EG4 PowerPro Firmware

Goin'Solar · May 29, 2024

So I think I need to update my firmware between my 4 PowerPros since the 2 new ones aren't communicating with the two older ones. The new ones are on BMS Version Z02T13, while the two original batteries are on version Z02T01. The firmware on the EG4 website is version S02T09.

The version lettering/numbering is confusing and I haven't found a list. Which version is actually the newest? S? Z? T09? T13? Is there a list/changelog posted somewhere?

I'd be pretty sure the one on the website is the latest recommended version.

I'm not so sure of that.

In the past, the 18kpv firmware on the site/in the updater was outdated.

Yeah I wouldn't put it past them. But I would just install what's on the website on all of them anyway myself and see if I hear otherwise after that.

Here is the link to the latest firmware update on the all-weather PowerPro battery. After the firmware update on the batteries you should see Z02T17. All indoor WallMount batteries are shipped with the latest firmware and there are no current updates.

That firmware mentions it is for remote update. Are you 100% sure this is the firmware to use with the RS485 to USB cable? @EG4_Eric

Yes, I'm certain.
