Hello,
In one installation I have a multiples II working as ESS.
Charging is disabled, but last night it charged from the grid. How to turn it off?
I was under the impression it cannot charge from grid if charger is disabled.
The PV system is all DC. Battery level was at the set lowest 15%.
There are also some controls in the ESS settings, maybe these are turned on ????
Check your 'sustain' voltage in the ESS assistant
@Paul. The options are off.
@ Boekel. Sustain voltage is set to 48.00V as it is a Pylontech battery. The current voltage is 48.70 at 26%. It was for sure over 48.00V.
The active SOC was changed to from 15% to 20 and then 25%, which is expected. So over night it has charged to 26%
I suspect that is has to do with minimum SOC. I want the system to wait a few days to have a better weather for PV.
This change in the SOC that would be why.
(The active SOC was changed to from 15% to 20 and then 25%, which is expected. So over night it has charged to 26% )
As it would have tried to fill the batteries back to this level
My settings are as below, and I find that as soon as the active level is reached, then any more power needed is drawn from the grid so that the SOC is not lowered
I am not seeing my ACTIVE SOC change though by its self that is.
Currently I am quite happy with how this is working FOR MYSELF that is
My system is a multiplus 48/5000 FW 433
GX Venus FW 2.23
Litto 5Kw Grid Tie inverter with 4.5 Kw on 2 strings
48 volt 20Kw LP batteries with a 123smart BMS
Last night it has charged to the new active SOC limit of 30%.
Is there a possibility to really deactivate the charger. The software deactivation is a fake switch.
