    Where is this guy getting all these old laptop batteries?

    Very interesting work, only that the price of Tesla wall includes the inverter unit and energy management system with battery pack as a whole. Also, the unit that can charge the battery pack from the solar panel (a DC source) is a converter (DC-to-DC) not an inverter (DC-to-AC).

    "2 thousand miliamps" Yeah, 2 amps......

    You use 1Kohm resistor as fuse?? you loose some power on each cell because of that!

    Can you wire those batteries parallel withouth fear it will empty each others???

    Did he just say Lithium is "non-toxic" Man needs to buy a book.

    Well that is very interesting but in Spain we have our own way of life, you know.... Look, you want to put one of this in your house to save money. Ok, then you must pay to the company a tax support. Why? Well, you need the company to support your system when your battery are empty or your solar pannel doesn't work. Don't you? So you better pay the bill and forget it. You don't? Then could be fined. So it is cheaper to do anything. That it is. Spanish way of life.

    I am no expert here but don’t you need some special charging circuit, for lithium batteries, any old inverter would work?

    No need for BMS?

    you need to be a sparky to do this

    non toxic lol, yeah I bet.

    The solar array is producing DC...so why a double inversion to store the PV power? Or did I misunderstand? Isn't it more efficient to go PV DC to battery storage DC through a DC charge controller?And then charge the EV with DC with the same charge controller?

    Would be interesting if you measured the actual battery capacity now that it's built... Curious to know how much it varies from the predicted capacity. Without that bit of information it's hard to know whether your strategy of using recycled laptop batteries worked. Personally I'm guessing your 2000mAh rating for each cell is off by a factor of at least 2.
    Also, stating the obvious here, but any lithium-ion battery bank is going need some circuitry to prevent over charging and over discharging. I'm curious what you'll use that can handle the amount of current this bank can provide. Not saying it doesn't exist of course, but without that bit of circuitry this isn't a functional battery bank yet.
    And I'd seriously consider using hardie board or similar for the backing (the side that touches your house) in case of failure. It's a cheap and easy way to at least somewhat compensate for the fact that unlike the PowerWall this has no thermal protection.
    And all that said, keep up the great work, love your videos!

    You are fantastic, serious and on the topic!

    the batteries used in the power wall do not use lithium, because the lithium has a much lower useful life compared to the nickel, cobalt and aluminum battery
