Morning,

If I install a Renogy 2000w Inverter do I need to put a fuse on the live feed between the battery?

Yes.

What size type would I need?

Also what size cable would you recommend to use?

I would expect the installation instructions to give guidance on this.. This sizing calculator and guide will tell you what cables you need.

Also what size cable would you recommend to use?

Cable size depends on the length of the run and the power requirement of the inverter. Calculators are readily available online.
Normally you will get a recommendation from the inverter manufacturer saying "Unit x @ 2000w peak output requires a 150A fuse". For clarification that is an example not advice.
I would read the manual and do the calculations, fitting an inverter is not a simple plug in job unless low powered so not to be diy fitted unless you have experience of this kind of stuff. Different cable sizes require varying connections that need crimping... a skill in itself.

Out of interest, I've just looked at the Renogy 2000W Inverter Manual. See Link Below.

Its not very helpful!

2000/12 = 166 Amps nominal

The manual says it ships with 2 AWG cables, 2 feet long. Later in the manual there is a table stating the maximum Current for 2 AWG cable is 130 Amps.

The advice about fitting fuses is a bit vague too.

Ive got one. Their cables are probably inadequate, light duty lugs etc. I used my own and over specified with 50mm2 cables, 30cm run, with 250A fuse. Fuse essential with these currents. Unless you have heavy duty crimping tool you will have difficulty making up cables but they can be got made up to your sizing - e-bay etc

I recently fitted a 3000w inverter as there wasn't a massive amount of difference in price. The cables that came with it though were supplied as two cables for each of the pos and neg connections. I found it a bit difficult to fit the cables as I have other connections to the battery, so I fitted a 35mm welding cable instead (150mm long approx) and a 200A fuse

2000W is a hefty inverter, needing big cables, large fuse and big battery bank to power it. Many of us get by with a much smaller inverter.

However, I found that, after 'progressing' from a 1000w - 2000w and finally to a 3000w, i can now power everything I want to power, and at the same time (within reason of course), but as you point out many people manage with a smaller inverter and modify their usage accordingly and are more than happy.

It would have been cheaper for me and less time consuming to have gone for the 3000w inverter from the start!

We have the Renogy 2000W inverter. The fuse in the line is to protect the cables from overheating. The highest load we will put on it is 1600W. I used 40mm2 cable and a 150A Mega fuse.
