Asked by peter

12.50 volts on battery but when i connect to a microwave of 400w or 600w or 800w it makes a continual beep. Also if i connect i t to 1200w vacuum it beeps, but not when connected to a 750w toaster.. It works on every appliance but it beeps every half second,, any idea why please. also battery voltage afterwards didnt go down much but it was only on for a minute or so

Answered by Andrew Harris at RoadPro on September 01st, 2020

12.5V is a low voltage for a battery and is not sufficient to drive an inverter that's powering a microwave oven or a 1200W vacuum cleaner. It may be just enough to power a toaster. For efficient performance of the inverter, you need batteries that can cope.
