SMR-MPPT1575 is a sort of 15A 12V/24V waterproof MPPT solar charge controller.
This sort of tracer solar charge controller is fit for 12V/24V automatic recognition as well as 15A charge and discharge current.
Lumiax solar charge controller are exported to all over the world.With the development of solar energy,Egypt government and South Africa government supply enough support.
12V 24V MPPT solar charge controller are our star products.Basiclly speaking,there are two kinds.One has LCD display,another has LED display which is waterproof and glued product like above picture.Actually this kind item have two series,we named SMR-MPPT and MPPT-DC.They both could be used in solar street lamp.What are the difference between them? SMR-MPPT have no LED driver in side,so it outputs constant voltage to lamp.And MPPT-DC within LED driver have dimming function,0~100% programmable.It outputs constant current to lamp.0.15~4.0A programmable.How to set it? Remote control S-UNIT with green colour do this work.S-UNIT also could set other parameters and read the controller work status together with fault.For SMR-MPPT series,when it is installed to solar street light,S-UNIT could set 5 working stage at night.it also could be used in 24 hours solar system.Some customers use it in RV.
In order to supply customers the best MPPT LED light solar controller
.We have 3 simulation equipments in our lab,we test our MPPT tracking effiency up to 99.9% and charge conversion effiency 97%,discharge conversion effiency 96%.
For 12V system,the maximum panel power is 200W and for 24V system,the maximum panel power is 400W.Maximum panel voltage is 55V,battery voltage is 35V.
Actually,it your panel powe is over our limit,it won’t burn the controller,because we do protection function on it.But just waste redundant energy.
