my inverter is only givin out 215VAC whatever the input voltage is. however, if i plug my monitor in it makes a weird noise (similar to a transformer supplyin a large load), and lines appear accross the screen. also, if i plug the UPS into it, it still stays in battery mode rather than switch back to mains. i have checked the manual for the UPS and it says it will go to battery if under 180VAC, i dont have the manual for the monitor tho. could the problems be due to the lower
the inverter is an 800W modified sinewave
