The Professor reviews the solar / battery powered Ecoflow Wave 2 portable DC heat pump that does both air conditioning (a/c) and heating via solar panels or 12v – 60v battery bank. It’s also IPX4 water resistant!
WATCH IT HERE
CHANGES:
-
updates from original wave
-
bump from 4000 to 5100 BTU, of course this new model also heats at 6100 BTU
-
much quieter (old one was 63db on low fan eco mode, 66db on max)
-
longer running 1159wh 8 hour battery vs 1008wh 6 hour battery. New battery also offers a USB QC port and a 100w USB-C PD output.
-
vastly upgraded solar support. It now charges from 11-60v up to 400w (also means you can charge it with ANY 12/24/36/48v battery. I will demo this in a future video)
-
they replaced the silly dial with proper up/down temperature buttons that can’t be accidentally bumped
-
larger much improved display screen that’s much more intuitive
-
removable / cleanable filters
-
IPX4 rated (original Wave had no water resistance)
-
-
“unboxing” (what it comes with)
-
Size & weight: 20x12x13 inches at 32lbs unit + 17lbs battery (original Wave unit was 6lbs heavier)
-
Temperature range setting goes from 60F to 86F
TESTS:
-
I did do a full firmware update before starting any testing so it’s the latest version as of 5/12/23
-
Will it run directly off solar? (no battery)
-
Prove 8 hour battery claim
-
11-60v 13A 400w testing
-
Show the remote app
-
There are 4 lights …
OPINIONS:
-
Let’s start with the Debbie downers. First, you can’t charge the battery without main unit and you can’t charge it “battery to battery” from another Ecoflow product. You’re forced to charge it either via AC power or the XT60 solar input while it is connected to the main unit. Using that input you can however charge the internal battery with an external 12/24/36/48v battery.
-
Hose coming out of the top is a weird design choice. Going by the documentation it seems to be for easier sideways mounting in a window assuming you are placing the output hoses horizontal instead of vertical like I have.
-
Ecoflow does offer a 1 year warranty on this product but I’m disappointed they didn’t offer a longer warranty competitive with their solar generator lineup.
-
Besides those few quirks I absolutely love this thing. I like it so much I’m considering building a shelf on the wall next to the window and mounting it permanently at least until I can get a mini split installed in this room. I ended up burning huge electricity over the winter by running an electric radiator heater, and the Wave 2 would be far more efficient – especially seeing that soon my property will be going off the grid.
-
By biggest likes are the fact that it can now be recharged with enough solar to keep it running 100% for free as long as you have 400w of solar coming in, and the fact you can use virtually any solar panel you want. You can also charge it with 48v external batteries now which is epic.
-
It’s also whisper quiet on eco mode and not that bad on max mode. It does fast heating and cooling and switching between the two and setting the temperature can be done remotely via app anywhere in the world – and you can even see the room ambient temperature which is great if you’re using it to keep your pets comfortable in a vehicle or RV.
PRICING:
-
Now this is Ecoflow and they love to innovate, but that also means the Wave 2 doesn’t come cheap. The bare unit without battery retails for $1099 and with battery goes for $1899 (before 8% off code). Now before the armchair warriors start posting about how they can actually buy an off brand 1 ton mini split for this kind of money, don’t forget a few very important facts. This one is truly portable, requires no special installation or vacuum equipment, and can run entirely off solar. You can take it with you camping, use it in your vehicle RV or tent, and then bring it home to use in your shed or spare room. Since it has it’s own battery you can cool or heat any small area quickly and with very little power. You can take this compact unit along with its own battery and a 400w solar panel for a truly portable HVAC system that’s mini split efficient. Since it’s remote app controlled you don’t even need to get out of bed to turn it on or off.
-
Those of you with the Ecoflow Delta Pro, Delta 2, or Delta Max (or their external batteries) can plug directly into the Wave 2 for super extended run times. Of course those units take tons of solar so you can easily run indefinitely off the grid at virtually no cost.
-
This makes the Wave 2 extremely versatile and that’s what you’re paying a premium for. If the warriors still feel like leaving a comment saying they can buy an air conditioner at Walmart for $99 feel free, but you’re totally missing the point.
