EasySolar 48/5000 Internal fan

Hi,

I’ve a 8 years old EasySolar 48/5000 that run non-stop from March 2020. It work perfectly since and I’ve never be worried about his functionning.
But, since one Week, the outside temperature where I live goes above 40°C. The room where the EasySolar is goes hot too, even if the temperature controlled fan I had installed in the room to blow outside the hot air work. The room is more or less the outside temperature at the end of the day, 40/45…

I monitor everything, especially the batterie temperature to be sure to not exceed 40°C and reduce the available power.

Today I go in the room to check everything is OK and I noticed the EasySolar fan doesn’t running. The case is little hot, maybe 40/45°C max as I can keep my hand on it easilly.
The Multi load is between 800 and 1300W. I’ve no temperature alarm, no cutout, no power shortage. Everything seems to be OK.

So, I would know what is the temperature / temp + load / load only point where the fan normaly goes ON to test if the fan goes ON and in case of faulty, replace them.

Is it possible the MultiPlus that control the fan is faulty itself ? How to monitor the fan or internal temperature of the multi ?

Thank you :slight_smile:
