we would urgently need the R25 Certification for Austria Grid. Is there any Information when this is available for Quattro-II 48/5000/70-50-50 ?
Many thanks in advance!
I'm completely new to Victron-World and setup my first installation: Grid -> EM24 -> MP II (x3) on AC-IN, parallel the load. So a parallel installation of the MultiPlus II to the "grid" (no AC-Out is used).
Unfortunately it shows the pages a little bit strange: Grid is not available. The EM24 is configured as Grid meter. Instead the AC load shows the values of the EM 24. But the AC-Load should be: Grid + Inverter. But it looks like, that the control works fine (200W from Grid as minimum adjusted).
Is there a way to change this?
Thank you and best,
I´m running the following system: 3 x Multiplus II 48/5000, 1 x Cerbo, 3 x MPPT, 9 x Pylontech US 3000, EM 24 for measuring the grid. The system runs since about 7 months without any problems.
All units on the newest firmware, the cerbo runs on 2.84.
Since yesterday I´ve a problem: allthough the grid is here as all the time, the cerbo shows grid lost and doesn´t reconnect to the grid. I´ve started the system a few times without solving the problem.
My energy supplier has measured the grid and says everything is fine.
So I don´t understand this behaviour. The system tries about every 15 minutes to reconnect to the grid, then the relais in the Multiplus are switching and immediately comes the message: time synchronisation failed or one of the expected units were not found.
Anyone an idea why the Multis don´t switch trough to the grid?
I have a quattro + fronius microgrid that's not working very well (tried on output of quattro, tried on input... it's limiting the hell out of fronius output), so i'm currently using the fronius smart meter to limit injection to grid (undesirable as I pay for export).
But next week, I will install another 3Kw system with Huawei inverter (this will also be grid-tied and approved by the power co. for export).
Below is the diagram that I though on using. Basically just inserting the 3Kw Huawei inverter between the grid and the smart meter.
After this new installation, I can inject a bit more to grid from the fronius, or victron, as long as anti-islanding is obtained.
PS - my victron is acting up under heavy loads ( i need to warranty is someday...) from battery, so I am forced to user the EV charger directly form Grid or whenever I do have solar enough to discharge from battery less than 2-3kwh, hence the location.
I have a client who already has SMA tri10000 inverter and 7 kWp solar on site. He also have 10 kWh LTO battery and would like to connect with 3 of multi 3kVa inverter. We are in Australia and multi with battery is not allowed to connect to the grid. We are thinking to connecting SMA to multi and grid as back up. The idea is to install a relay on grid side, when battery is low , contactor close and use grid to supply load. When battery is above some value, use solar and battery to supply the load. All solar and battery energy will NOT be allowed to export to grid. and Grid will not charge battery. I am not sure whether we can achieve this as I did not find any info about 0 EXPORT from SMA - victron connection. Thanks
