  • I already had the inverter and solar panels for a few years, when I added the battery pack.

    BMS: 300 EUR Battery (5 kWh): 1300 EUR

    I can then stack batteries on top of each other op to 5 batteries in total.

    If you were to get the same setup, excluding solar panels, the price would be 3200 EUR.

    I’m sure that could be done a lot cheaper though, if you only wanted a battery pack and no solar. Then you could probably get a much cheaper inverter.

    I have 2000 kWp solar setup, which roughly saves me about 300 EUR/year.



  • Where do you live? I also have a heat pump for hot water and floor heating. Compared to winter, it barely runs in the summer months, but sounds like you live in a colder place than Danmark?

    There’s still money to be made (saved), by buying during the cheapest hours and using it during the expensive hours.

    I can save about 1-2 EUR every day by buying during cheap hours and using it during expensive hours. Days I can just use the sun, I of course save even more, because I barely have to buy any electricity, except for a few hours at night.
