Introduction for SMLNL Series Solar Charge Controller
The SMLseries is a sophisticated solar charge controller family or 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 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 battey.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 cleary indicated by 5 LEDs.
SMLNL Series Solar Charge Controller Has Following Functions:
1.Battery State-of-Charge display with 3 LEDs
2.Acoustic load disconnect pre-warning
3.PWM-regulation (series type)
4.Boost, Equalize and Float charging, also for VRLA
5.Integrated temperature compensation
6.Large terminals (up to 24mm2 wire size)
7.SOC and voltage controlled LVD
8.Fully electronically protected
