PV System withou injection energy to grid

[Michalis Angeli]

I want to build a system in PVSYST that doesn't inject energy to grid. Which option should i select in ordrer to do this?

In my system, i will use battery system obviously, but the energy that saved in batteries will release only to my loads and nothing to grid.

You should design a “Stand-alone system” in this case.

Thank you about that, but by mistake i forgot to note that my system will be connected to grid, but wiil not exhange energy with gird. the excess energy will be saved in batteries.

Should i  design a different project??

If your system does not exchange energy with the grid, it means that the grid will only be there as a backup to cover for excess load, is that right?
What about times when the batteries are fully charged?

[Michalis Angeli]

Hello,
First of all, yes the grid will be there as a backup to cover excess load, only in cases that batteries coulnd't cover these loads.

When the batteries are fully charged, the excess energy will be lost. In no case that energy will not inject to gird.

In this case please go on with "Grid connected" and not "Standalone". In the storage strategy you have the option to allow or forbid the solar energy injection into the grid.

Okay, thank you!
