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.
United StatesI am able to view history on the android app, but can't figure out how to download data to a file. Any ideas?
United StatesI was looking for a quality battery monitor for months and gave up on the cheap units flooding Amazon and eBay. I started looking at the established big name brands and only found poor reviews. I luckily found this unit and installed it with a solid state relay. Together they have worked flawlessly on my auxiliary battery system in my 4WD. I can remotely monitor the battery, set protection thresholds and turn loads on and off. I couldn’t ask for more. I plan to buy another for my main battery and for my second 4WD system.
United StatesUnfortunately I only read the reviews on the "Smart Shunt" from another company, a company that am usually impressed with, after installing their device and finding the Bluetooth barely connected up to 6 feet away with my RV basement battery compartment door open, and maybe 3 feet with the door closed. In reading these reviews a fellow mentioned the Thornwave solution. After a telephone conversation with tech support (Razvan), I made the purchase. I can only say, thus far I am completely satisfied and impressed. By the way, the high dollar vendor doesn't even give you real data logging, this solution does! The Bluetooth is just phenomenal as I can connector to my rig 50 feet away with the battery compartment door closed, even inside my house! I'll be cheering this little start up on and looking for even more innovative products for the RV and Marine communities.
United StatesMy order was handled very professionally. I needed assistance on a couple of tech aspects and received outstanding support from Razvan. He was patient and helpful and work closely with me to make sure the monitor was working properly. This monitor is technically sophisticated and the mobile app is extremely well designed. I highly recommend this company's professional product and commitment to responsive service
United StatesI was so impressed with the Bluetooth Battery Monitor that I bought a second one for my charge controller. Excellent build quality and goo bluetooth signal. Only have yet to find how to get the historical data working.
