Wondering if FMPS (class 4) will be able to make a 48V+ battery system safe to touch. That would make for example a 380V battery still a DIY possible. However, I don't understand why you say that a 48V is DIY while you still have to mess with HV-DC solar panels and HV-AC main panel. Isn't the...

Part I As now FMPS (Class 4) has been included in NEC it seems that HV-DC becomes more realistic scenario for homes. I'm wondering if anyone had so far any experience with solar systems and FMPS and if you think it could be done to increase efficiency and safety. My purpose is to build an HV-DC...

Yes, but generally the more conversations (I think that DC->DC can be more efficient though) that you will perform the more power you lose. I was looking into HVDC and Class 4, so might be better to run 100-380v (batteries) DC in to your house with safety and converters at the end to avoid cable...

That's really interesting, I had to find time and check more details as I had no idea about passive houses. I will definitely look more in to it. Thanks!

Well said, however companies should adapt to our needs with normal prices too. If they don't do it, we should not give them money for products that are not even doing what we want to do. For example giving the same product without the AC converter and make it more expensive it doesn't make sense...

As a beginner and soon an owner of a house, I've spend last week watching Will's videos and generally reading about DIY solar power and electronics. Even my field (IT) is within the technology I didn't know a lot of things about electronics (and still don't). The main part I was missing is the...
