Low Voltage Sensing Relay -- HELP !!

You need a circuit like the one on:

That's interesting. I have a similar requirement, to drive a low power
fan (draws approx 180mA) whenever the battery is receiving charge from
a solar panel. For this it makes no sense to use relays. If I flip
the connections to the comparator, does it then bleep above the
threshold voltage ???? How much current can the circuit take - ie
could I then power the fan directly ??
You can probably detect that my understanding of electronics
is at the vodoo level !
Thanks
