G'day Luis, It is so that the module can be used in solar-powered night lighting. An undervoltage disconnect is often included in the module. So the lights will go on at sunset, and go off either at sunrise or when the battery voltage is low, whichever happens first. Loads that do not need to be switched or undervoltage protected can attach directly to the battery. On Wed, Sep 16, 2015 at 08:05:45AM +0100, Luis Moreira wrote: > Hi James, > I'm a bit confused...
