lately around where i am the power has been going out for long
periods (its the local power company) anyway i was thinking of having some
sort of 12v backup supply to drive some things on 12v when power is out any
ideas on the best logical way, i did think solar panel some how to car
battery but not sure
Re: 12v backup power supply
Some of the cheep UPS have one side of the battery
at mains potential !. that is why they are sealed inside the
case. Check to see if this is so.
I added a large battery on to a ups so i could un plug and use the computor
during thunder storms, great idea untill
i conected some gear directly to the 12 volt external battery and BANG.
Lucky it was earthed, big sparks and
the mains fuse popped.
