Hi Fellas,
Looking for some sanity as to why a venus would drop out of connecting to VRM after the charge current limit in DVCC was put to 0A
Green LED is lit.
The longer story
Multiplus II / 3x Pylontech U3000 with Venus GX (backup only)
Got EL tripping last few weeks and hunting why, noticed that when the batteries are at 100% & the new algorithm is doing its thing that my EL tripping seemed to be occurring around the time the charger must have started charging SO to test if it WAS in fact the problem i went into DVCC and set the charge current limit to 0A.
Now i got no comms to VRM & i’m in the middle of the Atlantic ocean for another week.
Had the missus reboot the venus, still no comms.,green LED is on.
Connection to VRM basically dropped away the same time i changed that setting.
Anyone hit this before?
Unfortunately i cant do anything onsite for now.
There is an issue being worked on where bad network connectivity causes the ordering of log messages to be messed up, and then sometimes VRM loses the critical “tunnel” information which is needed for the remote console to work. When I say it is being worked on, I mean it is almost entirely solved already.
It mostly affects GX devices on LTE modems, where the network connection changes late in the boot sequence.
If your earth leakage trips, it very probably has nothing to do with how the inverter is charging. I would suspect that you have a real leak, or that your standing leakage (it is normal for modern appliances to leak small amounts, and it adds up) is around the nuisance tripping point already, and the inverter adds just enough when charging that you start to get tripping.
The AC->DC conversion is isolated, so it makes zero sense that DC charge current can affect an AC leakage.
If you give me a VRM id, I can check to see what I can see…
Hi Plonkster, yes understand what your saying. Have tried switching EL from a Schneider to that Hagar that is supposedly marketed as more nuisance trip free but the EL is tripping regardless.
Since i put that charge current at 0A the tripping has stopped.
PMed you the Id no - no fresh data there since 1pm yesterday tho.
Split the house into two parts, each with their own RCD (aka EL). The standing leakage in modern houses is too high. Every darn new appliance leaks 1mA these days, and if you have 10 of them, your RCD starts to nuisance-trip.
Ok thanks - yes i need to make a plan as i have 101 things running on a fish tank that are also high probability causes, but i been thru trying to eliminate them already & not found a guilty candidate, like you say collectively it all adds up.
For now got a sparky going to go & put the inverter back how it was connected before where it wasn’t part of the EL equation and i’ll get him to put the charge control current setting back to normal via the mk3 whilst there.
Then hopefully the venus will go back online.
Is a fibre router it connects to via wireless for VRM
Shall see once off 0A if it wakes up & connects to VRM again
Sorted, seems the venus just needed a few reboots to actually connect to the router then it was back online.
Inverter no longer part of the EL circuit & no more trips, touch wood. Thanks for your help Plonkster, golden as always.
