RGBZONE 200Amps Power Analyzer, High Precision RC Watt Meter with Digital LCD Screen for RC, Battery, Solar, Wind Power (200 Amps)

Like being able to see how many amps and wattage my solar produced

Does a great job.

wish it flowed both ways,,, otherwise perfect

Update: removed a star because the watt hours actually resets after ~660Wh. Not the 6550Wh in the specs. I bought another unit and it does the exact same thing. Which makes this way, way off specs by an order of magnitude. Maybe the zero on the end is a misprint. This makes it almost useless for tracking how much Wh was used. Extremely disappointing actually, as this was the main thing I wanted these for.People are saying incorrect things about this item. It actually refreshes the rotating data queue values for Minimum Volts, Amp hours, Watt Hours, Amps peak, and Watts peak every two seconds, not four times a second, and there is plenty of time to read the values before they switch to the next data queue.Amps, Voltage, and Watts are always on the screen and are updating fast. These are the real-time data values. But they are always on the screen so they are not a problem to keep track of. And if you cannot keep up with the refresh to see the precise values that matter, that is what the minimum voltage, peak amps, and peak watts is for, in the data queue. Seems like a great setup to me, shows me everything I need. The only thing I would add to the data queue is a peak voltage to go along with the minimum voltage for those that need that.The display is a bit hard to read at first though because it has a strange ghost of the next value it is going to display for about a 10th of a second before the actual numbers change. Difficult to describe. This makes it slightly hard to read at first. But you get used to it, and it is not really a big deal.I agree with the other reviewers that the wires are way too short!!!! But the tinned ends are perfect, don’t know why anyone wouldn’t want tinned ends. Installing your own plugs is so much easier with pre-tinned ends.I have not measured the accuracy for the amps yet. And have not checked the volts with a multimeter yet. But the watts and volts agree with my charge controller as close as can be expected as this refreshes faster than the charge controller, and these things can vary a lot in the time it takes the controller to update.Fix the too short wires, even just one more inch would be somewhat acceptable, 2-3 inches even better... and then it would be a 5 star product for me.Couple minor things, I wish the watt hours went up to a higher cumulative value in the data queue. 6554 watt hours is just not high enough. And actually 100 amp hours would be better than the 65 amp hour cumulative limit on the data queue, as well.

Good quality DC meter, very easy to read. Wired it inline with a solar panel to monitor the output. Have also used it to check the power draw for products such as CPAP machines when running from batteries and/or DC power supplies.Very pleased, would buy again.

Haven't had a chance to use it yet because the wires are too short. If you're trying to put specific terminals for your application, they don't leave the wires long enough for you to do that. Suggestion to the manufacturers: Send them with longer wires. Don't tin the ends! Allow the purchaser to do those things. You're not helping

I needed to know if edf motors were pulling the same amps. Works as described.

This meter is only accurate at 10A or less.. I used to capacity test a lifepo4 battery and was putting 20A in and it only registered 9A. However at 10A is was ok. Also, the screen flashes way to quick to read and the wires are too short. I do not recommend this meter.

Great meter, either for permanent mount or quick connect for testing. Mounted this behind a 24 volt to 12 volt buck converter to read voltage and wattage draw. Works perfect. Would be nice if it had mounting holes. Space away from wall for venting!

Conforme à la description.Livraison par la poste suivi correct.À voir dans le temps.

Bon qualité prix

good price, accurate, however cables are a little short

Great to know what is actually coming out of my solar panels. I bought this because I didn't know if my batteries were dying or if a panel(s) were shot. Turned out one of my bigger panels was completely dead.
