1,000 watt vs. 1,500 watt Pure Sine Waive Inverter

Other than cost is there a disadvantage in using the 1500 watt ?
Amazon is sold out of the 1,000 watt.
I am in process of setting up the basic build for a 1,000 to 2,2000 watt system and trying to use the parts recommended on web page.

Well the obvious advantage is that you can power bigger loads.
Aproximately 500 watts bigger.
Perhaps it may draw more idle power but I can't say for certain.
Could you provide links to these Amazon products so that we can all see what we are dealing with?

The link is below for the "Out of Stock" 1,000 watt system and the alternative 1,500

nothing wrong with the 1500,better anyways.

Is this the system blueprint your're referring to?

I noticed the 1000W cables included with it are “8gauge to support 1000W”
...
Um... no.
1000W is 83Amps at 12v, and you BETTER have #4 minimum, #2 preferred...

So, neither is likely to be a great inverter...

probably ok, sustained around 400W...

Well... the picture shows twinned conductors, so, if both are #8, it should almost handle 1000watts... silicone 105C wire will flow 83 amps, but have high losses...

well,i assumed he would make better cables.factory cables are crap.

I wouldn't even trust those cables to hold my pants up.

In general I prefer to go bigger with the inverter so there's less stress on the components when handling smaller loads. This tends to keep the fan from running as often (can get annoying in small spaces).

That being said, the two concerns I have in going from the 1000W to the 1500W inverter for this blueprint are:

1) The wire size needed for the 1500W inverter is larger than for the 1000W inverter (covered by others already above). So make sure to get the correct gauge wire for the inverter rather than whatever is noted in the blueprint. This means you will need to size your fuse appropriately for the larger inverter as well.

2) The blueprint includes only one 12V battery, which is likely why Will capped the inverter at 1000W. 1000W/12V = 83.33A and the single Battle Born can handle it since it's rated for 100A continuous. If you keep to loads of less than 1000W when using the 1500W inverter, you are all set. However, if you want to run loads at 1500W you'll need to add another battery in parallel. 1500W/12V = 125A which is beyond the continuous rating of one battery but with two in parallel each battery will only need to supply 62.5A.

Biggest difference: battery connector arraingment. On the 1000w Tech-On (I have it) they suck! + and - dang near touching each other with no shield like that 1500w GoWISE. The Tech-on is great through, has survived 2 summers 110+ F unshaded on the doghouse of my motorhome and never quit due to overheating- I just use solid core #8 to connect to the battery since I never use 1000w loads, at most 400 watts. Plus it uses only 0.9a to power itself with the fan off- figure another amp when it's on.

Huge edit: Power Tech-On is I guess now GoWISE- same inverter just different name. yikes.

Have you considered Giandel 1200w? https://www.amazon.com/Inverter-120...?keywords=giandel+1200w&qid=1582581301&sr=8-2

This past weekend I installed a RENOGY 2000w PSW inverter in a brand new Kenworth tractor.......Real nice inverter!

In my camping trailer I used the GoWise PS1002 Pure Sine Wave 1000w.....Works fantastic and I really tried to beat it up as a test. Running my 1500W heat gun and it passed the test...$139
