Giandel 2000 watt inverter lug size

[Just_Askin]

I am considering buying this giandel 2000 watt inverter https://a.co/d/7o2IrZG
One reviewer says it's a good product, but noted the small lugs causing increased temps where battery cables connect to it. I don't want to have any unnecessary problems. Should I be looking elsewhere? If so, where? BTW I'm using 2 12v 280ah batteries in parallel.

Should I be looking elsewhere

If you use good terminal ends and proper wire you ain’t gonna have issues.

Giandel is decent, as is “Reliable” (QZRELB)

I have a 3000 watt Giandel.
If yours is like mine the pad that the lugs will be in contact with are slighty higher than the surrounding plastic housing.
Therefore the lugs come in contact with a large suface area, although the stud size is rather small.

You can see the contact pad corners behind the inv neg lug.

They use 6mm posts, ( use 1/4" lugs) this actually increases contact area. Dont use the included battery cables.

So, 12v batteries with 2000w inverter, I should use 3/0 cable with 1/4" lugs to carry the 167a with no temp issue?

Should be OK

If you have 3/0 on hand, sure, it will work.

But 2/0 105*C welding cable (depending on length) is still sufficiently oversized for 167A imho.
My 2/0 feeding a 2000W (now 3000W) have never gotten hot. Warmish after an hour of steady high usage, but not close to hot.

Didn't spot you guys were talking about 12V, and was shocked by the cable sizes. I was planning to use 1awg welding cable for my 24V 2000kar.

These babies are amazing, started up a junky "1/2HP" universal motor pump with 22.6LRA, with a 16.6A inverter rating.

The DC lugs are awesome, lots of flat to flat contact area, and the plastic shielding is so much safer than other ones I've seen.

Depending on what model you have, some have built in soft start. It's not listed except for in the manual. It's a blessing and a curse.

Yeah, both my 600 and 2000 have it. The downside is what, extra wear on the motor from extended startup?
I was trying to figure out how it worked. One manual made it sound like it only did soft start if the inverter was turned on with the load already engaged.

I found Variable speed tools and the inverter don't play well at low speed, they just humm.

I haven’t seen that
