The system only fails at night with sufficient battery power and at low loadings, i.e. circa 450W. I updated the system a year ago and now it will at least restart. This helped me to identify two breakers that will trip the system when I switch ony one of them on following a system trip. Now this is where it becomes strange: On the one there is two fridges (which could make sense), but on the other one several plugs in my living room with nothing on, accept in standby mode. Hence my requirment to identify if there is a spike of more than 6kW, and if there is no spike then my problem is the Goodwe (which I am starting to suspect more and more)

Hi, my Goodwe 5048ES sporadically trips on backup at night whilst the reports dont show an overload. This could be because of a too slow sampling rate for the reports? Have anyone expierenced this and is there a way to get more detail from the system? My system consist of Goodwe 5048ES (4.6), 16 PV panels (6.3kW) and 6 Pylontech 2.4kw batteries.

Hi Paull99, I upgraded my system by adding two Pylontech US2000C batteries to my existing 4X US2000B batteries (Goodwe ES 4.6kW inverter). They are connected as follow: A1 2000C (Master) B1 2000B A2 2000C B2 2000B A3 2000B B3 2000B All batteries connected in parallel and group A and B connected in parallel on a busbar at the DC Breaker. Before adding the two C’s, the BMS and CT Meter worked fine. However, after the upgrade the PV Master reports a CT and BMS communication failure. As per the Goodwe Flyer, I disconnected Pin 2 and then only connected pins 4&5, but this problem persist. Any ideas? Thank you
