Digital Multimeter Amp Volt Watt Kwh Meter Panel, DC 6.5-100V 20A | 4 in 1 Ammeter Voltmeter, Voltage Current Power Energy Usage Monitor for Car Motorbike Solar

I was looking to install a 12 volt meter into our power box, and this unit fit the bill well. I really like how the backlight and other incremental settings are stored when the power is out as this is for our garden lights that are turned off from a wifi switch.

Purchased two of these for use in a small 12v solar circuit to measure energy going into and out of battery bank. Outgoing placed between load terminals on charge controller and load, incoming placed between battery terminals on charge controller and battery bank. Each device remembers how much energy has gone thru it. Now I can see how many Wh used from battery and Wh replaced. Very easy to reset each to zero when required. As an example, last night I used 14Wh watching a small TV. This morning (early October) from 4 hours sunshine using 20w solar panel it informed me 16Wh had gone back into the battery. Wiring up quite simple given basic knowledge. Backlight can be turned off. Quite well made and well priced. Accuracy within tolerance for my needs. Only had them for a month but all in all i'm quite happy with the purchase.

Great for measuring volts, amps, watts and total (resettable) watt hours for my solar charging set up. Also paired with a voltage and current adjuster, to charge my electric bike battery when touring/camping.

I bought one of these years ago and probably forgot to leave any feedback at the time, so here goes... This has been running 24/7 monitoring the output from my 260W 60V solar panel array for more years than I can remember. My only minor gripe is that it sometimes randomly forgets the cumulative Wh reading overnight. Other than that, it's still working flawlessly. I'm in the process of upgrading to a Victron SmartSolar MPPT charge controller and a 24V 100Ah LiFePO4 battery. Even though this will give me Bluetooth connectivity via a smartphone with oodles of information, this meter will remain in circuit as a handy at-a-glance monitor of solar input. If you have a solar array with output rated within the safe limits of this meter and need a cheap way to monitor it, I'd highly recommend this meter.

The pass through works ok (the current goes through the unit and the device is being charged). However, there is no display as can be seen on the photo. I would have asked for a replacement, but would probably recieve another broken item. I say this because on the packaging there is a ticked box that states that the product has been tested before despatch! Have returned it for a refund.

Arrived quick, easy to wire up easy to use, just as advertised, it worked well on our wind turbine with a live readout of what's happening and what its produced. Small cost for its effectiveness.

Accurate, results very similar to a calibrated Flukes multimeter.

I'll be using it to monitor the input from my solar panel and then comparing my usage from the battery using a different model from the same manufacturer.

Collegato tra la batteria servizi e le prese a 12v e usb del mio impianto, è ottimo per leggere il voltaggio della batteria che risulta preciso, i watt e gli ampere di assorbimento di qualsiasi utenza collegata. Il display è ampio e luminoso anche in presenza di luce solare, ottima la retroilluminazione blu, attivabile con il tasto a destra. Oltre ad essere molto funzionale è anche un bell'accessorio a livello estetico, ho gradito il fatto che la versione a 12v abbia lo shunt integrato e non esterno. Se vogliamo trovare dei difetti seppur minimi, potrei segnalare la mancanza di viti di fissaggio, ci sono solo due alette in plastica laterali, che lo rendono ideale per l'installazione su supporti plastici o metallici di pochi mm di spessore. Nel mio caso posizionato su un pannello in legno da 1 cm ho dovuto sagomare al mm il foro per un incastro perfetto. Stesso discorso per i cavi in ingresso e uscita, ho dovuto limare il supporto in legno per agevolare l'alloggiamento degli stessi senza stressarli. Nel complesso però un ottimo prodotto, spero che duri nel tempo.

Sehr akkurat. Sehr guter Kontrast auf dem Bildschirm. Nachts gut lesbar mit LED-Hintergrundbeleuchtung. Die Verarbeitungsqualität ist sehr gut. Deutlich besser als vergleichbare Produkte in ähnlicher Preisklasse. Wäre toll gewesen, wenn es Spitzenwerte speichern könnte oder wenn eine UART/Serial-Verbindung vorhanden wäre.

Es muy fácil de instalar y muy útil que mida la potencia instantanea y la energia acumulada
