I cannot be held responsible for this information.
Not all refrigerator use a pumpWhat do you think a refrigerator is?
Some use Absorption systeem.
And are still beult today .

You are correct though I could argue that absorption based refrigeration is still a pump. Just not mechanical.Not all refrigerator use a pump

Yes but it works with heat and cooling.You are correct though I could argue that absorption based refrigeration is still a pump. Just not mechanical.
Ok, fine and dandy.Yes but it works with heat and cooling.
Means it nature way and thare is no big pull on the systeem.
Most use 10/15 ampère and will not have spike pull like a compressor model
That is the reason those systeem can work on lpg or propaan .
Than it do not use electric power .
Thought I would update my information so it can be used in assisting me in my questions:How are you measuring voltage, what make is the 280Ah battery, Renogy perhaps?
Are you measuring the voltage with the battery under load ?
Is the inverter permantly connected and switched on?
What make and model is the inverter?
What is the load on the system.?
How are you charging the battery, what equipment?
How are you determining the battery is fully charged?
Even a small load on the battery will reduce the voltage from the 'completely full' value.
The fact that the battery will not meet the night time loads suggests that either the battery is not being charged correctly, or the load is too high for the batteries capacity.
I'm not sure if I don't understand. I have a Refrigerator, the thing you put milk or ice cream in and hope to keep if cold and fresh. Nothing more, just two simple refrigerators I have in my home, I assume many people put in their homes, so that when you come home from the grocery store that you can put the 'cold' items in to so they will keep cold and fresh.Yes but it works with heat and cooling.

And I'd like to add. The WHOLE reason I came on this site and asked my initial question was to find out if anyone can help me why my system, just installed less than two months ago so brand new, ran for the first week to ten days (with all the same items on the load) and I never even thought nor used a battery charger and it all ran off the solar panels. NOTHING else changed. The same summer sunny days nearly every single day have been the same also. Then I'm seeing my battery voltage so low one night that I began charging the battery every night, and seem to have to charge every night, to keep it all from cutting off completely (Inverter losing enough voltage to keep running and just turn off). Seems so odd when there doesn't seem to be any logical reason for this to completely change like that! What went wrong? I don't know if any 'absorption' thing has anything whatsoever to do with why this changed. Maybe I am just not getting this absorption thing or something?I'm not sure if I don't understand.

I don't know anything about 'absorption' anything. So can't figure out what it is you are telling me.
In 74 years on this planet, just have used refrigerators and if there is some 'absorption' device have never went to the store and bought one of those, just bought a refrigerator for my home for my cold food. I think everyone I know has done the same, all during the 74 years here. Don't know nor have ever heard of buying an 'absorption' machine or the such and don't know anyone that has such a thing.
The problem is something did change. The fact it worked for the first week could have just been that the amount of charge your battery was getting kept it from being discharged but never was enough to fully charge it back up. Think of it like a 100 gallon tank of water. Every day you use 20 gallons of water and you put back in 10 gallons. Things are great you have water but after 10 days you go to get water form your tank and it is empty....

NOTHING else changed. ....
13.30 loaded after charging is reasonably normal. Might hang at 13.4-13.5 if resting no load. I also recommend 14.0 to 14.2 charging.
Ultimately need a second battery or even two more.
I can't give any direct recommendation on a brand as I built my batteries myself by ordering cells and BMS separate.And what suggestion would be a good battery? I'm thinking of adding a 300 AH battery to add to my 12.8 V 280 AH battery. If you have some ideas could you also say why you would suggest a particular one? There seem to be a gazillion out there and prices in the mid $400's all the way up to $1700 !!
Thanks
Didn't respond to your question about load so here is my setup:You did not mention how much load you put on it overnight.
Something also to consider is if a large load (such as a pump or compressor) cycles on when the battery is at a low state of capacity. The resulting voltage slump can cause your inverter to trip out on low voltage. Once it does the battery voltage jumps back up to resting voltage corresponding to actual capacity left.
Yes I know you posted it before. I would suggest removing the battery from the setup and putting a charger on it for at least a day (even if it indicates charged keep it going for the whole 24 hours). Report back with the resting voltage of the battery after a few hours of off charge and not connected to anything (taken with a DMM that you should have).Didn't respond to your question about load so here is my setup:
Everything is on, everything below is connected to the 3,000 Watt Inverter, all brand new build and equipment, cool house, not hot at night, and solar panels getting near full sun each and every day:
1 Internet Router ~ 20 watts at most ever under any condition
1 Computer system ~ 90 watts on standby at night or at most ~180 watts in use
1 Refrigerator that may come on during the night ~110 Watts (may or may not come on during the night when no solar cell input)
1 Refrigerator that may come on during the night ~ 120 Watts (may or may not come on during the night when no solar cell input)
1 TV system / DVR / etc that is off but on standby ~ 30 Watts and at most ~100 watts when watching TV
BougeRV 200 Watt Solar Panels (four each, wired in Parallel) - BRAND NEW
BougeRV 60 Amp MPPT Controller - BRAND NEW
BougeRV 3,000 Watt Inverter - BRAND NEW
ECO-WORTHY 12.8 V 280 AH LiFePO4 Battery - BRAND NEW
Physical Layout of Equipment attached (although there is an additional 3,000 Watt Inverter in the photo not currently attached)
Hope this is clearer of my setup.
A refrigerator, the same thing probably most homes on the planet have (less I suppose homes in the middle of Africa).What do you think a refrigerator is?
Only cutting open the battery (Eco-Worthy 12.8 V 280 AH) to get to the BMS would allow me to measure anything.If you can connect to the battery BMS then it will give you the data. Save your dollars, add more solar, or decrease your loads.
And I know that I may sound facetious, but I truly do wonder about all this. My INITIAL question to this entire problem is that why did everything run for over a week, out of the box brand new everything, never needing to do any charging, yet now I have to run a charger every single night just to keep the inverter from powering off from lack of voltage in the middle of the night!!!! And the sunny all days haven't changed (although today we actually have some marine layer and clouds - unusual). You see, all these questions about a refrigerator, or anything else I have, are simple common everyday every home things! And they just didn't evolve into something else between week one and now afterward. There is nothing I can figure out that answers this and why I'm asking all you experts.A refrigerator, the same thing probably most homes on the planet have (less I suppose homes in the middle of Africa).
