DC Battery Breaker tripped

I am using a recommended DC battery breaker for my setup.


Setup is a 8.8 single phase inverter with two SunSynk 5.3 batteries.


The DC Battery Breaker is https://www.projoy-electric.com/File/2022-11-24-012239-f_$Zp1DA and is the 125A/160V version.


It happened both yesterday around 19:50 and today around 19:30.


This is a custom graph of just before it happened tonight.

These are the system mode settings for around the time.

Annoyingly also I was not alerted by any means that the breaker had tripped and only noticed because I was checking the app and the flow did not look correct and so went to investigate.

that error may just have been on the startup, as it’s from the grid side, your grid settings may be to low, see if you can check the battery output or input before it tripped and I can work out the amps before the trip
