VE.Direct TX digital output cable

2. Solar lighting function

In this section:

The cable can be used in lighting applications in solar energy systems where energy consumption can be substantially reduced by dimming lights when appropriate. The resulting lower energy consumption will reduce the overall system costs and will increase light availability, even when the battery has only been partly charged due to bad weather.

The cable connects the solar charger VE.Direct Tx pin to the PWM light-dimming terminal of a LED driver.

Connection sequence:

  • Connect the VE.Direct connector to the solar charger VE.Direct port.

  • Connect the white Tx terminal to the PWM dimmer input of the LED driver.

  • The black ground terminal is optional or is not used.

Wiring example - Controlling a streetlight LED driver.

Configuration items in the solar charger settings in the VictronConnect app:

  • Settings > Tx port function > Tx port function = "Light dimming (normal)" or "Light dimming (inverted)".

  • Settings > Load > Load operation mode = "BatteryLife algorithm" or any mode you prefer.

  • Settings > Streetlight > Streetlight function = "ON" and set up the timer program as desired for your application.

  • See the solar charger manual for more information on these settings.

The PWM dimming function has been tested to work with the following LED drivers:

  • RECOM RBD-12.

  • Glacial Power GP-LD7048-0B.

  • Glacial Power GP-LD3548-0B.

  • MEAN WELL LDH-45.
