Charge A Maxoak Bluetti Power Station/Solar Generator With Solar Panels
Maxoak is a relatively new company that makes power stations, also known as solar generators. They’ve impressed a lot of power station fanatics, myself included, with their product lineup and powerful features.

In today’s post, I am going to help you find solar panels that are compatible with the Maxoak Bluetti power stations. Since Maxoak has a couple of different options with different inputs and wattage ratings, let’s put them all on the table first and list their specifications.
Note: Scroll left/right on small screens to view all products in the table.
Solar Panels Compatible With Maxoak Bluetti Solar Generators
Finding a solar panel compatible with the Maxoak Bluetti power stations/solar generators is going to be very easy due to their impressive input voltage ratings.
We’re even going to be able to connect solar panels in series which isn’t something you can say about every power station.

Maxoak includes MC4 adapters with all models except for one, the 200Wh. They sell the MC4 adapter separately, and you can find it here (click to view on Amazon).
Now, let’s take a look at a couple of solar panels that are compatible with all of the Maxoak Bluetti power stations above.
Note: Scroll left/right on small screens to view all products in the table.
The limiting factor with the Bluetti power stations isn’t the input voltage, but the max amperage. The smallest 200Wh model has a 5A maximum input, and the rest has a 10A maximum amperage input. So to max out the amount of solar the larger batteries can handle, you should connect two panels in series. More about that down below.
Solar Panel Recommendations
If you have the Maxoak Bluetti 200Wh, any of the panels above work but I wouldn’t bother combining two or more.
For the 400Wh and 500Wh, I would connect two Renogy 100W in series. Otherwise, any of the panels on the table will work great.

For the largest EB150 and EB240, any panel works, but two Richsolar 190W or the Renogy 160W solid/flexible panels wired in series would be my choice.
In general, I will always recommend more panels for a quicker charge, but it depends on what you have space for. Remember the 10A limit and make sure you don’t go above the voltage rating when connecting panels in series.
Now, let’s talk about how you can connect two or more panels.
Connect/Combine Two Or More Panels
So we know the max amount of watts, volts, and amps the Maxoak Bluetti power stations can handle. How do we utilize it to get as close as possible to the maximum input?
First off, the Maxoak Bluetti 200Wh has a 65W maximum input, so I wouldn’t connect more than one 100W/160W panel to it.
Most of the time when it comes to charging solar generators with solar panels, you need to connect two or more solar panels in parallel, to increase the amperage while keeping the voltage the same. This is because most power stations have a maximum input voltage between 22-30. As seen in the table above, every Maxoak Bluetti power station can handle at least 40V, which is unusual.
So what is the voltage of a panel and which voltage matters? Renogy recommends looking at the open-circuit voltage, while it’s more common to look at the optimum operating voltage.

A 100W panel’s VOC rating is usually around 22V, with a VMP rating around 18V. If we follow Renogy’s recommendation, you shouldn’t connect two 100W panels in series to a 40V charge controller, but I know a lot of people that do since they look at the VMP.
A series connection means that you connect the positive wire from one panel to the negative wire on the second panel, then take the positive from the second panel, and the negative from the first panel, and connect those to the MC4 adapter included with the Bluetti power stations.
Connecting solar panels in series doesn’t require any additional adapters/Y branches.
If you want to connect two panels in parallel to double the amperage but keep the voltage the same, you’ll use a pair of MC4 Y branches. Connect the two positive wires from each panel to one of the adapters, then do the same thing for the negative wires. Lastly, connect the MC4 Y Branch to the MC4 to DC adapter included with the Maxoak Bluetti.
To connect four 100W panels, we can use both parallel and series. Split them up in two, then connect two in parallel with an MC4 Y Branch like this (click to view on Amazon). You’d need two pairs of these for the setup. You’ll basically turn four panels into two large ones.
Then connect the two pairs to each other in series, and you’ll double both the amperage and the voltage, and come close to the maximum amount of input watts the MPPT charge controller can handle.
I put the open-circuit voltage of each panel (except the Suaoki) in the first table, so you can easily calculate how many solar panels wired in series your Maxoak Bluetti power station can handle.
Let’s look at a couple of examples following Renogy’s recommendation. Starting with the Renogy 100W that has a 21.6V VOC rating. Connecting two in series equals 43.2V, which is only compatible with the two largest Maxoak Bluetti power stations. Three panels equal 64.8V, so only the largest EB240 would be compatible.

In that case, if you have the Bluetti 200Wh, 400Wh, or 500Wh, it makes more sense to do a parallel connection.
Two Richsolar 190W wired in series would output 48.6V at most, and three 72.9V. Again, this is if we base it on the VOC, not the VMP. Most look at the VMP since that’s the highest voltage the panels output under load.

