20 thoughts on “Storing solar energy at home”

  1. Since when do you put voltage into a battery to charge it up. I have always put current into the battery until it gets to the correct voltage and then it stop the current flow. If you guys are using voltage to fill a battery you really are amazing hahaha. There is nothing new here and what you are saying is only fooling the public who don't know any better. Any engineer would tell you that.

  2. If the chip can change the voltage, it is somehow wing down and storing energy before it comes out. So, is there a way to engineer is so it slows down the energy coming out until the energy is needed in the household, and not use batteries?

  3. The silicon chip is called mosfet and is around in decades. Actually smps are used as battery chargers almost everywhere where high power batteries are involved today. Basically the charger control switches the power MOS transistors in very short pulses and it's resistance is very close to zero when on, hence providing the current that the battery needs to charge in pulses. Basically the time on and off of the transistor determines the regulated output energy. Said pulses get filtered and smoothed in order to provide a somewhat regular current. This means that the powers supply is efficient because there is very little loss in the transistor when on, due to the fact that it's fully on and the voltage drop across it is very low.
    Also lithium ion batteries needs to be charged at a constant current, not constant voltage. The voltage across the battery changes, as the charge builds up. The charger has to change the voltage in order to deliver the same current through the battery (at least to the point when the voltage is 4.2v a cell) and also measure it, in order to prevent overcharge because then funny (or not so funny) things happen otherwise.

  4. I had to stop half way through due to the bull shit overload. I never expected such a video of such a renowned semiconductor manufacturer. The thinly veiled excuse to produce the video and let's of course make sure we get a pretty blonde in it so that we keep watching but not for me thank you. It is not solar technology that is driving higher efficiency semiconductors. The drive for higher efficiency semiconductors or rather semiconductors with an ever lower resistance is driven by every area of technology as the resistance of semiconductors produces heat and this limits their application in high-power solutions.

  5. As far as Solar Energy is considered, there are number of countries, and number of companies have come out their own way. What is important is the device, the one which acts as an interface, between the Energy that flows and the Storage- the Battery. I would like to know in what way the Infineon,s R&D, has developed a new, or better equipment, which will be more efficient, and reliable, without costing much comparatively

  6. Store the PV energy in hot water for showers and washing machines including dish washer. I can use 4-6 kw a day doing this with only £400 cost using a diverter. If you home is low energy it help with heating in spring and autumn. Water is cheap storage. I think its a good video as it explains the idea well and if people want it its up to them just like a new car or kitchen. Here in UK electric cars loose 80% of their new cost in 3 years makes solar look good. Buy a electric car second hand get free batteries and a car. Use the car for battery storage, it will happen.

  7. But Consider a situation like this house electrical equipment started to work from Battery and if suddenly all equipment was on and currents shoots Up what will Happen
    Sorry for Bad English

  8. Remember this was done 5 years ago and that may be when mppt was started but mppt chargers need to come down in price

  9. solar energy stored in batteries is inviable. The lifetime of batteries is too small and they are very expensive. No possible

  10. I am all for solar however what happens when there is rainy weather? There will still be the demand on the grid, so this technology will work great when there is plenty of sun, but when there is heavy cloud cover the grid will still need to supply power for everyone.

  11. there is no difference between this and any other solar controller/charger ….I don't get it….plus lithium batteries are crazy expensive why bother when you can get MORE storage for so much less money and they last about 10 years….

  12. This new kind of technology will be really great help since summer is near.. we can harness solar power as much as we want..
