Greetings, I have a multiplus 48/3000 which has been working fine for years. I have now installed a 2.5kW load, which I need to run for an hour or so. After half an hour I get temperature warnings, the multiplus goes offline for a few minutes, restarts, operates for 5 minutes, another warning etc.
There are no other loads on the system, and vrm portal is showing a consistent load of 2500W.
The multiplus is installed with lots of free space around it, and the ambient temperature is about 22C. The fan is working hard.
Any ideas how to correct this?
