Inverter says I have to be a pirate.

My Giandel 24V 2000W inverter users manual says on page 5 under warnings to wear an eye patch.

This will make it harder to set it up but I always wanted a reason to be Captain Morgan.

I suspected you had a Giandel.
Can you please do a couple of tests and report back.
With the Giandel powered off please check for continuity between these points and report back.

Do I need the DC cables connected first with DC power applied or can I just do it out of the box.

Out of the box should be fine.
Thanks.
Two more tests if you please.
dc negative to equipment ground
dc positive to equipment ground

 

[Brewman]

Just got to work, brought it with me to do the testing. Get back to you soon with the results.

Surprised the resistance is that high.

Floating neutral.
It is what it is.

equipment ground and ac hot. Open

dc negative to equipment ground. Open

I guess that is correct.
If it were bonded then you could run the inverter with the dc negative disconnected

dc positive to equipment ground. Open

@FilterGuy please check my reasoning.

<0.5 ohm>

Typical contact resistance. Sometimes you can zero or subtract that if fairly repeatable.
Not everybody has a 4-wire meter.
It would take quite a bit of wire to actually have half an ohm.

My German comprehension is greatly improved but i still am not used to how long the words are...

Back to chit chat after that tech break!

@Brewman, when you wear the patch, maybe you can be my trustworthy foe...
