To prevent problems related to backflow, modern inverter and systems are equipped with a reverse current protection function. This function ensures that electricity flows only in the desired direction, i.e. from the solar panels to the load or grid, preventing any reverse flow.How does an anti-backflow inverter work?If any energy feeding into the grid is detected, the anti-backflow device immediately provides feedback to the inverter. The inverter then quickly reduces its output power, achieving a state of zero feeding to the grid. This function is critical for maintaining the safety and compliance of PV systems in regions with strict regulations.
What is a reverse current & backflow function?When a PV system generates more electricity than the local load consumes, the excess power flows onto the grid. This reverse flow of energy, originating from PV modules → inverter → load → grid, is referred to as reverse current or backflow. The anti-backflow function is specifically designed to prevent this reverse energy flow.
How does a Deye inverter anti-backflow work?4. The solution? Deye inverter anti-backflow working principle: install an meter with CT or current sensor at the grid-connected point. When it detects that there is current flowing to the grid, it will feed back to the inverter, and the inverter will immediately change its working mode and track from the maximum power point of MPPT.
How does anti-backflow work?If the generation exceeds the consumption, the surplus electricity flows back into the grid, creating backflow. Systems with anti-backflow functionality can adjust the inverter's output to ensure that the electricity generated is fully consumed by local loads, preventing excess power from entering the grid. Why Install Anti-Backflow?.
Does a photovoltaic system have anti-backflow?The photovoltaic system with CT (Current Transformer) has anti-backflow function, which means that the electricity generated by photovoltaics is only supplied to loads, preventing excess electricity from being sent to the grid. 2.
