AC 80-260V 100A LCD Digital Display Multi-Function Power Monitor 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 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!

Working flawlessly. Easy to install for great price!!!

good meter. its been working fine with the backlight always on for over a year. im using it to track EV charger on 220v

I used these to monitor power so I didn't exceed the generators capacity during hurricane season. It also gives you a good indication of what your power bill is going to be.

It's fun to put it inside an enclosure. The process involves cutting and wiring. But the result is great. I bought total four of this to monitor my critical loads.

Works but the KW usage is not accurate. Not useful if you want to know how many Kilo Watts you using.

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.
