- In a one week test in mid-winter, freezer consumed 330 watt-hours/day. Freezer is at approx. 0F (C) and ambient temperature 55F (13C). The old upright freezer used 1450 watt-hours/day in similar conditions or 4.4 times as much energy!
Freezer is made in the USA by:
Solar Freeze, Llc

It seems that the compressor is made by Secop (formerly Danfoss) and is packaged by Keota for use in the Solar Freeze Sunstar freezers.
It is as "no frills" as you can get, manual defrost, no digital display, no WiFi, just a plain old thermostat dial and a power and fault LED indicator.
Ordered from:

They seemed to have the best price including shipping. They are located in Canada, so you may get hit with a currency conversion fee when ordering, but there was no sales tax added.
This project has taken over a year to complete, so videos have been shot at various times over that period.
More to come...

And as always, thanks for watching - แนวปฏิบัติและการใช้ชีวิต
Over the last year, energy consumption has ranged from a low of 290WH/day in mid-winter up to 516WH/day in mid-summer. I've left the freezer on the lowest speed setting the whole time and it's been running directly off the 24V solar battery bank the whole time. The freezer is located in an unconditioned garage.
Running some tests now to drop the energy consumption even farther, stay tuned for those results.
Interesting stuff, thank you! Those energy savings are just going to add up and up over time. Must be a good feeling 👍
Just read your video description - I hadn’t realised it was a Danfoss compressor. Maybe the BD35 or BD50? I had discovered that unit when I was considering doing a DC conversion on my old fridge and freezer, but gave up the idea when I realised the plumbing involved in getting a gas tight seal on the refrigerant circuit would be beyond me. They’re great compressors and can sometimes be bought cheaply as part of used boat fridges/freezers in classified listings.
Yes, this one is a re-badged BD35. Like you, I'm finding those things used all over the place. I've heard that some of the marine versions have some neat refrigerant line fittings that allow for connection and disconnection without leaks. But you would need to have mating connections on your old appliance. Probably need to find an AC tech to connect up, evacuate and fill the system otherwise. There are some videos on YT showing those conversions.
Hello friend. I need to buy one of these freezers... I do not know where to buy.... where did you buy yours? Thanks.
You can find that information is in the video description.
