Makerfire 200A Upgraded Watt Meter with Longer Wire, High Precision Power Analyzer Battery Testers Voltage Amp Consumption Performance Monitor with LCD Backlight Screen for RC,Solar,Wind Power,Ebike

I recently purchased the Makerfire 200A Upgraded Watt Meter for my solar off-grid installation, and I must say, I'm thoroughly impressed by its performance and features. Firstly, the longer wire design is a significant upgrade. It offers more flexibility during modification and testing, allowing for a more convenient setup. This design consideration shows that Makerfire understands the needs of its users. The precision of this watt meter is remarkable. It measures voltage, current, and power with high accuracy, which is crucial for monitoring the efficiency and health of my solar setup. I've compared it with other meters, and the Makerfire consistently provides reliable and consistent readings. Another standout feature is the LCD Backlight Screen. It's clear, easy to read, and the backlight is a godsend in low-light conditions. This makes monitoring my system's performance hassle-free, regardless of the time of day. As for its power consumption and performance monitoring capabilities, the Makerfire 200A Watt Meter has been invaluable in optimizing my solar installation. It's helped me understand my system's output and consumption better, allowing me to make informed decisions to improve efficiency. Durability-wise, the meter feels robust and well-built. It gives me confidence that it will withstand the rigors of regular use in an outdoor environment. Overall, the Makerfire 200A Upgraded Watt Meter is a top-notch tool for anyone involved in solar installations or any application requiring precise power monitoring. Its combination of accuracy, ease of use, and robust design makes it an excellent investment for both professional and hobbyist use. Highly recommended!

Works great

I have a couple of similar meters and wanted to get one with slightly longer leads. (A lot of them only give you only a couple inches of wire to work with). This one has much longer leads and also has a light background screen with dark characters instead of the inverted dark screen with light characters. I find this configuration easier to read. So far it's been working just fine. Power measurements between my three different meters are almost the same, so they appear to be fairly accurate. PowerWerx, whom I consider to be a reputable company lists their meter with 12 AWG cables as 100 amp peak, and 45 amp continuous. Even their model with the beefy 8AWG cable is only rated at 140 amps peak. My guess is that the specs on this model are overrated. Even though it's listed as 200A Peak and 50A continuous, I'm going to treat it as 100A/45A. I'd be willing to bet that the guts in this unit aren't any more robust that the PowerWerx unit.

It worked 35 days then failed. Update, system took a lightning strike . Ironically, the meter is fine.

Its pretty good

I might be too picky in this review but it works very well you have to have a good soldering technique to solder on your connectors because 12 gauge wire gets a little tricky with the heat The cheap part that I don’t like and I bought two of these hoping the second one would be different and it was not is “the plastic face is a very thin thin piece of plastic that Glooze around the edges and it bubbles up half of it comes off and it’s very hokey I bought another brand from tool kit RC it’s 150 amp watt meter, it has a pop out dial where you can increase the voltage going in and get different readings it has a graph and a dial it’s by far the best one on the market but it was about $50 but if you’re serious about your plans it’s a great bye, this particular wattmeter here is just not something I would buy again just for the fact of the face plate is a cheap thin plastic film that does not lay flat and secure

I love this unit. Very accurate. Yellow background makes it easy to see. I have 5 across my build. The wires and box heats up with a consistent 50 amps. Wires have made it to 118 degrees. No melting, just softness.
