I'm using my watt meter to monitor the solar panel. It's actually interesting to watch the wattage reading. Gives me a good idea of how efficient my solar panels operating. Depending on the weather conditions obviously. We're getting into the rainy season here. A lot of overcast bright sky. But, my 200 watt solar panel is still putting out something 👍👍 a little 😎
I have a 60w solar panel for my camper trailer. With that I have a 200w battery. That is enough to run a refrigerator, a couple of lights, and to charge my phone and laptop. Solar power is amazing!
Hello from Urdaneta City, Pangasinan Province, Island of Luzon, Philippines. I'm retired here 6 years ago from Seacoast, New Hampshire. Also, an amateur radio operator for 30 years KB1DIG.
Thank you for the video. Interesting stuff. Not a lot of information on the MPPT device on CZcams.
I have recently posted some CZcams channel uploads on my solar panel setup for my ebike 4 wheel version. It's something like an anorexic electric golf cart hahaha.
Anyway, I ordered two of the watt meters. But, only using one. The reasoning. My solar MPPT boost controller solar charger is adjusted at a self setting of 66 volts. And, the watt meter is only rated for a maximum of 60 volts. I didn't know if the watt meter can handle the over voltage?? And, I don't want to sacrifice it finding out 😜 my luck I'd cook the watt meter hahaha
Nice to hear from you! Sounds like you have an interesting video and I'll have to watch it when I get back home! And i guess I will have to make a video where I am going to test what will happen if I run 67v through the watt meter! :)
These are amazing little boxes, I have 2 installed in my car to charge a couple of ebikes off the 12v from the vehicle, add 2 - 3m of 1.5mm thin wall otherwise it will pull too much current, you can regulate the current by cutting the length of cable feeding it. I have them both pulling 15 amps wired into the back of auxillary sockets, had to add internal cooling.
I have tried a couple of other MPPT boost chargers but this one is the best so far. I have ordered a 600 watt version from the same company and hopefully I will received it in a couple of days. I'll post a review of it as soon as possible!
@camillionmonkey I havent allowed it to over heat yet but im sure it would do if you allowed it to, it doesnt seem to be able to limit its current input at low voltages, I have seen it flash up 25 amps on the display for a few seconds then I've turned it off. Gets very hot above 15 amps without a fan.
Great video, thank you for doing the work for us.
Thank you and you are welcome. If you have any questions I will try to answer them here or i Will just make another video to show you.
I really think if your input voltage was lower, it would be less efficient. If the input voltage and the output voltage were closer in range, the MPPT will do less work, which should make it more efficient. MPPT is better at stepping down than stepping up.
Next week I will record two new videos. One where i am going to test this with a lower voltage input and one where I will test the bigger, 600w mppt boost charger from the same company. The bigger one will be tested with a 400 watt foldable solar panel from AllPowers.
Well dude, freaking AWESOME test and actually I'm going to do it the same exact way to charge my ebike from a cheap 100w panel. Cheers from USA!
Glad to hear it. Would love to hear how it worked out for you! Cheers from Sweden!
@@ollelund I've set mine up and its working. I'm boosting from 18v up to 56v so perhaps the efficiency would be less than on your experiment? I'll get you know by Saturday when it's sunny
@@mattc825 how is it going??
@@ollelund It WORKS! I can get about 1.3 amps under full sun @ 55v and charge this ebike battery perfectly. So yeah it seems the efficiency is a bit lower when I'm boosting from 18 all the way to 55v but still pretty thrilled
Great video, but it would have been good to test various input voltage. Surely the efficiency would be lower if the gap between input and ouput is higher. IE solar panel with 12v boosted to 54v. And even better, 12v boosted to 82.8v for a 72v battery.
Well, I’ll do it and make a new video 😊
Good test.
Thank you. I am just about to do another test if this MPPT booster where I will use a lover input voltage to see how it would handle that. I also just received another MPPT booster brand that I will be testing out with the AllPowers 400 watt solar panel. Follow and I’ll have them up in a couple of weeks
i hope to see more vids about this. :)
You will :)
@@ollelund great! :)
Question. When charging a battery you should use a pure sine wave inverter to protect the battery. What type of current does it make?
