Hello everyone,
I’m excited to join this community and look forward to learning, sharing ideas, and collaborating. I’ve set up a system powered by a solar panel with two batteries connected in parallel to provide a 12V output. I’m using the BlueSolar MPPT 75/10 charge controller to regulate the input from the solar panel to the batteries and to power a device that needs to remain on 24/7. The device is Arduino-based. However, the voltage is reaching up to 14.8V, which triggers a protection mechanism that shuts down the Arduino, causing data loss until the voltage drops again. I’m trying to find a way to prevent the voltage from rising that high. I found a device that I thought could help (COM-18732 SparkFun Electronics | Power Supplies - External/Internal (Off-Board) | DigiKey), but when I connect it (input from the solar controller and output to the Arduino), it shuts down the system. Any suggestions on how to stabilize the voltage or properly integrate this device would be greatly appreciated.
