I have been researching for an off grid system. There is a lot of bollocks talked about this on line. I was reading an article today that a 12v 100ah lifepo4 battery would run a fridge freezer for 30 mins which means you would need a ridiculous amout of batteries to last 24 hours. This is the real deal so its answered a lot of qusetions for me. A lot of these fridges built before 2010 run between 600 - 700 watts or so. This was a really useful practical video. If I get into any debates with people who think they are experts I will direct them to this. I always say if you want to know anything look it up on youtube 😎😎

Exactly. 6.5 amps X 115 volts is 750 watts, but intermittently. So the room temp, how often you open the door and the condition of the door seal itself are widely variable. A better test would be to test a light bulb with the Kill A Watt tester, then run that eg. 100 watt bulb continuous until the battery is exhausted.

My fridge is 1996 Whirlpool 25cu.ft. with same 6.5A full load current, mine consume about 2.4kWh/day with freezer setting to "A', and fridge side to '2'. You have to factor in the inverter efficiency, 85% is typical, so if the load on AC side of the inverter is 1000W, that means the battery has to supply 1000W/0.85 = 1176W of power, that is the number you will use to determine the battery run time, I.E. if you run 1000W AC load for 1 hour, that will be 1kWh, that mean you will consume 1.176kWh from battery, if the battery is rated at 1kWh, then you will be able to run the fridge for 1 hour. Great video and looking forward to your next video,

A lot of this depends on how often people go in that fridge. During blackouts make sure no one is starring endlessly at the open fridge! My fridge goes to 700-800 watts when compressor kicks in thankfully its only for a very short time. It runs around 400 watts when defrosting and 104watts if its being opened up. If left alone it will stay at zero for very long periods. I have a Pecron EB2000 which stores 1980 watts lifepo4. It will run it for approximately 17 hours.

I need to run test each on a meter, as "run times" can really make a difference as to actual usage. If after that and I do verify that their is new tech that is making the new one much more efficient I'll change out the older one. When I can find one on black Friday special or such.

The quick and dirty way to a more efficient fridge is find a chest freezer and use an Inkbird temp controller (big with the homebrew community) to run at fridge temps. A great deal of waste comes from having a vertical door fridge that dumps all its cold air the instant it's opened. Also better insulated. Pro level is get a SunStar refrigerator from Living Energy Lights. Amish made, 12v SECOP compressor, 4.5" of insulation, runs directly off a 200w panel with NO battery and NO inverter. It's insulated enough to hold temp overnight. Now true they're $1200 for only 8 cu ft, but you're not buying a 100ah battery or inverter either. These fridges are being used to great effect in Puerto Rico where the grid is hot garbage and people regularly have to throw out food due to spoilage. 200w panel, SunStar, MC4 cable, done.

I didn't actually find the initial draw from the compressor when it kicks on, but knowing the fridge uses 750w when running I figured I should use an inverter that can handle 3x that.

With all the energy stuff here in the EU I am measuring my 22 year old Liebherr refrigurator at the moment. It's less tall , 1m 40cm (4 feet 7⅛ inches Google says). I average at 1.3KWh a day. A bit weird KWh(our) since we measure over 24 hours time. On home assistant I can also see what happens on a graph. It's at 115 Watt for sometimes 30 minutes or sometimes less and then it starts drawing around 80 Watt for like 2 hours and a bit. Then after that it draws like 0 Watt for 2 hours. If I check some of the new ones, bigger like 6 feet tall, they seem to draw far less. I have seen figures like 0.7KWh a day. So your father might also better invest in a new one. Also you have some draw and loss of that inverter.

@OffGridBasement Жыл бұрын

Yes, the inverter loss is very real. I tried to use an inverter just big enough to handle to initial draw. a 3000w inverter would be overkill for just a fridge. Your fridge doesn't seem too bad for how old it is! Thanks for the comment!

