question

Have you tried the following:

• Connect the BPP2 panel while making sure you connect the last (or first) Quattro to the VE.bus Connector on the BPP2.
• Does the VE.Bus system show up in the device list of the BPP2? If so navigate there and turn the system on via the BPP2 menu?
• Are you using a VE.Net battery monitor? Is this battery monitor plugged into a VE.Can connector on the BPP2?
• Has there been a firmware update of the Quattro system recently? Newer firmware might be incompatible with the BBP2.

If all fails consider using a CCGX panel instead.

didnt realise had had a reply - Appoligies

. was connected at the end of the daisy chain yes

. didnt try that - on site tomorrow - will have a look.

. battery monitor connected on VEnet

. Yes intending to fit CCGX tomorrow - better genny management etc,. etc.... Wondering if to try and keep the battery monitor in the system though..??

I've seen something similar but not the same as your problem on old Quattros with very old firmware v1xxx. These were standalone units though 1 phase with a generator as the only AC supply. When we plugged in any ethernet cable to the the VEbus ports, the Quattro would shut off for around 5-20 seconds. It was a few years back so I can't remember 100% what would happen next. One of two things. Either they came back on by themselves after the 5-20 second delay...or they wouldn't come back on at all until we removed the ethernet lead. We were only plugging in to change/ check voltage settings using MK2 programmers so it didn't really matter but it was annoying because our stations are totally off grid and plugging in would kill AC to the station while we were doing the programming. On some stations this would also shut down the generator which is 6 floors of stairs down (lighthouses) I wish I could remember if they came back on by themselves or not. Sorry it was ages ago...A firmware update to latest 1.xxx completely fixed this issue and we updated all of them so can't go and test I'm afraid.

Hi guys did anyone find solution for this I have a similar problem on a boat where the quattro shut down when connect to VEbus and will restart if you disconnect.
