A datalogger for a solar inverter. Stores data in influxdb and displays it in grafana. Has load diverting capability, to use the inverter's excess power
Huawei SUN2000 compatible devices which working with Huawei Cloud Service command line bash API for monitoring or download data from their FusionSolarApp API
With these schematics and PCB's, it's possible to create a 230V AC 4KW inverter. The main processor is based on Arduino Nano, with help from a graphic processor Arduino Mega2560, to run the demanding graphic and interface to front buttons.
123Solar is a lightweight set of PHP/JS files that make a web logger to monitor your photovoltaic inverter(s). It just need a web server and PHP, no databases are even needed. The philosophy is: To keep it simple, fast, with a low foot print to run on cheap and low powered devices.
HA Custom Component to integrate data from ABB/Power-One/FIMER PV Inverters that support SunSpec Modbus (Sunspec M1, M101, M103, M160), natively or through the VSN300 wifi logger card.
My attempt to get meaningful values out of the UART protocol of the Solax Pocket WIFI and then bring them to a cheap microcontroller. The 30 bucks for a USB stick that has more quirks than advantages.
