No matter what the battery status, the screen turns off when the battery is neither charging nor discharging. In the event that I am not connected to the grid, as occurs most of the time with me, the screen will automatically dim around sunset or sunrise when my RV demands equal my solar panels' output. As long as I am connected to the grid and disconnected from the battery, I will see the screen as dark 50% of the time. It will light up if my Morningstar charger feels my battery needs a modest topping It is important to note that even when the charger is in float mode, the screen goes dark as the current is so small as to be almost undetectable.
One in 100.
If you turn off +12VDC at the meter, the amount of current that comes in and goes out may be lost! If the backlight is on, ours shows 0 when the backlight is on. When the battery is drawing 004 amps from the battery, it is extremely sensitive (great) and with a 200 AH LiFePO4 battery, would it take the battery a year or more to discharge?

I spent two hours trying to read the instructions after I had done the physical installation in 10 minutes. You cannot read the icons on the included instructions because they are printed too small. The icons on the instructions printed even smaller than in the online version so it was difficult to tell which buttons to push at what time. Fortunately, I discovered the RV habit article Installation of a full function RV battery monitor. It was a godsend to find this! It took me two minutes to complete the task. display seems to be well made, and I have compared the output with a multimeter, and it seems to be It will take time to find out.
To that end, I would consider purchasing one with a shunt mount if I could find one. You can see photos of a way I found to mount it that appears to work There is just a single gang electric box on the back of the unit, with the shunt mounted on In my case, my other major downside was the fact that the short cable which came off the meter was long enough to reach the shunt in my application without needing the extender cable. I found it to be a great app otherwise.
There is a problem with this battery monitor. Once I was set up correctly, everything worked. Then, I got a message every 12 hours. Following 24 hours, the percentage of the battery is reset to 0%. Since the charge percentage resets, it is difficult to keep track of the current charge level. Amperage and voltage readings are accurate (or within limits), but the current charge state cannot be accurately determined. It is an acceptable product, but it is of low There are a lot of symbols (especially in the instructions) that make it difficult to read. Furthermore, I am not a fan of the way the LED backlight flashes when charging, and stays on when being drawn on. It has to be mounted in an area where the lights won't shine in my face when I have my fan running. Would have liked to have used a higher quality monitor for a few extra dollars.
As well as being quite accurate, it is also very precise. There are some places where the instruction booklet is hard to read, and the set I received was poorly printed. This is my only criticism. I am quite satisfied with my overall experience.
The sampler cable can be obtained from someone, but I'm not sure who.
Set the batteries and tell it when they're full, and it will make the calculations when on load and when charging. Press and hold the right and left side buttons for few seconds) The Shunt does not If you want to mount it creatively, you'll have to think outside the box. It is possible to directly plug in the negative. You may need a battery terminal screwdriver if your battery is screwed in.
I installed it on the golf cart to monitor the charging process. A great deal of accuracy and working well make it an excellent choice. You don't have to mess about with the settings once you're set up - once you're set up, you won't need to bother with them again. Whether it is powered off or on, the settings are saved. The unit draws about 10 milliamps when the backlight is off when powered by 48V. I find the small dot in the decimal point to be annoying It is often difficult to see what is going on. It would also be nice to add different backlight shades (green is currently the only shade). There are a few peeves, but they aren't huge problems.
This product does not yet appear to be installed, but it seems like it is very cheaply made compared to the battery monitors and shunts I have previously used. The hole is too large for the usual 2" hole in your panel, and it looks very chintzy and likely to fail within a few years. The real thing would have been better for me if I had saved my money. The bulk of the work will be installing one of these, and I do not wish to do all that work for it to not be up to the task.
