On top of the monitoring functions, PowerMon can act as a power controller, allowing for low voltage disconnect, high voltage disconnect, over-current disconnect, battery isolator, remote ON/OFF switch, timer switch, generator control, and solar system automation. With Bluetooth LE (Smart) connectivity there is no need for drilling and extra wiring in existing or new applications (RVs, boats, solar systems). Small form factor and ease of installation make PowerMon ideal for quickly adding smarts to any existing electrical system. Remotely monitoring DC circuit parameters has never been easier!
Voltage, current, power, energy, battery state of charge, and temperature are all measured and displayed in real-time using Thornwave Labs’ mobile application, PowerMon, which is offered for free on Google Play and Apple App Store. The device supports multiple configurations and measurement ranges that can be set up using the app, allowing it to accommodate a variety of circuits. Control of a mechanical or solid-state relay allows it to be used for low voltage disconnect, high voltage disconnect, over-current disconnect, a battery isolator for multiple battery systems, remote power control, or as timer. This wireless, multi-function tool is truly a Swiss-army knife for DC electrical systems.
The device measures two voltages up to 75V with better than 0.5% accuracy. It contains an internal shunt making it able to measure current up to 60A without using any external parts. The current measurement can be calibrated to an accuracy better than 1%. If higher current has to be measured (as high as 10,000A), an external shunt can be added. Current shunts are readily available and can be customized for the specific current measurement range required. PowerMon supports a wide range of current shunts.
CanadaI have never owned a phone. I was born approximately 60 million years ago, I have a Luddite accent. I now have a phone a smart phone. This was very easy to set up. and install. I have installed mine in a 1958 x Greyhound bus. I can get info for the batteries 40 feet easily from the bus.
United StatesHas a lot of functionality. Great Bluetooth range 60+ feet enclosed in a metal battery box. Would like to see some timers associated to voltages or current. Example, if current >200A for 15 min., turn relay relay on or off for x time.
United StatesThis monitor has excellent accuracy, easy to configure control for relay, reads and controls output from over 50ft away from the device and is great for tracking charge and discharge rate for improving your use pattern in RV, vehicle, or external battery packs.
CanadaInstall and instructions were very clear. Worked with existing shunt I already had. Read the manual if you see strange values :) - fixed my issues after reading the manual LOL. Great BT signal strength to monitor from a distance. Can monitor the battery health of our camper from the drivers seat of the tow vehicle. One area I would like to see improvement on is logging. I can only seem to get logging on voltage levels. I would like to see logging on current draw as well. Highly recommend this item for your monitoring needs.
United StatesJust love this thing, not much else to say, other then the support is just as good as the device. I've installed the Powermon with the precision external shunt on several RV's now and it is simple to install and super easy to use. The fact that it has on board storage capability places it far and above the competition.
