Hi , 

In the attached picture , How I can use PV*SOL to planning my project ?

Thank you in advance

Hello mmakatri,

on the page "System, Climate and Grid", choose the System Type "Grid-Connected PV System with Electrical Appliances and Battery Systems".

Then you can select battery systems on the Battery Systems page. There are three types of systems, as described here:

Yours would be a "DC intermediate" or "DC-link" coupling.

Hope that helps, kind regards,

Martin

Thank you developer_mh

but what about the converter from DC to AC shown in the picture bellow ?

 

Dear mmakatri,

I am not sure if I understand your question correctly. What do you mean by "what about the converter"?

Kind regards,

Martin

Dear developer_mh

Thank for your answer, In my system I do not have DC/AC inverter connected to the grid because we do not have a grid , So how I can use this system type, The system will take in consideration the DC/AC inverter (Wiring , Cost, drop etc)

 

Thank you in advance

Dear developer_mh, 

 

Our system is more like this image but I did not find this type in the PVSOL

Dear mmakatri,

if you don't have a grid, i.e. a "stand-alone" (or "offgrid") system, the only two system types that you can use are the last two from the list:

 

For stand-alone systems, we don't have DC/DC coupled battery systems at the moment, I am afraid. But you can do the following to approximate your system:

• Set the grid voltage to your DC bus voltage (12 V or 24 V, or whatever you use in your system)
• Also set the mains voltage of the PV and the battery inverter to the same voltage
• modify the DC/AC efficiency of the PV inverter and the AC/DC efficiency of the battery inverter so that the "PV to battery" , the "battery to load" and the PV to load" energy paths are met as precisely as possible
• On the cabling page, just set the cable lengths of the AC side as your DC bus cables

The results will be very close to a real DC coupled offgrid battery-PV system.

Hope that helps, kind regards,

Martin
