VIPMOON 150 Amps Power Analyzer, G.T. Power RC Watt Meter with LCD Screen, for RC, Battery, Solar, Wind Power

Very cheap and works perfectly as a Watt Meter - I use for measuring the output from the solar panels on my campervan. Easy to install, can't fault this especially for the price

Don't be without one of these if you are playing with Solar.Its an invaluable piece of kit.

Works as intended.Instruction do not state how to or what pins to use for aux power supply. Only 4 star for because of that.*update*The Wh counter reset after 655Wh. According to the instruction in specifications section: 0-6554Wh, resolution 0.01Wh.According to that it should count to 6.554Kwh not restart counter a 655Wh.The unit did not restart or accidentally switch off, has I can see it as accumulated 54Ah at voltage of approx 30vdc which ties with my other meter 1.6Kwh. Yes I checked it twice to make sure.

Very good product, easy to wire up and displays almost everything you would need to see.I bought a couple of these for a solar energy project and I have to say I'm very impressed with how easy they are to install and also how good they look and display information

Bought this unit to record current from a Solar panel to a battery. However, once the circuit is made the unit indicates anything between 12 and 16mA flow even when there is no current flow.This was independently checked with a multi meter. The error is relatively consistent so I was able to work out how much the current should be but I had to time every test in order to remove the error. Reported this to the seller but they just suggested I try and switch on and off. Despite me saying I had tried this numerous times.Not great

For solar charging, 12V systems on SLA and LiFePO4 batteries this is barely adequate. It will detect current down to 0.10A but only just, never below that. Does not display reverse currents as a minus value. And all the WH and AH values never add up to what is actually in the battery. Is that the batteries fault, charge controllers fault, or this Power Analyzers ? Probably all there is my educated guess.

As shown in the picture this comes with no connectors on the cables, allowing you to put on your own preferred design. Having been used a bit so far it has performed admirably and seems to be fairly accurate.

I bought 1 of these a year ago, and now bought a second as I find them really useful to keep an eye on battery drain in my motorhome when charging gadgets etc. Just for fun I have also run the 2 in series and their readings were near enough identical, very impressed.

Konnte mit Hilfe dieses Wattmeter mehrere Lipo und Blei Batterien "auslitern" und das tatsächliche Speichervermögen ermitteln.Durch die umfangreichen Anschlussmöglichkeiten sind vielseitige Anwendungen möglich

All good

Im Großen und Ganzen ein sehr günstiges Messgerät bei dem die Spannung und Stromwerte stimmen bei den Messungen sehr genau stimmen. Das Display könnte zwar größer sein aber die Werte in weiß sind gut ablesbar auf dem blau beleuchteten Hintergrund. Allerdings speichert das Gerät nicht den höchsten gemessenen Strom und Leistungswert und das ist sehr schade. Ich habe ein baugleiches Produkt einer anderen Firma das zwar nur 130 Ampere ab kann, dafür aber diese Werte speichert.

Fungerar som den skall

Testato con varie correnti e confrontato con altri 4 multimetri (Metrawatt, Fluke, Philips da banco) è abbastanza preciso, con 1A si discosta di 0,04A, stesso valore anche per la tensione 0,06 su 24V.Sicuramente NON sopporta 200A, sul foglio si legge 130A max ma mi terrei sui 40/50A massimo.Siccome tante persone chiedono "come collegare l' alimentazione Ausiliaria" ho allegato un semplice disegno di come io ho collegato il mio, un connettore femmina passo 2,54mm https://www.amazon.it/connettore-dupont-2-54mm-femmina-arduino/dp/B06Y55XJ1B/ref=sr_1_35?__mk_it_IT=%C3%85M%C3%85%C5%BD%C3%95%C3%91&dchild=1&keywords=connettore+femmina+3+poli+2.54&qid=1593522212&sr=8-35L' alimentazione ausiliaria NON serve sopra i 4,5V, le letture vengono falsate.Per quel che costa fa fin troppo bene, lo uso per il controllo di scarica delle batterie con un carico elettronico.
