The VE.Direct TX digital output cable can be used in combination with the BlueSolar and SmartSolar MPPT chargers. It supports the following applications:

Solar lighting applications
Virtual load output

Lighting Applications

The cable is designed for lighting applications in solar energy systems.
Energy consumption can be significantly reduced by the ability to dim lighting when needed. Lower power consumption will reduce the overall system cost. Also, the availability of the lighting will increase, even in case of a partially charged battery in low sun.
The cable connects the TX output of the VE.Direct connector of a MPPT charger with the PWM dimmer input of the LED driver.
Virtual load output

The cable is designed for adding load output functionality to the larger MPPT chargers (MPPT 100/30 and larger) that do not have a load output. The cable connects the TX output of the VE.Direct connector of a MPPT charger with a battery protect or a solid state relay to switch a load on or off.
