MPPT Solar Street Light Controller– JWL ML Series

1. Introduction

MPPT Solar Street Light Controller – JWLML Series adopt high efficiency MPPT technology and combines with constant current LED driver all in one, the charge efficiency can be increased by up to 30%, is especial for solar LED street lights, with dusk to dawn and dimming function. Users can program the time and dimming value by infrared telecommunications to control LED lights’ working at night.

Model Choice: 

◆ JWL-ML-10A 12V24V auto,  40W/12V 80W/24V

◆ JWL-ML-15A 12V24V auto,  60W/12V 120W/24V

2. Features

Professional design to promote system reliability

1) Using international well-know brand semiconductor device such as IR.TI.ST.ON.NXP and so on.

2) Using industrial MCU total digital technology, without any adjustable resistance, strong anti-interference ability, no aging and drift.

3) High LED driving and charging efficiency, significantly reduce the product temperature.

4) IP68 protection degree without any buttons, further improve the waterproof reliability.

High MPPT efficiency

MPPT efficiency≥99.9%, System efficiency is up to 98%, improve the system efficiency & reduces system costs.

High Transfer efficiency

1) Charging efficiency up to 98%.
