Ferrite filter products can help speed up digital devices by suppressing common mode current from RFI sources OR prevent digital devices from emitting RFI on its connecting cables and power supply lines.
Purpose. Simple, Effective RFI Kit consisting of 3 Solar Noise Filters (Mix 75) with 1/2" ID, for use on 3 Input/output ports such as Solar Panel Array input, Battery and Excess Load ports. Noise filters suppress noise and RFI at typical frequencies generated in solar charge controllers.
This kit is designed to choke common mode currents going into or exiting from your charge controller and they help keep common mode current out of the power line (or into your radio through the battery) which could cause interference to other devices connected to the same power line if not suppressed.
THE RFI KIT FILTERS ONLY SUPPRESS COMMON MODE CURRENT (SIGNALS) THAT ARE COMMON TO ALL WIRES IN THE CABLE, AND DOES NOT EFFECT INDIVIDUAL DIFFERENTIAL SIGNALS ON EACH WIRE. THE FILTERS HAVE NO EFFECT ON THE NORMAL SIGNALS CARRIED WITHIN THE CABLE.
If you use an inverter and experience RFI noise use additional mix 75 ferrite filters on the input and output of the inverter to help suppress this noise.Install both positive and negative wires through the same filter.
