Wiring Multiple MTU's with Noise Filter
« on: November 23, 2011, 08:27:33 AM »
I have a solar installation that has two MTU's. I have determined I need to install a filter at the breaker panel to improve PLC communication.

Question: Do I need two filters or can a single filter be wired to both MTU's?

You must use a single filter. The filter isolates the TED equipment from the noise source in your system. The filter should be installed so both MTUs and the gateway are on one side of the filter, and the rest of your electrical equipment is on the other side.
