Do you have a similar graph for the cfx355im with the icemaker on and in maintenance mode (after the initial power spike to make ice, and then the following maintenance power mode to keep the ice frozen in the trays) ?Over a lot of conversations, we've heard a lot of questions related to fridge use and energy consumption; in particular, how long can you run a fridge without ending up in a "no-start" situation.
There are a lot of factors involved in determining this: type of battery or batteries, condition of the charging system, wiring to the fridge, how often you open the fridge, actual electrical consumption that the fridge requires, etc. While we may not be able to determine the condition of your wiring or charging system, we can help with info on what the CFX3 line of fridges consumes power-wise.

In the above graph, we've measured each of our CFX3 models running at typical fridge (39 degrees F) and freezer temperatures (5 degrees F) and how external ambient temp impacts energy consumption. Given that the hottest temps will be in the day, you can rest assured that power consumption at night will be much lower regardless of what temp you set.
While the above graph will help you decide what CFX3 you might be interested in and how your power system will support, you'll also have access to our updated app. Not only does it help you control and monitoring everything on your cooler, it even tracks power consumption. You'll quickly get a feel of how it works with your battery, batteries, or a stand-alone power source like our PLB-40.

The Dometic website specs say the power usage should be 1.2 amps per hour at 4 degrees celsius internal fridge temperature, icemaker on (in maintenance mode) ambient temperature 32 degrees celsius.
However, our new cfx355im has power usage of 2-2.25 amps per hour at 4 degrees celsius internal fridge temperature, icemaker on in maintenance mode (fridge has been on and closed for 4 days so we assume it is in this mode), ambient temperature 24 degrees celsius.
It drained our plb40 from 100% to 10% in one period of 16 hours. Is this expected ? It is nearly double the published power usage at a much lower ambient temperature.
Also, how many hours after turning the icemaker on will it go into maintenance mode ?
