Hello. This is my first question. I hope someone has the experience to help me. I have a large roll of 1/0 cable. The amp rating is 150A @ 75 degrees F for copper. I need over 200A to hook up an inverter, so my thought is to use 2 cables (giving me 300A) for each hook up point instead of buying more cable of a larger size. Is doubling up the 1/0 cable OK to do? Anyone else do this? I plan on applying dielectric grease between contact areas for good electron flow. Thank you in advance.

If what you have is copper one wire should be enough... I wouldn't use two... But with that said what size is your inverter and how many batteries are you using???

Thank you for responding. I have a 4000 watt inverter and haven't purchased the batteries yet. I am thinking about getting (4) Trojan Solar AGM 6V 375AH and wiring them in series/parallel to get (1) 12V battery bank with 750AH. I will never get close to using the entire capacity of that inverter in the RV conversion. Other forums recommend fusing for the wire size, which brings me back to 1/0 cable is for 150A capacity according to a chart for wiring I found months ago. That is why I thought (2) 1/0 cables = 300A fuse. Which is almost what I would need for the 4000 watt inverter, 360A, I believe. But like I said, I will never maximize that inverter. More like 1500-2000 total watts. |

^^^ That sounds like a great setup^^^^ If it was me I wouldn't have bought such a large inverter because they use so much power just being on... but you have it now...
Your wire and fuse size should be just fine...
How many panels and what size CC??

Your wire and fuse size should be just fine... How many panels and what size CC?? I had no idea that an inverter consumed power even when not in use. I thought it would only take the power it needed during use. My bad. Usually, I tend to oversize items to be sure and also not to run things to their maximum output. I like items to idle away...or at least run slowly. The panels are 400 watt total (4 100W) with a 40A controller (renogy package). Thanks so much for the chart info and your responses. I think I will turn on the inverter when I heat up breakfast in microwave, then turn everything off again (less power drain). Thanks again. |

You have the same set up that I started with all but the inverter... I started with a 2000, But then I bought a 500.. I only use the 2000 when I use my table saw or other large appliances... |
