We are often asked whether our 12 volt fridges can be run off the mains power while you're on a campsite hook-up. The short answer is no, not on their own...
However, add an MPS box, and that is exactly what happens. Simply connect your 12volt supply and your 240v volt supply to the MPS unit - then plug your fridge into it. The MPS will automatically switch to using mains power to run your fridge whenever it's available.
Why would you want to do this? Mainly because it allows your leisure battery to charge fully while you are hooked up to the mains, (without the fridge pinching power at the same time!). It allows your mains charger to operate as effectively as possible. Modern chargers go through several stages while charging up your battery but, if you are drawing power out at the same time as charging, that functionality is less effective.
One other benefit of the MPS unit is that, in order to preserve battery power, you might choose to run your fridge 'colder' while on a mains supply - and then raise the thermostat setting when you are off-grid to use less power.
