Results not displaying correctly with TIME CONTROL activated
When I activate daily time control, it doesn't show up in the results. See the screenshot of the results: grid input remains 0 kWh.

If this is not correct. Can this be solved in a new software release of PVsol.

Please let me know,

Dear PV Pro,

Thank you for your inquiry.

The battery discharge to the grid is shown as 0 because this is a DC-coupled battery system. In these systems, PV energy and battery energy are simulated together and not output separately.

You can see in the diagram editor that battery discharge to the grid is still occurring – according to the time-controlled discharge function. On a day with high irradiation in March, the battery is fully charged at midday. Starting at 12:00 PM, grid feed-in occurs, which continuously decreases until 5:00 PM – as the PV energy decreases. From 5:00 PM onwards, grid feed-in increases again, as the battery is now being discharged to the grid. At 9:00 PM, grid feed-in/battery discharge is complete.

Thank you for your comment!

I already suspected this was related. So that's important to pay attention to.

And if I want to see how much electricity a DC-coupled system feeds back per year, I need to create a version with time control enabled and one with time control disabled. Then, under the inverter tab, under export to the grid, I can see how much more I feed back with the function enabled. then I know how much extra I feed back through this time-based discharge function. is this right?

 

But when the customer has an Dynamic energy contract this (above) is not accurate. This dynamic and seasonal/monthly addition would be an nice feature to implement for al PVsol users. That would make this software more attractive. That the battery will discharge during a few months when the price is above....ct. With maybe a few conditions that are used in battery inverters or EMS. For charging the same: if the price is below ...ct (during night or middle of the day) the battery can be filled. Also add a few conditions here that are used in battery inverters or EMS. You cab use NordPool or EPEX energy prices as guideline.

Yes, that's possible.

Another option would be to copy the battery system, change the coupling type, and run the simulation with an AC-coupled battery system.
