Hi Drake Probably the biggest development in off grid solar refrigeration is the growing use of battery free solar direct drive (SDD) fridges and freezers. These are now in widespread use by the global immunization community for vaccine refrigeration and some ice pack freezing. It is believed there are over 10,000 already deployed with many more planned in the next few years.
There are 7 manufacturers around the globe that have earned WHO "pre-qualification" after passing stringent testing focused on conserving vaccine. Some also offer SDD for other uses. To see who they are go the WHO website and see their catalog with approved fridges and freezers at http://apps.who.int/immunization_standards/vaccine_quality/pqs_catalogue/ Best wishes Steve McCarney, Director of Cold Chain Solutions, Solar Electric Light Fund On Tue, Jun 27, 2017 at 9:25 AM, Drake <drake.chamber...@redwoodalliance.org > wrote: > Hello Wrenches, > > What is your preferred refrigerator for off grid installations?
