I installed two IP22 Blue Smart Chargers.
The case is VERY hot even when running at 50% charge current (15 amps setting with 30 amp charger) and HOTTER when running at full output (30 amps). At full output (30 amps), I don't hear a fan or feel any airflow. The case is alarmingly hot. Too hot to touch.
Are both units defective? Do I need to add an external fan and epoxy some heatsinks to the case?
