Merry Xmas
Ross!
The
solar panel might put out say 21V but as soon as it is connected to a battery, the battery accepts all the current from the panel and the voltage measured at the battery drops. If you hit a 12V battery with the 21V from the
solar panel the battery will accept the current and will boil.
My caravan has a 12/24V
solar regulator. I disconnected the battery to do something, then hooked up again and saw 17V on the gauges, which told me something was wrong. I disconnected the battery then read the manual and the fine print tells you that the battery must be connected to the regulator before the panels, otherwise this will happen.
What model regulator is yours?
