How would this compare to a YETI3000?

My brother is building a tiny home out of a 20ft container trailer and wants to be off-grid. He was considering a Yeti 3000 as a temporary solution to just run a fan, fridge, charge his cell and watch a few hours of tv along with a couple of lights but I noticed this and was going to tell him to consider this. I'm new at this and trying to work out the details on getting a solar system for my home but are these "solar generators" any good or a waste of money. I will admit, I do have a KYNG Power unit I use that I can use to charge up phones, run a fan, charge a laptop, etc. in case of emergencies. But it's only 500w with about 280wh

Here are the specs -

3KW solar power generator with 4.5 Kwh lithium battery

• Shelf-life: Charge every 3-6 months
• Management system: PWM charge controller, low battery protection
• Weight (Yeti & MPPT charger): 68.6 lbs (31.1 kg)
• Weight (cart only): 8.9 lbs (4 kg)
• Dimensions (Yeti only): 10.1 x 15.3 x 13.1 in (25.7 x 38.9 x 33.3 cm)
• Operating usage temp. 32-104 F (0-40 C)
• Warranty 24 months

for a quasi permanent install I could not recommend a yeti style equipment due to cost. I think in his case an all in one growatt would be perfect for his application. Some pannels on the roof an single box to mount. You could run a generator to it if you had to in dark times but otherwise its just about as plug and play at a fraction of the cost.

Thanks.

He likes the portability of a yeti style solar system. Because of this, which of the two would you suggest is the better deal?

You haven't included cost, so I assume this isn't part of the equation. In that case, I would choose the Yeti because:

1. Known company, known product quality, reasonable warranty
2. Specs above say PWM SCC, but product page says MPPT - I presume they have upgraded their product.
3. Worse max power input at 600W max, but will you need more than 600W charging? That's around 2,400Wh of charging per day.
4. Shit life-cycle, but spec'd at 1C discharge to 100%DoD so likely much better in 'normal' use.
5. Has PD ports so can charge/run laptops.
6. Expandable

I would 'trust' the Yeti more than some generic product.

But, as has been mentioned, would I buy this? No. You can just as easily get a fit-for-purpose off-grid system within a similar time-frame and at a far cheaper price. These products are designed for a very specific purpose - mobile power. I dare say this cargo container is not mobile.