@EclecticBuddha Жыл бұрын

Try doing basic stuff like cleaning dust off of the condenser coil, make sure it gets good airflow, and check the door seal. Those two factors tend to kill the efficiency of most older fridges. Spending a bit for a thermal camera could find energy hogs too. It'll find drafts in your house, leaks around refrigerators or freezer doors, even electronics that consume a lot of standby power. It's interesting when you see a computer or gaming system that is "off" but still drawing power and putting off heat. Similarly, you can go eat a Kill A Watt, which you can plug appliances into to see how much power they use.

@Tore_Lund Жыл бұрын

If someone seriously considers running their fridge on battery power, then hacking the fridge for lower consumption is the way to go: Thick insulation on all sides (door looks like a vault door) and the condenser in the back exposed to outside air. Earth ship types of guys have done this and use 1/5 to 1/10 the energy depending on season.

@OffGridBasement Жыл бұрын

That's a bummer. Usually the BMS will only balance when charging. Is the overall battery capacity diminished? Do you have a way of testing that? What is the load? 50w? 100w?

My 4 Marine Lead acid Batteries will run my entire 120v electrical system in my house for two cloudy days as my solar panels will produce 150-200 watts per hour on rainy-overcast days. ; Frig, microwave, coffee maker, toaster oven, fans computers, internet routers, lights, tv's , hair dryer, etc. House has a background draw of 75-100watts at night , Frig 75 watts when running 35 watts per hour average when not opened, 200 watt/hrs for the frost free cycle. Batteries are 12v/120 amp hour, or 1440 watt/hours each, cost about $100 each. This is assuming we don't turn everything on at once like we do when we are on the grid. Propane/12v/120v RV Refrigerators are a huge power draw.

Example if you have two of those batteries in parallel and connected with at least 4 100W solar in series with a nice MPPT controller will that last even longer? sorry, I'm new here 😊

@OffGridBasement Жыл бұрын

Yes! Putting two batteries in parallel would double the run time. Adding a solar charge controller and 400w of solar would probably doulbe that run time again! On a nice sunny day, 400w of solar panels could get you another 1600 - 2000w! If you live in an area where it is mostly sunny all the time, this could run indefinitely.

Hey Jim, great video. 6.5A*115=750Watts 13V*100Ah=1300Wh. 1300Wh/750W=1.73 hours. 672min (total runtime)/102min (calculated runtime)=6.58. 60min/6.5=9.2min of compressor runtime per hour. This seems about right?

I calculated 45 mins at 1500w, based off one youtubers capacity test on a 200ah battery, it took him 16 hours to drain it with a 150w load. So it can run a 150w appliance ror 16 hours straight, or a 100ah battery could do that in 8 hours, not that much but rarely are you running at full load as this test shown. My 65w laptop, 70w monitor and 60w subwoofer shouldnt be able to run a 80w panel but it did on a sunny day the other day without draining my battery, the monitor was in power saving mode so probably was only using 20, the laptop in power savings mode as well and was still able to charge trickle charge my phone, although this seemed to be the limit, all while watching youtube videos. But In reality with a power sensitive system like solar you'd probably be wise using more power efficient appliances and could do more with a lot less.

@budmartin3344 Жыл бұрын

You have to factor in the inverter efficiency, 85% is typical, so if the load on AC side of the inverter is 1000W, that means the battery has to supply 1000W/0.85 = 1176W of power, that is the number you will use to determine the battery run time, I.E. if you run 1000W AC load for 1 hour, that will be 1kWh, that mean you will consume 1.176kWh from battery, if the battery is rated at 1kWh, then you will be able to run the fridge for 1 hour.

@cleversolarpower Жыл бұрын

@@budmartin3344 Yes, good thoughts. But I think this inverter will just take 1000watts in and put 850watts out. The components are made to transform 1000Watts of energy, not 1176watts. Then we have also the issue of VA or Watts output. The fridge is not a resistive load but inductive.

@budmartin3344 Жыл бұрын

@@cleversolarpower We are talking about input power and output power, to get 1000W of power output on the AC outlet of the inverter, the power input will be about 1176W of power that the battery has to supply, this is due to 85% inverter efficiency. It is easy enough to use KIll-a-Watt meter to look at the Wattage the fridge is using, VA will be higher due to power factor.
