“Solar monitoring system measures voltage, current and power from panel, and from two outputs and voltage on battery.
This board measure input voltage, current and power from two sources. Board have two outputs. Each have voltage, current and power measuring. Voltage, current and power measure with INA219 board from Adafruit. Input from solar panel is completely isolated from ESP8266 and 5V. Every inputs and outputs have 3A fuse. I measure temperature and humudity inside box with AM2301 and measure heating temperature with termocoupler and MAX6675. I2C bus is connected via level shift converter to ESP board.”
