Battery doesn't charge as expected

[Ignacio]

Hello everyone,

 

I have a system with a hybrid inverter with its batteries, and a on-grid normal inverter. When I simmulate, battery doesn't charge at all, in the results I can see SOC stays around 15-20% all months. The problem is it sends a lot of energy to the grid which is what I am trying to avoid with the use of batteries. What can be the problem?

 

Thanks!

Hi Ignacio,

this is hard to tell without the project file. Is it possbile to send via private message in this forum?

Best regards,
Frederik

Hello, no problem. I attach the project here.Calle_LaDonzella20_modificado.pvprj

 

The solar panels connected to the non-hybrid inverter are facing east, so during the morning the non-hybrid inverter should deal with the consumptions and the hybrid inverter should charge the batteries, but we are still sending a lot to the grid.

Thank you a lot, and happy holidays!
