Review: Wanted to get a power meter to figure out how much power my tent trailer used on a typical trip. we are taking a 3-week off-grid trip this summer and needed to know if solar can charge the batteries or if we need a generator. Originally was just going to hook up in the circuit temporarily and take some measurements, but once i hooked it up it seems like really valuable info to have all the time. I installed the meter in the cupboard below the galley on my tent trailer and tapped into the wire coming from the batteries back to the inverter. Seems to work great so far, only been installed a few days, but so nice to have accurate information about how much energy my tent trailer uses!
Review: The meter works as advertised and for the price it has excellent value. Note that the current meter is in the negative side between DC IN - and Load -. This is important if you use a switch, like I do, to change the meter's polarity between charging and discharging a battery. The current meter will not run backwards. In other words, the meter will only increase its reading when positive current flows in the direction of DC IN + to Load +. Current will flow in the other direction, but the power and current meters will not read negative values, and the Watt-hour meter will not decrease its reading. To use the meter to monitor power from a solar panel to a battery, I connect the solar panel to the DC IN + and DC IN - terminals, and the battery itself to the Load + and Load - terminals. When discharging the battery into the intended load, I reconnect the meter (using a switch) into its conventional connection topology. Since the current meter is in the negative side, DC IN + and Load + are connected together in the unit. In other words, they are the same node. The unit is made to mount in a square hole in 0.032" thick material. I used a thin bead of Silicone adhesive around the bezel to strengthen this mechanical connection. The operation of the screw terminals can be confusing, and can lead to damage if one is not careful. They come tightened down, so to connect a wire first loosen the terminal by turning the screw counterclockwise several turns, insert the wire in the gap that's just been opened, and then tighten the screw in a clockwise direction. I verified that the terminal block will accept 12 gauge wire.

## Features

- The portable multi-meter has a Large-screen LCD, can display voltage, current, power, energy at the same time, bright and easy to read.
- Voltage test range: DC 6.5 100V; Current test range: 0 20A; Power test range: 0 2KW; Energy test range: 0 9999kWh.
- Multifunctional: the accumulated energy can be reset by button; Store data when power off; Voltage alarm function (over voltage alarm threshold, backlight and voltage will flash to alarm).
- Easy to hook up: with built-in shunt, 2 wires in (DC + and -) and 2 wires out (The Load), all connections are via a 4 point terminal strip(has a wiring diagram on its back).
- The blue backlight can be turned on/off by the front accessible recessed switch located on the right side bezel.

## Questions & Answers

**Q: Can the voltage be calibrated?  Mine was accurate initially but now displays ~19v with a 12v line supply. The load side reads 12v with a multimeter.**
A: Same thing happened after 2 months to mine!!! I was wondering what happened. My solar panels produce about 36 volts, now it's displaying 50-60, throwing the wattage reading way off. If anyone knows how to calibrate it, let us know please.

**Q: How do you hook up this gauge with its tiny wires/connections when all of the cabling in a solar system is much heavier gauge? seems like a botleneck!**
A: All of the current ( AMPS)  go through the SHUNT ( rated at 20 AMPS ) the small wires that go to the display unit from the SHUNT are only supplying very low current / low voltage to the display unit that gives it the value of the current ( AMPS ) that are passing through the SHUNT. I have the 100 AMP SHUNT version of this unit and it works very well. Again, all the current and the voltage your measuring with this unit are derived at the SHUNT and it can handle a lot of current and will NOT restrict or bottleneck the current or the voltage you want to measure. Hope this helps.

**Q: What is "dc in" in the diagram on the back of the device? is it battery?**
A: This is the dc from the source that you want to monitor. It could be from a battery, power supply, solar cell, generator, etc.

**Q: The button for backlight looks recessed. Do you need something like a pen to push the button?**
A: Yes! And it is also used to set several parameters which is OK if your use is in a PERMANENT setup. In my case it is only a test meter, and it becomes a pain to just reset the Watt.Hr meter...  Also everytime it is powered up the backlight comes up flashing... Neat instrument otherwise..

*by G***G on 26 July 2018*

PROs: Good price. Works great. I love the on/off back-light display. Very accurate numbers (matches very close to my high quality multimeter). I use it on a 12VDC battery/solar powered iPod charger/stereo external speaker amplifier system (camping). The unit itself consumes 0.8mA @12VDC with back-light off and 2.8mA @12VDC with back-light on. I have an external switch so I can monitor solar power in OR load power out. Cons: Only con is that the current unit resolution is too large. The 0-20A minimum current that it reads is 10mA (10,20,30 etc). I would have liked it to have 1mA range, or better yet Selectable: 0-19.999A range with 1mA resolution and a 0-1.9999A range with 0.1mA resolution. (Power and W.Hr to scale by 10 also).
