    Dear Andrea Rossi,

    For the Basic Controller and three SKLep units, may I reasonably assume:

    1. There is a single cable going from each SKLep to the Controller?
    2. On the SKLep, there is a single connector for the input power?
    3. There is another connector on the SKLep for the output power?

  • Andrea Rossi

    Steven Nicholes Karels:
    It is ready,
    Warm Regards,

    Dear Andrea Rossi,

    Everyone asks about the SKLep. How is the Controller (for the SKLep) development going?

    Dear Andrea Rossi,

    I have built a third Prototype test unit. So, I am ready to receive the SKLep units when they finally arrive.

    Each Prototype unit accepts AC power and that power is distributed to three 12 – 15 VDC power supplies whose outputs are wired in series. That DC output (36VDC to 45VDC) is provided to an Enphase micro-inverter. The micro-inverter is also connected to grid power (nominally 240 VAC, 60 Hz).

    Prototypes 1 & 2 each use one Enphase IQ7A micro-inverter. Prototype 3 uses an Enphase IQ8A micro-inverter (the next generation micro-inverter from Enphase).

    A test was conducted on 19 May 2022 of the Prototypes for electrical generation. The input AC power was not measured and is separate from the measured Grid power circuit. The Grid power (240 VAC) was connected to each of the three prototypes and was measured.

    Test 1 – all Prototypes connected to the Grid but they are powered off. Result was approximately 2W of power consumption in total by the three micro-inverters. This is in agreement with their specifications.

    Test 2 – One unit s power ON, the other two units powered OFF, all connected to Grid power.

    Prototype 1: 363.4W
    Prototype 2: 367.0W
    Prototype 3: 355.8W

    Test 3 – Two Prototypes ON, One Prototype OFF, all connected to the Grid.

    Prototypes 1 & 2: 733.6W
    Prototypes 1 & 3: 725.9W
    Prototypes 2 & 3: 722.5W

    Test 4 – All Prototypes ON, All connected to the Grid.

    All Prototypes ON: 1,092.1W

    Conclusions: Good agreement between units. The Enphase IQ8A appears to produce about 12W less output power than the IQ7A units, although still within specifications.

    Plot Results: Plotting showed good agreement with a linear fit of:

    y = 364.82 * x – 2.425; where y is the generated grid power and x is the number of prototype units powered ON. R2 was 0.9998.

    REMEMBER: These test Prototype units did not have SKLep units. Conventional power supplies, powered from another circuit, are simulating the output of the SKLep units.

    Dr. Rossi,
    If you can say, roughly what % of your time are you able to spend:

    R) Research– e.g., working on potential new devices, like the 1kW SKLep?

    D) Development– e.g., productizing soon-to-be-released products like the 100W SKLep?

    S) Sales– e.g., working with potential new customers?

    T) Tennis– e.g., upping your tennis game with your wife?

    I hope you’re having significant time for both R & T!

  • Wilfried Babelotzky

    Dear Andrea,

    do you already know if the 1kW SKLep will be smaller in volume (in litres) than 10 SKLep 100W, how much smaller at least?

    Best regards
    Wilfried

  • Wilfried Babelotzky

    Dear Andrea,

    did you choose the DC-DC standard 12V from an internal or external point of view on the SKLep?
    Could the SKLep technically, in terms of internal components to be adapted, also be operated with external 5V-5V?

    Best regards
    Wilfried

  • Steven Nicholes Karels

    Udo,

    I am building prototype test systems to be ready for when the SKLep units are delivered to me. My prototypes use, in place of the SKLep units, three 120VAC input, 12VDC output, 105W power supplies, wired in series, to produce 36VDC, 300W power. This DC power feeds the Enphase micro-inverter which generates 240VAC power. The prototype design is to validate all input and output circuitry so when I received the actual SKLeps, I know that the rest of the circuitry is properly functioning.

    My design uses Enphase micro-inverters (identical to those used with solar panels) for an on-grid system. I plan on using 5 to 10 of these units to power my home.

    Hello,
    very interesting, thanks for doing the tests.

    I would like to test the micro-inverter EVT560 from Envertech (www.envertech.com) but the inverter is currently not available in Germany. If it works, the EVT560 can serve 6 Ecats (2×3) and has an output of 560W continious. Up to 10 VT560 can be attached to a single branch connected to the grid. There are other inverters available from Envertech but I think they would overload the Ecats.

    I also contacted Envertech support and asked if their inverters would work with Ecats. I gave them the Ecat data and got the answer that it could work but needs to be tested first. I think that is the best answer I could get right now.

