I've built a couple of cheap and simple DIY solar systems. One running pumps and fans in a greenhouse, another running an automatic door in a hen house.
I'm going to build a 24' dome greenhouse this year and want solar power again.
This time I want the system to charge the batteries first.
The batteries will only run pumps, solenoid valves and linear actuators for windows (a few minutes a day).
Once the batteries are charged I want to then use the solar power to run fans.
If there is no power to run the fans then that doesn't matter as the fans won't be needed.
This may be a normal requirement, but the cheap controllers I've used to date don't appear to do this.
So... can someone point me at controllers that can be configured to make excess power available on one circuit and battery power on another?
