20 Amp MPPT Solar Charge Controller

MPPT2075-DCLiR is a sort of 20 amp MPPT solar charge controller.

It is fit for 12V/24V system voltage, 20A maximum charging current, 260W/520W maximum load power, Output voltage range 30~55V.

Working function:MPPT-DC series is MPPT LED light solar controller within LED driver.Constant current output and increase battery voltage to suit the light working voltage.

MPPT-DC series with advanced street light control function.The modes of lighting can be set according to customer’s detailed demand.That is the advantage of this kind LED light solar controller.

1,from dusk to dawn.

2,five-stage night modee,you could sent time 1 to time 5

3,TOT mode,set the light work on time before morning coming.

Above all working time could set dimming 0~100%,that save energy to keep light working longer time.

This street light solar charge controller could be set data,read status and read data by Infrared remote controller S-UNIT.

1,set work time,dim,battery type,voltage,light current and so on.

2,read status,if you find light not work well,you could using S-UNIT to find the reason,fault.

3,read data,battery/light/panel voltage,over discharge times,fully charge times,some days highest/lowest voltage and so on.

Now,please find LED display explanation as below,

1,Green LED

  On-----solar panel is correctly connected,but not charged

  Fast flash(0.1/0.1s)-----MPPT charging

  Flash(0.5s/0.5s)-----Equal or Boost Charging

  Slow flash(0.5/2s)-----Float charging

2,Yellow LED

  Off----Over voltage protection

  On----Battery is normal

 Slow flash(0.5/2s)----Battery voltage is low

 Fast flash(0.1/0.1s)----Low voltage protection

3,Red LED

  Off----Work normal

  On-----The output power is 0

  Super slow(0.2/5s)----Open circuit protection

  Flash(0.5s/0.5s)-----Over temperature

  Fast flash(0.1/0.1s)----Short circuit or over current protection
