Thanks so much WattHour for the explanation how to use the monitor. I bought a 300aH lithium battery with a PZEM-015 already installed in the battery case. I had no idea how to use it.. After a long search I came across your video which is a great help. 🙃
I was thoroughly confused and about to chuck this thing into the trash, but you saved the day! Thank you for explaining how to set up the voltage limits.
This was very helpful I bought a Spartan Power Battery Monitor & Meter with 300A Shunt. The instructions are very hard to understand. This video really help me Thank you!
Very good explanation. One thing I did not like about the meter is the connection, has a tendency for some of the connection wires to easily come out. But apart from that very good meter. Good video.
Two quick questions... 1) what does the reading 'mah capacity ' (top right) refer to? What is this measurement? 2) I'm getting 0 reading for internal battery resistance. Any idea why? Is this an issue? Thanks again for helping so many with your time and expertise. 🙏
Hi, the Ah or mAh is the capacity of that is charged or consumed. Battery capacity is measured with Ah or mAh (milliampere Hour). 2-The ideal internal battery resistance is 0ohm and unlimited current output. but all batteries have internal resistance and this device is calculating approximate value for you at the that particular instance. so do not trust it as battery paraments are changing and you need for complex method to calculate it.
Good reviews you gave the info i was looking for this voltmeter module look very interesting i just bought it and i gonna test with a 12v 154 -200 amp i just learned a bit a bout how a shunt work i'm quite exited to understand how to connect it !
It's a very good Monitor. Just one thing wrong with this Monitor. It doesn't show current direction. So you can't tell the difference between charging and discharging.
This unit counts both ways up,it counts battery charge and discharge as the SAME; in other words, it ADDS the Charge Amp-Hours and the Discharge Amp-Hours, and you really don't know what went on; Is there a way to block one of the ways, for example if the sun( with solar charging of batteries) comes and goes, due to the clouds,and the batteries charge and discharge, is there a way for it to count ONLY the Charging Amp-Hours?
Great video. It explained a lot to me. I still have a question: what is the point of setting cut off voltage? I expect it should be the voltage when discharging should stop automatically, but looking at wiring I do not see any possibility how it might happen for pzem 15. It looks like load and battery are always connected through shunt and the pzem can't stop further discharging. Any explanation?
Hi there Really appreciate the way you’ve done the presentation of setup. I just wanted to ask about charging and discharging. How can I check how many Ah has been charged and how many discharged? Thank you in advance.
@WattHour, how does this monitor behaves differently during charging and discharging ? Can we separately identify whether the battery is being charged or discharged from it's display ?
This is an amazingly thorough walkthrough of this meter. I would have given up at entering the volts with that one button and only 3 digits displayed ! 🤣 Have they made a 3 or 4 button model yet? I’m trying to find a meter that will read both the current and volts on the input side (solar panel to controller) and output (controller load ) but simultaneously. Have been having a hard time.
Very helpful video...love the presentation and the test, especially the setting up. Please can you use a DPDT switch for this unit to monitor both charge and discharge parameters for the batteries?
Hi watthour, does the unit calculate capacity net of charge input? So if I have solar connected delivering current into the battery would this offset against current draw? Or would I need two monitors, one to record charge and one to record discharge?
Hello, If you live in Canada or USA, I am giving away this DL24P 180W load and energy meter. Make sure to sign up for it ruclips.net/video/-UblSfUEY-0/видео.html
From my observation. the energy calculation in WH needs to be seperated for current flowing IN and current flowing OUT. The amount of energy is one way up. The energy (WH) increases, even when the current is flowing in or out of the battery.
Device shows reading correctly but capacity indicator ...Shows the amt it charging.... I purchased with expectation ...It shows capacity of batteries 3.7v 2500mah, 48v 30amh... 2. When screen is off capacity stop increasing.... I expect to shows how much capacity remaining of batteries
Hi. Thanks for the video. I’m using one of these for my 130 VDC, 25 Amp treadmill motor. I understand the 12 VDC connections for display power. But I don’t understand the second set of DC wires you connected at the bottom. Where do these come from? I bring my 12 volt DC wires in for power. I connect my big DC negative to one side of the shunt and it exits to continue to my motor. But I don’t know what to do with the other wires. Can you tell me what I should connect there? Thanks, Paul
Hi just bought this 200v model and a great price thanks for all the info, you have been very helpful just one question I see no one els has asked Can I extend the small wires or do they need to be kept at this length for accurate measurements thanks
Hi, yes I believe you can extend it as this meter does not need current to read. It just need voltage and when there is no current going through the wire , there won’t be any voltage drop and it should not affect reading. Just get for example 10meter wire and measure something and change the wire with 50cm and compare readings.
Hi there Great video. There is just something i want to know further. I am interested in the capacity meter part of the meter. I see that it counts up from 0. so in theory if i have a 100ah battery and that counts up to 10a, then there is 90% of the battery right? So...that is great, but does this automatically reset when the battery starts to charge by my inverter (connected to load) our would it count backwards because the current is flowing the opposite way? - if that is even a thing? Would I always need to reset this value as you have shown? I just like to know the capacity left of my battery each time i use it.
