October 10, 2025Oct 10 I have Easun SMW 11KW inverter with firmware U1 78.10 / U2 38.18.In the morning, when it dawns, the inverter starts the loop and counts down on the screen. The video is attached.I'm using inverter for off grid purposes. There is no problem with charging the battery through the panel and providing AC power.Does anyone know why inverter is doing that? and how to fix it? video.mp4

The video is attached.I assume that it has been running all night before dawn?That sounds like it might be a power supply issue to me. Check and/or replace the usual suspects, per this post.But it could also be something to do with the high PV voltage solar charge controllers. I don't know much about those, sorry. See the repair topic for possible clues. Edited November 7, 2025Nov 7 by Coulomb Wrong link
