question about storage systems

[Nikoloz]

Hello I have such question . we have project with  huawei SUN2000-12K-MAP0 inverter  and huawei 7 kw elements, this inverter can work wth 2 powrmodules 21kw each it means 2 racks with 3 elements each. but i cannot add rackswith such amount of elements it deafolt has 1 rach with 8 elements ... how to change it?

The "number of elements" displayed might be misleading, as it should represent the total number of cells in your system, but it does not seem to take into account the number of blocks (or modules).

This is definitively a bug, but as long as the total voltage and capacity are consistent with your design, the computation will be valid.

So it means that I cannt change amount of batteries as i whish. i have o tell to my customer thas don't warry this project is with bugs ?

I think you misunderstood what I meant. You can any number of cells, modules and racks and it will be taken into account during the simulation.

Only this specific figure displayed here is false. But that's only for display, so it won't impact your simulation.

[Nikoloz]

Actually it counts in simulation. 20 batteries.

Again, if you change any figure for the battery, it WILL impact your simulation. If you change the number of cells or the number of blocks or the number of racks, the battery characteristics will be impacted (voltage for the components in series, capacity for the components in parallel).

The only issue I can see is the display of the number of UNITS in the grid storage window, which is not changed as it should when you change the number of blocks in the battery component.

Now, if you have this values in your report (10*2 Units) but did not set 10 racks in series and 2 racks in parallel, please contact us at support@pvsyst.com with your project so we can have a better look at what's happening.
