Top Rated Midcap Portable Solar Generator Oupes Mega 2 Review 

It was this review that sealed the deal for me, I was shopping many systems. You tested the key usability features, not just max output. Thank you. ordered my mega 2. Now to figure out how many batteries I'll need...

Ben, you are the king on electricity and portable units. This is why I trust you so much.

A charge controller on the expansion packs? Man I like that.

Thanks for the review, this will be my next purchase

Thanks for sharing.

Wow, that Segway Portable PowerStation Cube Series sounds like a game-changer for outdoor enthusiasts like us! The massive capacity and fast recharging are definitely appealing. Plus, the waterproof technology is a great feature for those unexpected rainstorms. I'll definitely consider adding this to my outdoor gear collection. Thanks for the recommendation!

I like that the extra batteries have dc outputs on them. Something some of the big names do not have on their extra batteries. If you do not need ac power than you could just get the battery and have dc power.

I PLAN TO USE THIS WITH MY HAM/CB/GMRS/MURS RADIOS. THE 12 VOLT 30 AMP CONNECTION PLUS THE LIGHTER CONNECTION IS A MUST. NO ONE ELSE HAS THIS BENEFIT.

Thank you Ben. I had heard that the mega 2 30 amp plug had some limitations, but some of the reviews did not mention it and one did, so I was confused. I will primarily be using this RV. So I’m thinking that the mega three will be the way I will go your review is awesome thanks again

If the DPs had an additional 1600 watt solar input and their batteries were similar to these with the same solar input and outputs they would be hard to beat. I like the idea of split phase and getting 30A @ 240V

Bought one and using it like an ups in my server rack. Networking gear and servers are drawing between 600-700 watts. I should get about 2 - 2.5 hours of backup power. I also have rackmount ups’ between the mega 2 and gear. Backing up the backup.

THKS

Ooooh ah😮 no but really...👍 and thanks for getting in to it,great review

One critical factor I've discovered in my research on these devices vs. building my own system is that the customer has zero control over the quality of the parts used in the systems. These "budget" systems cost less for a reason. Quality is being sacrificed somewhere. While the AC inverter sounds impressive with 2400 watts rating with 5400 watts surge, the reality is, this is likely going to be the weak point, and the biggest reason your generator will fail. Why? Most of these portable generators do not use the more robust low frequency inverters with beefy transformers. These devices use high frequency inverters that are transformerless. These do not last as long and more prone to failure quicker when using heavy loads such as air conditioners, microwaves, cooktops and power tools. They will wear out faster. The warranty is 3 years and that's the confidence level this company has your device will last. Oupes is not alone. Many of the portables use high frequency inverters that can't handle power loads as well or for as long as transformer based ones. That said, I have no idea how long these will last. If you are a casual camper, it may last 10 years or more. I simply don't know. When you see reviewers do the FM radio interference test, they probably have no idea why they are doing it other than copying each other. But it is a quick, though not definitive test if your AC inverter is high frequency or not. Now, the advantage of high frequency inverters are they weigh much less, which is kind of important in a portable generator. They also take up less space. Oupes seems to have chosen good air flow and high noise to help reduce the strain on these cheaper inverters. Yes, the Mega 2 uses a high frequency inverter. I'm guessing pretty much any model below this, and likely even the Mega 3 and Mega 5 also use them. It's not just Oupes, I'm guessing most other brands also do. So, for campers, you are probably OK. RVers, you are probably OK unless the RV is your permanent home. Off Grid, light backup duty should be OK. Otherwise, permanent RVers and off grid homes should build with quality components that will last and that can be replaced without having to buy the entire all-in-one system.

This really looks good. But I am so invested in EcoFlow delta pro’s, EB’s and smart generators that I felt I should stay with EF. I purchased a delta 2 max w/ an extra battery and the new 800w alternator charger. Plan to get another extra battery before 50% government tariffs kick in.

You must have enough portable solar generators to power a small army! 😆 I’m more of an elitist. I only buy the best (Ecoflow, Bluetti, etc.) and don’t bother with anything else so its nice seeing videos of the smaller names that try to compete. Love the videos. Keep up the great work! 👍

This review made my decision, being able to add solar with just another battery is awesome. Makes it worth it. Normally I would have to get a whole new system to expand. I will probably get the Omega 3 though, need more AC. I wonder if it has true 30a connector?

