Enphase EPCOS Ferrite ring torroid core, 50mm

When installing a power line filter with an Enphase Microinverter System, follow these requirements:

• Separate the Envoy and the microinverters from other site loads
• Install the ferrite toroid rings between the PV sub panel to the main AC panel. If there is no sub panel, install the toroid rings on the noisy circuit.
• If there is no sub panel, install the toroid rings on the noisy circuit.

There are three methods of use:

• Method 1: Pass the conductors (exclude neutral and ground) through the toroid
• Method 2: For use on sites with high levels of power line noise. Using three toroid rings, loop the phase line conductors (exclude neutral and ground) through the toroid rings.
• Method 3: Only recommended for limited space. Using one toroid ring, loop the phase line conductors (exclude neutral and ground) through the toroid ring.
