I’m setting up a Renogy 1000w inverter with a Arctic King mini fridge running .85a 115v in my van, and despite knowing it should work, I’m holding my breath until it is... lol
Great info!! Thanks! My freezer claims to be 150w so like you, I thought my 300w inverter would work… but NOW I won’t try that. Lol. I’ll check the compressor wattage for proper inverter! Thanks again!
Great video!! I rcently bought a cheap 1500W modified 12v inverter and MY WORD!! im impressed!! It powers even a 2hp air compressor!! its around 0,68kg too!!! Inverters are the best!! THANKS FOR THE FRIDGES VS INVERTER HEADS UP!!
Thank you! You actually explained a lot of main details I was looking for on which inverter is good for a refrigerator. The only video I could find with this type of info. Thank you!
@@glorytooneandonlygod3871 it's usually more of a DIY thing unless you want to spend 1k on a module, but the easiest way is to get an AC motor speed controller and use an Arduino to basically turn the speed from 0 to 100% over a second or so to reduce the massive inrush. I'm sure there are other solutions out there cheaper but I haven't really looked for a while.
Wouldn't it help if one used an inverter with a short power peak that can handle the initial startup? On A/C condensers that's a common issue as well but there's a Hard Start Kit that can help which works like a large capacitor which gives it that jolt of electricity.
So you have hooked up a normal fridge to a cheap converter. When I check “official” websites, they all say you need a pure sine wave. Yet here you are, with a modified sine wave converter and it seems to work fine. Is it really needed to spend the extra cash on an expensive converter, or will cheaper options do the trick as well? Curious as to hear your thoughts on this.
mate i've had a 600w 20+ years old inverter using power tools and everything. back then i had no idea what the pure or sine waves meant. but i used it anyway and it never stressed me.
wired directly on the larger inverter that worked. The cabin has a couple cigarette lighter outlets that work with the small inverter with small devices.
So the one you got now. Is it like the 150watt one but just higher power ? 600 or 750watt ? Can those run continuously without issues? I recently bought an 12v pure sine wave inverter but not sure if they only meant to run a few hours or so if there is power issues or if low load like 100watt or 200watt can be run 24/7
I want the link of .. the fridge ! please, thank you. Inverters also have surge and actual wattage, sellers tend to give the surge (max) watts rather than the actual watts, that is an advertised 3000 W inverter = not more than 750 W real performance. So you need to get one with a surge that matches your fridge initial start, and with watts that the fridge normally uses, 2 parameters to consider.
That initial amount of electricity needed to get the system up and running is called SURGE.Ever notice it takes more energy to start your car than it does to run it,this is the same principle
I have motor and compressor appliances with total load of 1000 Watts ? Should my inverter sizing be 300% i.e 3000 watts and also over-estimation for safety by 130% or 1.3 = 3900 Watts necessary ?
Let me share my experience after I watched this video and tried that to my 110w fridge, with a 1000w cheap inverter. As you said, it took some time to build up the pressure, failing and failing, but after some time it did start and kept going until I saw the usual performance of the fridge. Day two all good and i lowered the thermostat of the fridge. Day 3 tho... The fridge was not able to keep running more than a minute and some safety relay was cutting it off. I checked the compressor and it very hot, also the pipes. I let it cool down for a day and tried again. Same thing. I tried to push some air with a fan to see if it helps but no. So now I believe that it may work yes. But it does damage to the fridge. I can't try to run it run it from a generator at the moment, but I will and that should tell us if the fridge is damaged for good.
@@Hoppervision 110 watt. There is another thing that is going on with the inverter, so I hope the fridge is still alive. Before I used this inverter for the fridge, I was using it to power a small pc, TV etc. There was a lot of noise coming from the transformers but they were working. Well they used to work.. Now they don't work. There's no noise, so something is happening with the wave, and the output voltage drops hugely when I connect them. Strange thing is that a fan, a coffee mixer and some other devices are working well.... I don't know.. I guess I'm going for a much much decent pure wave 4kw. I hope that could power a fridge and a portable a/c.
@@EX_WIZARD_YT don't believe that 110 watt rating because that is like 1 amp on a 120 volt grid. Super unrealistic. A compressor is a heavy demand for amps. For a fridge I would consider at least a 15 amp x 120 volt power consumption for the start up. So minimum 1800 watt converter with power surge up to 3000 watts. You need a 2k inverter for a refrigerator.
My experience with a 25 yr old Full Size GE Fridge & Top Freezer 250 W: I use battery bank total 2400 Wh (100Amp x 12 V times two battery connected parallel) and 3000 W Pure Sine Wave Inverter from Amazon for $55. The compressor started briefly with a fan noise from the Inverter and it died. I could not get it run for more than 10 sec max. I think the problem is I don't have enough battery juice to meet the 10X power surge. It needs at least 2500 Wh & more to get the compressor started. I must add another battery so that I have enough juice much more than the bare minimum of 2500 Wh. Once the compressor picks up steadily, then it needs only 250 W for 10 hr when you can recharge with the solar panels or wall power! Probably, I need also a larger Inverter Pure Sine 5000 W which costs $150 or more!
Hi I'm trying to charge up my 300a black+decker jump starter with a 100w inverter cigarette lighter plug in but idk I don't think it's charging please help.
Pure sine wave or go ahead & fry the electronics. I know cause its happened twice to me using cheap Modified sine wave inverters. Youll learn the EXPENSIVE way.
Yes. I've seen other videos saying the same. I definitely don't want to ruin a $1200 fridge, to save $100 of food when power goes out. Can you recommend an inverter?
heheh you didnt' account for inrush current for starting the compressor, ooopsies. ind you, no fridge I've ever seen has this anywhere, you have to put on a power meter and monitor it. Giandel 1000w just to be safe.
@@Hoppervision it was a TLDR comment, not a criticism :P checked my fridge last night, 986w inrush current. eek. and a "GOOD" inverter is freaking expensive :( but I have a crap load of batteries on float charge doing nothing and it annoys me wahh i.imgur.com/ek5dzZt.jpg 45 from my server UPS waiting for me to get renovations far enough along to install it.

