Any idea why my batteries are bubbling at night? Been happening for 1 week, usually from 10 p_m to 1 am . Batteries bubble for 2 to 5 seconds, every 5 to 10 minutes. Ot is a quick release of bubbles, like blowing air through a straw into a glad of water. In the morning there is some battery fluid on top of a one of the two batteries, maybe 1 teaspoon worth. All readings are normal and system seems to be functioning well otherwise. Batteries are about 6 years old. Any ideas? Is this dangerous? Thank you.

Do you have several batteries or strings of batteries in parallel? If so one string may have a shorted cell and is being charged at a high (for it) voltage by the other batteries.SunnyBoy 3000 US, 18 BP Solar 175B panels. -
