We developed the PowerMon device because we wanted an affordable, high-tech solution that you can use to monitor electrical systems. PowerMon can be used in RVs, campers, boats, solar systems, off-grid systems, or really anywhere you have a battery that you want to monitor. 

PowerMon is a Bluetooth Low Energy device that measures voltage up to 72V, and current up to 60A using an integrated shunt and temperature. It then calculates power (W), energy (Wh), charge (Ah), battery stat. . .

We developed the PowerMon device because we wanted an affordable, high-tech solution that you can use to monitor electrical systems. PowerMon can be used in RVs, campers, boats, solar systems, off-grid systems, or really anywhere you have a battery that you want to monitor. 

PowerMon is a Bluetooth Low Energy device that measures voltage up to 72V, and current up to 60A using an integrated shunt and temperature. It then calculates power (W), energy (Wh), charge (Ah), battery state-of-charge (SOC %), and estimated time left on the battery. PowerMon keeps track of various statistics: minimum and maximum voltage, current, temperature, battery SOC, the total charged Ah, total discharged Ah, and much more. If you need to measure current higher than 60A (internal shunt rating), an external shunt can be used. 

It doesn't stop here! PowerMon can drive an external relay (or SSR - Solid State Relay). You can use PowerMon as a low voltage disconnect, high voltage disconnect, over-current disconnect, temperature controller, LiFePO4 battery charge manager, as a timer device, as a remote ON/OFF switch, or for automatic generator control. 

A very important feature of PowerMon is that it logs the data for up to 3 years in internal memory (as opposed to other similar products on the market). This means that you don't need to have a mobile device permanently connected to the battery monitor. Whenever you connect to PowerMon, the mobile app will download the data logs from the device. 

Using the PowerMon app or the newer PowerMonX app you can view the measured data in real-time, the statistics, download the log data and visualize it as a chart, configure the device or even update the firmware in the device when new versions become available. 

The small form factor and ease of installation make PowerMon ideal for quickly adding smarts to any existing electrical system. Bluetooth frees you from the need to wire your RV, camper, or boat. PowerMon offers a bonus second voltage input that you can use to monitor a starter battery or maybe the voltage coming from your solar panels. 

Remotely monitoring DC circuit parameters has never been easier!

    Review

    Very valuable and helpful information to have on my trailer as I boondock several times a year. The only negative I have is that after a little more than 2 years it started giving me bad data. I suspect the weather had an impact. I replaced the previous one with this one and all is as it should be. I have enclosed this unit in a plastic electrical junction box for protection from the elements.

    PowerMon Bluetooth battery monitor.

    I’m a little slow catching onto some of the features. The unit seems to work fine. I’ve found the manual a little lacking on the data logging, resetting statistics, or just setting the time. I would describe my issues as how to do stuff. One of the reasons I bought it was for the relay control. Overall I like it and would recommend it.

    This it the device I have been waiting for

    I have tried different Bluetooth battery system monitors and this is the first one I have used that does proper data logging, now I can see the history of how my system has been performing and not just while I have the app open. It's working perfectly off an existing shunt and the Bluetooth range is great

    Great tool

    Bought this primarily for its data logging capabilities. It works great for that application. The unit is incredibly compact and full of features. Also, great tech support.
