I have question regarding start of EVCS if I can export to the grid only 200W max. Is there any chance to start auto mode ? There is always message : Waiting for the sun, because solar system is producing only for the house + 200W for export, but I think EVCS need production much hugher (+1300W ?) …

Hi Alex. So, auto-mode can work without the ‘feed-in’ feature, and it can wake up the MPPTs for EV charging. I propose the following: Configure your system without considering EVCS. ‘feed-in’ disable, ESS, etc. Reset all EVCS settings to default, as I can understand you modified some internal s…

I tried to increase a house consumption, but without any change : [image] but there is enough solar power

Right now it looks like a problem is solved. Internal change was necessary. The main value that was changed: ‘Battery powered’. Grid power for ‘feed in’ detection. register 5091 to -10000 to not detect ‘feed-in’ on my system. Thank you @Nicolas for your help

Hi! maybe I have the same problem. " I have a new EVCS, works ok manual and programed, But in auto mode, says" Waiting for sun" when battery is 100% and system is sending solar surplus to grid (2.5k) This is a standar solution? I need to make this change in my EVCS? How can I change this register…

I think it’s different problem. When my grid feed-in was 1500W, auto mode was working without problems. But if you want to test register change, you can use sw named QModMaster.
