My Classic 250 switches rapidly from Bulk to Absorb and back about every 3-4 seconds. My battery voltage is at 24.3 V my float voltage setting is 27.2 the absorb is 28.6 which are the recommended voltage settings for a the two inline 12 V marine batteries I have. (EverStart 29DC) It does this...

I have another Classic 200, 24 V solar system. Unit is alternating between GOT COMM? and resting. It can see the voltage but displays 0 Amps. I did both a software and a hardware factory restore as per the manual, but the problem persists. Any ideas? Thank you.
