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?

@WattHour 2 года назад

yes it can. you can switch the wires of the sensor to get negative or positive reading.

@brendanstears2977 2 года назад

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?

@sadfur8728 Год назад

Two units would be needed, because the energy accumulation always goes up, never down. It's unable to reverse the count.

@DaytonaShooter Год назад

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. 🙏

@WattHour Год назад

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.

@LA-Creative Год назад

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.

@dinosaurux 3 месяца назад

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?

@glenngemmell397 Год назад

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

@WattHour Год назад

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.

@Akum12345 3 месяца назад

@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 ?

@paulmanhart4481 6 месяцев назад

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

@kletops46 Год назад

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.

@nautic71 2 года назад

What if i dont use the external battery supply, will it still read the energy my load is drawing....or it is just for memory function?

@melihaksoz Год назад

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

@Izinyoka34 7 месяцев назад

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.

@fredericleitenberger2213 2 года назад

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)?

@gamingSlasher 2 года назад

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.

@josepeixoto3384 Год назад

@@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...

@sadfur8728 Год назад

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.

@user-nt3yn7oc1r 8 месяцев назад

Thanks for review. Can this unit calculate decrease of capacity when current flows in reverse direction ? For example, when charging battery?

@odoohub5010 4 месяца назад

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.

@oOBassKillOo Год назад

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!!!

@josepeixoto3384 Год назад

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.

@okrisalrekanugraha1035 Год назад

@josepeixoto3384 Год назад

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?

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.
