Installed solar panel to drive siren. 2 weeks in and notice battery drain. Seems panel is not topping up battery. I have cams with solar and battery…no problems. So swapped battery but still no charging
How can I check that battery is receiving juice ? App for cams shows percentage but siren doesn’t. The fitting from solar panel to siren is not tight as panel connector seems small…or the hole in siren is to big maybe.
How can I test this other than waiting for a battery drain in a few weeks ?