    I think one of the biggest problems with connecting Ecats to a micro-inverter is the possibility of overloading the Ecats. As Andrea Rossi has already confirmed, the Ecat does not lower the voltage (or power) when overloaded, it just shuts down. If the Ecat were to reduce power, that would work with many inverters with MPPT (maximum power point tracking).
    Maybe if the Ecat recovers quickly enough from a shutdown, or if the output voltage of the Ecats can be set to the maximum of the inverter’s MPPT range (EVT560 = 45V = 3 Ecats at 15V), it might work. I don’t know, this needs to be tested. Maybe we need to invent a power limiter for Ecats.

    One question: what happens if you connect a load of 1 or 2 kW, for example a heater. How much power is drawn from the grid and how much from the Enphase IQ7A micro inverter?

    Thank you very much and best regards
    Dieter

    Dear Andrea Rossi,

    Is the standard SKLep unit a DC input/DC output only, with additional components available for AC input and/or AC Output? Such as AC to DC wall adapters or power supplies and a DC to AC inverter separate from the standard SKLep unit?

    Dear Andrea,
    your answer to Andreas and Enzo is very exhaustive and clear, but please also take into account possible data leaks or data stolen fraudulently, this could change the scenario dramatically.
    Regards, Giuseppe

  • Yuri

    Dr Rossi,
    Your answers to Andreas and Enzo Amato are honest and convincing. I would underline also the fact that you did not get any money from all the persons that made pre-orders, and you wrote clearly in the pre-orders forms that the deliveries are contingent with the collection of orders for at least 1 million units: this gives clear evidence of your honesty.
    By the way, I am sure you have a plan B to launch your technology.
    All the best,
    Yuri

  • Chris Beall

    Dr. Rossi,

    On ecat.com you offer pre-orders of 4 different variations of Ecat SKLep:
    DC in, DC out
    DC in, AC out
    AC in, DC out
    AC in, AC out

    Can you share with us, in percentage terms, how those 4 variations are distributed among the pre-orders received so far? (I already lost one pre-order when the SKLed turned out to not be as popular as required, so now I’m a bit nervous about the alternative I selected.)

    Regards,
    Chris Beall

  • WaltC

    Dr. Rossi,
    For large buyers, it makes a huge difference to their business models as to whether the Ecat-SKLep has an actual average lifespan of months, or 3 years (the current Warranty Period), or 100K hours (the current rated service life), or possibly even longer. I imagine that large buyers must want tangible evidence in regard to lifespan.

    Also, similar to the times when Auto manufacturers have had to recall hundreds of thousands of automobiles (like when one make of airbag required replacement), I’d imagine that large buyers would want some level of confidence that Leonardo could afford to make good on that.

    Questions:
    1) Are you able to provide evidence to large buyers that the 3 year warranty and the 100K hours of service life have a strong factual basis?
    2) If so, can you share any of that with us?
    3) Also, if in the event that there were an unexpected, high-failure-rate problem with the Ecat-SKLep device, or one of the subcomponents (chips, potentiometers, connectors, etc.) are you able to convince large buyers that Leonardo has sufficient funding to be able to manage the Warranty replacements?
    4) If so, anything you can share?

    Best wishes,
    WaltC

    Dear Andrea,

    People always try to tell us that we have a good life thanks to investors.
    I think that investment in our society is sometimes a dirty and underhanded game in which physical, biological and intangible values ​​are taken into account too little or too late.
    For example: The cleanup after the Three Mile Island reactor accident cost about two billion in current dollars and took 15 years.

    Currently in my country Belgium, the head of the Public Prosecutor and the police forces come to our parliament to declare that they are no longer able to cope with the resources and the clout of organized crime.
    That’s what happens when you take the market as a guideline and don’t let moral priorities dominate over money.
    I think that at the global level we now need the level of US military resources to reduce organized crime.
    We don’t even have the resources on a global level to reverse the moral and biological decay.

    All those who sell oil, gas, nuclear energy and so-called renewable energy will remain your enemies. This until they die. What else should they do? They simply belong to the established power. Everyone depends on them.
    The ECat will not defeat them until it spreads spontaneously everywhere like an elusive virus.
    Given the current evolution and problems, I even wonder if there is a real business model possible with this technology, given its hostility towards the established powers.
    Indeed, the market will soon reverse engineer the technology. Every great invention from the past that everyone still uses today is a legacy of humanity. There is great value in educating the next generations about the technology needed to sustain the world. We also do not want the next generations to pay us because we would teach them?

    If I see the result of all your misery you’ve already had with investors: it’s always the big ones who want to invest “their” resources in your invention, who then call your invention theirs, or come to play the trojan horse.
    Their money was originally all created out of thin air from the central banks. Your invention is real matter that has real value.

    You can ignore all this. We will wait together a little much longer.

    Ardent Regards,
    Koen
