Not true. It happens all the time. Every time a load is energized while the panels are producing in fact. With a meter you would see this. Maybe some folks don't use any power during the day. I sure do.
Is a meter necessary for a properly functioning system? No. One thing it would do is correct the misunderstanding of how the system works that many people seem to have.
BTW, solar amps are always equal to demand unless demand is greater than what solar can produce as battery charging is also just another load.
