If I pay 80€ for it, then I can calculate how many photovoltaic electricity wash cycles this thing would have to provide me with just to cover the purchase costs alone.
Apart from that, I also don’t like this principle of “device constantly turning on and off” when it’s cloudy (?). I can imagine it would be better for the laundry if the program runs regularly, without many interruptions.
Yes, that is totally off and shows how not to do it. When the machine is running, the cycle must also run through. 80€ for a basically "normal" switchable socket is totally exaggerated... among other things, that’s why such things are rejected by the broad masses, because the entry cost is excessive.
That’s why I write there must be a concept for the entire building and not something where you need "special" sockets.
In my case, load distribution costs me about 10€ per socket and a few minutes at the laptop. The sensors, etc. are already there for other subsystems anyway and you can use the data they provide for all applications and not just for a very specific one.
Energy management may be somewhat more efficient, but until you've recouped the necessary initial investments, a large family would probably have to wash for decades
As a rule, some kind of EMS is always necessary with photovoltaics. Ergo, you always have the expenses. So why not also get the last bit out of the system?
Do you have some keywords I can search for?
Hmm, do you want to know the names of the interfaces and protocols now? Like RS232, RS485, JTAG, etc. These are generally known, but handling them often requires training in this field.
Nope. But all have the problem of loading and unloading the washing machine, which must be done manually.
No, that’s not a problem but a necessity whether you have an EMS or not.
Sure, if someone enjoys something like that and sees it as a system made of many individual parts,
That’s the point. It’s not a solitary object, but part of a whole.
you first have to recoup the acquisition costs
Misconception. When building a house (and also other things in life), there are some things where you simply have to spend the money and never earn it back. In the case of photovoltaics, the fact is that some kind of energy management is always and necessarily required, so why not exploit the full potential?
In other words, the money is gone no matter what you do, because... well, because this black box must exist and without photovoltaics it provides no electricity from the roof. So it’s obvious that I want to get the highest degree of utility out of this black box. But yes, of course, there are also those who don’t care about that.
True, that’s why we don’t have one.
To each their own. Others do not want to live without it anymore. You have the same picture with the topic of the thread. Some don’t understand it and want to hear nothing about it, others find it pointless, third consider it uneconomical, and then of course there are those who get it all and see their benefit in it.
