I want to build el. circuit : arduino, relay, el solenoid valve 12 V ( app. 5 W) for watering garden at my village house.
There is not installed electricity.
Also is needed accumulator to power stated circuit. Please help me by suggesting what is the optimal accumulator capacity ( Ah)?
I would load accumulator once per 2 months.
Or is there any better option ? Goal is the lowest investment.
Solenoid valve (https://www.dx.com/p/electric-solen...mally-closed-golden-white-246864#.VrZ2M08hMp4) has to run app. 1,5 h per week.
