I need about 100 feet of cable from my Inverter to some TV, IP surveillance camera VR, an internet switch and 2x 9 watt lights bulbs about 400 watt load. Should I use a 12 gauge solid 2 conductors and ground? If 50' or 25' is my maximum distance to use any ideas of how to carry my stored electricity to these units? Thanks.
Acceptable Distance from 1500 watt 24 inverter to Load

A voltage drop calculator will help you figure this out. If you were running 1500 W @ 120 V, that is 12.5 A. Over 100 ft of 12 awg, you'd lose 4 V, more than 3%. If you are only running 400 W, the loss would be less than 1%, but why have such a big inverter in that case?CS6P-260P/SE3000 - http://tiny.cc/ed5ozx -

How did you get 4 V lose and over 3%? With the same factors the Voltage Drop Calculator gives me:
Voltage Drop = 1.99
Voltage Drop Percentage = 1.66%
Voltage @ the end = 118.01
Oh, I got you, you did single set of conductors and I did 2 conductors per phase in parallel.
If I go to 90 feet I'm under 3%, I still achieve acceptable results!
Let me tell you guys something more interesting:
I measured the volts that I get from the outlets on the inverter and I get 107 volts not 115 like the POCO. Now, I connected the 100' long 12 gauge cable to one of the inverter outlets and I get at the end of the cable the same 107 volts. This shows no loss of voltage at all.Last edited by john95; 08-31-2017, 09:29 PM.Comment

I'm more interested in why only 107 VAC on an unloaded outlet - but I know nothing of your inverter voodoos.Comment

Update: In turned out that I have been getting perfect 110 AC volts from my 1500 watt inverter and at the end of the 90 foot cable and not 107. I got a true RMS meter and have a more accurate measurements now.Comment
