EG4 18kpv not recognizing batteries. HELP!

[BrendanK]

Just hooked up my two 6-slot lifepower4 racks, updated the firmware on all of them, hooked them up to my 18kpv inverter, I get 51V at the battery input inside the inverter but the inverter is not recognizing the batteries and is giving a solid orange warning light.
Am I missing something?
HELP!

Alarm status says
BAT COM FAILURE
and
TRIP BY NO AC

You need to use the battery comms cable that came with the inverter. If you need to make a longer one the pin out is in the manual

Battery Pin 1-A Pin 2-B

Inverter Pin 8-A. Pin 7- B

The trip by no AC, you will just need to turn on “run without grid”.

These errors seem to be developing a theme, is this a good default to ship the units with?

Got the “no AC” thing rectified by just switching the default setting. Thanks!
The bat com failure was my bad in making the wrong pinout on a custom cable.
All is well! Thanks everyone!

Some people want the warning if the grid is down. That setting will only silence it

I know this feedback doesn't help with your issue but.. I'd like to offer a suggestion:

The MPPT connections, and load connection.. are both missing the bushing/cap.

Even if you aren't subject to code/inspections/etc, I'd advise getting some bushings. it'll help prevent chaffing the wires, which can pose significant headaches down the road (erratic behavior, shorts, possibly fires) etc. it'd only cost about $2, and 10 minutes of your time.