I just purchased this unit and an extra battery 90% based on this video. Thank you. Where would I find a DC switch like you show?

Im sold.

What are your comments on fan noise per load? It’s seems a bit noisy on the fast wall charging

would be nice if OUPES would reval how many batteries oupes mega 2 can take.

pecron has solar charging on their expandable batteries too

Ben. Awesome review as usual. Are there limitations on the 30 amp plug on this mega 2 vs the mega 3? Want to use the mega 2 for powering my pop up trailer when dry camping. Of course I’d grab 1 or 2 expansion batteries. Thanks as always.

this thing looks sick to use in my fleetwood flair rv ! run the a/c for a few hours?

Carry as many batteries as you want, use one charge the rest and change them as you need them.

Can this be charged via 12V from a car while it is running? I would like to be able to charge it while I am on the road and unable to connect to the solar or AC power.

I see they still don’t have the right angle expansion cable that hugs the contour of the device instead of taking up a bunch of space.

Ben, are you able to buy the solar DC shutoff switch on your website? Or can they be purchased individually from Hysolis ?

Majoring in the minors, sorry, Recovering engineer turned teacher turned steam plant operator. * 2:48 determined the expansion battery cable on the left side but you never stood back and plugged it in. * Also, expansion cable jacks must be either/or as it is plugged into the lower jack; I would think that the complete unit, when stacked, would have best see the plug in the upper jack of the expansion battery going from upper deck to lower jack on the second battery. * Slow down 10% * A lot more work but some graphics on math would help 5:26 while a secondary feature of the expansion battery, you never explained that the car 12-volt car outlet could be used for a small AC inverter, or even a small DC refrigerator for a small cabin like mine. Not so minor is the fact that the Oupes website says the EPS is ≤20ms. You identified it as a problem, but you never checked the specs. I'm seriously considering this as a first foray into portable power up at my building. I have a 12 KW portable generator but also a 2200 Honda inverter generator. Everything has its place. Don't think I would trust this for a stand-alone walk away refrigerator. I could also take it up to power my home air handler should my home SMA system fail completely fail, 120V, 20A so barely.

Can you show step by step how to check wire polarity / voltage? We hear to "make sure" it's right or we can fry units but I don't know why how or basically anything. HELP I AM LOST!!😢

Will they come to Australia with 240 volts

My name is Derek, and I'm a solar generator junkie

If I didn't do the Oupes extension B2 to the Mega 2, could I connect a Bluetti AC180? For more WH and extend battery life? It's on sale right now for 569, instead of paying 1000+ for B2. Even tho B2 is 2048wh vs Bluetti 1152 wh.

Hi. Can you please assist me . I see there is a similar product this called Souop my question is , are they similar or not?

Other reviewers complained that the charge controller seemed to take several minutes to respond to changes in charging conditions being displayed on the screen. In other words, it seemed slow to calculate what was coming in. Did you experience that issue?

Just a heads up I’ve tried your solar sizing calculator and it won’t show me any matches. I tried on my phone and laptop.

Is there a minimum of solar it requires before actually charging it ?

Is this company from china too? Realizing a lot of these companies are fairly new and out of china. Warranties offered perhaps longer than the companies been in business. Can you cover some reputable u.s. based suppliers? Where they located, parts, what can they send you?

@ 4:37. I have to stop you right there. I have a question, which I've been wondering about with many reviewers, not just you Ben, but what I really would like to know is.......When a company, like Oupes sends you one of their products for review, *do you have to return the product after a couple of days once you have completed your review, or do you get to keep the product ?*

wheres the APP? we need to see these with the apps, not buying a product if the app is crap..

I like RU-vidrs that take the time to learn how to pronounce things before making a video. Every time a reviewer says Oops I immediately stop the video and move on

If you paid nothing then your opinion is worth as much as you paid! If you don't have any skin in the game I'll take my dogs opinion before I'd take yours! Seriously, look all over RU-vid you can't swing a dead cat without hitting someone reviewing this unit that they got 'free' making all of you a 'free': sales staff! I'm surprised and how little your reputation means to you, you sell yourself very, very cheaply! Oh, and with Oupes sending this to so many 'reviewers' this means your not as 'special' as you think you are...
