Abstract

This work describes a low cost solution based on ESP32 processor and the LoRa controller SX1276 for interoperability of photovoltaic inverters with WiFi interfaces. The system firmware is developed in C++ and MicroPython. Also, this work describes a solution on Python for Raspberry. For the test of firmware solution, we use a HELTEC platform. This work present also, a development of Hardware solution on PCB with more functionalities for different kind of interfaces in PV inverters.
