SMTNL10/15/20/30/40

Function

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.
