Great review on another option, thank you. Currently using the Bluetti (because of your review) for my RV ground deploy and it has been a solid choice.

Jason, I got this panel today and plugged it into my AC180 and it works fantastic. I just pointed it to the sun and without a real alignment, it was putting 390 watts into the Bluetti.

[@DM-fv7hw]

Nice review. I own the AllPowers currently but we are looking at setting up an EcoFlow Pro w/ extra battery for some house backup. I may add these to that kit. Can you add this panel to the 400w comparison spreadsheet? Thanks

[@teuton6167]

I have the EcoFlow 400 watt folding panels. The stand is useless, however I’ve learned that leaning one 400 watt panel against two aluminum outdoor chairs to support each panel works quite well.

[@Jasonoid]

I usually lean the EcoFlow 400w panel up against my fence or my shed. Two chairs would also work well!

[@kevinholland4156]

Looks like a good choice for my trailer. I would like to get the weight off the roof. It may be close to the 10 amps that my AC180 will accept, but I can always shade it a little. Good review Jason.

[@Jasonoid]

This panel should work well with the AC180. Glad you enjoyed the video :)

[@joynerrperez]

I tested an unusual setup with these where I left the two exterior panels folded and used it as a makeshift 200w panel (for those times when I'm tight on space). I was still pulling between 150w and 170w. Of course, you lose the kickstands at that point and have to be extra careful not to damage the panels that are on the underside, but I was glad to see this still worked. I'm trying to figure out if this usage would void the warranty, though. Otherwise I would have expected Renogy to promote/encourage this use case and so far I haven't found any source-- official or otherwise --suggesting to use it like this.

[@Jasonoid]

Well with the panels wired in parallel, I don't think it will do much damage. You should be fine to use it like that occasionally

[@Tom-Travels]

It has some FAB's (features, attributes and benefits), but unfortunately, my friend, at over $700 (incl tax) it is way to pricey for 400watts.

[@Jasonoid]

It's priced how all portable panels are priced. You pay a premium for portability. If you want cheap, go with a 400w glass rigid panel. You can buy those new on Facebook marketplace for around $150 right now.

I bought the Bluetti 420w due to your review, and i like it a lot. Renogi is better for temperature and weather apparently. But the Bluetti is solid choice.

The PV420 is a great solar panel as well. It puts out a little more power than this Renogy panel and folds up smaller. Each panel has their own benefits.

[@technik8838]

Interessant!

[@litnoregrets7551]

Seems like a good value. For me, since I camp with a car, this still folds a bit large for my needs. I parable need to go with 2x200w or some other multi panel configuration. Thanks.

[@Jasonoid]

Good choice for your setup. This is a bit large when folded so the two 200w panels would be a little smaller.

This my project using the Renogy 200w Felxible panels: kzbin.info/www/bejne/gnPInWeapcd-p9k They raised the prices a ton recently. They used to be priced near $300 each, now the price is very high per panel.

[@rcguymike]

EcoFlow has a new stand that is supposed to work with the 220 and 400W panels, i think it'll eventually be included with new panel purchases but currently is available separately

[@Jasonoid]

Glad to hear they have something new that helps with the panel sitting straight. That's excellent news!

[@anthonym5395]

Seems like a great design, I'd love to see other solar manufacturers going in this direction. Unfortunately the $ is a bit high - I like to buy ~$1/watt (ie. ALLPOWERS SP039 600W and others) not +$1.50. Will wait for the price to decrease otherwise looks promising!

[@Jasonoid]

It's a good change in technology for sure! I'd love to see more competition here as well!

[@mattp-ds6er]

Can you recommend an extension cable for that panel to the ac180 from renogy? I’m setting up an overland vehicle for the first time and will probably have a lot of questions regarding electrical needs. Is there a good book you can recommend for vehicle electronics? Also saw that you can ask a question to your new service but it would probably be a very long winded question.

[@Jasonoid]

Learning about solar takes time and the best way to learn is by watching videos about what you want to accomplish. Theres a large learning curve for sure and a bunch of new jargon. You can purchase a 12awg MC4 extension cable like this for a good price that will connect to the Renogy 400w panel and then into your AC180 solar cable: amzn.to/4belmBS

I have been wondering about these panels. They seem a lot like the topunive solar panel I found on amazon. I think the main difference is the topunive has a plastic frame and of course is 115 bifacial rated panel. It weighs about 6 pounds. I like that this one has an aluminum frame.

