IIRC, the solenoid type draw .5 - 1 amp when activated. That is one
reason why they and similar products don't always fit well with solar
setups, since you don't want to waste that much of the solar panel
output. Of course you can still use them with solar but best to
understand the draw and avoid it when the solar is providing the only
charging current.