I got the 300ah version of this battery monitor but my question is probably i will use a 100ah gel battery and is it really matter to use 100-200 or 300ah shunt it will not affect the readings is in it? Also i will not draw 300ah from the battery when im using the 300ah shunt i will use it for my campervan for monitoring the currents i hope u understand me
Hello , if i remove the ground probe/sensor cable from the battery , that is used to measure batt voltage , the values in the display change , but its still kind of working . Could you explain what happens in such a szenario ?
i have the 300 one i put in yesterday, its not matching what my mppt screen says except the voltage, i placed this between controller and battery, but wiring i followed picture so that my blue was by the battery, but in reality my battery is the load and so i wonder if i hooked this up wrong?
is this wiring the same if direction is my load is battery and controller battery picture, the red and black go to 48 volts. is current directional with these?
I have just setup and tested the 200a model and at just 40A of current, this meter reads 7 amps higher than the actual current flow. Is there a way to calibrate this inaccuracy? I am comparing measurements with victron smartshunt and also victron bmv712 which are both known to be very accurate. I wish i was seeing the accuracy you got.
Quando ligo os cabos de medição vermelho e preto na bateria o painel do equipamento já liga, então eu não preciso ligar o cabo positivo e negativo do display?
Yeah, that's what (@fredericleitenberger2213 1 year ago) said. Makes this device a lab curiosity I can use on the bench but it won't get installed as a fuel gauge for my truck's auxiliary battery. I'm quite disappointed too. ☹
Amazing video. But one question: I have the PZEM-015 and I want to use it to measure the power produced by my wind turbine. It turns out it counts energy in both directions and does not differentiate. So actually the charge controller of my wind turbine draws about 16watts and the wind turbine barely runs. Now it shows 20kwh but I can't tell whether it is consumed or produced energy. Is there any way to solve this problem (except using a different device)?
OMG, is this true? I was thinking of using it connected at a battery to check the charge state but then you of course need it to count charging as negative until zero AH is reached again.
@@gamingSlasher Yes,it is true,i have it for 2 weeks now, 24h over 24h,and it counts the same in *BOTH* directions! meaning it ADDS the + and the - and counts all as one; so,i do not know how much charge went in... or out; ....a bit stupid if you ask me,and I am thinking of putting a DIODE in the sense line,but then the shunt mV ,which are the AMPS, will be all wrong, and almost useless; still, a very good tool...
You could maybe use a comparator across the current shunt to determine whether it's charging or discharging and then use that output to switch on the power for one of two energy monitors so that one will track charging and the other tracks discharging energy. You would then have to mentally subtract the two to determine whether it's got net positive or negative energy accumulated. When the unit power is turned off it should stop counting so only one of the units should be on at a time depending on what charge/discharge mode it is.
budy you made me watch the video. I have expaliend it . the value you see after the decimal places depend on unit you have on the screen. please watch carefully. I have shown the range.
Bro does it shows the current in 2 direction. I mean . If fix it in my inverter battery side . Does is shows both charging and discharging current? Plz bro . Reply soon .very urgent 😢plz plz plz
Hello, I burned my device, burned companents is U6, thats why I didnt read name of component, please tell me what is this U6, I think voltage reg.? thank u
Hello, So the Ah doesn't show the Capacity of the battery by measurement or calculation. Instead it only is showing the amps that were run through the Shunt and so the Ah is the same as kWh. I wish it had two counters for charging and for discharging so I could see how many kWh the battery was feeded from the solar and how much kWh it spend provided at night... Thank you!!!
Hi, will this account for both change and discharge? Im intending to use this is my solar battery, which is getting charged and discharge all the time. Will this do the coulomb counting accordingly?
Been using it for a while , not useful for that because it ADDS charge Ah and discharge Ah,so you will not know how much went in or out, nor the true SOC, State Of Charge of the batteries; it has a very limited utility, it's good to do a full discharge or a full charge only, with nothing in between.
Hi, i have this, but i didnt not connect any power to the top 2 connections, do i need to do so? I connected to the leisure battery from the bottom 2? And it still turned on, but where do i connect the top 2 connections to? External power? Isnt that just the leisure battery again? So why need 2 lots?
Hi, your question is telling me that you have not watched the video fully. This question is very basic and I have addressed it in the video as to what we connect and where we connect. So please watch the he video fully. I have spent about 2 days (or more)to make the video and if you need to learn you gotta watch it.
@@WattHour so your not willing to answer questions? My monitor is on & what i seem is working with only 1 set of power connections, so why do you need the second set of power?
Hi, internal resistance depends on the state of battery. But if this device shows it, it would be accurate for that particular state of charge. So yes it is accurate. Here is a simple article showing how it is calculated learn.sparkfun.com/tutorials/measuring-internal-resistance-of-batteries/internal-resistance

