Description
The SunDale 20A PWM controller supports 12V/24V battery charging with an LCD and status LEDs. Select the appropriate battery profile for LiFePO4, LTO, gel, AGM, wet lead-acid or calcium batteries. The IP65 version supports surface or flush-panel mounting; follow the manual for terminal protection and installation. An external battery temperature sensor is optional. PV limits are 25V at 12V and 50V at 24V. Equalization applies only to the specified wet lead-acid and calcium profiles.
