will work perfectly with mine solar settings .
I paid half down and they ordered , I am cooked .
A lot of money everything together, a lot .
In meantime, batteries went down to 59 % (yes, after use/abuse), and it took
2 full days of rather sunny times, and of almost not using anything ,
to bring them back to 97%,
where they are know , and going slowly higher
I started ask on forums, and two people told me I should forget about fridge .
I am so terribly sorry for money already spend for all this,
literally fortune .
Please tell me if I would have two more batteries, would this fridge
work ?
I know, this is my desperation, and why I am looking for second, third opinion, but I really can not understand, why places which sell
this fridges, sell much bigger ones, with two Troyan batteries and two panels as the operating kit .
One more ,
my Controller, Steca PR2020, 12-24 V, 20 A
1) You don't mention the total amp/hr capacity of the gel-cell batts (batt link doesn't work), but having a Solar refer with only two batteries may not be practical. Flooded wet cells or AGM's would likely preform better than gel (JMO). Because of the addition of the refer (refer link doesn't work,) more than likely you'll need more batteries. More info is needed on the refer.
2) Could be that you're experiencing concurrent failures, possible a bad inverter, or simply low battery voltage (batts run-down; too much consumption) causing inverter faults.
3) Solar sizing will lartgely depend on refer power requirements. Refer MAY be drawing more power from you two batteries than can be harvested by your solar.
Since you've already invested in the refer, I'd stick with it, and iron-out other problem areas to optimize your present system...My long distance guess is that you'll likely need more solar and more battery capacity for this new load.
Ok, I googled Solar Refrigeratiors and came up with a SunDanzer 4 cu ft upright with .7 cu ft freezer (Sundanzer.com)...I will assume this to be atypical of 'Solar' Refers...This refer though called a solar refer, is essentially a very efficient d.c. compressor type refrigerator.
Per their sizing chart, the power requirements can vary widely based on model and outside temperature.
Example for 4 cu/ft (w/freezer) at 90F: 720w p/day, and they recommend in the 'mid' 400w of solar.
Same example at 100F: 890w p/day and about 570w of solar.
If this is approx what your refer is, you'll need more batteries and solar.

I'm not sure why these things are sold as 'solar' refrigerators.. they're just another appliance.
I got the sales pitch on this at an RV store in LV.
I think because these units are so heavily insulated, they can then tout how little energy they use, hence, being 'run' by solar.
I think they're taking advantage of the common misconception that solar "runs" things. The only thing solar should be considered to be running is a battery charger.
Looks like THESE are the batteries (132 Ah) and THESE are the panels. FRIDGE link (don't know which though). Like others have mentioned 180W isn't going to do it. And now we know the battery capacity, 246 Ah isn't going to do it either.
EDIT: Updated fridge link with exact fridge.

mena , thank you so very, very , much for fixing my links, all of them
are super correct .
Fridge, the cheapest, freeze 55 , looks like cooler with
two very small compactors .
On another forum, I got this (again, I only would like to have hope still, I am not questioning anybody expertise, and appreciate
all inputs so much, anyway it goes like this :
The fridge consumes 60 watts. What is unknown is the on/off run cycle. If 100% the fridge uses 60 watts x 24 hours = 1440 watt hours per day. That would mean in your area 750 watt panel, 60 amp MPPT charge controller, and a 12 volt 600 AH battery just to run the fridge. You only have 300 watt pane, 20 amp PWM controller, and a 12 volt 240 AH battery. You are not even remotely close to what you need to have. .
Is it maybe possible use by fridge is not 24 hours , but significantly less ?
To the person, who advises sort to me to stick with the cooler,
sorry , do not have your screen name in front of my eyes,
please tell me what would be my necessary minimum upgrade,
I can fit only one more panel on the roof .
Can also someone help with inverter . This ones with smooth sinusoidal
wave are way to expensive, I can only buy same type like I have,
only better quality .
Can someone please go to link Fridge and look at Inverters and tell me which to buy .
If I will not be able to get any money back, what the most likely will be the case, and I will not buy fridge because is not possible to operate it, what is my best option to use this money,
additional battery or panel ?
I see I am asking for so much but I really need help,
and again appreciate all of it, I am receiving .
greetings eva

There is no way that fridge will have a 100% duty cycle unless it's sitting outside in the Mexican sun in July. I'd figure maybe 30%. That said, there should be some data on the site (I don't read Mexican) to tell you what you can expect.
As for the inverter, PSWs are likely in the $300 range. If that's too much, sorry.
