PowerMon is a Bluetooth hi-tech device that can be used to monitor the state of charge of any battery and power flow in any electrical system. The data logging function allows it to store measurements for up to 3 years. The storage is on board the device not in the mobile app.
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 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.
United StatesWorks great. Easy to configure. My only complaint is that the phone app doesn't have a users guide that I can find. I found the manuals for the monitor itself. Was easy to connect. And works great. The app took some trial and error but It works well too.
United StatesNeet product. Great support.
