+## What is a Solar Router ?
+
+A _Solar Router_ allows to redirect the solar production excess to some appliances instead of returning it to the grid.
+The particularity of a solar router is that it will dim the voltage and power sent to the appliance in order to match the excess production, in contrary to a simple relay that would just switch on/off the appliance without controlling its power.
+
+A _Solar Router_ is usually connected to the resistance of a water tank and will heat the water when there is production excess.
+
+A solar router can also do more things, like controlling (on/off) the activation of other appliances (with the grid normal voltage and not the dimmed voltage) in case the excess reaches a threshold. For example, one could activate a pump, pool heater, etc if the excess goes above a specific amount, so that this appliance gets the priority over heating the water tank.
+
+A router can also schedule some forced heating of the water tank to ensure the water reaches a safe temperature, and consequently bypass the dimmed voltage. This is called a bypass relay.

 ## How routers work ?
 
 To chose a good router, you need to know how they work.
