EG4 18kPV Q+A general thread

I was only shipped the USB RS485 cable, and I can't find the firmware I need to install.
The heater logic update requires a cable I don't have yet. I tried for way too long before I figured out I had the wrong cable.
Do you have a link to the latest firmware (RS485 style)?
Can you post a pic of the usb rs485 cable I don’t think I was shipped one

Is there a typo in the labeling? Don't these have heaters/below freezing charge capability?

The cells still need to be above freezing.
I did a full restart of the inverter thinking something similar with no luck
Yep. And a few different cables. No luck

RS-485 is just not that complicated. It's a brain dead TWO (2) wire serial connection that can be run in parallel. You don't need the ground. . .
$12, Electronics toolbox item. Sacrifice an old Cat-5 cable Should be 1-8: ORT-ORG-GRT-BLU-BLT-GRN-BRT-BRN
Download the tool from eg4electronics.com, plug into your laptop, ORT-(B-) ORG-(A+) (verify pinout is 1-B-, 2-A+, if wrong swap the wires, it can only be one way or the other) verify the batteries are talking, get the readings from the tool, then use the tool to upgrade all the batteries.
Once you have confirmed the pins get an RJ-45 screw lug
snap it into the inverter in the battery hole. Verify the pins, I think it's 7-8, So ORG-7,ORT-8. You just spent $5000+ on a bunch of hardware, spend an hour and figure it out. Once you have the pins nailed down crimp a cable, or build a pigtail into a biscuit jack, and run a straight thru cable back to the batteries.

I've crimped plenty of cables. I can't even find the firmware files anymore so I can't even get started trying to update.
The firmware situation on these batteries is a bit of a mess. I do hope that's my fix..

What are the IDs on each battery?

I did on the ID-1 "master". I didn't on the second one but the manual says you don't need to.
I've had the first battery up and running without issues for months
Maybe try it regardless, it shouldn't hurt. I'm on LLs but changed all mine.
Another dumb question/thought incoming.
The PowerPro batteries have an internal bus bar.
My "old" PowerPro battery with the older firmware has the dual 2/0 wire connections made from it to the inverter.
I want to see if the newer firmware on my "new" PowerPro will fix my issue of the second PowerPro not being detected/communicating, but I don't want to move the wires from the old PowerPro to the new one (those freaking conduit boxes have to be removed to connect/disconnect the cables, and I don't want to do that).
Can I safely just make my "new" battery the "master" without changing my wiring, move the coms cable to the new battery and connect it to the 18kpv, and see if that fixes my issue?
Since it's on an internal bus bar it shouldn't matter? Right?

Yep you can do this.
