there's a better way.. Use an electrical branch between the root combiner and the blocker trigger, the low end of the electrical branch gets connected to the trigger and the high end gets connected to the power storage/battery. When the sun sets the lo end of the EB will lose power before the high end does and it will trigger the on or off respectively that way you always have power flowing and your lights turn on right as the sun sets and off when it rises and you're not wasting solar panels just for a switch
