Charge Controller with Nightlight Function

One programmable nightlight function PWM regulation (series type) Integrated temperature compensation Three-state charging method SOC and voltage controlled LVD Solid-state circuit and load protection Reverse polarity protection Fully electronically protected

The SMLNL series is a sophisticated solar charge controller family for low cost applications.

The electronic circuit is equipped with a microcontroller that provides high-efficiency charging technology together with a number of outstanding status display, warning and safety functions. The SMLNL series comes with two nightlight function mode. One of them is programmable that switch on the load output for a adjustable number of hours from dusk.

The nightlight function is overridden by a battery deep discharge protection to avoid excessive discharge and damage of the battery.

The temperature-compensated three-state PWM charging method (boost-equalize-float) is now adjustable to sealed and vented lead-acid batteries.

The low voltage disconnect function can be controlled either by SOC or by voltage.

The battery status, charging status and load status are clearly indicated by 5 LEDs.
