T-Trees FT08 RC 150A Watt Meter Power Analyzer With Backlight LCD Hight Precision

I slipped on some 45 amp Anderson powerpole connectors and it does the job. I had to trim some of the insulation back a bit to get each wire/connector in. While the device steadily provides you with the date, it also rotates the bottom left display to convey usage since start of the power draw. A great way to track battery draw if you are not supplementing the battery with solar or some kind of charger.I tested power draw as low as 0.23 amps from a Yaesu 817 up to 20.28 amps from a Yaesu 897 pushing 100 watts.

Below around 8.4V, even with no load, the meter reads a current. At 7V, it reads a 0.56A current under no load. At 6V, it reads 1.10A even under no load. Below 6V, the display is so dim you cannot read it.Above this threshold, it works quite well for a cheap meter. Unfortunately my use was looking at a 5V load and for that it's useless. The box claims 4.8V-60V, but that is far from the truth.

I use it for POTA to keep track my battery condition. I would buy again.

Bought to measure Ah and Wh, doesn’t count correctly above 15A or so. Looks like a software bug. Works fine for power and voltage, not capacity or energy measurements.

A pretty decent power analyzer. I like the back-light and it is indeed a reversed display as shown. I doubt the 150amp rating...maybe for 1 second, but it is otherwise beefy. My only complaint is that when the unit is powered off the juice it's analyzing, it will not tolerate a slow voltage ramp up...ex 0 volts though 6 volts. I have our solar set up run though it and every morning as the array brings up the voltage it causes the unit to freeze at a blank screen. If it starts at 6 volts no problem but ramping up from 0 volts to 6 volts cause the issue.No problem I thought, I will use the external power input...however this has its own caveat. The power input on the side is NOT isolated. When you use the external power port on the side it bleeds a small amount of voltage (~.03v) into the system it's analyzing. It took a lot of trial and error w/ power supplies to get it down to such a small amount. It seems it really needs to be as exact as possible to the power requirements of the analyzer to minimize the amount of voltage it bleeds. This is annoying as it can cause some solar charge controller to think the solar panels are putting out slight power at night, which can cause its own set of issues. Lucky for me my charge controller ignores this slight amount of electricity, so all is well.The other annoying thing about it is the display cycles so fast it's hard to read. I usually need it to cycle a few times before I can read everything. Overall I would rate this as a solid buy.

Based on other reviews, I might have gotten lucky with the one I received. That said, it seems to work great. I haven't tested the readings against a multimeter or anything, but I only need relative readings for my purposes. If you need accurate measurements, I can't say for sure that this is good, but it's consistent and that's exactly what I needed

Worked perfect. I use it all the time in the shop checked usage on coils etc. Lights. Anything really. Love it. It's been pretty accurate so far.

Works really good, But the backlight color makes it hard to read when lights are on. It is a bit easier when the room is dark
