Someone disassembled one. It’s housing standard lithium ion pouch cells. Definitely not solid state

[boblatkey]

Super important to differentiate between power and energy. So that unit produces 4000 W of continuous power, and it has an energy storage capacity of 2600 W-hours. Or 2.6 kWh. people get their units screwed up all the time and it just confuses everyone.

[mikebrant]

I just saw other videos and while your answer was 100% correct, I now understand better. Good job, as always.

[starvet]

Great video! I purchased that unit last year and has not failed me. I use it to plug my Rv refrigerator when traveling. Keeps me from having to turn on the propane or turn it off when going through tunnels. I prefer to travel with my propane off. I now have two units one inside the Rv and one at home.

[paulschimel]

Wow that is super neat, but at $3000 it would have to come down a bit. For about $500 you can get 2 100
Ah li time batteries and $400 for an inverter I’ll save the $2000 and deal with the extra size.

[invaderjoshua]

I really just want a 99.5wh-100wh (TSA okay) version of this, with a 40w-60w backpack compatible waterproof solar panel for it. The safe operating temperature range being greater on solid state batteries would be a game changer for thru hikers during winter and winter camping / mountaineering.

Output: 4000 Watts Continuous Use (with up to 6000W momentary surge)
Capacity: 2611 Wh (54Ah @ 48V) Question so at 4000 watts this would last about 35-40 minutes???? Back up battery needed for sure. I really like the concept but price and storage is an issue.

60v limit on solar input is a dealbreaker. These units should be able to take a string of at least 3x residential panels, and have a max input voltage of at least 150v. That anemic 60v, 10amp limit, means a single residential panel. Yes, you could Y to 3 panels in parallel, to overpanel, but you'll always be excessively restricted by it's input limits.

At most, this is a battery pack with an inverter/charger. It's not any kind of option for solar use. PASS

[GymWithRay]

Do you know where to buy the add on expansion batteries?

[willieiso]

did it turn your transfer switch on? some power stations spool up the power, so the transfer switch does not see 30 amp... wondering how this did?

[michaeld]

I saw minute man prep on YouTube at CES and told them to fix MPPT to 2000watts.... Then this is a winner.... So i run mini split on garage on a 2000watt inverter power station... Is draws in summer Phoenix heat 900-1200 watts i have 1100watts coming in during day so it keeps up with it.... At night i use EG4 48v to charge on one of the dual mppt and it dies about 3 hrs at night... Battery is still half charged.... But it can only inlut 550 watts but load is 1000 watts so i need to add 2nd battery on othe mppt so it will get the full capacity.... So this yoshino is only 600watts so it will suffer if only solar is charging during the day and load is say 1000watts at end of the day it will not even be fully charged for Like the inverter and power density... Redesign mppt and you will capture the market 😅

[Sirrichz]

On some of the output test you clearly got the unit over 4000w but im curious to see how long it will run a 4000w load i noticed you can get some units to their peak out or even just close to it ..but they can only do it for 3 to 6 mins

[jamescabaniss]

Excellent review. You might have stated it but I missed it, for those that are interested Yoshino claims 4000 life cycles to 80%, not bad. So if it is as safe as LFP, we might have something here due to it's higher energy density chemistry.

[arthurcutting]

I'm waiting for Mr. Fusion to come out so I can power my flying RV with table scraps and flat soda.😊

[mikedonovan]

The price per watt hour (2600 total) on this unit is not competitive in the marketplace; 3600 watt/hr Delta Ecoflow Pro is $1000 less on Amazon.

[RamblinRoadies]

I have two Marxon units with total 2880Wh/3600W with a 30amp outlet that I paid about $1200 for. They're going to have to get more competitive with their pricing.

[geraldhenrickson]

Thanks Brian. Nice video, great looking portable power supply with solar charging.

[gregory]

I would only add, this is a first generation power station. I suspect these units will get increasingly better as the price point drops. Also, solid state is safer and more dense at the same time. This might be the future of emergency solar gens. I'm actually stunned they got solid state out like this.

[bobwallis]

why is there a problem with the term solar generator?

[RobertZullo]

Great review Brian! Definitely a first on many fronts here. Solar charging (10a) is a bit limited for my liking but still an impressive unit.
