Deye sun (SUN-8K-SG01LP1-EU) Phase on both cables?

[ctuhkwm]

Hey all. I recently installed Deye sun inverter as backup power supply.
And i got into a problem.
as soon as the inverter starts working from the battery, its output “possibly” has a phase on both outputs ( N and L)
but if it works in bypass mode - all great.

Is that how it supposed to work? Or no. Cause i'm very worried
I would be very thankful for any help



P.S
(I did the test in the outlet just for the photo because it’s dark there
on the load contacts of the inverter - the same thing.)

Spoiler: pictures

Hello!

So it should be. You now have two phases.

The main thing you need to achieve is to trip the RCCB
You have two options:
1) If you want a system with one phase - use Signal Island in the settings, connecting to the appropriate outputs (it seems the last two)
contactor that will connect N and PE in off-grid mode (this is recommended)
2) Leave it as it is, but be sure to ground the inverter housing.

After grounding the inverter housing, the RCCB started working correctly for me on both phases.

I am currently operating the system in the second mode.
