Solar Charge Controller RFI Kit - 3 I/O PortsProduct DetailsPurpose. 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.

Christmas lights or yard lights with switching DC power supplies are often the RFI source and a clamp on ferrite bead on the AC AND the DC side feeding the lights is needed to help suppress the switching power supply RFI noise. Suitable snap on beads are FSB31-1/2 for the 1-250 MHz range.
We have also had reported wireless HDTV boxes, and FOSCAM and AMCREST security camera systems causing RFI to garage door remote openers. Use our Garage Door Opener RFI kit to suppress the interference to the opener (VICTIM) – you need one kit for each opener. Maximize the distance from the camera to the openers may also help. Additionally shield cable to the garage door sensors may be needed depending on severity of the camera RFI.
Obvious Tech Note: make sure your remote batteries have enough energy to activate the GDO or the signal they transmit may not be large enough to over ride the RFI signal, but a fresh battery may be able to overcome the weak RFI source and allow the GDO to operate correctly.
