A hot tip, when checking battery and panel condition, (if your charge controller doesn't have a battery backup), be sure to reset your charge perameters otherwise when you're done or they revert to Default which in my case was a maximum input charge of 13.8 volts at max of 3 amps.
Was wondering these past few weeks why my batteries were lower than normal, then it hit me, yep, I forgot to reset the charge controller, now it's set to 15 volts and pushing 20 amps rather than 3, even did an equalize yesterday too boot!

Quoting: groingo now it's set to 15 volts
Curious here... a 12 volt system? 15 volts?
For what set point? Absorb, float, EQ?

It's all automatic and just limits the max input voltage to 15 volts rather than 13.8.

15v at 20 amps is how to charge a battery. equalization is essential.
boy. good thing you caught that.

Well you have me confused, all the CC I am familair with do not have limits you set for voltage input, only the voltage to battery outputs. G/L

This one does, it's my backup Renogy $29.00 special 30 amp with led readout PWM CC, lets you set both upper and lower charge perameters.
