So we got grid connected and trying to AC couple / Export to Grid trying with 1x test unit first before doing all the parallel units tried for a few days now as soon as ESS is installed through ve config the Grid tied inverters that were working AC coupled with the PV inverter assistant installed …

Hi could this be the problem: [image] Inverter Clicking every 4 minutes, output drops briefly, then rapid relay clicks DIY Hi everyone, I’ve just received a new Multiplus 2-GX and have encountered an issue during testing. I connected a battery, applied 240Vac to the inpu…

yeh they do that as well and its every 60 sec for me also found out these do not work on AS/NZS 4777.2:2020 settings but would work if they were on AS/NZS 4777.2:2015 settings the grid password is apparently ■■■■■■■■■■■■ ? when I was on the windows laptop I could not find it got back to my Lin…

looks like its still doing it it willl pass through the grid , ac couple with the PV inverter then it will decide to top up battery then go inverter disconnect grid then does 53hz and kill the PV inverter instead of passing through the grid i am trying to configure it to only top up battery to 48V…

and then if i bump up the sustain voltage to 52v it just keeps charging from the grid however on the AC coupled PV inverter it is saying its generating 70w but victron not showing any data ? (I thought it was in grid fault mode again ) pretty much as far as I know the earths are connected t…

then I disable the battery charger and it still tries to charge from grid wtf ? all I want is excess solar to export to grid , why is it always trying to charge battery and when battery full then dissconnect PV inverter ? [Screenshot from 2025-06-18 11-09-24] disablecharger.VenusOS_b827ebec…

also noticed something else only the OLD GUI is showing PV Inverter production

and put in inverter only mode it still keeps trying to charge batteries .. and kills grid connection so no way to export .. ffs [Screenshot from 2025-06-18 13-00-39]

am I mean to have DC export on ? [Screenshot from 2025-06-18 14-46-51]

and I did just find this Configure Grid Feed-in: Set it to “No” or “DC Coupled Grid Feed-in No”: This setting will prevent the system from charging the batteries using solar power when they are already full or when a specific SoC (State of Charge) is reached. Alternatively, set a high negative …

so now that its the end of the day i got it exporting again using a option it said not to use with ESS ? prooritizeothernergysources.VenusOS_b827ebec168c_inst_ttyUSB0_Interfaces_Mk2_Tunnel (Copy).rvsc (6.3 KB) but its pretty much back to the same settings as last time when battery voltage creeps u…
