You need one meter on the panel side before the controller and another meter on the load side after the controller for comparison. The whole idea is to make sure input amp hours is greater than out, not possible using only one of these meters

I REALLY like that set of helping hands you have there! HEAVY DUTY I forget to put the shrink tube on first about 30% of the time.

that wire holder and fan invention is genius. i can't wait to make one.

Finally figured out that this unit can be used to read 12V battery charger output volts and amps. Source side connects to the charger leads and the load side connects to the battery you want to charge. Thanks for sharing.

You have given an excelent explanation here! Thank you very much! Very usefull.

@Benedicto your youtube settings have replies disabled so I can't reply directly. I'm also using a cheapo PWM charge controller with my watt meter and it works fine. You shouldn't need a more expensive MPPT controller to make it work. Of course MPPT is generally better to optimize your solar setup if you can afford it. Did you try swapping the load and source around the other way and checking the readings then?

Thanks for your help Phil. I changed the wiring opposite of yours and it works just fine now. Load to battery, Source to battery terminals on charge controller. Why do you think yours works one way but mine works the other. Again, I am using a GT Power RC watt meter. I think it's very similar to Watts Up. Anyway, thanks again.

Great video and so very clear and helpful...Thank You!

man,i like your setup with the wires and the alligator clips, that's just great...

Great man!! As always we can lear a lot from your videos! Big thanks!!

Super helpful video! Thanks for sharing!

thank you so much this was really helpful

I use 2 , one between the SOLAR and CHARGE CONTROLLER and one between the CHARGE CONTROLLER and the BATTERY. so i know how much power output the solar panel going through the controller, and how much power output is the controller giving the battery .

Thanks brotha, helped me out 👍

Clean setup!!

Great video! I purchased a GT Power RC watt meter and have tested it with a battery charger as the source and a 12V battery as the load. Meter reads all functions perfectly. I attached the watt meter exactly as you have instructed to the charge controller on my small portable solar system and the watt meter will not read any amp functions. The charge controller is a cheap 15 amp unit that came pre-installed on my folding set of two 50W mono panels. Could the problem be with the charge controller? Should I go MPPT? Thanks.

Hey, thanks for awesome video. I hooked one of these babies up. With the load side of it going to my batteries. Only glitch I see is. That when my 21 watt fountain pump powers up. The analyzer goes crazy and starts giving some crazy reading. I have a 25 watt panel, 2 12v LAB'S in parallel = 20ah. And a 21 watt 1.7amp pump. Can you please advice. Much appreciated. Cheers!

wow phil nice setup

I also once have that watt meter but I disconnected it from my off grid system cause I thought it was consuming power from my batts. or maybe I just wired it wrong. I connected the source side to controller and the load side to wire supplying loads. this measures the power I am using. If I flicked a switch to turn on a light it displays amperage of the loads used.

Would that hook up read volts as well as amps/ watts going into the battery. Thanks, I'm learning

Cool soldering rig 👍👍👍

Hi Phil, Could I connect this type of watt meter to a car battery charger. (CTEK). I need to keep a mower battery topped up with this charger. My thinking is with this meter I'd have a visual check on the state of the battery.

Brilliant , thanks

Godbless good job a clear video

very good information

ok, how to wire this watt meter to see the amps and volts produce by the solar panel..... need your help.

Hi, Do you have any updates on how well it is working.

When you hook your battery up and then you hook it up to the charge controller did you put it into the battery terminal Parts on the charge controller

sir can i know the dimension of this wattmeter, and what is the smallest voltage and current it can read. thanks in advance

Phil, how would you use two meters (wired in opposite) to give you solar power in, as well as load out? One meter between panel/battery and one battery/load? Cheers

Does the back light light up when it's during power or should it come on as soon as you connected to the battery

Can you hook up the watts up meter in line from the solar panels to the charge controller to monitor the panels? Thanks

If you just want to measure how much power the solar panel is generating, yes, you can do this :)

Why is the watt meter waking up when it's only connected to the LOAD side? It's reading the voltage and drawing power... why? Will I have to wire another switch there to cut the wattmeter?

A trick to joining those wires is not to twist them but push them together head on so the strands go inside to other wires stands, then solder.

How to connect that watt meter to hybrid charge controller (wind and solar)? please answer my question

Funny I just got one, noticed the only way to get low voltage measurements is to apply a fixed power to pins on side at least 9v-60v

that was informative but you missed out one thing, the wires from the load go the charge controller, are these the middle pins that state battery ? Does it show in watts what the solar panels are producing an how much they have produced in Kwh per day ?

hi, great video, its helped me a lot putting together my 12v lighting in my garage. I have a question, if I had 2 watt meters would it be possible to go from the charge control into meter1 to read panel info then into meter2 to read how much power is being used then into the battery?

Sir your video is very helpful to me. May i know what part of the controller you inserted the two wires of the LOAD SIDE of the watt meter? I mean what is the portion of the controller you inserted the two wires from watt meter? Sorry to ask but i am a newbie & my electricity knowledge is just starting. Thanks.

Please reply! What if I will change the direction, source or load, because when charge controller will charge the battery, current direction will be opposite, it will flow from charge controller to battery, so in this situation will it work, or it will blow the circuit of watt meter? because now the current direction is opposite, please reply

isnt the source the charger? the load is a battery that needs charged? also i was under the impression these only measure in one direction. i was also under the impression you need a shunt if you want to see watts both going into and leaving the battery. am i right? btw i just wired my "watt meter" that can handle 200 amps and it started to melt my thing jumper cables. i was using jumper cables that are about the size of a mutimeter's test probes. also, just a question: how does the charge controller handle seeing the state of the battery though the watt meter? i am concerned the watt meter may interfere with the charger ability to read the battery and either not charge or over charge the battery. i am just trying to learn, not attacking anyone.

