AC 80-260V 100A Multi-Function Power Monitor LCD Digital Display Voltage Current Frequency Power Factor Energy Meter Ammeter Voltmeter with Split Core Current Transformer

This multifunction power monitor is a great tool for tracking energy usage. The LCD display is bright and easy to read, showing voltage, current, frequency, power factor, and energy consumption clearly. Installation was straightforward with the split-core CT—no need to disconnect wires. It handles a wide voltage range (80-260V) and up to 100A, perfect for monitoring appliances or DIY solar setups. Very useful for identifying energy drains in the home!

I recently installed a backup generator for power outages. I installed this meter in the transfer switch panel to monitor both Line & Gen power. It works perfectly, and for the price, it can't be beat. Thus far, it has accurately monitored the average Wattage in real-time, current Amperage, Hz, and most importantly, a cumulative kWh reading until its reset. It also monitors how efficient your utility company is providing power to you (Power Factor). Interestingly, while performing generator tests, I discovered my generator is actually more efficient than my Utility company! I'm very satisfied with this product.

Installed in my RV does a great job in letting me know when I am close to over amping my system in the rv park.

It works and has worked for many months but resetting the KWh when it maxes out at 999 KWh, is not easy to do. More importantly is why it doesn't just simply roll over and not require a reset. When it maxes out I lose the power info but if it rolled over and its being monitored I wouldn't lose the power info.

I use two of these devices to monitor my AC and furnace. The use of a current transformer instead of a shunt makes easy and , in my opinion, safer. Make sure that you remove power to the equipment before installing. House power is potentially lethal.

I originally bought two of these to monitor a generator circuit that I'm installing for my house. But first, I wanted to see how much power my house was using so that I could make sure to not overload my generator. After installing two of them on the main lugs, I decided that I would keep them, because it's nice to see how much electricity your house is using at all times. The wiring is easy. If you're looking at the back of the box, the current transformer (CT) goes into the top two terminals (doesn't matter which color goes in the top or bottom). Then, your 'hot' wire goes into the third terminal and the neutral wire goes in the bottom terminal. I was able to wire these while my panel was hot. I have the 'hot' wires coming out of my 30A dryer breaker, so I was able to cut it off while wiring. I'm using 10GA wiring and it fits inside the screw terminals. ONE THING TO NOTE! Do not attach the current transformers to the live wires without already having it screwed into the meter. Google risks of an open CT and you'll see why. Overall, I'm super satisfied with the meters. The light is bright and the numbers are easy to read. They seem accurate, but I don't have any way to prove that. Also, since I had four of these at my panel, I bought a sheet of ABS plastic to mount them into and they look nice!

Arrived in the normal time, packed well, and exactly what I ordered. I use this meter to monitor the inverter I use on my solar system. I like that the pertinent information is all right there on one display, and I don't have to scroll through menus to find the data I'm looking for. It's been installed roughly 6 months with no problems so far.

The meter provides accurate real-time information. Additionally, the current transformer cable can be extended up to 1 meter without losing measurement accuracy
