Victron Solar Power Supply for Tiny House
- The aim of this project is to set up a small Solar 12V power supply (PVS) for a Tiny House experiment.
- The PVS will power an Arduino Uno to monitor the battery, the solar panel and the Load (current drawn from the battery) using a Victron MPPT Charge Controller.
- The MPPT Charge Controller provides this information to the Arduino Uno via serial communication (VE.Direct Serial port).
- In this experiment the MPPT Load outlet will be connected to the Arduino Uno using the power socket on your Arduino board.
- Use a 5.5mm diameter cylindrical plug with 2.1mm pin hole. A Positive voltage is on the inside pin hole and the Negative (or common/ground) voltage is connected to the outside cylindrical sleeve of the connector plug.
- For safety, a 5A DC fast acting fuse is connected to the positive terminal of the battery.
- The maximum charge rate of the 12V 8Ah battery is 2 Amps. The maximum draw currently will be less than 1 Amp for most applications.
- The Arduino Uno typically draws 40-50mA (12V - 0.6 Watts).
