## Description

Yunsailing 2 Pcs High Precision Watt Meter Power Analyzer Battery Consumption Performance Monitor with Backlight Digital LCD Screen(9000) - desertcart.com

Review: Useful temporary DC battery/draw monitoring - I got these to monitor power levels and usage for portable radio gear. The wires are sized nicely for 40a Anderson PowerPole type connectors, and the two gave acceptably similar readings when hooked in series. For temporary hookups, these work well. They're well marked and it's easy to tell which is the input and which is the output. Overall, they're a solid choice and a good value.
Review: Accurate, easy to read display that shows what you need to see - These do just what they say - don't be without this kind of readout if you're setting up or monitoring a solar power system! I mounted solar connectors on each side and can insert these meters inline easily. Great for measuring power in and power out of a buck converter. My only minor complaint is that when solar panels are starting to gradually produce power early in the morning as the sky is just getting light, these meters tend to not boot up cleanly and while the background is lit they never display any data, just a line of black rectangles - so if you expect to have one of these readouts inline permanently to constantly monitor power, prepare reset it manually or just supply it with external power.

## Features

- Simple to Read: each watt meter power analyzer is designed with a bright blue backlit LCD display for your reading convenience, allowing you to see the above data clearly in the dark, or even in the sun and other places
- Detect and Calculate Effectively: power monitor can detect the voltage peak, which can not only effectively calculate the voltage, current, power, discharge and discharge time of the aircraft, calculate its force effect, can also be applied for the measurement of small current solar energy, electric vehicles and so on, important for the energy efficiency detection
- High Accuracy: the battery monitor operates in the range of 4.8V to 60V using optional auxiliary batteries; Measurement 0-150A, error 0.01A; Measuring 0-60V with 0.01V resolution; Measurement 0-6554W, resolution 0.01W; Measure 0-65Ah, 0.001Ah resolution; Note: it is suitable for systems below 60V and current below 150A, do not exceed the limit
- Versatile to Apply: our power analyzer with high precision is multi purpose to use, can meet your various work needs; For example, it does well to evaluate RC battery charging efficiency, battery powered device's power and energy consumption, and it can measure the operating voltage, so that the battery, motor, wiring, connector can work properly
- Low Resistance: our battery analyzer adopts quality tin copper core as material, fine in workmanship, low in resistance and stable in function, which can accompany you for a long time; In addition, it is equipped with an exhaust port, expels internal heat, helpful to prolong its service life

## Questions & Answers

**Q: Does the auxiliary power port use Dupont pin connectors (2.54mm), 3 pins in this case?**
A: It has 3 pins but I could not tell you what type that is. I just connect it to a source of power and as long as it is providing power they stay on.

**Q: What is the guage of the wire leads?**
A: About 8 cm.

**Q: can it show current from source to load and load to source?**
A: No, it only provides a current reading in a single direction (source to load).

**Q: Does it show integrated watts (Wh) like the blue version does?**
A: I think the answer to your question is yes. 
As it cycles through various read outs (in lower left corner of display), one of them is total energy measured in Wh. Be aware that once it reaches 6554 Wh, you have to reset it (by disconnecting and then reconnecting it).

### ⭐⭐⭐⭐ My experience using them on solar panels. (I include a suggestion for an auxiliary battery pack.)
*by L***Y on September 11, 2022*

I felt compelled to write a review because there wasn't one at the time I purchased this pair of analyzers. I saw on Amazon that there were several analyzers like these for sale by various sellers and they all looked alike to me - the main difference being whether you needed/wanted 150 A or 200 A limit. I wanted one to connect to solar panels to monitor energy production and troubleshoot low/zero-producing microinverters, and decided on this pair of analyzers because, at least at the time, it had the best unit price ($21.99 for two) - furthermore, having a second one is nice for comparing solar panels. Firstly, be aware that they do not come with any connectors, just 6-cm long cables sticking out, with 4 mm of each end stripped off. One reason for my not rating these analyzers 5-stars is because it was not easy attaching mc4 connectors to them. Let me emphasize that from the info/reviews of the other analyzers like these, their cables were all only 6-cm long. Therefore, this criticism would apply to all of them except the considerably more expensive analyzer that already had mc4's connected to it. I would like for the cables to either have been 8-cm long or stiffer. Luckily though, I discoverable my Craftsman 1/8", 6" long screwdriver could be slid in behind the metal terminal of the mc4 to snap it in place without a lot of trouble. Next, the analyzer can run off the solar panel energy without an auxiliary battery as long as the solar panel voltage does not go below about 4.8 V. Once it does, the analyzer stops (fully) functioning. (Something will still appear on the screen until there's no voltage at all, but it is not what should appear.) This leads to my other reason why I am not rating these analyzers (and, maybe all the others being sold as well) 5-stars: they don't come back to "life" once the source voltage (from the solar panels) increases to about 4.8 V. I found that I had to disconnect them, wait for the analyzer to fully shut off, and then reconnect them. Well, the better alternative was to use an auxiliary battery, for which there is a connection on its side (with polarity symbols on the back of the analyzer). Finding what to buy was a challenge. I think I checked all the analyzers like these being sold, with only one of them saying from what site to go to buy their connectors with wires connected - but without a battery holder. I was going to buy these connectors with wires only, but thought I should first check on battery holders. This is when I found: "4 Cell AA Battery Holder W/JR Style Connector Receiver Battery Pack - 5 Pack - Apex RC Products #2931" Its URL is: https://www.amazon.com/dp/B01NAN66N8 Since it was so inexpensive (a 5 pack for only $9.99) and "Free Returns", I purchased them to try, and found that if I slightly bent the three pins on the analyzer inwards, I could slide on the "JR Style Connector", and it works! - in fact, I've been using the auxiliary battery pack for a couple of weeks now, and it has been working properly. Lastly, I want to share that, even though they are not waterproof, during the couple of weeks I have been using one of them, it has rained, but it has not failed. It is mostly shielded from rain by the solar panel, but nonetheless, what happened one day was that condensation formed on the lower, left side of the inside of the clear plastic covering the screen, making it difficult to read what was under the condensation, but, after the weather cleared that day, so did the screen.
