solar charging while plugged in problems

[Greg and Kathy]

yesterday while monitoring my viltron battery monitor I noticed that after the sun went down I was using battery power while plugged in. the fridge was running on AC so I know power was in from the house. during the day the solar and battery charger were powering at the same time and the solar pushed the battery up to 14.6volts. could that cause the built in battery charger to trip off. a simple unplug from the house and replug in turned the WFCO charger back on ant now running normally. will the higher solar charge voltage cause the battery charger to shut down and if so will it simply restart on its own when battery hits a certain voltage.
