Consultation for photovoltaic systems

: Great, looks good. Nothing stands in the way of your own DIY storage!

Thanks, but I have to read and learn a lot again for that. It would of course be good if I could use the battery from the motorhome for the house. The battery must remain permanently in the motorhome because we like to start spontaneously. Do you already have any initial tips for me?

Uh, I haven't looked into it yet. At the moment I'm under so much stress that I am really enthusiastic about all that stuff, but simply don't have the time to really dive into it. And buying ready-made is not an option, as it doesn't make financial sense for me. I'll wait and see what the tax office says, if anything remains, then panels will go on the roof. Then step by step … Your system is already quite large, so a bigger storage would make sense.

At the current electricity price, the storage system may cost about €300/kW if it is to be operated economically. At least for the average household. Although with self-construction, you can even add a bit more, since you are then able to replace only individual parts yourself in case of defects. Commercial systems usually get broken by something like that.

I know I always sound like I am against storage systems. But actually, I can hardly wait to have one myself... Still, I try to hold back as long as I am sure that it pays off.

My 8 cells and the 2 BMS I bought directly from the Chinese manufacturer in spring 21. I think it was less than 1000 euros including accessories.

How much is that in €/kWh?

Understandable, if the heat pump doesn't pay off, then at least the storage should get everything back … :D Storage will only pay off if you do it yourself.
