The photovoltaic system with anti-backflow is that the electricity generated by the photovoltaic is only used by the local load and cannot be sent to the grid. When the PV inverter converts the DC point generated by the PV modules into AC power, there will be DC components and harmonics, three-phase current imbalance, and output power uncertainty.
If there are many such power generating sources to transmit electricity to the power grid, the power quality of the power grid will be seriously degraded. Therefore, this type of photovoltaic power generation system must be equipped with anti-reverse flow equipment to prevent the occurrence of reverse power.
In a photovoltaic (PV) system, the electricity generated is primarily used to power loads. When the generation exceeds the load demand, excess electricity flows back into the grid, creating a "reverse current." Grid regulations typically restrict unpermitted backflow, and unauthorized power feeding can result in penalties.
In the grid-connected two-way meter, the forward power is the power provided by the grid to the load, and the reverse power is the power delivered by the photovoltaic to the grid. The photovoltaic system with anti-backflow is that the electricity generated by the photovoltaic is only used by the local load and cannot be sent to the grid.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
