Hello, I've modeled a photoltaic system with inverter and AC storage system on DesignBuilder, I'd like to visualize the charging cycle of the battery and the amount of electricity that my sysem is able to self-consume, but I can't find this on the summary report. Anyone knows if there's something to flag in the simulation output tab?

You will have to request the desired outputs via the scripting dialog.

ElectricLoadCenter:Storage:Battery or, ElectricLoadCenter:Storage:Simple

Regarding "amount of electricity that my system is able to self-consume", this information is presented in the ABUPS report, table electric loads satisfied.

I agree with Greg, if you have the Scripting License, that’s the easiest way. If not, you'll need to manually edit your IDF file and add the required outputs listed in the RDD file.

You can include any of the following outputs, either by selecting them through the Scripting interface (if available) or by copying them from the RDD file into your IDF (change Daily to whatever time resolution your simulation provides):

Output:Variable, *, Electric Storage Charge Energy, Daily;
Output:Variable, *, Electric Storage Charge Power, Daily;
Output:Variable, *, Electric Storage Discharge Energy, Daily;
Output:Variable, *, Electric Storage Discharge Power, Daily;
Output:Variable, *, Electric Storage Production Decrement Energy, Daily;
Output:Variable, *, Electric Storage Simple Charge State, Daily;
Output:Variable, *, Electric Storage Thermal Loss Energy, Daily;
Output:Variable, *, Electric Storage Thermal Loss Rate, Daily;

Detailed steps for both methods are available here:

Personally, I prefer using the Simulation Manager to set things up, and then view the results using the DesignBuilder Results Viewer (which is free).