Thank you Gadget addict for this wonderful tutorial. I have a question, does it remember the Ah or Wh after power goes off. I mean if i connect this meter between solar and charge controller and when at night solar power goes down , will it remember the next day ?

You didn’t specify where to hook it on the charge controller. I have a load hooked to the PVC side and on the battery side I am in hook to the DC in but I’m getting nothing

Sir.. May i Ask where you bought the deep cycle battery? I've been looking for one for a long time! And how much

What do you use the rasberry Pi for ?

Can you put the battery wires on the battery controller instead of on the battery itself?

Ok I am confused... I have a wind turbine, and solar. They are as far as I am aware the SOURCE... and the LOAD is the battery that is being charged... How is this the other way around? Because if I reverse the wires, the cables run, solar/wind turbine ---> charge controller ---> then LOAD side of watt meter ----> then Battery on SOURCE side...?? How is the solar or wind turbine going through the charge controller a LOAD...? It's the SOURCE OF THE POWER INPUT !! Then the LOAD is what you are charging or using the power for... i.e LED lights etc... Totally confused now...

Hi phil. What am i measuring if i connect the source to my cc and the load connected to the battery? Will i be able to monitor how many Ah I'm using in a given day.

You'll be measuring how much power you're dumping into the battery. Reverse it and you'll be measuring how much you're using (through the charge controller, not including any devices connected directly to the battery).

What if your inverter is connected straight to the battery? And i want to see what's getting pulled out more than what's going into the battery.

When you hooked up that wattmeter you hooked it to the battery side first and then the controller but it looks like you installed it in the battery part of the controller not the solar panel part if you understand what I'm talking about

Hi Phil; You failed to explain what contacts on YOUR CC you connected to. What are they labeled as? i.e.: are they called output meter connections? I ask this because the only other contacts on my CC are for overcharge dump. Is that what they are on yours?

After this vid i got a watt meter and hooked it up between the solar panel and charge controller . But now every new start of the day the watt meters turns on with all weired things on the screen,when i unplug and plug the solar panel back in it starts working again.

Hey Gadget Addict thanks for the video, I have a question for you. Should I wire my inverter straight from the Charge controller or Can I plug it directly from the battery? Some people say that you shouldn't add too much load to the Charge controller and recommend to wire the inverter from the battery? Thanks again!!

You are not allowed to connect the inverter to solar charge controller. Inverter should connect to the battery.

can i put it the other way around? i want to measure how much power it is going in from charge controller to the battery. Well I guess what I want to do is, how much power I have generated for that day. My charge controller doesn't show my that.. It only shows how much power is being generated, volt and amps. Let me know of other option on how I can do that.

Yes that can be done. I gave some alternative wiring options in the video description :)

I have a 10 amp controller and a 300W inverter (600w peak). So I assume I should not connect the inverter to the controller but take it direct from the battery to avoid fying the controller. If so, can I measure the whole power draw from the battery (from the loads on the controller and the inverter) by connecting the my 130amp watt meter as in your video but joining the inverter leads to the lead from the battery to the controller on the controller side of the meter? also. what cabling are you using in your set-up. Thanks - great videos - so clear.

Gadget Addict please respond to this question, i also would like to know this, how to measuse the in and outs from the battery in total!

I want to also measure the the power comming from the solar panels going into the charge controller so I put my meter *(the same as you have) between panel and controller with the controller as load. This works fine. If you have to meters you can see the loss of power caused by the charge controller. . But every morning my meter has crashed. This is because at night it does not get any power and when the sun comes up the voltage slowly rised and the meter crashes dureing start up. So I connect the + and - from the battery I am charging to the external power inputs of the watt meter. But now my charge controller allways sees voltage on the panel side. This is dude too common grounding and I cannot find a solution for it. The only way so far is useing a seperate power supply to power the watt meter but how do I do that when having an offgrid solar setup? Getting an extra panel just so I can charge an other battery to mearuse watt seems a bit crazy.

These pins are used to power the meter when the voltage is below 5 volts or so. The centre pin is positive. One of the outer pins is negative, the other is used to reset the readings. Not sure which way round, and I believe that the reset is not implemented on all models.

Francisco Besana You can use a car battery but it won't survive very long because they're not designed to be regularly and heavily discharged. The battery would charge if you directly connected the solar panel to it but you have no control over the voltage and no protection against over charging. Using the wrong type of battery and not using a charge controller is only going to end in failure. Please be careful and avoid anything dangerous that could hurt someone or cause a fire.

Not sure what its measuring back to front. It depends how watt meter is wired internally I suppose. Great meter either way :D

I see too many of those on KZread. Yes, it is good practice to flux and pre-tin the wires. It is also clever to slip the heat-shrink tubing beforehand than to regret it after. But... Pb/Sn is brazing and not soldering. In other words, it is just skin-deep foreing metal "glue". It is advisable to create a good mechanical bond (twist or crimp of some sort) before brazing. This is common professional practice that any 1st year student in electronics will learn. As a matter of fact, a good side-to-side Pb/Sn brazing is supposed to last for 25 years, whereas a simple dry wire-wrap should last up to 40. For the benefit of all. No offence intended. Good tuto as far as the première intention is concerned!
