S227260 – Zero Export Energy Meter – EFR4002IP

The Ziehl EFR4002IP is a high-performance zero-export and feed-in control relay designed for managing photovoltaic systems where export limitation is required. It continuously monitors grid current using external current transformers and dynamically adjusts inverter output to prevent feed-in beyond the allowed threshold. With Ethernet connectivity, Modbus TCP support, and rapid reaction times, it integrates easily into modern PV installations. The EFR4002IP provides reliable, precise control to ensure grid compliance and stable system operation.
