Solar Street Light Controller 12V 24V Auto Charge

One controller for the whole lamp system

• Charge and discharge handled automatically

  An MCU manages the solar input, the battery charge and the lamp load in one loop. Protection functions stay active the whole time, so the pack is not pushed past its limits on a long cloudy run. The charge and discharge parameters can be adjusted on the unit itself, which means you set the thresholds for your battery and leave them alone.

• Read the battery state at a glance

  The large LCD shows battery voltage and Ah next to solar and lamp status icons. You see whether the panel is charging, whether the lamp is drawing power and where the battery sits, without a multimeter. That readout turns a guessing game into a two-second check.

• Lamp timing that sets itself

  The built-in timer and the light control with delay run the lamp from dusk to dawn without manual switching. Set the delay to match your site and the lamp follows it every night. The same unit supports lead-acid and lithium batteries, so one controller covers the packs you already run.

Wire panel, battery and load in sequence

1. 1
   Mount the controller

   Fix the unit through the wall-mount flanges on either side of the housing. Keep it near the battery box and out of direct water runoff.

2. 2
   Connect the solar panel first

   Land the panel cable on the terminal marked solar panel. Tighten the screw so the wire cannot pull free.

3. 3
   Connect the battery

   Land the battery cable on the battery terminal. Confirm the polarity matches the battery before the screw goes down.

4. 4
   Connect the load last

   Land the lamp cable on the load terminal. Connecting the load last keeps a loose wire from sending power to the lamp while you are still wiring.

5. 5
   Check the screen

   The LCD should show battery voltage and the solar and lamp icons. Set the charge and discharge thresholds for your battery chemistry before the first full cycle.

From a dead lamp to a managed battery

The lamp that went dark

A lamp that fails after dark tells you about the battery only after the street is already black. Installers often find out from a complaint, then spend a morning on a ladder and a second morning sourcing a replacement pack. Fixed cutoffs and plain timers do not adapt to the chemistry in the box, so the fault hides until it is expensive.

One controller, fully in charge

The MCU reads the solar input, sets the charge profile for the battery and switches the load on and off on schedule. Protection functions stay active through every cycle, so overcharge and over-discharge are handled by the same unit that runs the lamp. Lead-acid and lithium packs both sit within its range, and the voltage settings can be adjusted to match the pack you install.

Installed once, checked in seconds

The LCD shows battery voltage, Ah level and solar and lamp status at a glance. Check the screen before you climb the pole, then confirm the lamp switches on at the set time. Verification takes a minute at the base of the pole, not a return visit the following week.
