Is this the controller--it says here it does not have any LEDs.

Did you get the 24v version by mistake?
Connected to battery first and then connected to PV panel. Not using the load terminals - nothing connected there.
That product description is
WRONG. All SunSaver models have multi-color status LED and 3 battery state-of-charge LEDs. And no, don't have the '24v' model - see pics.
