Build a 1kW 80V 35A WiFi MPPT Solar Charge Controller, equipped with phone app datalogging telemetry! The design has been intensively tested for months with a 8S 24V LiFePO4, 640W off-grid setup. The project is completely open source. Arduino ESP32 based and uses a truly Synchronous Buck MPPT design. It works with all battery chemistries up to 50V (6V/12V/36V/48V) and solar panel setups with a Voc up to 80V (Imp: 30A). You can modify this for 150V solar setups, more on that on the written tutorial! Your one-stop PCB prototype Partner PCBWay: ( UPDATED FULL WRITTEN TUTORIAL: - - More updates and details found from my written instructable tutorial! - The MPPT can now support batteries up to 80V (12V/24V/36V/48V/60V/72V/80V), through a mod. Kindly visit 'step #38' of the Instructables tutorial link. Synchronous buck based MPPTs are one of the most energy efficient designs. Premium commercial gra
