Total feed-in battery instalation

[Henrique Teixeira]

Hello,

I have two questions regarding some projects with the propose to full feed-in the energy to the grid.

I update today the PVSOL for de 2025 R3 version and this type of simulation has changed.

For exemple, I made a 2D simulation for 12 MW tracking and 4 MWh of battery. It usually charges de battery only from de PV when it starts do generate power and after the battery becames full, it feed-in the energy to the grid. The only shedule that I made is for discharging between 0:00 and 04:00 o'clock. I do not ativate charging periods.

With this update, sometimes to charge the battery it consumes from grid (charging from grid). I do not want that, How can I limit that?

Other question. It is possible to enable charging only after the PV Power became above the clipping power?

Hi Henrique,

could you provide a project file please? You can send it to hotline@valentin-software.com or send it here by private message.

Thanks and kind regards,

Martin

Dear Henrique,

Thank you for your inquiry.

We cannot reproduce your problem. In the Energy Flow Graph we can see that the battery is not charged from the grid.

Regarding your second question: Unfortunately, it isn't possible to enable charging only after the PV Power became above the clipping power.
