quick and easy inverter question
Does the size of the power inverter make a difference in the draw from the battery? Meaning, if I am pulling 300 watts through the inverter, will it be the same draw from the battery regardless if its...

My Magnum 3000 has an idle draw of 30w while their 600w inverter draws 10w at idle. However my Magnum 3000 has highest efficiency under load at about 550w draw (90%).
So it does help to use a smaller inverter if you let it idle, but I rarely let mine idle, if I don't need 120v I hit the inverter button on the remote to shut it down completely.
I have propane fridge so if off grid I don't need to let it idle to keep fridge on, even if I did my 300w solar would easily provide the 30w idle power along with other stuff.
I could also do search mode to reduce idle draw to 8w but that causes my microwave clock to blink on and off.
