Are there any documents for the ve.bus backup and restore feature within 3.60?
We just tried it and it shutdown the inverters, there was no warning or info that this was going to happen.
It is literally just released. The restore will obviously restart the system as any config upload does, the backup shouldn’t, that I tested myself in beta testing.
Could you clarify your setup and what action caused the issue?

Split-phase ESS Dual Quattro 5k/48V 120V, Cerbo Gx mk1
I upgraded to 3.60 this morning, and tried the backup feature only.
It took a minute or two, and the inverters were put into PassThru mode (I have grid).
PV from 250/100 and 250/70 was disabled.
Maybe 10-15 seconds after the backup was complete, everything came back up on its own.
I can imagine off-grid people would experience an outage.
Probably needs a warning.
I should have said we only tried a backup. Inverters went offline, no status on the device list.
Its 2 MPII 5k in parallel with ESS.
It might have only just been released, but documentation should be released along side it. I didnt try the feature during beta.
Agree, just docs do tend to follow especially on new functionality. Some will be mentioned in the release powerpoint.
It shouldn’t restart on a backup.
I will run this up the flagpole.
Please share a site ID (just the numbers in the VRM URL between installation and dashboard).
thanks
Here you go 169174
Any mods or customisations we need to be aware of?
Nodered is running but the only changes to the system that it makes is to an EVCS. It does read various other parameters and sends them to other systems.
Are you 100% sure that the system actually went into passthru or shutdown and PV (from MPPTs) was disabled ?
What I’ve noticed from the betas is that taking a backup sort of locks access to the devices (like a firmware update scan does) so the device status reporting might be off during the backup.
A backup shouldn’t shut down the inverters, a restore might trigger a reset.
Thats not an issue.
The process shouldn’t be any more disruptive than downloading a config via VRM. As per Bart’s query, the system did physically turn off, it wasn’t a case of the display timing out?

The inverters were no longer powering the house, the grid was. You could see this on the grid tile as well as the graph
As stated: since the backup process “locks” access to the inverters, no other control messages can be sent to the inverters during the backup.
This can cause them to go in passthrough mode but shouldn’t disconnect the loads.
I ran a backup now, grid disconnected. It ran fine while inverting. In an ESS, it will go to passthrough, much like it does when you update the GX, due to lack of comms and devices being locked.
I could see the state moved to “off” though it was on and no loads were shown. Normal for downloading a config.
I have flagged this though and asked about the manual.

OK, I just did two more backups at 1105 and 1115 EDT and watched the Quattro LEDs.
I do not have a problem with this behavior at all, just documenting it.
Initial State
L1 Master: Mains On, Bulk On, Inverter Blinking (Normal ESS Behavior)
L2 Slave: Mains Blinking, Bulk On, Inverter Blinking (Normal ESS Behavior)
During Backup starting at “Querying”
L1 and L2: Mains On Only
After Completion
Back to normal ESS behavior.
Thanks, it just needs a warning to let you know this is expected.
When you press backup, and then the next minute the inverters are showing as off and there are no details, you start to wonder what is going on.

Hi we’ll look into that.
Thanks for the report.
Meanwhile @dansonamission can you rephrase your first post a bit. For an offgrid company like ourselves, “shuts down the inverters” makes all alarm bells ring. As that usually means powering down the house.
Thanks!