Frequently Asked Questions
How Long Will It Take To Charge With Solar?
If you know how many watt-hours the battery in the power station can hold and the wattage your panels are generating, you can quickly get a rough number by dividing the two. For example, 500Wh/120W=4.17 hours.
How Can I Improve The Charging Efficiency When Using Solar Panels?
The easiest thing you can do is tilt the solar panel towards the sun. If the panel faces the sun, it will do a much better job and generate as much electricity it possibly can.
Another thing you should do is make sure the panel isn’t shaded, not even a little bit. Sometimes a tiny bit of shade can bring down the charging efficiency significantly.
Which Maxoak Bluetti Is The Best?
That’s a question that deserves its own post, but for a quick answer, I would say that it depends on what you need. Write down the electronics you need to power/charge, and for how long each day.
Figure out how many watt-hours you need per day, and if you plan on using solar panels, how much will the solar panels generate on a good day? There will be cloudy days, so will you have enough power to charge your devices even if there are a couple of cloudy days in a row?
That said, I really like the Maxoak Bluetti EB150 and EB240 because they have a lot of great features that make them stick out when compared to similar power stations.
You could plug a camper into either of them with a 15A to 30A adapter (or the 15A to 50A if your camper is 50A), and it would power everything in it except for the microwave and air conditioner.

