I am assuming you mean that the controller will not go back into bulk the same day as it went into float but the next morning it again goes into bulk. This is exactly what it is supposed to do. The voltage is based on
battery charging requirements, not your house load. Once the controller goes into float for that charging cycle it should not go back into bulk until the voltage drops to a set threshold. Usually this is around 12.9v and normally occurs only after the sun gets low on the horizon or sets. Your
refrigeration load will run fine at float voltage but the
battery internal resistance is too high for any significant charge to flow into the battery. The
solar controller should provide enough amperage to handle the house load, assuming of course that there is sufficient
power available from the
panels. Most days my controller goes into float at about noon and amps into the battery fall off to less than one, but the controller is putting out 6-15 amps handling the house load which varies depending on what I'm running. On rare occasions when I get a couple of hours of heavy overcast during the day my battery voltage will dip below 12.9 and the controller will switch back into bulk when the sun comes back out. I don't think you have anything to worry about as I've seen my controller putting out 580 watts at 13.3 volts when under heavy house load while in float with less than an amp going into the batteries. If you are in float mode and your battery parameters are set properly on your controller then your batteries are fully charged and there is no reason for the controller to go into bulk mode. A house load will pull the battery voltage below float. The controller, again assuming enough
power is available from the
panels, will put out enough amperage to hold the programmed float voltage. That power does not go into your batteries but runs your house load.
