Stop Storing Electricity, Start Storing Cold: here is HOW my system works perfectly - 139

Can you run a -20°C freezer anywhere with just one solar panel and no massive battery bank? ????☀️
Don’t spend €500 on batteries when you can use physics. Let’s build smarter solar together.

In the previous video I explained the principles, now we build it. If you watch this, you will have one yourself before the first heat wave strikes. I explain also the solutions that proved to be wrong.

Still better for the DIY that is determined to have an independent micro ice factory: visit my link with PDF and video, both showing the fine details:

This video is part of the PV2COM playlist, which explores direct solar coupling to devices in order to produce and store essential commodities instead of just storing electricity.

Find the necessary components for two markets by using the links below. The cost to you is the same, but I earn a small commission to keep these experiments going.

1. Solar Panel (200W+ 24V)
Best for 12V systems as the MPPT transforms higher voltage even in low light/clouds.
IT: https://amzn.to/41rCXn6
COM: https://amzn.to/4stZTNp

Smaller, Renogy 100W panel, monocristaline ultra flexibile
IT: https://amzn.to/4cYkCTZ This is what I have (see picture above)
COM: https://amzn.to/4t5AZE0 These are even two, with an interesting price

Portable panel 100 Watt that you see on 12:25 ???? Product link (affiliate):

2. 50L Compressor Fridge
Real cooling (not Peltier). Efficient and rugged.
IT: https://amzn.to/3Q36Ebv (Kesser, I have it)
COM: https://amzn.to/4dBZbdf (Alpicool) / https://amzn.to/3QwOeQu (BougeRV)

3. Victron SmartSolar MPPT 75/15
The essential "brain." It converts high voltage/low current into the 12V high current needed for the fridge. I have this
IT: https://amzn.to/47QFjzp
COM: https://amzn.to/3OceHSU

4. Small LiFePO₄ Battery (8-10Ah)
More energy storage, but less raw power than a SuperCap. I have this.
IT: https://amzn.to/4sL7Y0i
COM: https://amzn.to/4882aqg

Small 9 Ah lead battery (I have this, too)
IT: https://amzn.to/4cVQ7Ou
COM: I don’t find it

For other countries please refer to AliExpress, which takes a bit longer but costs less and also also easier to find a specific product in your country.
- 12 V compressor fridge Alpicool in different sizes. Alpicool seems to be the same as my Kesser. It has the most happy users on AliExpress. Choose at https://s.click.aliexpress.com/e/_c4TAPdIB
- EPEVER 1206AN. Tracer MPPT 10A, up to 60V Solar Charger Controller: also many happy users. https://s.click.aliexpress.com/e/_c2zeQwXl
