A typical use for the load output is for a well pump. The well pump will run from the battery as long as the battery is charged. After the sun goes down and the battery starts to run down the load output will turn off and the well pump will stop.
This feature is found on the following Victron MPPT Charge Controllers
Like everything else on these charge controllers the load output can be configured. Its easiest to do with the Bluetooth charge controllers but can be done with them all. Here is an excerpt from the manual:
3.6 The load output
The load out output can be configured with Bluetooth or via VE.Direct.
Alternatively, a jumper can be used to to configure the load output as follows:
No jumper: BatteryLife algorithm
(see manual for more details)
Jumper between pin 1 and pin 2:
Automatic load reconnect: 13,1V or 26,2V
Jumper between pin 2 and pin 3:
Automatic load reconnect: 14V or 28V
Programming the load output by Bluetooth is even easier, a screenshot is below:

I’ve used the load outputs for various uses on different projects... One example is using the solar irradiance on the panels as a ‘dusk to dawn’ sensor to switch on an external led light. Another example, was to charge the engine battery or bow thruster battery,only when the sun was shining and the house battery was in float(full)..(additional victron 12/12 9A dc/dc used)
