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 s. . .

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.
The thing is super cool, its like it says, a swiss army knife. There were so many choices I had to pause and think about what I wanted to do. I will be buying another one for my next project for sure! Customer Support was great, especially after I fried my first one (don't hook them up backwards...).
This unit has worked great for solar input charging in our lab so far.
I have one of these already on my camp trailer and have been very pleased with it so I purchased a second to monitor a 100AH LiFePO4 battery. The hardest part about the install is figuring out how to layout the install.The device itself is simple to wire in.
This is the second unit that I have purchased. These units are perfect for monitoring and controlling all types of battery projects. I currently use this one to control and monitor a 24V 400aH AGM battery stack in parallel with a 510aH NMC lithium stack for my inverter. I am able to monitor both the battery and the common bus using this device, and also control the charging current and discharge current using an external current shunt. Wish I had a couple more. It is great being able to poll the device and also switch it on or off over bluetooth with my phone. The range is also terrific. I can pick up the signal from my office and the equipment is located in my laundry room, quite a good distance away. This is what I was going to design myself......, saved me the trouble!! Good job Thornwave.
Easy to install, very good Instruction Manual, interface is simple but versatile and informative. EAGERLY awaiting data logging software AND the touch-screen panel interface! Good friend just ordered his, I may get another for battery testing.
