Hello,
is there a way to check if cooling fan or internal temperature sensors of my smart Phoenix are working properly?
Problem: My smart Phoenix is dropping an “over temperature error“ when constantly beeing used, supplying a load far below the treshold.
Ambient temperature is about 20 deg. celsius.
Are the fans running?
Does it have a good clear space around it?
Is it in an enclosed area?
You can remove the top cover for more cooling, if you are certain nothing will fall into the unit.
It looks like there are two sensors within the toroidal transformer, is there any way to measure if they are sensing properly, and/or to calibrate them?
Airflow through heatsink looks not to need any optimisation.
I assume, it is getting warm, because the loads are high. I had the same problem, even with an external blower. Change to the 5000 inverter solved MY problem.
