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.

Ha, I know you’re an authentic Dane by how you spelled Denmark! I live in Estonia, slightly colder, but not the coldest. I haven’t yet gotten around to installing an air-to-water or ground source pump yet, so mine only heats the home, not the water (meaning I spend a whole lot of electricity on my regular boiler year round). It’s been running 24/7 since October currently, more or less. I could just go heat my furnace right now and turn off the pump, but that’s extra work + firewood costs money too. Long term goal is to replace the furnace completely, with a ground-source heat pump with vertical collectors since my garden isn’t big enough for horizontal.

Definitely same here, but I have a fixed price package and in the winter, the lows barely ever get to the level I pay year-round. This makes more sense for me since I use much less electricity (barely any) in the summer compared to the winter.
However, as I said previously, I discovered that it’s now possible to keep the fixed price for my electricity purchasing. If I got a couple of panels, they’d more than cover my electricity use in the summer and I wouldn’t have to worry about the price - and in the winter, I’d still be paying less than everyone on a variable rate plan like I do now. If I could also install some small turbines on the roof, that could actually halve my power bills in the winter too.
Only trouble is, I bought cheap roofing materials knowing I won’t have any use for solar panels anytime soon, and it won’t support the weight lol. Oh well. I saved like a thousand or two thousand euros compared to more expensive roofing materials at least.
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!)

Saving 1-2 EUR per day with a 6000+ EUR battery pack sounds…not worth it.
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.

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.
