System overview
A zero export system is connected to the utility grid but is designed to ensure that no surplus energy is fed into it. All the energy generated is consumed on-site. Here, it is important that the PV inverter can regulate the generated power so that only so much energy is generated as is currently consumed and in total no energy is fed into the grid. Adding additional electrical loads (e.g., an electric vehicle) can increase the usable power of the PV system.

System configuration: Solution 1
If the inverter of your PV system cannot regulate the power, it must be replaced with a new inverter. Alternatively, you can upgrade your PV system by adding a Sunny Island ( > Solution 3: Retrofit a Battery-storage System for Self-consumption with Zero Export in Existing PV Systems).
The PV inverters listed below can regulate the power within the allowed time:
