Charge phones and electrical devices from your Dulas Solar Direct Drive (SDD) refrigerator, with absolutely no impact on the vaccine storage performance of the refrigerator.
The Dulas Solar Socket allows to you to make the most of your vaccine refrigerator’s photovoltaic array by accessing energy not needed by the refrigerator. Our intelligent control system continuously varies the amount of energy available to the socket, at all times prioritising vaccine storage, but still giving up to 100W of useful power.
The Dulas Solar Socket is the first step towards solarising remote health centres: providing the power to charge phones and other electrical devices. Using a Solar Socket harvests a similar amount of energy as installing a 200Wp solar power system.
Built into the refrigerator and completely automatic in operation the control system automatically senses when excess energy is available and turns the Solar Socket on. Should the solar output drop, the Solar Socket is turned off to keep the refrigerator running.
