I have a raised garden vegetable bed fitted with an electrical slug & snail deterrent. This deterrent consists of two bare conductors spaced about 1cm apart that run around the bed's perimeter (around the outside, a few cm's down from the top edge). Currently, I power it with a 9V battery connected to the wires via a resistor that limits current flow to 180mA when the conductors are shorted. This does a great job of keeping the bed slug & snail free.
I'm looking into replacing the battery with a solar panel powered setup. Clearly, as most slugs & snails visit at night, I would require battery backup and this is the bit I don't understand. Could I simply connect a sealed lead acid battery, of suitable voltage, directly to a solar panel (maybe a solar panel designed to trickle-charge batteries?) then also connect battery, via resistor, to the two 'electric fence' conductors? Or do I need some sort of controller?
Advice much appreciated, thanks.
