Blue Smart IP22 12/30(3) very hot case

Hi,

I have installed the above charger in my camper van on a 170Ah LiFePo4 battery, with around 20°C environment temperature.

If I charge with 30A the case is going up to 70°C !

I checked all cables and contacts, the the cable length 1,5m and everything looks fine.

Is that normal ?!?

Why didn't the internal fan starts earlier with a little more speed to cool down ?

Charger operation is totally silent whilst the cooling fan is off; the cooling fan is only activated during demanding periods, when it is necessary.

My suggestion - to help natural convection work better maybe help the unit by mounting it vertically.

but the units internal sensors will turn the fan on when it needs to

In my case the installing environment is a little bit difficult and I can't install it vertical... horizonal is the only option here.

I think 50°C would be okay, but 70°C are to hot.

In the manual are no limitations about the alignment, so if there is no other solution, I must search for another charger...
