Hey

I have the Conversol A8 3K, which is identical to the Axpert King 3K

I've connect it to my IMD (IT system, similar to ELD)

And the the IMD trips
Nothing is connected except the inverter...
And the IMD is at the highest trip rating (23kohm,230V)

(An insulation monitoring device monitors the ungrounded system between an active phase conductor and earth. Most monitors work by injecting low level DC on the line and detecting. )

I know about the earth natural bonding when supplied from batteries, and I've searched the forum and saw a bunch of posts and endless discussions about it

But didn't find a definite answer

I can leave the earth disconnected, but the the metal body is not protected

Is it safe to leave it on in the meantime? or I need to shut everything off until I solve it? (Will be left without electricity)

Is there a definite solution? a regulation? a standard on what should I do?

Thanks!
