10 A PWM solar charge controller
The Morningstar Sunlight SL-10L-24V is a pulse-width modulation charge controller rated at 10 A for 24 V battery banks. It regulates power from a solar array to maintain reliable off-grid charging. The unit is designed in the USA by Morningstar Corporation, established in 1993, and is built for harsh environments including seaside conditions.
Integrated lighting control and test button
The controller includes a microcontroller with ten customisable lighting programmes and an on-board timer accurate to within two seconds. A rotary digital switch sets lights to stay on for two to ten hours or all night, with an ON/OFF/ON option that activates lights before sunrise. A test button verifies installation by switching lights on during daylight, while an LED indicates the selected lighting mode.
Three-stage charging with temperature compensation
Series PWM charging runs through bulk, absorption and float stages to extend battery life. Temperature compensation operates at the controller or via an optional remote sensor. The 10 A current limit defines the maximum array input the unit can handle; larger off-grid arrays requiring higher current will exceed this controller's capacity.

Questions about this item
Will the optional remote temperature sensor need replacing over time?
The controller supports an optional remote temperature sensor for battery compensation; the sensor itself is a separate accessory that may wear out and need replacement after extended exposure to the elements.
What limits continuous operation at the 10 A rating?
The unit is a 10 A PWM controller designed for 24 V systems; sustained loads at the full 10 A will eventually hit the controller's current limit, which is the first constraint under continuous use.
How much heat does it produce when running all day?
The PWM design runs with low self-consumption and no fan, so heat output is minimal; the rugged, corrosion-resistant enclosure is built to dissipate that heat passively even in harsh seaside environments.
