Solar panel and battery noise
Hello all! I am running 2 6VDC deep cycle batteries in series on my travel trailer. I recently bought a 120W solar panel that is for a 12V circuit. I hooked up the solar panel using the charge...

Thank you for your replies. I did forget me mention that the batteries are the flooded type. I had a look at the water level and the plates are all covered. Could maybe use a little top off but currently the plates are not exposed.
The charge controller is not a very good one (came with the solar panel). I decided to order a Renology Voyager 10A PWM controller just to be on the safe side and it looks to be a much better unit (bonus that its waterproof). When I get it I will try the setup again and see if the batteries still make the noises.
Before hooking up the solar panel I had the RV on shore power so the batteries were fully charged. The only thing that was depleting them were the lights that I turned on but those are LED so minimal draw. It does almost seem like the batteries were being overcharged as the charge controller kicked into charging very quickly when I turned the lights on or there was what seemed like a very quick voltage drop. Does that seem normal?
