Got a new fridge installed yesterday. Only thing left is a little insulation and a trim piece.
Removal and install was really easy. No, I'm not going to post a video...there are enough of those boring things out there amongst the interwebs as it is. Here are some pics of the...
I think the installer and I need to have a serious discussion about his calculations and assumptions. I haven't yet, but I'm going to send this page to him. It's very informational, thank you all!
I just went to Home Depot and bought a residential fridge. It gets delivered on Fri so after...
DM2862RFB Mfg date: 2018 1500 BTU/Hr (440w)
It runs for 3,000 hrs a day, culminating in 9 trillion Megawatts/12hrs or the equivalent of North America.... Anyone interested in a slightly used fridge?? :sneaky:
Well, I thought of that option also, but I'm not sure I want to be subjected to empty propane bottles when trying to keep my food cold. Theoretically, yes, I can find a location to refill bottles, but why, then, did I spend the money to install this rather expensive solar system?! If I can...
I just read your post to my wife and commented that before we moved into the camper, we too had an LG fridge with a linear compressor. We bought it used and had it until we moved out. She said "that makes sense because our electric bill went down after we got the new fridge." Way to go LG. I...
Good Gawd from Bloomfield!? If you wanted to pick a fight, couldn't you have just dropped some Mom jokes or something?? :ROFLMAO:
I understand what you're both saying about the legacy 12v system, it's just so clunky! I hate clunk! :rolleyes:
My next step is getting the new fridge installed...
I was serious about my cousin. He's the Electrical superintendent for a major plastics manufacturing company here on the coast. He really does have or have access to a pretty awesome array of electrical tools. He's just not familiar with solar. (plus he deals with 24K hp electric motors and...
That's the kind of real world data I appreciate. Thanks for the info.
After thinking about it for a bit this weekend while getting my new fridge installed, I'm going to leave the 12v system installed while testing the draw of my new fridge (I'm really excited about it!!). I'm probably going...
I did watch a maintenance video about cleaning the back of the fridge and how important it is. It's a moot point now as I've already swapped the old Dometic for a new residential LG. The back of the Dometic wasn't grimey, but it was dusty. And I learned that the embarrassingly undersized...
This is how I understand the connection:
Solar panels and/or shore pwr connect to EG4, EG4 connected to 48v batts and breaker panel, breaker panel distributes 120v to outlets (A/C, microwave, fridge, water heater [when on] etc.) and also distributes 120v to original 12v ac2dc converter which is...
Now that's an idea I haven't thought of before. I have got the real estate upstairs for a couple more panels. The camper even has a port for a panel to charge the battery. I suppose I could pick up a panel at Harbor Freight. I'll look into that option as well. Thanks!
I'm picking up the new fridge today. I'll get the Dometic removed and the LG installed over the weekend, weather permitting. (I'm surprised at how much it ACTUALLY rains in S Texas?! Everyone says they're in a drought, but we either brought the weather with us from Idaho, or Texans don't know...
Thanks for the suggestion.
I bought this one: https://www.homedepot.com/p/LG-Electronics-24-in-W-11-cu-ft-Top-Freezer-Refrigerator-with-Door-Cooling-in-Platinum-Silver-Counter-Depth-LTNC11131V/308085233
We had an LG with a linear compressor at our house before we sold and moved into the RV...
I appreciate directness and your candid comments. My initial response is that I want to send him this page. However, I certainly don't want to burn any bridges and hopefully, I can relay some of this information to him so that we can negotiate a favorable outcome for both of us.
Thank you...
But you have 3kW of AZ high desert PV and 23.3kWh of battery?! 75% of your system is still way more than 100% of mine. ...which I will never achieve...
Ha! Thanks!!
I think I'll do some amperage draw testing for my dc appliances to see what will work. Shouldn't be too hard. My cousin has AN AWESOME set of tools!!! (Fast times at Ridgemont High reference, there.....for all of you youngsters...)
It's still hooked up to 12v, but only the circuit board is running on 12v. It senses if there is 120v and toggles between propane and ac when the unit is "on". If I turn off the 48v inverter, the fridge will just switch over to propane since it doesn't sense the 120v coming in anymore.
