I am looking for a "current-saving" solution for controlling a 12v actuator.
The actuator is to turn the solar panel, but it has to do it in cyclic-daily mode. The best solution I could think of would be 2 channels controlling relays.It would work like this: one channel pushes the actuator every couple of hours for a few seconds in the direction "behind the sun".After sunset the second channel starts a sequence of relays to return to the starting position "in the morning".The actuator has built-in limit switches.
The project has grown a bit and started to cost money,so price matters too.
I have considered simple watering programmers.They are fairly cheap and you can rewire the valve outputs to relays,but the problem is the minimum tripping time (1 min). I also looked at led controllers - they are too complex, often power-consuming. Controlling windows would be exhaustive as they can be programmed to tilt, but I haven't found anything cheap.
The priority is energy efficiency, 12v, minimum 2 channels, simplicity, price and time in seconds.I do not want to build this, I need a ready-made part as a spare part in case of "w".
