I have bought 3 of these from 2 different vendors on Ebay. One was the 150 Amp version and the other 2 were the 200 Amp version. The display on all three quit units working shortly after installing them. They still pass current through them....but the display went black on all three. I would not recommend them at all.
Do yours make a high pitched noise? All three of mine do, used for solar input, mppt to battery input and battery output. Noise can get annoying and go right through you sometimes 🤣
So does mine and I have a multi meter that is a lot more accurate. I think this is only useful for people who have bought headless controllers without the display
@@Iridium242 awesome. Gonna purchase one off Amazon. What side goes on battery between charge controller and battery load or source? And can i add one on the solar panel side or can i add to both solar and battery side. Im a newbie to this thanks
Hello Iridium. Could you tell me how can you power OFF this meter? Or does it go automatically off when no charge or discharge is applied? how much does it draw on it own, with nothing else connected to it apart from the battery? Thanks
hi sir, i bought the same item, using it connected to a DC generator goes on and off whenever there is a high enough voltage going through it, worked well for about 2-3days and after it only the backlight is going on and the display is nowhere to find. any tips about this problem? thanks in advance :)
hey , i have the same watt meter but on every start of a new day when the watt meter turns back on again all i get is little squares in the screen not showing any information . if i unplug and plug in again everything works fine again. Any idea why this is happening ?
Cool stuff! Always good to be able to see what is going on at various points in the system. Could you insert one of these on the panel side of your charge controller as well, so you can see the difference between what is coming in from your panels and what is going to your battery bank?
The way he installed it, the watt meter is connected to the battery output of the charge controller. Basically it's between the charge controller and the batteries to monitor power usage. If you want to monitor how much power the solar panel is producing (i.e., watts), put the watt meter between the solar panel and the charge controller. Do not exceed the rated amperage and/or voltage of the meter. Solar panels have been known to fry these meters.
I'm thinking of putting one in between solar panels and charge controller. I want to know the total power my panels make regardless of how much power my controller pulls from them. I want to figure if the panels can charge more batteries than currently hooked up. If you put the meter after the controller. Your only measuring what you give or take? Not the panels full potential. Am I right. I'm trying to understand all this. I will most likely need 2 meters. The second would be to monitor the state of batteries, power in and out.
your question is why i ordered 3 200 amp watt meters. i want one before the charge controller, one after and one headed to the inverter. i havent connected them yet as i need to find a high amp connector so i can quick connect and disconnect them as i need for testing purposes
@@jasonbrown467 I just got this shunt style battery monitor. You should check them out. It's not exactly what your looking for but worth taking a look at. www.amazon.com/dp/B07FGFFHC6?tag=duckduckgo-d-20&linkCode=osi&th=1&psc=1
@@jasonbrown467 for the connectors you might want to look into heavy duty extension cord end plugs. They're ment for 120v at 15 amps (1800watts). Should be fine for 12-24v at 100 amps Could be an easy way to test them out before you buy expensive connectors
@@JoshuaCussins not one of these posts are correct and rather than just being wrong, in this case they can be very dangerous. Please spend some time studying electrical theory for your own benefit and certainly before dishing out blatantly wrong and dangerous advice
is it okey to put that between the battery and power inverter if so how? and the wires are skinny or can i use shunt resistor for this meter if so how?
i would think it would depend on what is the maxium amperage the inverter can draw vs amps that the little metter can handle. i went with a 200 amp version of this so i can do that, but the cables are so small. i realize the length of cable makes a difference in amp load limits on cables too, maybe since the cable is so small it can handle 200 amps? my inverter from my tests so far, as i havent maxed it out yet will draw 220 amps @13 volts dc to produce about 2300 watts ac or so
All well and good but you don't show how to connect the monitor.

Thanks I needed this for my science project
Can you put this on the battery bank instead to just read battery levels Instead of using it on the solar panels? And how would I do that?
Hi, im just wondering I put the cable into the battery slot then do I put in into panel input or to the battery input from the charger controller
I connected my meter the way you described but mine didn't do anything :(
Hi, I have the same power meter, how could I extract the data from this power meter and have it automatically collect in real time on my computer?
There's a 3 pin port on one side. Do you know what this is for? Thanks
Do yours make a high pitched noise? All three of mine do, used for solar input, mppt to battery input and battery output. Noise can get annoying and go right through you sometimes 🤣
Nope no noise on mine
NONE here on two different ones. It's 9-12-2022
Hi, do you know how much power this meter uses itself? No seller says that. ☹️
simplest pwm 20A charge controller consumes less than 10mA. This toy is probably even less.
My charge controller has the meter built in. Nice to have info at a glance.
So does mine and I have a multi meter that is a lot more accurate. I think this is only useful for people who have bought headless controllers without the display
Will the meter frain the battery at night when theres no sun. Whats the meter draw ?
Not much I used it for years and it never drained the battery much if at all

You can’t turn it off unless you disconnect it.

How much electricity does it take to power that meter?
Anything over 4.8 volts.
Nice meter, i need one of those for the solar panels for the camper!
Cool, if you get one and need help setting it up, drive the camper on over here and we can make a day (and a video) out of it :)
Thanks, i will need help with this!
How come mine doesn’t light up?
hey , i have the same watt meter but on every start of a new day when the watt meter turns back on again all i get is little squares in the screen not showing any information . if i unplug and plug in again everything works fine again. Any idea why this is happening ?
Wow that stinks, No idea what is wrong with it. Might be the display as well.
Iridium242 do you have yours connected between the solar panel and charge controller as well and it turns on automatically every day ?
Mine runs 24/7 and mine is set up in between the charge controller and batteries.
i see , when I set it between the charge controller and battery it goes crazy showing 800+watts and 50amps ... lol
Im having the same problem. Please let me know when you see the fix.
I like that thanks for sharing look forward to visit you again thanks for your time wish you well take care

Yup I assume that would work. Might not be perfect as the unit draws some power but it would work.
The watt meter connects to the solar panel input on the charge controller ??? or the battery inputs on the charge controller ???
