Running 12V fridge/etc (1 Viewer)

[trailman7]

Last paragraph tells you how to initiate the hybrid system staying on for camping mode/continuous cycling of engine to recharge the battery as needed.

I plan on running mine off the 12v battery in the back of the LandCruiser. Engel has a hardware kit for DC. One small hole in the side panel. Inline fuse on cord and plug it in. I have an Engel 45 Fridge/Freezer AC/DC. ,My Hurricane back up kit.

I run my 15 year old Engle off my lawn mower batteries. Since I'm not home to mow the lawn it's a good approach. I'll probably continue this approach with the LC even considering the additional choices now available.

Most staring batteries are at risk running a cooler overnight.

I somewhat doubt the car would have an auto start feature. Imagine leaving your fridge on and it’s draining your hybrid battery, then the engine starts but you’re parked in the garage at home.

How does the F-150 get by this issue to recharge its battery?

LC does have an auto start feature.

Does anyone know how one would pass 120v AC outside the truck without leaving a door or window cracked open?

At 15 minute mark they talk about the inverter setup on the Tacoma Trailhunter, I know its not a LC but it is the same system. They state the engine turns on/off so the battery doesn't deplete. Running it fully open for one hour only costs you 3/4 gallon of fuel. BTW is the 2400W inverter pure sine wave?

The 1500 watt inverter is, so I expect the 2400 watt to be.

Wow that’s terrible efficiency. 2400wh for 3/4 gal of gas! That almost can’t be right as a carbureted a Honda Eu2000i genny runs for 4hrs at 2000 watt load. Unless a 2.4kw load keeps the ICE on like a regular non hybrid? In our Sienna hybrid I can run AC on full blast and the inverter at 500 watts and the engine isn’t always on.

We've been eyeing the Deltas for a long time. Especially with their crazy sales and that alternator charger option, it's real tempting.

My biggest remaining issue is charging that thing. For most cars, it works great if you remove it from the car and plug it into the wall (or run an extension cord into your car overnight to charge). But what happens when you forget that in your pre-trip planning and you've got a battery at 20% that charges 1% per hour via the 100W DC socket in the car?

The 250 has that awesome AC port, but same question applies: how often are you going to forget that you should have clicked that AC button on when you departed? Or maybe you remembered when you left your driveway, but got gas 5 miles in and forgot to click it again when you left the gas station?

If we can get the all in one banks to be very nearly as care-free as the dual battery setups, they'll take over the space immediately. We'll be watching this very closely as it seems we (collectively) are so close to having this sorted out - but we're not there yet.

It’s second nature for me. Start the rig, start the inverter. If I have a long drive I even reduce the charge rate. If I need a bump I raise the rate. I usually charge in the morning as the batteries are perfect temp to charge. Been doing it since 2021

My River 2 Pro goes 3-4 days in the winter/fall and 24-36hrs in the summer. If you’re that concerned with forgetting just get a bigger battery. I suspect a Delta 2 would add 1-2 days, Delta 2 max with 2kw you can probably go a week in Spring/winter/fall.

You can also always have 12v that’s automatic as a topper. Or a DC to DC charger from the 12v battery directly into stand alone LFP battery.

But that will end up costing what a Delta 2 costs. I still rather have a Delta 2 because now you have 2 inverters and 2 sources of battery power. Run a 12v heated blanket all night with the car off. In a ground tent, etc

Run the cord thru a drain hole, fuel filler door or perhaps the front grill like they do for engine block heaters?????

Maybe this?

For now I just plugged my Engle in the 12v port on the back of the center console. Yes it’s only on while ignition hot. Will run this way for now but need to decide on a constant power supply.

I have the same old Engle. It should run well plugged into a small 250wh power station that is plugged into the 12v or 120v. I'm not liking only one 12v plug

Yah, I’m aware. Just deciding if I want to do that or simply tap off the starting battery in the rear quarter panel. Weighing my comfort of risk with a fridge that runs until its power supply is completely depleted.

At least with the battery in the rear quarter panel that should make it easier to put a lithium iron phosphate battery in place of the original. As long as it has the ability to start the vehicle I don't see why not. If you did that you could really boost the capacity if you were to tap into it.

yup, all in the thought process. Tapping in super easy and the logical solution. I could swap in a fridge with a low voltage cut off but my NL60 is way bigger and lives in the 80.

If the fridge lives in the vehicle full time from experience the 500-720wh (specifically the EcoFlow River Pro that can charge up to 940 watts) is the sweet spot unless you live somewhere cold.

The small power stations cannot handle 24hrs in the Southwest. Unless driven daily/fully charged in the afternoon.

The problem with a LFP swap, is unless you have one specifically made for replacing a starter battery like the very expensive Dakota it won’t provide enough voltage to fully charge the LFP.

With the available space you’d still have less capacity than a standalone unit.

You can add a low voltage cutoff before the fridge and dial in the voltage.

For reference, my EcoFlow River Pro runs the ARB 50q fridge for 3.25 days straight.

I have an extra slide laying around. I need to see how it looks on the floor of the cargo area. It's sized for my NL60. If it fits between the two OEM cubbies I may try to mount that and fit a power station on the slide with the fridge. The external voltage option saves my starting battery but does not keep food cold. I daily drive this thing but still need to to run a couple days if possible. I could mount a small solar panel but I'm not looking to dive down that rabbit hole. I still have my built 80 and it's my primary wheeling truck. This is more like the princess's camping chariot when she comes along. Otherwise it's just my rig I drive for work and haul groceries home 30min from town.

Not the Southwest but you couldn't tell based on the recent weather.
