My smart solar 250/70 sits at exactly 49 degrees for the duration of charging. It is not fully loaded and the battery charge current sits at no higher than 50A during Bulking. Is the charger supposed to get this hot?
The heatsink is only warm to the touch but the front of unit is panful to the touch. I will upload some graphs below of current and voltage of the MPPT in question. I just want to make sure that the charger is not undersized in some way which is causing the extreme heat. I thought that I had oversized the charger more than required.
