Yes they happen, Robb Cary of Battery Testing Co. has some frightening photos.
I have lost contact with him however. I have had an experiance, but I did not
take pictures. When you find the top of the battery and or battery enclousure
blowen to smitherens it was a hydrogen explosion. Sorry

H2S is slightly heavier than air, but I vent with the inlets on line with the
tops of the battery, and the outlet at the highest point.
If there is a lot of space around the bottom of the batteries, I might lower

I have sold thousands of off-grid PV systems and hundreds of on-grid PV systems
