Batteries are discharging despite solar input being Higher than the AC loads & DC Output
Batteries are DISCHARGING at 444w & Pv is 1175w
DC 0w Ac Loads 413w
have rebooted system components

Hi, can we have a picture of your wiring/system please, also do you have a smartshunt in the system?
And list all other equipment too please.
Yes there is a BMV 712 in it from the old cccx time
the wind generator is NOT part of the system.
AC in is from a Genset
The Orion 48/12 is to a 12v Pump direct from batts used only for pumping diesel & the batt Isolator is to shut it off completely so unnamed can not STEAL fuel when away
at the battery ?
I agree with Ludo but if you have a schematic the would be helpful as you have tucked the wires away and i can’t see where they all go.
will tomorrow But The Battery Neg to Blue dc/dc converter is SWITCH ISOLATED & does Not Connect to anything else
Draws voltage direct from the Battery to run a pump when Not isolated Only so why is this an issue its currently DISCONNECTED ?
You’re negative output from the MPPT 250/100 where does it go?
From your video eventho it say discharging i see the battery voltage fluctuating up suggesting its not being measured correctly but is charging the batteries, could you check that wiring?
This is over vrm, use the remote console for a better picture of what is happening locally.
I am curious though, definitely need a better idea of what is happening here. such small wiring from the battery to the shunt, then the inverter has double that?
Or is that shunt dc power measurement?
Are you sure the shunt is the correct way around?
Hi Dave/Ludo
Have removed dc-dc converter from Direct battery connection
Checked wiring
Neg goes to Batt Neg on Inverter
Pos goes to Batt Pos on inverter
This was wired as per Victron Quattro schematic as was our other system which has been in operation for 9.5 Years
This system was on an old unbranded inverter which we replaced in favour of Victron the Cerbo is 2Months old Quattro is 4 weeks old has been without issue until this week when we noticed the Discharging. this system only Powers several fridges & freezers incidentals & roller shutters etc on polly tunnels if it had not been charging the batteries for long would it not have got below 80% surely as it draws a consistent 2-400w
Remote console shows the similar info although it is normally 12 oclockish before we generate much power on this system
Battery to shunt & shunt to inverter is about the same & 35mm square Cable & properly terminated with Lugs
Have removed the Dc/Dc converter
Only One Neg wire is to the battery
Hi
Thats the AC out to an outside Building
According to VRM either classic or Standard Version its in constant DISCHARGE
According to Attached Display its Charging & the Voltage in Batteries is Increasing see attached
The ohms reading on this & the other neg wires is less than 0.1
I was (retired) a Licensed Electrician So I think I can meter test anything
Removed Shunt Completely took it OUT
checked all wiring & Terminals Disconnected Gen Set
Voltages on terminals Dc & Ac checked
Ohm tested all Wiring
Put Quattro into Battery Charger only (does NOT light up as charging Yet it Is as can be seen in Picture attached look at display charging
Discharge from Batteries stop as expected & charging from solar continues WITHOUT INVERTER LIGHTS
Something is happening with the inverter for sure if the front rocker is not changing anything.
Does it register on the GX as being in charger mode? Is it trying to charge?
Just as an FYI you wiring balance is a little odd.
10kVa uses a bit more cable than 1x 35mm from a battery bank. And your runs are long. (Yes i see the 2x35mm on the inverter itself)
You need to work through the pre rma. Think your system is not behaving as it should be. The next steps will be repair.
Yeah it will but he had DMM being an electrician he can check things with his clamp etc.
The shunt won’t have anything to do with inverter lights.
Maybe no ac in would affect it or an unseated internal comms cable.
Yes the display shows its Charging
35mm Sq Welding cable 125Amp rating
Wire length from charger to inverter 700mm
from inverter to batteries 3.2 meters
No Shunt now was not that anyway
Rma is a bummer especially this time of year
