Propane sensor going off

[JRRNeiklot]

I just got my solar hooked up and the propane leak detector keeps going off constantly. I talked to a guy at a local RV shop and he says the propane sensor will sometimes detect other gasses and go off, so I'm worried about hydrogen gas. He also mentioned that the sensor could go off if the voltage is incorrect. I'm showing above 13 volts on my battery monitor. So, unless the charge controller is roasting the batteries, there shouldn't be enough gas venting to cause any problems, correct? I haven't yet gotten the battery bank sealed. I figured I could leave the doors to the passthrough storage open (that's where the batteries are mounted) and pull the slide trays out that I have the batteries installed into until I get them sealed and vented. I disconnected the batteries and plugged into shore power and the sensor does not go off.

I'll attach a photo of the battery bank.


Anyone have any ideas on what's going on here?

Thanks.

How old is the RV/detector? Many detectors will go off (or at least beep sporadically) if they believe they are at the end of their life and need replacement.

I would very much doubt its gas from the batteries setting it off. If you're getting sufficient gas from the batteries into the living space of the RV to set off any alarm, that in itself is a problem to fix by sealing the battery bay from the living space better. Acid fumes in living spaces are not really a good thing.

You could pretty well verify that the solar is unrelated by disconnecting the solar panels from the controller (or seeing if you continue to have problems at night).
