6 FAQs about [Solar inverter grid access and backflow prevention]

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.

How do photovoltaic anti-backflow systems work?

According to different system voltage levels, photovoltaic anti-backflow systems can be divided into single-phase anti-backflow systems, three-phase and energy storage system ones. In a power system, power is generally sent from the grid to the load, which is called forward current.

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 to use a grid-tie solar inverter?

#1 Use RPR (relay power relay) to isolate the PV plant from the grid by means of tripping the breaker or releasing the contactor if there is any reverse power detected. #2 Use an Export limiter to limit the power generation of the grid-tie solar inverter concerning the power required by the load. #3 Use of PLC as an export limiter.

How does a DC-coupled solar & storage system work?

The sun hits the solar panels which in turn push energy through conduit through an inverter. In a DC-coupled Solar + Storage system, where a battery is installed in front of the inverter along with the PV, power can flow either directly to the grid through the inverter or to the battery where it can be stored and later discharged to the grid.

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.
