I am planning an irrigation system controlled with DC powered OpenSprinkler using 24vac solenoids (bermad s-390-3-d, 24vac, 130mA, 2.2Watt) and powered by 12v battery (maybe later will be backed with a solar panel, but it’s not relevant now).
I have two questions regarding this:
1. What do you think, would be better to use 12v (directly from the battery) or 5v (converted with a cigar plug adapter) to power OpenSprinkler.
I mean better in context with the solenoids life cycle first of all.
2. Are you planning a rpi version powered with DC? 🙂
