ESS stop working in my system

Hello everyone,

here is my system:

2 MultiGrid 48-3000-70 (MASTER & SLAVE)

8x6 Battery Crown 350ah

PV inverter at AC out 2200w solar pannel /PHotowat(DANFOSS) ULX1800i

. So I use ESS ,it ran perfectly for about a month, which means I could charge and discharge the battery with energy from/to grid ,setting grid point to use the battery at night with A/C

. Until one day,nothing is working,and my Multiplus stills in Absorption and Float

Sometime the ESS reacts to the setpoint ....My SOC stills at 97% to 100% and most time, these LEDs Mains On, Absorption and Inverter are on at the same time and now the Inverter led stop lightening...

I've done:

-all firmware to the latest

-resseting


thanks for your help

Hi @ramassamy

I've found the cause:


You are using German grid code, with the option 'use aux1 to disable feed-in' selected.

Also you have a sensor connected to aux1


This sensor causes feed-in to be disabled.


Simply uncheck the 'disable feed-in' option to fix this.


I'll add this to the faq.

Hi @ramassamy, Did you try to reset the multi? also make sure the switches are on the 'I' position and not "II'

Hi @ramassamy

1)what switches are you telling??dip switch ?? --> not the on/off/on switch at the bottom of the unit (right side)

2)i have not resetting the multi now...i have first do it ,but nothing happened (firm 462) and i am with firmware 465 (is RESET= ON/OFF Switch on and switch Off the multi ,if not i have not resseting ) --> yes, reset in CCGX is basically the same as switching the units off and on again, no settings will be erased.

what happen if i resset the multi by thye CGX ,do i need to re-install settings and assistant ?
