Is there any way to get an Arduino to recognize when the battery is fully charged and flip a relay? I'm thinking if I set my charge controller to 57.4v (4.1v) and have the Arduino check for 56v (4.0v), I could have it flip a relay to turn on a secondary load, such as a water heater, once the cells are fully charged (4.0v) to capture wasted solar power.
I'm aware there is a device that does this for grid-tie power that was mentioned in the group before. I'm looking to do it DIY with my battery setup. I don't like when my batteries charge completely by noon and all that power is wasted...
Thanks.