bought a bluetti 1000w 2400wh , come with 2 200w newpowa panels, told to hook them together, only get 40-50w, great sun, great angle….any ideas or do I need different panels ..ty
They should work and perform better than that. Have you tried connecting one at a time, do they make 20-25W each then? Are they connected in series or in parallel with an MC4 Y branch?
If the battery is near a full charge, it will charge slower, which could also be what’s happening.
could you just use one 200w 24v panel?
Absolutely, as long as the open-circuit voltage is below what the manual for your specific power station says.
I bought the Bluetti 240 along with two 200 Bluetti solar panels. I want to add a 3rd 200 panel but not sure if the input max voltage of 65 can handle that as 3 panels total 72 volts. But the ad recommends at least two 200 panels. Makes it sound like 3 panels is possible??? If not possible, is it ok to add a different 200 panel that is only 18 volts?
It’s likely that three panels will work with the EB2400 since the VMP voltage of a Bluetti 200W panel is 20V. Maxoak says to stay below 68V (VOC) though, but based on my experience it’s fine as long as the VMP is below the limit during load. I suggest contacting Maxoak to make sure it won’t hurt anything, then order the third panel from a store that allows free returns in case it ends up not working.
Yes, you could also try a panel with a lower voltage but then you might throttle your other panels depending on the amperage of the third panel.
Thanks Jesse, I believe you are right, and I am sending an email to Bluetti Kayomaxtar service department which was included in the EB 240 manual. It states in different acronyms that the input specs are: PVInput Voltage Range are 16-60Vdc(OVP 73V+/-2V). That would cover the panel VOC spec of 24 x 3 for a total of 72 volts. I will let you know their reply.
I have two 100w Zamp Solar panels. One is regulated the other is non-regulated. Are these compatible to a Bluetti 716wh Power Station? Are there adapters for connecting these? Thank you.
They’re most likely compatible, but I have heard that the polarity of Zamp’s panels are usually the opposite of everybody else’s. I’d check it with a multimeter before buying any adapters though.
You would have to bypass the charge controller on the second panel before wiring it in parallel with your first panel.
To help you further, I’d need to know what type of connector your Zamp panel uses. If you think you could bypass the charge controller on the second panel, I can help you find a way to wire them together.
Is the BALDR 120w solar panel compatible with the Bluetti 537wh? I can’t get it to charge with the panel? Any suggestions?
How are you connecting it? Did the solar panel come with an XT60 adapter? Otherwise I would try to connect the panel to the Bluetti with an 8mm female to XT60 adapter.
I think I’m confusing myself after reading about solar panels and generators for 4 hours tonight. This is what I’m considering MaxOak EB150 with Renogy 100w panels you recommend. I had already picked these renogy panels weeks ago, but just could not decide on the generator.
So I could do 4 parallel or 2 parallel with 2 series. The second option being the biggest output for charging the EB150. I do not need any special wiring, or heavier gauge other than the regular MC4 Y branch as suggested? Am I overlooking something I have missed?
Thank you so much for helping this girl out.
Hi Gin, sorry about the late reply.
Yes, the best setup for you would be a series-parallel circuit. With four Renogy 100W panels you should end up with 50V @ 11A, which is safe for the EB150.
Correct, I don’t know the gauge of the MC4 to DC adapter included with the EB150 but it should be at least 14 AWG.
Good day, Jesse!
I have a bluetti ac30 with 300watts.
My solar panel is from Renogy.
It’s only 100 watts.
Is this enough to charge my solar generator?
Please reply. Thank you!
Yes it’s enough, all you need is an Mc4 to 8mm adapter (click to view on Amazon). A single 100W panel should fully charge your AC30 in around 4-5 hours.
Did not find your post until tonight. Been on computer all day. Wished I had found you weeks ago.
Have Bluetti EB240 w/2 PV120 panels. Wanted stationary panels & faster charge time. Need power for fridge to keep insulin for son and myself if grid goes down.
Contacted BougeRV about “2 – 200W 9BB panel working for EB240”. Reply was “2pcs of 200w solar panels can be connected in series and the current will be limited to 10A due to the battery” Specs-Open current voltage VOC- 21.62+3%V, Max Power volt VMP17.98+3%V, Short Current circuit Isc 12.09+3%A. What does it mean current being limited to 10A.
Will these 2 panels in series work or am I going to blow up my unit, shorten life &/or loose way to much watts, need special cables/wires, or anything else.
Been trying by phone, text and email since May for Bluetti-forget reaching them.
Can you please help me? Any suggestions would be appreciated. Thank you
Yes, they will work in series with the EB240 and it won’t damage the Bluetti. That’s a great choice and setup.
In ideal conditions they’ll be outputting around 36 volts at 12A. The charge controller will limit the amperage to 10A, but that’s fine. As long as you don’t exceed 68V (you’re at 36V with two 200W 12V panels), you’re good.
Just wire the panels in series and connect them to the EB240 with the included MC4 to 8mm adapter.
You are the best!!! I have been trying for days to figure this out &/or get someone to help me. YOU ARE THE ONLY ONE THAT RESPONDED. Thank you so much. I owe you big time.
One other questions – wires
The MC4 adapter I received with EB240 is not what they showed(cheap). Super thin wire going to MC connectors that is exposed for 4″. I ordered SolarEnz adapter-12awg (highest gauge I could find). Will have to run 50′ extension wire from panels to unit inside house. What do you recommend – 10AWG or 12AWG and what seller. Since COVID seems to be a lot of dissatisfied wire customers over awg of what they receive. At this point don’t want loss of input due to wire gauge. Not worth trying to save a few bucks.
Thank you again.
Happy to help!
For 50′ I would actually get 8 AWG. I have used the Windynation MC4 extension cables for years now and they have a 50 feet 8 AWG cable version (click to view on Amazon).
Hope it’ll work out with the SolarEnz adapter, I’ve heard of some having to shave a little bit of plastic off to fit the Bluetti input. I haven’t had to do that with my Bluetti but you should be aware of it.
Thank you again – wish more people were as caring as you are.
Just realized I didn’t send it. yesterday-thanks
Forgot by being in a hurry. Is there a better adapter than SolerEnz out there?
There are a bunch of similar ones on the market nowadays but I haven’t tested any of them. Seems like it’s hit or miss when you buy any of these adapters, sometimes one will be wired wrong or the wire will be a different gauge than advertised. I might buy a bunch of different ones and do a test in the future.
thank you – will do
I have two BLUETTI Portable Power Station EB3A, 268Wh and a BLUETTI PV200 Solar Panel | 200W. I also have a DOKIO 110W 18V Portable Foldable Solar Panel Kit. I received a MAXOAK Generator Portable Power Station 200Wh Lithium Emergency Battery Backup Pure Sinewave 110V as a gift and it says it needs the 60Watt panel. Can I charge it, the 200Wh, with the EB3A or one of my current solar panels? If so, how would I hook it up? (I really don’t want to spend a $100 just to charge it with solar). Thank you.
The Maxoak 200Wh should be able to charge with the Dokio 110W panel if it’s the panel that came with several DC connectors. Do not use charge controller included with the Dokio panel.
Connect the SAE cable from the panel to the included SAE to XT60 adapter, then the XT60 to DC adapter (one small plug), lastly connect the largest of the included DC plugs which is the 8mm connector, and connect it to the power station.
Let me know if you’re having trouble.
I was usingi 2 Bluetti sp 120s to charge my MaxOak 150 and they stopped charging it. The wall charger works so would it be the panels don’t work?
What would make the panels stop working?
Have you tried connecting just one of the panels? Are they connected in series or parallel? Could be a faulty MC4 to 8mm adapter as well, sometimes the MC4 connectors come loose.
Thanks for your quick reply! It’s odd when I first plug into the MaxOak the charging light turns on and lights up the panel. Once sun hits the Bluetti everything shuts off. I did try just one of the panels. But is still doesn’t charge. They were hooked up in series. I will check the connectors.
It was the MC4 cable. Thanks so much!
Glad you found the problem!
