Finally. Jesus, I have been all over the Internet to find this. A simple answer. Yes it can be done, here it is, was what I wanted
Glad to hear you found the answer 🤙
Same 👍 I knew it could just nobody says how long you can use it for.
I dont mean to be so offtopic but does anyone know of a way to get back into an Instagram account..?
I somehow forgot the password. I appreciate any tips you can offer me.
@Gregory Samson Instablaster =)
@Ashton Quincy I really appreciate your reply. I got to the site on google and I'm in the hacking process now.
Seems to take quite some time so I will reply here later when my account password hopefully is recovered.
One small detail ill add is that inverters come in 2 types modified sine wave (cheap) and pure sine wave (a bit more money). Its best to get a PSW inverter for running sensitive or more costly home appliances such as laptops, microwaves etc
Very simple mate! Most people don't get it. The whole "electrical" aspect is almost a foreign language to many isn't. Cheers
It is... thank you for watching, hope you subscribed 😀
Gold nugget video. Thanks so much.
Glad it was helpful!
Great video
Thank you...
Yes it works - you need 25mm square cross-section inverter leads as the current can hit 100a draw - We use a 105a Lithium Lifepo4 battery on ours
Where did you get your lithium from?
@@sausage6984 A nice chap who lives on the River Themes in a Barge just out London - He deals in bulk sales
@@trevortrevortsr2 thanks. Lithiums are very expensive.
@@sausage6984 Theres some pretty nice 280 Amp hr Lifepo4 on Amazon I would use if doing it again - you have to be careful some are "b" class read the feedback - I rebuilt my pack recently with a blue tooth BMS and fitted a little low watt 12v silicon heating pad under it with a related timer set to switch on at 2deg C so I can leave it connected to solar all year round even in sub zero - using mine at 10 - 90% charge there rated at 7,000 cycles to 80% - in the long run they work out cheaper - they will last over 10years
@@trevortrevortsr2 There's a lot to think about. Very useful info. Thank you. It takes a fair bit of digging to find info and then it's ambiguous for anyone who hasn't done an electrical principles course or there's data missing from specifications.
It annoys me that battery specification don't state their max amp output for max recommended time, before internal resistance becomes a heat problem.
As a simple rule, to calculate how long a 12v deep-cycle battery will last with an inverter multiply battery amp-hours (Ah) by 12 to find watt-hours, and divide by the load watts to find run time hours. Finally, multiply run time hours by 95% to account for inverter losses
One thing I would do is run my engine (split charge relay) while using the microwave.
What a no nonsense video .Great .What kind of inverter are you using ? Thanks again .Great vid!
Great video. I’m off to search Bodens web site and book my van in to you!
Thank you...
Great video :)
Thanks, hope you have subscribed 🤙
Thanks for video. It would be great if you could list which inverter, microwave, and battery you used. Did your inverter display the watts being used? Most microwaves are rated in cooking watts, not consumption
Hi Chris, The parts used are. LEOCH 12v 100ah Pure Lead Carbon Battery - EDECOA Power Inverter Rated Power 1500w & Serge Power 3000w - PANASONIC 800w Microwave.
On test we got the microwave to run off the fully charged battery for approximately 30 minuets.
Do you think a 800w inverter 1500w peak would run this?
Rob I’d say “no” because some microwaves actually startup at a higher wattage. For example 800 watt cooking equals 1600 watts inverter roughly.
A 110 life4po Battery will give you mins. Much safer at discharging higher amps.. you’ll also get a slight whine using a modified sign wave inverter. In my experience pure wave is better.
@@stellarandrews9538 I use this microwave ( amzn.to/2VbvkzB ) with my Victron 1200 Inverter ( amzn.to/2XDyuOh )
SerendipitySue are you in Europe or the USA. ? That makes a huge difference as US appliances use a different voltage to Europe.. I’ve also edited my comment to better explain
Epic! Would recommend 😎
Thank you
Like the video 😍. How many times can you charge a lead acid battery. I know a car battery normally last 3 years.👍🤔
We used is a pure lead carbon battery with fast charging of up to 90% in less than 1 hour and has 2000 charge cycles
No one has ever been able explain to me what a "bat tree" is.
Honda eu22i silent generator 2200w at the pull of a cord ? By the time you carry that big battery around and you buy a quality inverter you can have a honda suitcase generator which you can keep in cupboard in house ?
Great video. Would a renogogy 100amh battery do the trick?
Sorry we haven’t tested a renogogy battery so can’t really answer.
@@BodansCampervans thx!
What size fuse is on the inverter.....100amp... 200amp...?
I found 200amp fuses best as threes quite an initial surge that tripped a 100amp
Hi, I'm very new at this so...Amish here in Missouri suggested that I get 2- 6vot. battery's for running LED lighting, computer, and Microwave, Is that true ? Also will I need some kind of converter......I did notice "Bass Pro" had some that was multipurpose...but I'm still kinda lost to all this.
Hi John, we have tried many different setups to get a microwave to work from a 12v battery and found this to be the best. As for LED lighting, so long as its 12v, a standard 12v leisure battery would be fine without an inverter. To run a computer / Laptop you would need a 300 watt inverter conectected to again a standad 12v leisure battery. Hope this helps.
Hey there I have
varta professional dual purpose lfd90 battery
Sterling 1600W power inverter
I've noticed that voltage on the inverter drops to below 12V when I use my 700W microwave. Cables are very thick I put 50mm so I believe that not the problem. Could battery be of a wrong type ? Does voltage on your inverter drops as well ?
Thanks
Wanted to know how many cranking amps is that 12 volt battery? Thank You!
Hi Alan the battery is a 100amps
What's the smallest size battery you can use to power that microwave?
