Green Energy LED Display

A customized solution base on Nigeria power situation , battery and generator hybrid way offers a sustainable and cost effective solution to power the outdoor energy saving LED Screen.

With the most advance and energy saving LED Screen , average power consumption could reduce to 80W/sqm . By keep improving the color contrast of outdoor LED Screen while keep lower down the brightness level is what we aim for from R&D design , through this way to lower down the power consumption while get a vivid colors & visibility under the strong sun in the day time .

Product Description

We offer hybrid power solutions to drive the LED Display , solution gathering the power source from grid , generator , solar panel . In West Africa like Nigeria , city grid power is not efficient , we designed a solution to power LED Screen by use generator and lithium battery together . As LED Screen brightness is adjusted as per day and night , the level is different . If 100% drive by generator , it cost lots of energy waste during the low brightness time like night time .By use battery drive LED Screen during the day and night , during the LED Screen off break time use generator to drive battery , full utilize each source energy efficient .Energy saving start from energy efficient is the best way .

Lithium Battery and Generator Powered LED Display

In west Africa like Nigeria , solar panel is an issue to be installed in the crowded city center , 100% drive by generator is costly on the diesel and generator maintain costly .

Learned from the EV car concept , we customized a solution solve client pain points . By use generator + lithium battery storage solution improve the power efficient to save diesel cost . With caculation , within one year , lithium battery cost can be get returned .

Brighten have a formula to exactly calculate how much power consumption for a certain LED Screen running in a full day . The sunny time , sunset time , sunrise time and night time power consumption level is different , Brighten have auto brightness control system to auto adjust the brightness level as per outdoor environment . Energy saving need a system support . In the area without electricity , every watt matters to power the LED Screen . If calculated the sizes (length * height ) * running time , it is a big figure start from 1 watt .
