FAQ About Anti-backflow
Q: What is PV anti-backflow? A: In a PV system, when the generated power is greater than the user-side demand – meaning the load is unable to consume all the energy produced – the excess power flows to the grid. Since this current flows in the opposite direction to the conventional one, it is referred to as "countercurrent."