Modified sine wave for a fridge?
I thought pure sine was the only way for motors
Actually that helped out alot, thank you
Much appreciated. I was trying to figure out if it would be viable to power one with a Milwaukee Top Off.
Thank you! You actually explained a lot of main details I was looking for on which inverter is good for a refrigerator. The only video I could find with this type of info. Thank you!
Install a soft start on the fridge, people use them for running ac's off grid, they just take the massive inrush out
Any suggestions, links from where to buy it ? are they expensive?

@@exogator Thank you very much , such a h helpful video. I wish someone can make it and sell to people.
@@Hoppervision I'd honestly just integrate it into the appliance and use it's frame as the heatsink, I mean it's not like it would affect it much
How long does the battery last, im new at this, and want to get a mini fridge and inveter for our off the grid cabin
About two days if you disconnect the solar. With solar, 10 years.
Wouldn't it help if one used an inverter with a short power peak that can handle the initial startup? On A/C condensers that's a common issue as well but there's a Hard Start Kit that can help which works like a large capacitor which gives it that jolt of electricity.
There's probably stuff like that out there, but for me it was easier to just buy a bigger inverter for cheap.
can you run a full size refrigerator on a 600 watt generator ?
No you can not. You need a 2000 watt generator to start that compressor. 15 amps

long story short, the startup surge can be as high as 5 amp in larger refrigerators - which is about 600 watts. size accordingly
That is for tiny refrigerator, a normal household refrigerator would be 12 to 15amps to start
Both of you are wrong....
Need to consider solar inverters. they can easily get the surge capacity of the system to a respectable a respectable level.
That's cool to know

Every motor is like that it have start point which is much high
Video was good
Refrigerator do surge you need to multiply it's power by 4 before choosing your inverter
Probably had to charge the start capacitor