I wouldn't recommend anything smaller than 100amps lithium
Question please how much will it help to have engine running whilst microwave is running. Will it make much difference? subject to that battery being on the charging circuit. ThanksTony
Hi Tony, it will help but only slightly and its all dependant on the size of your vehicles alternator and condition of you vehicle battery. For this to work properly you will need it to run from a lithium or carbon/lead leisure battery.
What are the options of how to charge the battery? Is a 12v marine battery the best type for this application? Thanks
Hi Cyti if the system is going into a motorhome or campervan we would be charging the battery using a votronic battery to battery charger which charges the 2nd battery whilst driving the vehicle and when you can hook the vehicle up to mains power we would recommend a Numax battery charger.
So can that inverter hook up to my normal van battery? won’t be using the microwave a lot. I take it the vans alternator charges the battery?
Hi Aidan, I wouldn’t recommend connecting an inverter to your vehicle battery especially a high powered one as it will drain your van battery very quickly to a point that you won’t be able to start your engine. Alway try and connect to a second battery that can be charged from your vehicle.
@@BodansCampervans okay thank you for replying. I’ll have a looky
Which are the best products?
Hello, I would like a setup like this, but I haven't bought an inverter yet. Would you expect this to work with any leisure battery over 100AH? I've got a SuperBatt DT120 120AH battery. I've noticed recently when I use my 45watt laptop charger the battery voltage drops to around 11v. I'm worried that the battery isn't going to be able to maintain a high enough voltage when it's having 600watt drawn from it?? Don't want to waste a lot of money on an inverter if it isn't going to work. What are your thoughts?
Hi Sam, we have tested several batteries and found the LEOCH 12v 100ah Pure Lead Carbon Battery to be the best and last the longest, we have not tested the SuperBatt DT120 and my feeling would be that it would be not suitable for this job.
I feel a carbon lead battery is the key to this. I guess a " cheap " calcium battery wouldn't last that long.
Yes you are right as we have tested many and found this to be the best for the job.
Hi the 800w is that the cooking power of the microwave as I’ve be lead to believe they draw more than that???
Mines 800w and draws 1184w according to the inverter.
Can I run a microwave in my car with the engine running? I only need to heat food up for a few minutes.
Hi Robert, sorry i'm not sure if that will work as testing has only been done on our equiment.
How many volts is the inverter you are using?
The inverter is 240v and 1500w
Please share amazon URL for this invertor.
Hi Jayant, this is the inverter we used.
www.amazon.co.uk/EDECOA-Inverter-Vehicle-withLCD-Display/dp/B00WW8SQUE/ref=sr_1_13?crid=1HC3E6MGI8TSQ&dchild=1&keywords=1500w+pure+sine+wave+inverter+12v&qid=1629888993&sprefix=1500w%2Caps%2C218&sr=8-13
I find it's easier to carry a 100 foot power extension cord and plug into someone's house
Sure you might only get 2-3 minutes cook time before the owner comes out asking what you're doing but mmm spaghettios are good luke warm anyway
:)
Love your comment
Could I do the same with a hair dryer?
Yes, so long as its a small low wattage hair dryer should work fine max 1200w like this www.argos.co.uk/product/9312201?clickSR=slp:term:travel%20hair%20dryer:1:46:1
Can my car engine be used to recharge the battery ?
Hi Richard, yes your vehicle battery can charge the leisure battery. To do this you would need a battery to battery charger such as a Votronic 3324. See link below. www.roadpro.co.uk/product/02d-battery-to-battery-dc-dc-battery-chargers/votronic-3324-battery-to-battery-charger-vcc-1212-30-c85065
yeah, how did you cilip it to the battery. and what's going on in the back of the inverter. not as helpful as id wished
Hi, the video was only intended to show that a microwave can be run off a 12v battery and not an in-depth instruction on setup sorry.
@@BodansCampervans thankx for reply - i ended up buying an inverter; i thought i needed speciality cables, lengths, and density. turns out inverters come with their own cables and clamps. funnily my title searches never matched up with vids available - but you tried. thank you.
what type of inverter is that? The brand name.
Hi, The inverter used was a Edecoa 1500w power inverter.
www.amazon.co.uk/EDECOA-Inverter-Vehicle-withLCD-Display/dp/B00WW8SQUE
Is that a pure or modified sin wave
Hi Mike, its a pure sine ware inverter
@@BodansCampervans What make and brand is the inverter? :-)
Hi I have tried this with a 6000w inverter with a 600w microwave and it trips so won’t run the microwave any advice please?
You need a 1500 watt pure sine inverter.
Great, Thank you
a 6000w inverter should easy run a 600w microave
@@irenedunne352 some cheap chinese modified wave inverters are dreadfully over rated - I opened one once - i doubt it could sustain 1kw
What is the amo hours of the battery
100 amp hours
now im hungry :/
you can't beat a ready meal :)
Have you got a link for the best cable to use? Cheers
Hi Dale have you tried Halfords www.halfords.com/motoring/battery-maintenance/battery-accessories/halfords-positive-battery-cable-60cm-24in-165316.html
Would any microwave 800w or below be ok to use in this set up?
yes any microwave rated 800w or below is fine so long as the inverter is rated at 1500w
@@BodansCampervans what size would you recommend for power consumption? Or does it not really matter
Hi again! Cranking amps. My car is 750 cranking amps. Are you sure your battery is only 100 cranking amps. That's not even enough to start any car. What did your battery come out of.
Hi Alan, it is a pure lead carbon leisure battery designed only for Campervans & Motorhome’s and not designed for starting vehicles. The battery does not have a crank rating as it’s designed for giving out a constant smooth power supplying power to all 12v appliances in the living area of the Motorhome.
Cranking amps are not specifically applicable to leisure batteries. Amp hours are what you need to consider for measuring leisure batteries.
