Yes and No!

Yes, the Honda has ample capacity to supply power to the fridge.

No, because you should run the fridge from a battery, then use the Honda to maintain a charge in the battery via a 240v to 12 volt battery charger.

A practical way is to use an AGM battery with a capacity of around 100Ah-120Ah. This will give sufficient power to run your fridge constantly over a 24 hour period, but only require the Gennie to re-charge the battery over a two to three hour period, depending on the capacity of the battery charger you also need.

The Engel will also run off 240. Why not simply plug the fridge into the 240 outlet on the gennie.

At this time crank the fridge up whilst it is getting 240, and charge the battery whilst it is not having anything drawn from it. This way the battery charges faster and the fridge is well below the desired temp and thus will draw less when switched back to run from the batt.

Works for me.

Cheers,

Jim.

Yes,

You are quite right Jim.

I assume that the fridge would have already been running on 240 volts before the trip had begun and it was simply a matter of keeping it operating.

The logic is still similar, the one difference being those of us who choose solar panels to keep the battery charged rather than have the need for a generator and charger at all.

My backup "generator" is the vehicle alternator and I have two auxiliary batteries. One in the car and one portable battery system.

Jim,
You suggest "At this time crank the fridge up whilst it is getting 240.....his way the fridge is well below the desired temp"

If the fridge is "cranked up" as in the fridge cabinet temperature is turned down lower, any food in it may spoil by being too cold or possibly freezing !!

I would recommend leaving the fridge at the 'desired' temperature !!
Maybe get an extra AGM Deep Cycle battery to share the electrical load.

Food may spoil by being too cold?

Ah....the process of freezing actually peolongs the life of fersh food.

Chilled foods last a lot longer at 0 than +4.

Basic biology, bacteria breeds slower the lower the temperature.

Please tell me of a foodstuff that goes "off" faster in a colder atmosphere? And don't quote me lettuce or tomato, they don't go "off", they simply freeze and then lose their water content upon defrosting.

Jim.

Jim

The food may not be spoilt by bacteria, but if it is wrecked by freezing it is still spoilt.

What the above post says regard running your fridge through a battery is basic ley correct. However,that was the general rule in days gone by when gen sets voltage was only governed by a throttle setting. Generators like the Honda you have are not a problem and will run your fridge direct, in fact the EU10 would run several 60L Engel's...Regards,,, Foxhound(WA)

Yes the gen set will run the fridge direct but you have to fire it up every hour or so to keep it cool. With a battery and charger you only have to run the gen set once a day. You will also run the fridge at a more even temperature if you have continuous power to the fridge and let its thermostat do the controlling and not rely upon your memory.

I use my equivalent sized Yamaha gen to run the fridge directly off the AC 240v and recharge the battery at the same time via a charger.

Same here... Yammie 1000, same as Honda etc.

The very first time I used the Yammie was at a gathering for Xmas (2006 I think), down by the Murray River at Monteith near Murray Bridge.

It was very hot and there were a few blokes who had fridges that were struggling. With a couple of powerboards and extension cords, I was impressed with the load we had on the little gennie and it barely revved up (except when Pesty's massive 110 litre Waeco cut-in).

I was running:

Pesty's 110 litre Waeco,
Brew 69's Waeco (60 litre I think)
Muddy Doh's Waeco (50 litre?)
My Engel 60 litre in the Patrol
My 100 litre Engel upright in the Ultimate Camper
3 x battery chargers.

So, I don't think you'll have any worries with running your fridge/freezer....... hahahahaha

Whoops.... small correction.... the Engel in my Patrol is only 40 litre; not 60.

Sorry.

Thats good to know Roachie. I would never have guessed my Yammy could do all that:)

The problem IMHO is that running your fridge on the EU10 is not optinal for the generator (some would say lessens the life of the engine) as it is not running anywhere near load. Sort of like using a sledgehammer to break a wine glass. Battery is a far energy efficient and fuel saving option with the generator charginng the battery once or twice a day for an hour or so through a decent 240v 4 stage charger (matched to the type and size of battery). yeah i know, you buy a $1,400 generator then someone says ... but them's the breaks. And of course, this is only an opinion.

If you don't care about longevity of the engine, or the small price of running it all day, then yeah, ignore all and go the Engel and the EU.

Yes it can, we ran ours on on freezer to save some of our frozen food when we had a power outage for more than 24hrs. Hubby also used it for his laptop at the same time, but I said no to the TV because it would meant the powering the other stuff it runs through (dvd recorder, sat receiver box etc etc).

But for a camping set up ultimately what has been said is correct, run the fridge off a battery or two. In the end we found it was ideal to have it hooked up to the aux battery in the car as we tend to go for drives away from the campsite thus charging the battery up (also handy having food with ya), and we carried the gennie as a back up measure. We did also invest in a good battery charger - to charge the fridge battery & others in the camper trailer, so along with the gennie this was also a good back up measure should the main vehicle battery ever go flat.

But in those people who are saying that running the fridge would be bad for the engine because it's being underworked, well surely the same applies when you're running a battery charger to charge batteries - I can't imagine that would draw any more power from the gennie. Of course I realize that in that case you're only doing it for say 3hrs or so at a time (depending how many batteries you need to charge), and maybe once every three days.

My Jaystar 25amphour charger running full bore _Affordable_Storage_Drawers.aspx 250watts, I figure this is a reasonable workout for my 1000w EFI generator and won't lead to a scored bore. Quite different to our fridges that tend to draw around the 60w mark when drawing 3.5amphours from any source. Will admit am on the end of a bottle of white tonight so if i am misleading am happy to be corrected, but I did just check the 4 stage charger.

The 1700i Subaru will run a 20A 24Volt charger on echo .
At 25A 24Volt it is just above echo capacity.
Using the above on full power we got 6.5Hrs running so thats 150AH.
Using Inverter Hondas Yamahas and Subarus to charge batteries is the most economical way of using an AC generator and can be up to 400% more efficient less run time less fuel less wear and tear.

I had problems with my 1kva, as they have an alloy bore, carbon had scored it even though l had done all the proper services. After some arguing with Honda they eventually paid half the repair bill,one year later problems again so I traded it in on the eu20i. The problem was directly caused by me running my generator for long periods running a bar fridge when camping, I now have 12v fridges and batteries.
