Hello,
I am using an off the shelf solution which is a 12V DC programmable digital timer switch part number BRX1224PTS1 from BRAZIX.
The timer is fully programmable but it is not waterproof. I have placed it inside a plastic box right by the batteries where also my charge controllers and inverters are located.
They also have a 24V DC programmable digital timer switch part number BRX24PTS1 (since I am not sure which one you need).
You can Google both part numbers including the brand and you will find their website.
I have the 12V DC Timer running a small 12V DC irrigation system using a windshield washer 12V DC pump. I have it set to turn ON 4 times/day 7 days/week. I also have a second timer running six 12V DC CFL lights at night on the property.
Cheers
