Solar charging voltage and battery acid
Went to check on my newly installed 120watt panel with a Xantrex c35 controller. I set the bulk voltage to 14.8 with temperature compensation. When I checked the voltage at the battery mid day (around...

I am just now looking at SOLAR PANELS for my OFF-ROAD POPUP trailer and it seems the SOLAR CONTROLLER specs mimics my smart mode converter/charger very nicely.
To me the solar controller should produce the same charging voltages my on-board smart mode converter/charger does. My PD9260C highest DC voltage is 14.4VDC when doing smart mode charging. Even when the PD9260C goes into EQUALIZATION MODE it only produces 14.4VDC for 15 minutes every 21 hours. I have seen other converter/chargers went to around 15VDC doing this equalization mode but was for only a short 15 minutes time.
It appears to me the SOLAR CONTROLLER is just another SMART MODE Electonic Charger device except its input is being fed by the SOLAR PANEL OUTPUTs and regulated down to the optimum required battery charging DC requirements.
I used to boil out my battery fluids with my single mode converter/charger running a continuous 13.6VDC for a long period of time but after installing the PD9260C this has completely gone away. I still check my fluids or a regular basis but always find them where they are suppose to be.
