Useing for signal Nightlight and Double NightlightOne programmable nightlight function;MPPT 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 SMTNL series is a sophisticated solar charge controller family for low cost applications. The electronic circuit is equipped  with a microcontroller  that provides high-efficiency chargingtechnology together with a number of outstanding status display, warning and safety functions.The SMTNL series comes with two nightlight function mode. One of them is DIP switch 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 MPPT charging method (boost-equalize-float) is now ajustable 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.The SMTNL Controller has a group DIP Switch for the Nightlight Controll.At the approach of the evening, after a short time delay, Negative Pole Automatic Power ON. User can define the time of load "ON" ,Normally timing measure time by the hour, Maximum is 8 Hours.
