Converting My 2014 'EU T@B 320' to Solar Power - Is a Bluetti 1000W Enough

KasperKorea

I recently bought a 2014 EU-version T@B 320, built by the original T&B manufacturer Knaus Tabbert. It’s incredibly solid and still looks almost new, but it’s a fairly barebones model. There's no A/C, fan, toilet, or Alde systems.

It has the original 3-way fridge, lights (all still working), and a Truma heater. I’d like to reserve the propane canister for heating and run everything else on electricity. The original battery still holds a charge, but since I mostly camp off-grid, I’m thinking of switching to a lithium setup.

My plan is to use a Bluetti 1000W power station with the complimentary bluetti solar panels to run the fridge, lights, microwave, dehumidifier, and a MaxxAir fan (I'll have to install this). I’ve given up on adding an air conditioner since I want to avoid cutting into the trailer’s shell. Hopefully the MaxxAir fan together with a dehumidifier will keep the space livable even in summer.

If this setup works well, I’d like to remove the original battery altogether to gain more storage space under the benches.

• Has anyone done a similar conversion or know a good source to learn more about it?
  
  
• Would a 1000W Bluetti be enough for a 2-day trip, or should I consider a larger unit to handle cloudy days?
  
  
• What are the pros/cons of using portable Bluetti solar panels that are not mounted to the roof, versus fixed roof-mounted solar panels? - I'm leaning to portable solar panels, since I can place them anywhere for maximum efficiency.

If you are going to change to a lithium battery anyway, you can get a larger (more amps) battery than the 1000 watt Bluetti system which is only 83 A.  You can still use portable suitcase solar panels.  If you run the frig on propane your battery will last longer, as the frig on DC will quickly drain your battery.

I agree with @Sharon_is_SAM.  
At 12V, the Bluetti will provide only 83 amps of capacity.  My 2-way fridge is the largest draw on the system and gobbles up about 36 watts for every hour it runs.  I you assume that your fridge will be 'cooling' about 25% of the time (cycles on and off), this would give you only about 10 hours of run time without any solar recovery.  
I have 200 Amp Hours of battery capacity and about 300 watts of solar capacity.  With average sun, my batteries last almost indefinitely while boondocking.  
Regarding the solar panels, I love my rooftop panel because they charge while I am driving, but tend to get more return from my portable, suitcase panels because I can move them around to optimize the sunshine. 
My guess is your Bluetti would be fine for 2 days, provided (as stated above) you operate the fridge on propane.
