DEYE 6K Hybrid Parallel SP No Battery

[duncanaval]

I have 3 x 6kW Hybrid inverters connected in a parallel single phase arrangement without batteries.
The Each inverter has 7kW (21kW total)
Inverter #1 is set as Master M01 with CT connected pointing to inverter
Inverter #2 is set as Slave S02
Inverter #3 is set as Slave S03
Original network cables connected to can ports daisy chained M01 to S02 to S03
Units program for No Battery in battery setting (Batteries are not available)
Load Line (UPS) are not connected
Problem
When set to parallel mode the inverters are all showing grid power coming in equally shared but the off grid X is indicated on display.
The units are synchronizing and producing PV power out.
Each inverter is working in non parallel mode when tested individually (CT moved to each inverter made master).

Where did I go wrong

I may be wrong, but I didn't think that they could work in parallel without a battery.

This ^^. Paralleled Deye/Sunsynk/Sol Ark MUST have a common battery bank.
Even said so in the blue Deye manual...

Where you went wrong is not buying batteries.

YOU CANNOT AND SHOULD NEVER RUN THE INVERTERS IN A PARALLEL STACK WITHOUT COMMON BATTERIES.
this can and will damage them, this is also very clearly state in the manual

Thanks for the feedback. I did not find this information anywhere in the manual. If you do have the time please share this for my reference.

Batteries arrive next week. I never saw this information in the manual but I am guided accordingly. Thank you
