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...
Hi there, I have exact same unit that gets extremely hot at 30A, 15A is fine. When I took it apart I noticed that there is another fan meant to be in the back of the unit. But they moved it inside the unit, makes sense I guess, but it still gets extremely hot, I berely can hear a fan spinning. Since I like the charger, I will purchase another fan like this and install in the back of the unit to allow extra air flow. Will wire parallel to the installed fan. Will see how it works...

About to add a fan also. Having a blonde moment. which direction should I direct the fan? pulling hot air out or blowing in?
Installed my new IP22 today, put 1/2 inch spacers (nuts) between wall and case to help airflow.
Case feels hot, but is "only" 51°C, so I'll watch it.
