Zero Export Device EFR4001IP

Relay for energy flow EFR4001IP by Ziehl

The EFR4001IP power flow relay monitors the flow of power between the consumer and the public power at the grid connection point. The ERF4001IP now allows an increase of two-thirds of the generation power than the grid connection allows, when the overbuilt power is consumed and not supplied to the public power grid. Monitoring ensures the stability of the system.

• Convenient operation via built-in web server or LCD plain text display
• Control of heat pumps (SG-ready)
