- In this third episode, we finally solve the mystery as to why this stubborn fridge will not run on our basic equipment. I had to break out the big guns for these tests but it was worth it. Now maybe we can move forward with testing and I definitely learned a thing or two.
I love your ideas on your channel! I have the exact same interests you do, and this helps me improve my ideas as well! I just wanted to tell you that your intuitive motivation is amazing, and that I love the creativity!
Need some 120v capacitors or "Run/Start Capacitors" to assist in smoothing of the surge current upon startup.
Thank you!! I couldn't figure out why my 1.7cu ft igloo dorm fridge would not run with my 500watt inverter. Now I know....need to get a higher watt inverter!
THANK YOU !!!
approximately 1.5 amp multiplied by 110 volt= 160 watts multiplied by 24 hours and 20% duty cycle is 800 watt-hour of energy for one day. 2 battery of 100 amp-hour= 200 amp-hour multiplied by 12 volt= 2400 watt-hour inside the battery but we can use only 50% if it is a deep cycle AGM so 2400/2=1200 watt-hour so we have enough energy inside the battery bank to run the fridge for one day. 2 solar panel of 100 watt with sun for 4 hours is 2 x 100 x 4 = 800 watt hour so we will be able to recharge the batteries with 4 hours of sun.
Thanks for the video! I was thinking about exactly this problem, what it would take to run a small frig. Looks like the answer is a lot!
Supco hard start capacitor.
I also found it makes a huge difference if you run pure sine wave inverters fridges and microwaves need pure sine wave power
I had a similar problem with an icemaker on my inverters. I surge protector resolved it!
From the first video I figured that was the batteries because it went under voltage . I would have never guessed you needed that big of a inverter to get going but compressors always take a lot amps startup . but you just like me something's bothering you you gotta figure it out. I'm glad you worked it out too bad it can be cheaper to do it
from my experience adding a big capacitor before the inverter with a diode on the neg side so the power doesnt feedback into the battery. that should solve the hard start issue. it works with big car audio amps so we tried it on my motorhomes ac, worked like a charm.
Would love to see a revisit with a solar panel!
How many solar panels are you using how much walts does your pannel produce...?
You need probably about 1500-2000 max watts just to kick the fridge on.
I use a different brand than the kill a watt, but it will show max watts pulled, though not sure how well it can catch a motor startup spike (it was only $15). For my fridge, the watt meter shows high/peak of 826 and it uses on average 108 watts while running (ranges from 96-170). If your watt meter does show high/low values, then for future tests, you can always reset it, then plug the device into a regular outlet to find out the average and max watts needed before trying it on battery/solar.
I've always brought coolers/ice for camping trips and think its time to upgrade to a portable refrigerator which are very expensive and then I came across your video...mini frig's are way cheaper. Would this work with only one of those batteries?
Have you tried doing this to a full size residential refrigerator? I wonder how big the battery and inverter would have to be. Thanks for the info
These are perfect for me. Thank you
Got old APC SmartUPS 1000 (670W) for free and it works fine with my normal size fridge. Need add fan also.
What is super cab in line on the positive side of the batteries for the surge
