## Description

Product description 200A HIGH PRECISION POWER ANALYZER WATT METER Makefire professional aeromodelling equipment manufacturer, to provide you with a full set of aeromodelling equipment. Wondering how much electricity your solar system produces but don't have the right tools? A power meter is an excellent choice for you! If you simply connect this device to your solar system, you will be able to evaluate how efficiently the system is operating. 16*2 LCD backlit LCD yellow screen with black fonts, the display is clearer, and the direct sunlight does not affect the viewing data. The 12AWG soft silicone cable lengthened to 22cm can be more free to DIY the analysis, testing and troubleshooting of your DC power supply projects. Accurate measurement hardware and software program calibration can make our product voltage and current error within the range of ±0.1. The wire is made of high-quality tinned copper core, which has strong carrying capacity and low resistance. The core is wrapped by soft silicone. The wattmeter has a heat dissipation hole design, which can dredge the internal heat to the outside, and ensure the stable output of the device for a long time. This is an 8-in-1 tester, which can be used in many fields such as the detection of solar cells and model aircraft batteries. EXTERNAL POWER SUPPLY PIN1 is GND pin; PIN2 is VDD pin; PIN3 is DATA pin. External power interface: JR (Jerry rig) connector. When the input voltage of the power meter (such as lower than 9V) cannot be displayed on the screen, you can connect an external DC power supply with a voltage of about 12V through PIN1 and PIN2 to supply power to the power meter and let its display display test data. (PIN1 is negative, PIN2 is positive)

Review: Exceptional Performance and Reliability: Makerfire 200A Upgraded Watt Meter - 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!

### ⭐⭐⭐⭐⭐ Amazing product and reliable too

Works great

### ⭐⭐⭐⭐ Easy to install but watch the front lablel
*by L***E on September 28, 2023*

This power meter is easy to install. I put 3 on the output of my solar controllers. The 3rd one I installed had the front label on wrong. The Load and Source was backwards. The Source always goes to the end with the small 3 prong plugin. One of the 3 had that labeled as the load. But hey they work well and are easy to read. Only gripe is you cant reset the meter readings.
