Mike, I’m very impressed with your solar set-up! ?On our Alaska farm, being totally off-grid, we installed solar back in about 2004. Ours is a 48 volt system with 16 130 watt solar panels connected in series and parallel to give 2080 watts at 48 volts and we have 24 6 volt lead acid batteries also in series and parallel. ?We have a 48 volt charge controller/inverter that provides power to the house. ?Our radio set up runs off house power and what we found was the inverter caused significant RF interference on HF radio, probably in part due to the system being 20 years old. ?I tried the usual methods to control the interference but without wanting to spend too much time or money on it we instead would turn off the inverter and run the radios off a 12 volt battery instead. The result was almost zero noise.
We plan to install solar at our house in Stewart as time permits and your set-up seems to be a good example to follow. Without needing to provide 120 volt power to a whole house, the need for a large inverter is eliminated. ?We did determine the solar panels themselves provide no detectable noise.
I will be interested to follow updates on the performance of your system!
