Yes. If food is kept in a fridge or freezer to be sold to the general public then those fridges and freezers must always have electricity to maintain their correct temperature. It is not satisfactory to rely on their insulation. This applies to my clients business and is a condition of his licence to operate on the sites he trades at.
We tried electric-start Honda frame generators triggered to start by a separate thermostat inside the fridges and freezers but they did not start reliably and had to be exposed to the possibility of theft in order to run. The modifications to do this to the van were unacceptable we decided after doing one van.
When I did the analysis, it is more economic too because the generators consume less gas, break down less frequently and have a longer life. Two other benefits are the van is quieter more of the time and produces less CO2. The staff, mainly women, also like not having to start and stop and regularly checking the gennie.
As I finished with in one of my earlier posts I am not suggesting this is your solution but rather something similar and at a smaller scale. For example you said it only operates at the weekend whereas my solution is every hour, every day all year.
