EcoFlow and fridge question.

[Dannyb6467]

Morning folks.
I have an EcoFlow Delta Max 2 running an Igloo compressor fridge. Question is....what would deplete the battery quickest... running the fridge from the 240v or 12v outlets ?
Thanks.

i find that the fridges run better on the 240v side.

the maths would imply different. . . but I've tried it and it works better for me on 240v.

compressor load is around 60w while running down to temp,

then cycles on/off as needed . . . so its tricky to work out a real Wh number.

I've had a Delta2 max run two fridges for a weekend no problem.


++++++++++++


i think the real reason is that the EF 12v output is regulated at 12.0v

but the fridge PSU runs at 14.4v or similar.

so the compressor like the higher voltage, . . . with a fix 12.0v the fridge pulls more current to get the same Watts,

then you have 12v power volt drop over the connecting cable,

then the 12v plug and socket heating up.

all these minor point add up to the fridge running better off 240v from your EF D2M


++++++++++++

I'd agree. I ran it off 12v but to be honest and for the simplest of reasons, the cable is less intrusive running from the 240v sockets...I'll stay with the 240v. I'm finding it runs the fridge for 4 days but with the alternator charger it makes no difference to me. Thanks for the reply

Lee,
Does your EFDM2 keep losing WiFi connection? Basically mine is constantly disconnected from the app and I have to delete it and start again...no easy way to do it... The charge is always connected???

Hi Guys, I'm thinking of purchasing the Ecoflow Delta 2 Max rather than installing a leisure battery etc.

The fridge i've been looking at is a Camper Cool 12v fridge range is 1.5 amps. It will draw more when the compressor is working to cool the fridge down and less when the fridge is at the set temperature.

With your experience would this be adequate running my fridge for 2/3 days?, The van is insulated to a degree and is relatively cool.

Apologies, if my maths are wrong but i was thinking if it ran say at 2amps on average x 12V = 24amps x 72hrs - 1728amps for the duration of 72 hours.
The Ecoflow max has 2048wh capacity, so i'm guessing this would be okay?. It's highly likely i would be on EHU in most cases so wouldn't really matter i'd just keep the Ecoflow plugged into the EHU..

The other System i was looking at was the Bluetti AC240, it has the 30amp output socket i could run into a distribution board, powering not only the fridge but lights etc.

I hope this makes sense,

Many thanks Andy.

I run an igloo ICF 32, I'm not sure of it's power draw but with general use my Delta Max2 runs it for 4 or 5 days. I use the Ecoflow alternator charger that I just top up the battery by running the engine if I don't have mains. It's a perfect combo for me. As I say, before the charger it was around 5 days.

Many thanks Danny, much appreciated. The Ecoflow unit looks like a good option, in honesty i was thinking of the leisure battery but the Eco Flow whilst more expensive it a lot less hassle. I guess when you take all the add ons for 240V and 12V / solar etc the costs are probably not far off each other.

Mine is a lease van that I normally end up buying but you never know. This way is the least intrusive.

heres some quick maths:

++++++++++++++++

the EF D2Max is 2048Wh

the fridge is 12v@2A (W=VxA), so 12v*2A=24W or 24w per hour or 24wh


then devide the battery Wh by the load Wh to get the run time.


2048Wh/24Wh = 85hrs or 85hr/24hrs = 3.5 days


you would normaly take 80% of the time and allow 20% for losses.


so lets say its should run for 3days.

++++++++++++++++

One thing we do before departing on a camping expedition is get the cool box down to temp on the house mains and chill everything going in it - cooling those beers can sapp a lot of power!

Thanks for all the detailed information. I’m torn between the Ecoflow and the Bluetti, is there much between them in terms of quality? I quite liked the 30amp out on the Bluetti. Many thanks.

No idea about quality differences but...the ecoflow won't run any of my Dyson products even though there's plenty capacity to do so...it's something to do with Dyson use a frequency that lots of power banks and inverters don't like. 1800w Dyson...no, 2200w Lemington dryer, no problem.
