Product Introduction

DM series MPPT solar charge controller is designed for solar street light system, which has step-up LED driver inside, and can realize 3 levels dimming and morning lighting function via wireless control. It supports both lead acid and lithium battery and the protection level is IP68 which makes it totally waterproof. The energy utilization of our DM will be 15%-20% higher than traditional PWM controllers.

                                                                                                   

The DM Series Controller Has Two Different Current For Your Choice:

DM120 (12V/24V 10A)   DM160 (12V/24V 15A)

Product Feature

•Features true MPPT functions, applicable to monocrystalline, polycrystalline and amorphous silicon solar panels serially connected in various numbers, significantly improving the solar panels' energy utilization ratio.
• Adopts the MPPT solar charging technology, with a max. solar panel open-circuit voltage Voc ≤ 60V and a max. solar panel power Pm ≤260W.
• Features load boost constant-current output, able to directly power a maximum of 18 light bulbs in series, with a max. load power Pled ≤120 W.
• Adopts an improved charging algorithm that supports 12 V and 24 V lead-acid batteries and lithium batteries, and the user can set the operating modes for lead-acid batteries or lithium batteries accordingly.
• Boasts a load triple-stage brightness adjustment and morning on design, with an operating duration adjustable from 0 to 15 hours and a power settable from 0 to 100%.
• Features a system status log function, able to record a maximum of 7 days of system status, comprehensively and effectively monitoring the system's conditions.
• Data communication adopts a multi-time two-way handshake protocol and a data compression algorithm, realizing precise and fast data transmission.
• Features an intelligent power mode which can extend the battery life to its top limit by adjusting the load power automatically according to the remaining battery capacity.
• True constant current rather than current-limiting control ensures smooth and stable output current, effectively reducing LED light attenuation and extending LED service life.
• With an infrared remote control function, operations including setting parameters, reading status and viewing historical data can be conducted.
• A metal case and an IP68 waterproof level enable the device to operate in various kinds of tough conditions.
• An overheat protection function enables the device to scale down the load or shut off the load completely when its temperature exceeds a certain point.
• A range of protection measures such as battery reverse-connection protection, LED short-circuit and open-circuit protection, etc., put the system under comprehensive and constant guard.
The following are functions of "-U" series
• Boasts a wireless Internet communication function, able to conduct remote monitoring and real-time management on street lights via the solar power street light management system.
• Supports remote light on/off switching and dimming, as well as modification of battery and load parameters.
• Monitors solar panel voltage, current and power, battery charging and discharging current and voltage, load operating status, controller operating status and other data, and automatically triggers alarms when failures are detected.
