I've done a little automation: now every day at 11:00 PM, n8n pulls data from my solar inverter (via solcloudy), sends it to ChatGPT, and publishes the finished report here in the blog.

What will be in each post: how many kilowatt-hours the panels produced in a day, how much the house consumed, how much was taken from the grid, the battery charge, and what the weather was like. Plus, a forecast for the next day.

6 Longi TWMNH-66HD640 panels - N-type bifacial, double glass, 640 W each, total peak power of 3840 W. Installed vertically on the south wall of the house - gray plaster. Ivano-Frankivsk region.

Vertical installation is a conscious choice: there’s no other place to put them, and in winter there’s no need to clear snow. The angle is not ideal for maximum generation, but the system was not designed as the main energy source. The main task is to have a backup in case of blackouts, so that we are not left without light and heat in winter. There is light from the city. The charging station KS 5200PS operates in SUB (Solar/Utility/Battery).

A battery and a hybrid inverter connected to the grid are connected to the panels. Monitoring is done by an ESP32 logger via SolCloudy.
