Solar Street Light

SOLAR STREETLIGHT USER GUIDE.

1. Setup time operating.

SW -A:  setup the hours for the Streetlight is ON in previous time after sunset.5 minues

SW -B: setup the hours to wait the second time Streetlight is ON

SW-A and SW-B positions:

SW_A: Setting timer for lights on the first time

SW_B: Setting timer for lights waiting the second time

            Turn on until the morning

Example:  possition setting: 

It means after 5 minues from sunset the streetlight will be turned on during 2 hours (SW-A), then off for 1 hour (SW-B) and turned on again until sunrise.

2. Operation via  Solar Voltage:

a) Vsolar: on strong sunshine:

 Three modes of charging can be used:

          Boost charge: Max. 10A/ constant current

          Float charge:  13.8V/ constant voltage

          Re-boost charge: 13.2V

b) Vsolar: on weak sunshine:

  Turn off charger, if load is ON, turn it (the load) OFF after 2 minutes.

c) Vsolar: at nighttime:

  Starting to count time:

·         After implemented 5 minues DELAY time: if Vbatt. >11V then turn load ON.  Max. load current:  8A . The light will works following your setting by SW-A and SW-B.

Notes:  if while LOAD is ON and Vbatt. <9.5v, then turn the load OFF. When it’s sunny again, reset the cycle.

               FULL mode:           14.5V/13.2V

               LVD mode:                9.5V/11V

3. Display modes:

 

- Source Led:     when turning the main contact, the light will be on.

- Charging Led: when it’s sunny, the light will be on to inform that battery is charging.

- Full Led: informs that the battery is full. Led is ON when Vbatt. > 14.5V. Led is OFF when Vbatt. <12.7V.

- LVD led: informs that the battery is empty. Led ON when Vbatt. < 9.5V. Led is OFF when Vbatt. >11V
