I have a similar controller.. Solar 30.. Thank you for showing how to alter levels to cutoff panels..
Glad it was helpful!
It is a very cheap and simple charger, it does not indicate charge or discharge amps, nor does it really modify the float voltage.
That's right..better then nothing..
I recently switched to this controller in my van. With the old one, the lights were working perfectly fine, but now with this controller, they sometimes work and sometimes not. I had the impression that the controller has a timer integrated? Is that possible, or what could it else be? On one of the manuals online I saw a little watch in the display but no further explanation. Thank you for helping!
Yes there is a kind of timer only for the output (right last 2 connectors) you can set how long the lights are on, or dusk til down, or 24h means open all the time..but there is no dedicated timer in the real way,. with a watch and fixed hours for on/off...
good explanation by video. i have same model with orange color. it shows ampares also.
It's ok, isn't it?
@@viocaia yes. it is ok

I have just installed a solar system with CM3024Z charge controller and a new 12 Volt battery. It was working well in a week and the battery was boiling during the day, but suddenly its battery acid became less. Then when I added acid to it, the battery doesn't have heat and doesn't boil. The voltage in charge controller shows 12.0 now. However it was showing more than 15 and 16 volts before adding the battery acid. How to solve this issue?
Thanks
There is a problem with your charger..it should stop at max 14.4V ! This model I recall have no settings for voltages so it should stop when the battery is charged.That's why your battery was ''boiling''..the voltage and the current was still running high even after 14.4V.This model, at least the look of this model is copied in so many variants...You should look for another, even a proper MPPT, much secure though ..
Check if you a have menu like PV OFF..that should be at what voltage disconect the panel from charging..that should be from13.7 to 14.4..see if you can adjust that voltage...
What are the in line voltage/current meters that you are using? Great video instructions, thank you.
A couple of PZEM...You can find newer models like PZEM015 very useful and better
Should I increase the float voltage because it cut the power when the battery isn't fully charge
Yes you may...like 14V..?
how did u derive trough ur panel 20v to 14 v?
@@khevzjal1730 yes..
from 20v to 14
Sir my controler does not show the battery percetage I mean the level?
It is looks always empty on LCD
please answer!
It should as long as it's charging..have you tested for charging current? do you have the panel connected and the sign for panel in current?
It's also possible you have another version, there are many same looking with different boards and display

Hi yes mine is the same the display does not show the battery icon filling up ? Maybe this is normal for this model. Otherwise it seems to work ok kind regards keith could anyone tell me if this is normal ???
QUESTION, Hi, I have the same charge controller connected to a 12 v battery on a 12 v / 150 watt solar panel, I am using this setup for lights at night, I am using 3 lights, each light is 5 watt/12 v, i am connecting the lights directly to the battery because the charge controller keeps telling me that it is overloaded even if I haven't connected anything on the load from the solar charger, can anyone tell me if I am doing anything wrong? I am using the lights for our garden and wanted to set it up trough the controller in order to light it up automatically at night. This overload display goes away when the sun starts shining, as soon as the sun goes down shows overload on the screen, at this point the battery is fully charged and shows 13 v, no load on the battery nor on the controller but the screen shows overload, thanks in advanced for your reaction.
Very strange. It shouldn't be a hard task to drive 15W..but this chargers are so ''exotic'' at least the the one I tested it was handling around 10w of LED strips easily.I remeber the voltage on the display it was like .5 out my voltmeter said.If you have the skills, open it up and check for bad solder.Also, change the Mosfet transistor related to output with a marked one.Mine's been no marked at all!
Hope Love yes
Hey! Just give me a hand and subscribe ! Thanks!
The batteries will not change completely because the voltage reading is wrong. Please any help my own is also reading wrong voltage.
Check the battery voltage with a multimeter and make a compare with the one on the display...change the float and max max charge voltage accordingly..
Hi, someone can pleasse give me help, my client has one of this and is burned one transistor, and i can't find the model , thank you in advance
I don't have it anymore, but any MOsfet will do the job, I'll check for you and back with info..
You can try IRFZ44N Mosfet..
How can I get temperature Celsius of this charge controller?
You need an external probe..some of this chargers have a temperature input..I never use that though
Can you give me any advice on my CM5024Z model? Lately the readout on solar and battery is much higher than the reality checked with a multimeter.
Thanks,. J
Can't say..check the mosfet transistors...
how meny dc lod run this charge controler
The direct DC load (out from charger) it's only for small loads, max 10Amps, take it like small LED lights, a laptop, stuffs like this.
If you want to use an inverter, the load should be connected directly to the battery.The PWM charger is checking for voltage and current drop and compensate right away.
You may see in the video, my 600w/220v inverter is connected straight to the battery poles.

