Phoenix 12/1200 overload at around 700VA

Since a few days I am encountering unexpected overload alarms consistently around 700VA. It is Independent of what device is causing the load.
Please see the screencapture video of the Victron Connect App

I note that I have used in the past the same consumers without any problems.
Wonder where I should start troubleshooting?
Many thanks in advance.

Hi, hot temperature reduces the power capacity of the inverters, you could look if there is any obstruction for the air flow, dust, etc...

Eventually, is there a difference in the temperature room regarding what it was before the issue started ?

Thanks michelg. I can exclude temp and airflow influence as the unit was not moved and used to work in much hotter days. I wonder if the cables could be the reason. However would the unit not throw a low bat or low current error instead of overload? Thicknes of cables are at specs however may be the connections need to be checked.

Hi Bladerunner, a few questions : any breaker in between the inverter and the battery ? Last week one of the breakers went dead in my setup, so it could be a similar problem, or any loose connection. Also, check the battery state (how hold is it ?), the cabling is it big enough for the required amps ? And of course checking the connectors in the inverter and battery.

Sometimes things go well during a period, and suddenly start creating issues. The weakest element of the installation is usually the key to solve the issue.
