450/100 solar charger thowing circuit breaker to pylontech batteries

My charger seems to be tripping the circuit breaker to my pylontech batteries (3 x US5000).It has worked perfectly for 15 months.When I reset the breaker,it immediately throws and I get a high battery voltage error.Now that the panels are not irradiated the breaker stays on ?

I'm thinking either a faulty breaker or the solar charger is kaput.

The batteries are showing no errors and are discharging as per usual

No alarms have been triggered

I have used an artificially high voltage on the relay settings to activate my airconditioner for the cabinet in conjunction with a thermostat,but the relay is currently switched off even though the charger still recognises the value set and triggers a software alarm on the display of the charger,but this has been like this for months with no problems.I have adjusted this setting back to normal for now,but it was set when the high voltage alarms were emailed to me earlier today.I think the email alarms were triggered by me resetting the circuit breaker,but it could have been isolating the array.

Better to use a fuse instead of a breaker. Especially the cheaper ones.
