Smaller batteries will work too.

2000mAh - https://www.adafruit.com/product/2011

2200mAh - https://www.adafruit.com/product/1781

4400mAh - https://www.adafruit.com/product/354

NOTE:  The 3D Solar Panel Stand is not included in the kit.  However, you can download the 3D Print files from the SwitchDoc Labs Solar Panel Night Light Kit product page to print your own.

We also sell a 3D Print of the Solar Panel holders for those without a 3D Printer.

The software monitors the solar voltage and turns the display off when the solar panels hit 2.0V.  Saves a bunch of power.

Example REST JSON Output

Open a browser (Safari or Chrome has been tested) and type:

http://192.168.1.154/

you will get (assuming you have the right IP Address)

{"variables": {"solarVoltage": 1.52, "batteryVoltage": 4.14, "solarCurrent": 0.00, "batteryCurrent": 2.40, "loadCurrent": 1.20, "loadVoltage": 4.97, "currentLEDMode": 0, "darkLight": 0, "Version": "005"}, "id": "", "name": "SDL_ESP32_BC24_SOLARNL", "hardware": "esp32", "connected": true}

All of the BC24 Solar Power Night Light commends return fully formatted JSON data which makes it easy to parse and get the values you want.

 

Data! Data! Data! More Cowbell!

SunAirPlus includes an I2C INA3221 3 Channel Current / Voltage Monitor and a I2C 4 channel 12 bit Analog to Digital Converter (ADS1015). The INA3221 allows you to monitor all of the major currents and voltages in the system (Battery / Solar Panels / Load - Computer ). You can tell what your solar power project is doing in real time. Here are some results from the SunAirPlus board using the onboard INA3221. You can see that the battery is almost fully charged and the solar cell voltage (actually a variable power supply on the test bench) is 5.19V and it is supplying 735mA. The Output voltage is 4.88V because we are fiddling with the board. The Library works like a champ.
