Arduino software and hardware to control a 12V off-grid solar system with 1000W power inverter for a fridge and lighting. The arduino is a 3V JeeNode, but I might change it for a simple arduino.
Circuit Diagram The circuit diagram and schematic for Arduino Power Supply Shield is pretty simple and doesn’t contain much component placement. We will be using 12V DC Barrel Jack for main voltage ...
This Automatic Battery charger circuit can be used to charge a 12V, 7Ah battery, or above. The charger maintains float voltage, if battery is fully charged.
