I'm running off-grid at my cottage (don't have a choice)
5x 50Ah 12v batteries...1000 Watt inverter...and 1x (for now) 60 Watt Solar panel...
I only use to power a maximum of 8x 9 Watt lights and a TV/DVD... I need to consider that I will need in the near future a on-demand pump for water but that's about it!
I just don't want to start a fire!!! My cottage is wired like a real house (120v...) and I plug everything in the inverter... Just want to know if I really need to go to #2 wire size between batteries and between inverter??? Any tips you have would really help!
Everything's been working fine for the past 3 years... There's a daughter now in the picture and safety is #1!

Your inverter should be very close to your batteries so the length of #2 shouldn't be a cost issue. How far did you plan to run the #2 wire?
Run the high voltage (120v) line the longer distance as it requires much smaller wire.

Ditto Mike. The inverter should have had minimum wire sizes for different distances. In my book it is best to use a size larger than their minimum.
#2 wire should carry the expected load out to 12 feet max, more or less. #4 to 8 feet, #6 to 4 feet