[@Jasonoid]

The aluminum frame is nice to have. It makes them much more rigid and less vulnerable to winds to blow them over.

[@johnnysweekends]

Awesome panel….!! Yea high pricing, but most of renogys products are actually pretty darn good. The smart batteries, the normal rigid panels, the little charge controllers that never die and the basic inverter 1000 or 3000 just last if not abused. But again there pricing is pretty high……but if it lasts 🤷🏼‍♂

[@user-vr2js1ml6w]

I wound up with 3 of these 400 watt panels. What Victron charge controller would you recommend for my 12v 480ah battery.

[@Jasonoid]

I'd recommend wiring your panels in series with this victron charge controller: amzn.to/4bLkepA The battery will be charging fairly quickly with lots of amps so it's an expensive charge controller. High amps equals more cost.

[@reginaldwalton]

I'm new to all this solar panel stuff and just got my Ecoflow DPU (with 2 batteries) and SHP2 connected. Still trying to learn all of this. I'm currently charting the DPU batteries via the grid off the SPH2, but want to add solar panels as an option. I know these would provide very little power to those batteries, but I don't want huge solar panels around and want something I can pick up and put back in the garage quickly. We have big hail storms here in Texas. Would these work to give me some charing power (maybe it would take a whole day or more), but just another alternative to the grid?

[@Jasonoid]

These are a great option for the DPU if you are looking for a durable portable panel. These are my new favorite option for a large format folding panel since they have the metal frames. They are super rigid. On the DPU, you'd connect these panels in series for the best performance.

[@reginaldwalton]

@@Jasonoid Thank you! Order being placed.

[@Jasonoid]

You'll enjoy them!

[@rthilson]

Would you run 2 of these in series in the pecron 2000 ? The Voc is close

[@Jasonoid]

That is close to the 95v cutoff. If hot weather the panels wouldn't be an issue. Voltage would be lower than spec. In cold weather it would be a problem. I guess it depends when you'd be using the panels during the year. Each solar port on the E2000 will take 600 watts, right? So if each 400w panel was producing 350 watts you'd be losing 100 watts of possible power if you had those connected together in one charging port. Why not connect 1 panel to each port and get 700 watts instead?

[@michiganexplorer7945]

I see it needs a solar controller if you are plugging into the solar on the side plug on campers.

[@Jasonoid]

Correct, it's just a solar panel.

[@mattp-ds6er]

Hi Jason, I was going to order this suitcase to charge a bluetti ac180 but renogy said it wasn’t compatible because it charges at 11 volts and the ac180 only accepts 10 volts. Is this true?

[@Jasonoid]

It sure is compatible with the AC180! You only have to worry about voltage when picking a solar panel for your power station. The voltage can't go over 60v with your AC180 and this panel is far from that.

[@celinetevlin775]

Are the kickstands really adjustable? They don't look it from the video. They really need to be height adjustable to allow you to tilt the panels more, rather than just moving the kickstands around from one fixed point.

[@Jasonoid]

Thank you for mentioning this. I think it would have been better to say the panel has folding kickstands instead of adjustable ones. They do offer a few degrees of motion but not much more than that.

The legs are not really adjustable what you see there is about it, you can adjust a couple of degrees but if you try to get it flatter then it just falls 100% flat, push them out too far and they will bend / break (the brackets that hold them on will fail we are being very gently with them) 2. The "protective" bag is just a fairly cheap material that will NOT protect the panel.. if you want that your going to have to make / buy something (until then use the box it comes in) 3. what you see there is a very clean one, ours came with black silastic all over in spots and many gluey finger prints. 4. there is no real way to hold it down other than the legs.. no holes nothing to peg down or tie down with etc.. consider that. [it would be well suited to a caravan / shack / emergency use in your house etc..] In all honesty if we had the choice again for any mobile use we would get a 300w folding one from bluetti or similar. If you want to use it in a less mobile application or you have the storage space then yes its a power house! can confirm very high output have seen 390W on it on cool bright days when first setting it up. it is around 10A.
