1) The SMLNL series is a sophisticated solar charge controller 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.
2) 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.
3) 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.
