Use PowerMon In

RVs

Probably our biggest market. Any RV has at least one battery. You should know how much power you have left!

Boats

Kinda like an RV but for the aquatic specimens. They have big batteries, solar panels, ACs and water makers.

Smart Home

Do you have solar? Maybe you should. You should also use a PowerMon to check how much power you're generating.

Solar Energy

From the smallest solar system (20W) to the largest... PowerMon can find it's way in your system.

Automation

Control lights, water pumps, generators, or irrigation using PowerMon's built-in timers.

01

PowerMon is a battery monitor

It can measure voltage up to 65V and current up to 60A using an integrated shunt. It then calculates power (W), energy (Wh), charge (Ah), battery state-of-charge (SOC %), and estimated time left until the battery is fully discharged.

02

And it's Bluetooth

PowerMon is equipped with a Bluetooth LE (Low Energy) radio. You can use your cellphone or tablet to connect to it and check what your equipment is doing. Install PowerMon in a battery box or equipment bay and forget about it.

03

It has an integrated 500A shunt

PowerMon can monitor currents up to 500A using the integrated shunt. It should be installed on the positive side of the battery to avoid any interference with the ground wiring.

04

And it can drive an external relay

The capability of driving a relay opens up a lot of possibilities. You can use either a mechanical relay or a solid-state relay for various applications, such as a remote ON/OFF switch, battery protection, or even starting a generator.

05

Many protection features

Don't leave your expensive batteries unprotected!

Paired with a relay, PowerMon can serve various functions, including acting as a low-voltage disconnect, high-voltage disconnect, over-current disconnect, generator controller, or a general-purpose timer. Need to control the relay based on temperature? PowerMon can do that as well! And by the way, we also offer timer functionality.

06

Logs the data for up to 3 years

Record what your battery is doing! PowerMon can log data for up to 3 years in internal memory, unlike other similar products on the market that store it inside the mobile app. This means 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. PowerMon records voltage, current, power, temperature, and state-of-charge, and you can adjust the recording frequency from once a second to once a minute.

07

And can even start your generator

Enable the generator control feature, and PowerMon can start your generator when the voltage or state-of-charge drops below a specified threshold.

08

Very Low Power

PowerMon does it all while sipping on only ~6mA. The battery self discharge is higher than what PowerMon needs to function.

09

But if Bluetooth only is not enough

We have a screen to go with it too. PowerMon-D4 is a 4.3" color touchscreen that connects to the PowerMon via Bluetooth. It also has WiFi, and we plan to add support for cloud connectivity in the future.
