My MPPT 100/50 has been in use since a year. The voltage output in bulk - measured at the terminal on the charger - is constantly low. During the day the voltage rises slowly from, say, 12,4 to 13.6V while it should be a constant 14.3V or Thereabouts while in bulk. The panels deliver anywhere between 70-95 Volts. It seldom reaches absorption, let alone float.
Q: should the voltage in bulk be a constant ~14,3? Can unit be defective? (Manual says 14.3V in bulk...?)
Q: how can I adjust the settings so the output goes up to ~14.3 instead of <~13.5V
