Hello, i want to design an off grid system inside an on grid system because my load will be just 6 electric cars and my system capacitat will be 35,5 kWp with a battery system so the question is i dont want to feed the extra power to the grid because the company is in a private grid and they cant feed the grid and I need just to get electricity from the grid when the pv system does not produce enough electricity and when the battery is empty too is it possible to do that on the software. pv project.pvprj
