One issue when the batteries drain all the way and the sun comes out the controller starts in the powered on position and can waste energy if you are not around to shut it off

Once connected it started charging right away

I will repeat something the instructions mention but should have been strongly highlighted you gtmustlt connect the battery first then the solar panel

If you dont the controller acts very strange and doesnt work right

Posted by a reviewer on Amazon

It wont power up the load terminals the power switch may or may not function it allows full solar panel voltage to charge the battery with no regulation whatsoever

Its very casually mentioned in small print with no warning

I also would not use this controller unless you run the load through it or run the load through some device that has a low voltage shut down
