This is a online information server with rest api based on esp8266 and Victron Solar MPPT Solar Charge Controller
The following hardware is required:
- D1 mini (ESP8266)
- Level Shifter 3.3V / 5V
- Victron MPPT Charge Controller (like SmartSolar 100/30)
D1 mini -> Level Shifter 3.3V / 5V
D7 / RX -> LV1 / TXI
GND -> GND
3V3 -> LV
Level Shifter 3.3V / 5V -> JST Port am Victron SmartSolar
HV1 / TX0 -> 2 (TX / White)
GND -> 4 (GND / BLack)
This sketch is for following development environment
Arduino
Following libraries are required

Setup wifi in esp8266-victron-mppt-solarchargecontroller.ino:
const char* wifi_ssid = "xxx";
const char* wifi_password = "xxx";
Setup victron device in config.h:
#define MPPT_100_30 // Define used Victron Device
Actual Supported:
- "MPPT 75 | 10"
- "MPPT 75 | 15" tested with FW 1.56
- "MPPT 100 | 20" tested with FW 1.5 / 1.56
- "MPPT 100 | 30" tested with FW 1.59
Following files needs to be uploaded to the ESP8266 (D1 mini)