I'm new to this stuff, thanks for your videos! Will this device stop charging the battery once it hits the voltage you set? Thanks
Yes, it will stop charging when it reaches the set voltage. I have been using this for some time now and it's awesome. One of the best products I have
Nice topic, I'm just about to get one
It is amazing! Unfortunately, I live in Sweden and it has now been five months where testing solar panels is pretty useless. But now the light is starting to come back, so now it's time to do some testing.
And just as in was going to do some testing… 15 cm snow and clouds for the following weeks
@@ollelund got mine already and done testing 2x100watts panels in parallel with 48v lithium 18650 pack. It's working perfectly but a little worried the display shows b: 54v and still rising, c: ranges from 1.0 to 9.0 amps, when the sun shines so bright. Am I destroying my battery with this numbers? My wall charger only has 2amps for 3+hrs. of chargers
@Carlito Madrona Well that depends what you set your maximum charging voltage to. The maximum charging voltage should not be above 54,6v for your 48v pack. Your 18650 pack should be 13x 18650 batteries in series. The max voltage for one 18650 battery is 4,2 so 13 of them should be 54,6 voltage. So 54 voltages should not be a problem. But if you want your battery pack to last longer you could always lover the maximum charge voltage to 53volts. This will give you less watts in your battery pack but you will be able to use ut for more charging cycles. Did you build the battery yourself or did you buy pre-made?
And regarding the amps. I would guess that you have 18v solar panels. (18V x 9A =162W). When the MPPT booster boosts the voltage from 18v to 54 the amps will lower to 3A (54V x 3A = 162W).
So, in conclution, 54 volts is no problem for your battery. But the amps could be a problem IF your battery is very small. But as long as you have a working BMS there shuld be not problem at all!

Thanks, but you tested only DC-DC part. Actual test with solar panel would be better to test MPPT capability. Especially in sunny day with clouds, how fast it finds max power point if it finds at all
I will try to make that test next week!
How do you like this compared to the 7210a that is also listed in yout description?
I like this one a lot better than the 7210a. This one got one bottom. With that button you art what voltage you want to charge with. And that it, that is all the configuration you need. The 7210a is a lot more complicated. But if you want to be able to set all the changing parameters yourself, then you should choose the 7210a. I have never been able to get the 7210a to work as well as this one thou.
I charge my 2 e-bikes with them connected to a old 280 panel on my shed roof
Nice!
Hi, Very nice video guy,
Thank you mate. It means so much to hear that from you. Take care and keep learning!
Hi good video! I have a question about this boost charger, Yours is currently the latest video I can find on here reviewing this product, I ordered a 600w version but it wont get to me for another 5-6 weeks. The question is on the label it says input =12v-50v. If I wanted to charge a 48v battery pack but the source was greater than 50v would this still work? It state its a boost charger so normally the source voltage would be lower. My voltage source will be 50v
I am not sure what MPPT booster you ordered. But if it says input up to 50v I would not use a power source greater than 50v. That might blow a fuse.
An ordinary MPPT takes a higher voltage from solar panel (ex 18v) and lower it to be able to charge a lower voltage battery (ex 12v).
The boost charger does the opposite. It takes a lower voltage (ex 18v) to charge a higher voltage battery (ex 48v).
But!! When charging a battery with a nominal voltage of 48v you dont charge with 48 volts. If it's a battery based on 18650 batteries the charging voltage should be at max 54,6v.
So you can use a 50v power source to charge your 48v battery. BUT! It might be a bit of a gamble depending on the MPPT booster that you are using and what your power source is..
If it has a fuse that will blow at 50,1 volts you might be at risk of blowing that fuse if your power source is not that stable. But most products has fuses that ca survive at least another 10%.
Can I ask what MPPT booster you have bought and what power source you got?
@@ollelund sorry my mistake in what I asked, I meant to ask if I was charging a 24v battery pack and the source was greater than 24v since the label state input is 12-50v. the panels I have have a ocv of 36v but I have a choice of configuring the batteries to either 24v or 48v. I already have a 1200w dc-dc boost converter but it doesnt cut the voltage when the batteries are charged like the unit you have.
With this Bost charger the input must be lower then the output. So if you have a 36v panel you have to configure the batteries to to 48v. If you want to use a 36v solar panel with 24v batteries you must use a regular MPPT.
