Not portable... But I bought the 6 pack of these in 2020 for $450, and have been running my tiny house off of them ever since. They're actually underrated. In perfect conditions I have touched 700w of input off 600w of rated panels.

Zero Complaints Whatsoever

These have MC4 cables, so the same ones as the provided solar charging cable on all ecoflows (MC4-XT60), so no modifications needed.

Lot of questions about solar here - definitely worth learning before you jump in. Go look at will prowse on YouTube, he's got an insane amount of really great content. Here's a link to a beginner diy setup.

I'm just curious. What is the draw of these panels? I can buy used but fully functional 285W panels for ~$75. These seem crazy expensive.
Most of the solar batteries that people use these with can't take over 200w at a time. Both my bougerv 1100 wh unit and my blueletti 268wh unit can't take the larger output panels typically used for whole house setups.

I see the blueletti rated at 200W Max, VOC 12-28VDC/ 8.5A

Could/would the panels provide more voltage than this could handle?

Thanks for mentioning that. I am looking at expanding my boat solar and already have an inverter and charger so that's worth my investigating.

For others, there are variations with an inverter built in ( https://www.amazon.com/ECO-WORTHY...09FDD6HMJ/ ) or inverter and an AC-to-DC charger ( https://www.amazon.com/ECO-WORTHY...B089GGW2LB ) Note that those are not 12V.
Since the price is double for doing double function anyway, I think it's better and I'd prefer to get them separately.

Got any Controller alone that you like/recommend?

great price/watt, but man. idk why there are so many 12v panels out there now that mppt charge controllers are so affordable. id love to see some 200-300w higher voltage panels. they almost always make more sense.

These aren't the same as the Ecoflow panels. The Vmp is 20V rather than 17V so if you mix them on the same controller you will lose some output wattage.

Double/Triple: the savings is really in size/power efficiency/convenience. For a boat or trailer those are a big deal. They also tend to have a much better interface and control SW and closer to commercial technology.

I have not bought a 12V controller in a while but don't over research it: anything on Amazon for <$20 with 4.5 stars or better will be OK. I bet this is fine: https://www.amazon.com/Renogy-Wan...B07MVZ777D

This kind of thing would be better if it is damp: https://www.amazon.com/Allto-Sola...B09F697FBV

$75? How about $20: https://boston.craigslist.org/gbs...94555.html

Seriously, there are many options on Craigslist and Facebook Marketplace but of course YMMV. Here's 200W panels (near me) for $60 each: https://boston.craigslist.org/bmw...24256.html

These are usually removed from systems being upgraded and they seem more available during Spring/Summer/Fall.

I bought two of these going to a Renology 30A charge controller.. aside from dimensions, any different from this deal?

How do the HQST compare to the Renology ones?

This will prob be my stepping stone purchase into solar and only currently have a Bluetti and EcoFlow but would like to build out a system past just those two portable units.
Renology and HQST are the same company I believe

Can be effectively used to charge car battery for gate opener?
This would be overkill. A solar battery tender from Harbor Freight might be better.

Isn't the life of the $70 one half gone? Also don't solar panels lose efficiency over time? Doesn't seem like a great deal
