    A 5 kWh battery is about 1300 EUR, with a 10 year warranty.

    1-2 EUR is minimum saved pr. day. Let’s just say I only save 1 EUR pr. day. That’s 365 EUR/year. RoI is max 3.5 years.

      Oh I didn’t realize such small capacity batteries were worth the installation effort in a home. Does that 1300 include the inverter and battery management system? What about the installation of the interconnect?

      (I rent so I don’t know much about this stuff, thank you for your time!)
