Hi all..
Rather than running electrics out to my shed for modelling use, I'd like to use a 12V Car battery and a 12V invertor to power small modelling tools. I also intent to use a 12V Solar panel to charge the battery but are inverters hungry monsters in relation to what they require from a 12V Battery.
If so, what calculations can I use to determine the ampage of the battery I would require to power the invertor satisfactory to give me sufficent time in the shed.
I've used Uninterruptible Power Supplies at work for computer use but they are more for supplying a specific amount of power for a short time to allow the computer software to shutdown the computer servers until normal line supply is established. In saying that, the 2 Batteries in the 700W UPS I have are only 7Ah which gives me up to 20 minutes (from what I remember).
Also, can the solar panel be kept connected to the battery whilst using the invertor or should it be disconnected?
Regards
