 1000 assumptions.

A simple clamp AC/DC clamp meter / multimeter combo is a very handy tool to eliminate a lot of guess work. Will show if you have any current flow to the battery in seconds. It doesn't need to be a super accurate calibrated unit.A basic unit to give you a rough idea of what's going on is fine.

Once you establish if it is or isn't flowing any current to the battery. If it isn't then you can work out why. I would place my bet on the voltage being too high as the others have mentioned. Take one panel offline and see if it works.
