excuse me if the subject has already been treated several times, but I have low internet connectivity in my island. I therefore have two multiplus: one as a master and the other as a slave. I am in ESS mode and I recently bought 2 pylontec us3000 batteries. I can't get them to start. I suspect that the battery level is too low to let me start them... Indeed, when I turn them on: the SOC lights do not appear, only the RUN mode light works. As soon as I turn on the multiplus , I go directly to "alarm" mode with a red light and I have no more power, not even for the CGX