Hello everyone, guys tell me such a problem, after the set battery shutdown voltage, the voltage does not stop growing. And the battery starts to boil. What could be the reason???
Try a lower voltage, like 12,5v, also check the battery type from menu

Dear can we use 30 Ampere Controller on 5 Solar panel 150 watt ??
I'm afraid you need a stronger one! You have 750W, this will deliver around 60Ah at 12V full power...but if you'll have a 24V battery pack..it's working, at limit but plausible.Also for a 24V setup will need an extra or use 4 panels, 2 in series and eventually parallel, so it's kind of multiply of 2

Can we charge battery with dc motar by use it...?
I don't think so.If you consider a wind turbine with a DC motor is much more eratic, you need to keep the voltage in between 15-20v (for a 12v battery) that's almost impossible, also you need a shunt connected to the motor for keeping the speed in certain limits when to much wind or finished charge.But there are some dedicated chargers for that.Just google it.
As long as the voltage from the dinamo is in a certain limits , like a solar panel , 15-20v it could work, but I doubt it.Better search for a dedicated wind charger.Plenty of those all around big sellers..
sorry I didn't saw the question! I'm sure you found the answer, but I'm still saying yes, you can use a DC motor like a generator, but it needs to fit the right voltage and amps for your batteries.

Sir..
Could you please explain about temperature sensor cable..??
How to connect in battery..
If you have a single battery just tape it on the side, where the heat is prone to accumulate, if you have more, put it in between batteries as close as possible
I have only one battery..
No need to connect battery terminal..
Senior cable closer to battery...am right
@@nitheeshgopi4580 there is no electrical connection between the sensor and the battery! Just place it with tape on the side.
@@viocaia ok..thanks

Super! Grazias!
Thos Cm3024z without amps in and out is a fake,ussualy the original shows those function, but it work i see. Regards
I have two original ones. And so far works well for couple years already . And left outside.
Marius Macovei 2 modes , one design have ampere display , other design without ampere display
robert kowalewski OK
Nice!
I don't use it anymore, due a Epever MPPT (not such a big deal), but my tests shows that one's been pretty fair for the money.

Can you charge a 12v battery using 24v solar panels with this charge controller?
No, only if you have 24v batteries, so for charging 12v battery you need panels with max 20v and min 15v
Hey! Just give me a hand and subscribe ! Thanks!
450watt is this possible to use it
Almost at the limit, but it should work.BTW 450W offer full power in ideal conditions, in fact you'll have around20-max 25Ah , so you may used it.Also consider working on 24V bateries, that's put the current half..
Hey! Just give me a hand and subscribe ! Thanks!
This is a description of just about any solar controller. Not a real test or review a all.
right! just to see if is working..not a review also, I'm not selling anything, just let people see what I'm buying for my own fun...
With out showing Amp CCt is use less
For a small solar setup, like I have I didn't see any difference in having or not the Amps out indicator.I know as well that my panels can't give more that a certain amps so let's say if you have 150w panel, in full sunny day gives you around 7.5 AH, that's perfect for a 75Ah battery.

This shit don't work...
There are so many looking like that..copies of the copies..I can't say yes or no, no more!
@@viocaia The manufacturer said it works for 12v with 37v panels, but it doesn't.
@@joaocarloskist This is a PWM charger..so 37V for charging 12V battery is way to much..it works with 20V panels..those 36 cell style..You need a MPPT to ''transform'' 37V to 12V without loosing power..
