As battery temperature fluctuates, charging voltage needs to be adjusted to keep the batteries as healthy as possible. As temperatures rise, charging voltage is decreased. As temperatures fall, charging voltage is increased. All Morningstar controllers have factory default charging setpoints based on 25C. Batteries with temperatures that deviate from 25C regularly should have temperature compensated charging.