@@WattHourThanks for replying , I appreciate your input. But I was thinking that this may be caused by wrong wiring order? The instructions say that "the wiring order can't be wrong". But I'm not sure how exactly to do this, the instructions are vague about order. Could you please kindly help me by uploading a photo of your exact wiring so that it is obvious what goes exactly where? Because it's also difficult to tell from just your video please please
@@WattHour yes, in short, it doesn't do SOC. This is despite the three letters "SOC" at the bottom of the bar graph. I am annoyed because I wasted my money. It sounds like I am not alone in my expectations. This device has a current shunt (required to get current data) and claims SOC yet fails to properly implement the feature. Not sure if that is due to a language barrier or the maker doesn't understand what the customers want / need. But it's a fail from me.
hello. very nice video. I have this device but I couldnt understand why do we use LOAD and Battery at the same time? what is load and what is battery in this terminology ? confusing. could you please explain? thanks
Hello, at the input we can have solar panel or power source from wall outlet or a battery. Then for the output we can have batter that is charged from solar panel or wall outlet. If we sit have battery at the output then it we have have a bulb or motor. Any case we can measure the amount of energy .

@@WattHour спасибо за ответ. Если я поставлю данный прибор , для слежения моего 100ач аккумулятора..... Я предполагаю какие там будут высокие токи при запуске машины.... Так вот это устройство не сгорит сразу из-за таких токов ?
I bought it and disappointed. The SOC is fake it's only an estimation based on the battery voltage, not current as it should. Plus it only counts the current while discharging, not charging, so the displayed value is also false if you charge the battery while using it (which most of the time is the case). Useless gadget.
I have the 300 amp one and I program it all wrong. Thanks to you, it's working as intended now. You are a genius. Thank you so much.

6, 9, 12, 15 are all standard voltages. Lithium villages are not used in any devices people use.
How accurate really is the SoC meter? It does not coulomb count, does it?
it just calculates the amount of current and rete of charge current.

It can meat up to 200V . You haven’t watched it then .
How come your meter shows internal resistance when mine just shows zeroes instead ?
not sure. Sometimes people replicate them or may be you got different version if a battery is connected and load is turned ON.
@@WattHourThanks for replying , I appreciate your input. But I was thinking that this may be caused by wrong wiring order? The instructions say that "the wiring order can't be wrong". But I'm not sure how exactly to do this, the instructions are vague about order.
Could you please kindly help me by uploading a photo of your exact wiring so that it is obvious what goes exactly where? Because it's also difficult to tell from just your video
please please
It does not show how much capacity of batteries remain ...Even in full charge ...
It does say if you enter the total capacity of the battery
How do I get the SOC meter to display ??
not SOC but approximate capacity. and I have explained that.
@@WattHour yes, in short, it doesn't do SOC. This is despite the three letters "SOC" at the bottom of the bar graph. I am annoyed because I wasted my money. It sounds like I am not alone in my expectations. This device has a current shunt (required to get current data) and claims SOC yet fails to properly implement the feature. Not sure if that is due to a language barrier or the maker doesn't understand what the customers want / need. But it's a fail from me.
when recharge it need to remove or not
No. It will work. Do not remove it.
thanks bro
Kind sir
I have a 2901Ah 2V Battery
could this watt meter calculate the capacity?
Yes it can.
But it says on the video that the maximum capacity is 999Ah
Right?
It should be 4 digits 9999
No i think its a 3 digit
Could you check for me because this is a necessary for me
hello. very nice video. I have this device but I couldnt understand why do we use LOAD and Battery at the same time? what is load and what is battery in this terminology ? confusing. could you please explain? thanks
Hello, at the input we can have solar panel or power source from wall outlet or a battery. Then for the output we can have batter that is charged from solar panel or wall outlet. If we sit have battery at the output then it we have have a bulb or motor. Any case we can measure the amount of energy .
Internal resistance doesn't look correct for the lifepo4.
Как считаете, обычный автосаинец его поставить? Погибнет из-30 заизаода авто атот прибор ?
Когда я перевожу ваш текст с помощью Google. У меня получилось так: "Ты думаешь обычный авто вести его ставить? Авто устройство умрет от-30 заводского?" что не имеет смысла. поэтому, пожалуйста, используйте очень простые слова, чтобы Google мог их перевести. Спасибо
@@WattHour спасибо за ответ. Если я поставлю данный прибор , для слежения моего 100ач аккумулятора..... Я предполагаю какие там будут высокие токи при запуске машины.... Так вот это устройство не сгорит сразу из-за таких токов ?
WattHour = RoboJax ?
Separated all energy and power related stuff
no idea how the capacity is suppose to work

I bought it and disappointed. The SOC is fake it's only an estimation based on the battery voltage, not current as it should. Plus it only counts the current while discharging, not charging, so the displayed value is also false if you charge the battery while using it (which most of the time is the case). Useless gadget.
Have you found anything that is more accurate- would love to purchase…. Thanks
@@apjbuilder there are many but more expensive. I kept this one and use the bsm bultin one for more details.
Not a good design of setting
Indeed. But I did my best to present it in the best possible way.
@@WattHour You did good
