I'm assuming you added PV via the OpenStudio SketchUp Plugin user script, which generates a basic PV setup, inverter & electric load distribution.
I don't believe the OpenStudio Application supports PV editing. I also haven't found published measures that could support similar editing, or extend a basic PV setup to include Li-ion batteries. Hopefully someone more active in this area can prove me wrong. Otherwise, you're left with 3 options, IMO:
Adapt an SDK-based script (like this one), so it opens your model and adds/links the required PV-related objects (OpenStudio-resources tests are awesome demos).
Hack your generated .osm to add/edit the required PV-related objects described here. It's quicker than option #1, yet riskier (e.g. OS Object handles). It may take a few tries - hit & miss.
Similar to option #2: hack your generated .idf so it reflects PV-related additions/edits here. Fewer steps than #2, yet reverse translation (from IDF to OSM) would no longer be possible.
Option #1 is definitely safer, reusable. It does require an SDK-environment, and it's definitely a learning curve for beginners. But if you plan to do similar additions/edits in the future, it may be worth the time investment. You can take it a step further: develop a measure (with a few options) and share.
I just assign PV panels according to what you show in the picture in OpenStudio and then export IDF file and then add Battery to it in Energy Plus software.link text is it correct?
Were you able to run an EnergyPlus simulation? Any errors messages? I can't access the linked file - needs permission.
@sheida, I'm indeed able to access the IDF. However, it holds a number of invalid/missing entries that prevent E+ from running a simulation. These are unrelated to PV/batteries. I stopped bringing in incremental fixes as it gets rather messy with broken plant loop entries. I suggest you first make sure that your initial OpenStudio model can safely run an EnergyPlus simulation (without major errors), BEFORE adding PV/battery entries. And IMO you shouldn't have to rely on the IDF Editor to complete option #3 - a text editor and a few copy/paste steps should do the trick.

You're after something like Li-ion batteries + PV (idf example), right? Answers depend on the OpenStudio frontend (e.g. Application, SketchUp plugin user scripts, Ruby/Python SDK-based scripts). BEopt supports this directly, for instance. So for which frontend?
I modeled my building in sketch up and then use open studio to import data, I added PV panels in openstudio but it is on-grid PV, I need to add battery to PV and make it off-grid, I CAN share my file.
