wire thickness

I'm sure answers are on here somewhere but...Ihave 2 bats and an inverter. I plan on using #2 from inverter to 1st. bat.
Do I use #2 to connect 2 bats in parallel?

In short, yes.

I bought two pre-made 3' long #2 invertor cables at a truck stop that already had the heavy duty copper eyes crimped in the ends to connect my two batteries together. I used a second set to connect my 1000w (2000w peak) invertor to them. These cables are braided flex and are able to handle more current with less voltage drop and have a super heavy duty jacket.

Depends on the size of your inverter Dennis.. I have a 2000 watt 4000 surge inverter and use 00 wire from the batteries to the inverter and 0 between the batteries..

Understood as... whatever size wire thickness is used to inverter should be same between 2 batteries... right?

I have 4/0 welding cable from my inverter to the batteries & 2/0 in between the batteries for the series/parallel connection. My inverter though is 3,000 watt continuous, what is your inverter size?

Haven't got one yet. Looking at a 600watt pure sine but don't know
yet.
Any suggestions on brand?

Shouldn't that be the other way around? I would think you'd want the#2 going into inverter.

The most critical in terms of reducing the resistance, is the wire size between the inverter & the batteries. #4/0 is much larger than #2/0. #2 is smaller than those and is standard automotive battery cable size. I'm using custom length, made to order welding cables.

I have been very happy with my Magnum Energy inverter.. best advice I can give you is to get a bigger one than you think you will need.. it cost more to upgrade later on...

I will say that Magnum Energy makes a very amazing product. They are seemingly bullet proof and their tech support team is extremely quick to respond and easy to work with. That said, I have a Xantrex 1,000 watt for sale.