I'm...
My wife and I now live fulltime in our 34' fifth wheel. We are currently in TX. In October, we went to Hawaii for a month and while we were there, I contracted with a company in Idaho to install a solar system. I now have 18 - 100w panels, a 6000w inverter/charge controller, 2 100ah/ 48v...
Yes, Modal.
Two settings: AC or gas. There are two buttons on the front panel. One is the pwr button (on/off) and the other is "Auto" which toggles the setting from AC to gas. When "Auto" is on, the fridge seems to recognize if 120 pwr is coming in so it enables that function. If I turn...
Isn't that what RoadTurtle is asking? I think he's right. The 12v inverter is receiving 120v from the new 48v inverter and batteries via the breaker/fuse panel as if the rig is hooked up to shore power. So I see his description of a "Loop" but it's just a charging loop to power the 12v system...
I"m sure it's running on electric only. And I read this article https://www.beginningfromthismorning.com/refrigerator/ suggesting that you are right about it burning tons of energy. My installer, though, is sure that it's supposed to be more efficient. We're trying to exhaust all possible...
Well, we've tested that before (this has been a months long process) and we determined that its only pulling 30 - 50?! But, even if it IS pulling 100, should the fridge be continuously pulling 350 - 450 all day long??
This is what I'm thinking too! The conversion is getting me! Do you think it would be wiser to do away with the original 12v battery and inverter and install a DC to DC converter to power the 12v system in the camper?
Very close. Modifications were made:
It's a 50amp rated service but one leg of the connection has been disconnected so it can only bring 120v into the EG4 (not a 240v model). The 50amp breaker is a combined breaker. there are two separate breakers connected by a tab.
The rig has 2 A/C...
Well, crud!
What would your suggestion be to rectify this situation? I've asked the installer about buying a new fridge. I've asked about installing another battery for more capacity. I've asked about eliminating the 12v battery system. I'm not sure what other direction to turn.
I have both. The trailer has the original 12v inverter and battery and then a 48v system was installed "around" it. The installer left the 12v in place then connected the 48v to the breaker panel to just leave as much of the original system in tact.
Yep, that's what I"m trying to uncover here from people who have more experience than I about what ought to be installed/removed/upgraded to make this a stand alone system that will allow me to operate my camper appliances efficiently. We've always planned to "follow the weather" but realize...
I don't have that number. My installer says it's negligible. And I've seen low single digits into the low double digits depending on the time of day or night. I'd have to test or ask to get you that number. Sorry.
Ha! That's my kind of sense of humor, however, since I'm trying to fix my rather expensive solar system, I decided to keep it bottled up for the time being.
No, no diagram. Without unpacking my basement, removing a wall (moveable wall) and getting behind the breaker panel, I can't see what...
This is how I understand the connection:
Solar panels and/or shore pwr connect to EG4, EG4 connected to 48v batts and breaker panel, breaker panel distributes 120v to outlets (A/C, microwave, fridge, water heater [when on] etc.) and also distributes 120v to original 12v ac2dc converter which is...
Well yes, that's my position too. But my installer and leggo my @sunshine_eggo make a reasonable argument for leaving the 12v legacy system in tact. Instead of removing that in exchange for a dc2dc converter, the 12v converter and 12v battery act as a buffer against slide and jack power surges...
He said that he's waiting for some parts and that he'll build a plug-and-play DC2DC converter for me to install so I can remove the old 12 v system. I'm fine with installing that myself, and if that fixes the unusually large draw, I can live with it. However, if it makes more sense to remove...
Ha! I got all the kids off the payroll last spring! It's just me and my wife, now. And she's as paranoid, if not more so, than I am about saving and being efficient! If anyone is not closing the door, I'm sure it's not her or me!! :ROFLMAO::ROFLMAO::ROFLMAO:
Those do look like a tank!!! But, if I were to purchase one, then it looks as though I'd have to buy an MPPT as well?? The one I have already has one integrated. It would have been nice to pass 240v on through though...