@@ollelund Thanks for the reply, I just wanted to know if it was a SEPIC (buck/boost) device since the label showed an input which was higher than 2 of the outputs ie 12v &24v
Would like to see the efficiency with a twelve to eighteen volt solar input for fortyeight volts out
Well give me a couple of weeks and I'll post that video for you. Just got to wait for a sunny day here in Sweden. ☺️
@@ollelund i have the same charger with an allpowers 60 watt folding panel that gave me 1 amp in bright sunlight at 36 volts but now i have a 48v e bike , it still slowly charges it though , i only have the 1 watt meter though .
HOWdy O-i-t-F, ...
Thanks

Okay....
This may be a dumb question, but I´m just starting to learn about MPPTs and stuff. So from what I´ve understood so far, the MPPT and the DC-DC boost converter are two separate components, am I right?
There are no dumb questions, but my response time was really slow. Sorry for that.
And you are right, they are two separate components, but here they are the same... I'll try to explain it as simple as possible.
A MPPT controller detects the generated voltage of the solar panel in real time and tracks the highest voltage and current value (VI), enabling the system to charge the battery with maximum output power. With a ordinary MPPT the solar panels voltage needs to be higher than the voltage of the battery.
A DC-DC boost converter basically just boost a lower DC voltage to a higher.
Finally, the MPPT booster is a combination of the two. It allows you to use, for example, a 18v solar panel to charge a 36v battery.
is it waterproof? does it have holes for fan or something like that? :)
It's not waterproof on delivery. I believe that it is dust proof. But!! It has no fan so I guess that it would be able to make it waterproof if you would like to. I will have to order one and try to make it waterproof! I'll order one right away! Follow and I will post a new video later on.
@@ollelund awesome! :)
Is there a BMS (battery management system) in that battery pack? because to the layman watching this test, it might not be obvisous that this is need in a operating system. So it should be pointed out that you are using one or not!! otherwise great video!
This is not a review of the battery pack and that was why I did not go into details about the battery pack. But you are right. The battery pack has both a bms and a fuse built in to it. And I wouldn't recommend anyone to mess around with lithium batteries of they don't know exactly what they are doing. Lithium batteries burns hot and it is almost impossible to put out a fire in a lithium battery.
Don't these voltage fluctuations destroy appliances, specially when on DC?
It's the input voltage that has some fluctuations. Output is steady, or at least within 0,3 voltage.
How can I make this work on my E motorcycle so I can be able to ride long distance
Well first you got to know the battery voltage of your E motorcycle. Then it's just to connect the MPPT bost charger between the solar panel and the E motorcycle battery. Easy as that 👍
You don't divide input voltage and output voltage to determine efficiency. You compare input watts and output watts to determine conversion efficiency. You set the input voltage to a value you chose for the test.
And I didn't .... But it's good that you explain what I didn't do... And you don't set the input voltage. You set the output voltage. The input voltage is whatever the input voltage is. You cant change the input voltage with a mppt.
Yes. The efficiency is measured by the difference between the Watts input and Watts output. From some of your screen shots, this is about 170/190 or 89%. It would have been best to measure the total energy in and total energy out in Watt hours (Wh) but only one snapshot shows that so can't compare.
Thanks for doing this test. I just bought the Renogy Version of this solar boost converter.
I guess you mis-spoke then at 4:16 you said you divided input and output voltages to determine efficiency. That's what the CC displayed. Obviously efficiency is based on input/ output power.
I wonder if it runs hot
You would what? Or are you asking? If it's a question then it's the answer is no. For me it has not been hot at all.
@@ollelund asking
It's 10 watts hot.
🖖
Yes? No? Beam me up Scotty?
If you live in a cold climate and are heating your house.... then place the inefficient devices in the living space , then you are not wasting anything.
That's true. And you just need to live where the temperature is below 19 degrees outdoors 👍👍
That controller is limited to 12v 300w solar panels . No good for my 12v 600w set up
Well you are sort of right. This one cant but they do have one that can handlle up to 600w solar panels.

It says 12v to 50v input on the label
@@ollelund Just wired in the 600w unit today . I used a rotary switch ( 1-off-2) so I can switch between solar panels charging my batteries and inverter #1 . and then #2 is to the 600w boost charger for ebike ( via the panels only )
Нажаль це трошки невірне вимірювання. Ви під'єднайте реальну сонячну панель і тоді насправді побачите ефективність цього контроллера. Вона буде інша.
Yes I know. It’s not a scientific test but more of a way to give an indication about how well it works.
