Yes, a freezer with a controllable thermostat could be interesting to store energy in the form of cold.
When the photovoltaic product, the thermostat is set to -20 ° or -25 ° depending on the possibilities of the freezer and when it does not produce, the thermostat is set at -12 ° to ensure the preservation of food.
With a freezer well insulated (and not open), the rise time from -25 ° to -12 ° should allow to hold at least one night.
