I am proposing to use a Victron 12/800 inverter to power my 240V fridge in my RV. Since a fridge typically runs intermittently (on for 20 minutes, off for an hour or two) it seems logical to NOT be wasting the energy involved in the standby current for an inverter. So it seems to make sense that when the fridge “shuts down” the inverter should also shut down and just keep checking every minute or two to see if the fridge wants to run again.
My local Vistron agent says they have not heard of this configuration before and could not give me any guidance as to whether it would work or not.
Can anyone else help please?
The fridge draws 375W when running. It is a modern inverter fridge.
However, there are two things that might go wrong:
The freezer would need to start drawing power fast enough to keep the multi awake, when it’s currently “searching”.
The freezer may just “restart” it’s internal counter (if not exclusively temperature regulated), when loosing power and basically be restored 2 seconds later. So, may end up in an infinite loop of running 20 minutes, off 2 seconds, running 20 minutes…
Thanks for that. I would expect the fridge to be solely triggered by the internal temperature. So once there temp climbs above the trigger point then the next time the inverter gives it some power it should start the compressor to cool down again. Your point #1 about the fridge starting up fast enough before the inverter goes to sleep again it’s something I will have to investigate.
Thanks again
Yeah that looks similar to the victron. Have you used it in eco mode?
Viewed in Victron Connect. I did try ECO mode when I first got the inverter and it worked as I expected, but since then I have not had a need for it (circumstances changed).
