Testing out an 100A hall sensor wireless battery monitor. Great for monitoring your shed or garage from the house! Buy it from Ebay for $32. Not bad considering a basic 100A shunt meter is atleast $20. ebay.us/ar85VH
Hi Steven, I'm from German and have the same Amp/Volt/Wattmeter. Sorry, my english is bad. There is a secret menu where you can set the volt and ampere accuracy. Simply go to NCP and press the middle button for about 4 seconds. Now the volts can range from 0-20, 20-120 volts and the Amp can be fine-tuned from -0-100 / + 0-100. Would be nice if you could make a video of it. This measuring device is therefore very accurate.
Mike thanks for the tip. I have same model but it constantly reads +\-2v less than actual I hoped this would fix it but it doesn’t. It’s 100% the battery monitor as I have had 2 different multimeters and another battery monitor that read correct volts? Anyone any ideas?
Do you think that powering the main board (through a step down) and feeding it 100v dc to its voltage reading port, all of this simultaneusly through the same switch on the 100v cable, might do harm to it? Or it has to be first powered on, get the things running in it, and then switch on the main power to its voltage reading port? Thanks.
Hi there. I bought one of these meters 2 years ago and my auto electrician set it up when he installed it. I have to reset it again and have managed to all but the BPC. I put the dot next to the BPC, press the middle button which makes the BPC red, then using the top button I take the '0' number in the left, middle box to 100 and press the middle button again to set. But, the 100 goes back to '0'. Can you tell me why this is, I hope you can help. Thank you
Hi Steve... my voltage is at 13.5v but the AH at 67% and dropping. The BAT is set at 400AH and the BPC at 100%..batteries fully charged. Any ideas why AH going down in graphic and % reading? thanks
Hi, besides the usb port of the display is there another place to connect it to power? Or I have to cut an usb cable and hook an aux batt there? I want it self power
Great review thanks. I ordered one and have it set up in my caravan. Seems to work ok however the voltage percentage, after setting at 100% when fully charged has slowly dropped to 73% and falling despite my batteries being fully charged to 100% according to my other battery meter???? When I reset it to 100% it reverts back to 73% Any ideas? Many thanks in advance
Mine doesn't show the kwh consumed, any ideea why? It's shown in this video from min 02:00. And I've also discharged a big li ion battery at 400wh for three hours and still zero at kwh display. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IizMHywbKl8.html Thanks!
so i am guessing this unit is only one direction not bidirectional so can not measure charge and discharge if it is bidirectional then shouldent it be on the battery neg cable
@@stevenc22 id flip the sensor around then to me negative reading are loads think it makes more sense that way handy little unit out of all the meters i have used over the years they always need modifying to read the same
It's not too bad. Mine is accurate within an amp or so. Good for monitoring a shed from the house. I don't rely on it for anything, I have a BMS and a smart charge controller, this is just a visual indicator.
You totally skipped the battery capacity setting and set it at %100. Without the battery capacity setting the displays reading on how long it takes to charge or discharge at whatever % is no good. You also didn't reset the meter when there was no current. That 0s it like a scale. I was hoping this video might show the charge and discharge relays but you skipped that also. I don't see how there's any protection without hooking up the relays unless you consider an alarm protection. Thats more like a over under voltage warning than protection.
My friend Mike who thinks he knows everything says that's a transformer not a hall effects sensor... Is he right or are you? I hope you are... He's really arrogant and I want to prove him wrong.
Lol. He is wrong. A hall effect sensor measures magnetic fields and that is how this meter works by measuring the magnetic field of the current flow. A transformer takes a voltage and steps it up or down but it does work similarly to the hall effect sensor.
Actually your friend isn’t too far off! for AC current a conventional amp clamp uses a transformer to turn the reading into DC so the amp meter can read it. The Hall effect sensor is used on DC since the magnetic field of a wire with DC current is a constant and does not Fluctuate back and forth like AC.
