when I will increase a feed-in limit from 200W to 1500w, export will increase:
this isn’t my problem, I have enough power.
problem is this situation :
now when I will connect a car, charging will not start.
I will get information : “Waiting for sun”
is the setting in ESS
Self-consumption from battery set to all system loads?
I’m sure it’s EVCS setup problem, not ESS setup
all is single phase
sorry, no.
I do not understand what to do and why, but all measurements are right now measured correctly
I have only 1phase system
on the next 2 phases there isn’t any solar production
EV will not start charging. EVCS will tell : “Waiting for sun”
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 settings related to auto mode. You can use ‘Keep wifi and access settings’ to simplify things.
- Disable ‘Allow battery/grid power for auto mode’ or reduce ‘Battery/grid power timeout’ to avoid charging EV from the battery\grid.
- Do not use ’ Allow low excess solar power for auto mode’. Seems you don’t need it.
I think that auto-mode will work with such a configuration.
If you see any problems - ping me here, I will check the behavior(but before modifications of any internal settings).

-OK,configuration done
Actual situation without car:
-EVCS is in the default
-EVCS configuration is now:
I will send situation when car is connected

car connected:
and Waiting for sun. This information is there immediately when start button is pressed
ok. I’ll send you a PM.
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 5091??
Thanks!
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.
Hi @Viosmo. Which FW version do you have?
Does your system have more surplus power than 2.5k?
Seems your EV charging by 3phase and need at least (6A*230v)x3 = 4140w.
When the battery is full, does the SoC show as 100%?
