[Screenshot from 2025-06-26 09-49-14] I am in QLD and our grids classed as A in the 2020 grid settings but pretty sure yours will work if dropped back to 2015 I just change 2015 settings to be within 2020 grid voltage range as 2015 is 265v and 2020 is 255v a password is needed https://gprivate…

Hi Dognose ID is 712134. At this point in time I am just trying to get my Victron to export any energy to the grid. Once I have ESS working to export to the grid that is a huge step forward. I have send a support request through to my power provider to ask if they have any restrictions on the time…

I’m not an expert on Grid-Codes, but I can see that you set a negative setpoint of -1812 today, which the system didn’t do. So, “something” inside your system configuration is telling the inverters to not feedin. I’m noting, that your VRM Portal is showing no value for “Grid” and also your system …

Thank you so much for taking a look into this. At the time you most likely looked into this I would have switched the inverter to inverter so no grid, to stabablise the PV to charge the batteries and supply the loads. In addition due to the dodgy way that Australia charges for grid usage for ON DE…

That is really a crazy pricing policy. Well, ofc, when you switch to inverter only, the system won’t feedin. But assume, you had it connected again when testing this. So, would need to check what the grid values were during your testing attempt. Eventually it was supposed to reconnect to the grid,…

@danwnz , I also have a grid connected MP2 victron setup, connected to Home assistant. I don’t use the integration at all, rather map all the ModbusTCP addresses via yaml. There is a full list of registers available on the victron professional portal which you can sign up to access. My HA does full…

@danwnz I’m in South Australia, and with Amber.

@gnsa14 do you have an installer you’d recommend in SA that’s competant with such systems? Thanks!

I did a lot of it myself. Regarding the Victron gear, try Generate Energy. Home Assistant you’ll need to do yourself, but there’s plenty of help online

I still haven’t got this working, and am still trying to find a solar installer in Brisbane to do whatever is required to join my system to the grid and be able to export battery power. I started down the path of modbus, and had that setup where it should have exported but it didn’t. I ended up co…
