INTERVOLT Inertial Sense Module
The Inertial Sense Module or ISM is a solid-state electronic device developed for use with the interVOLT DCC Pro.
In simple terms the ISM detects movement (from both engine vibration and acceleration) when attached to the vehicle chassis or body. Once the input voltage is within operating range this movement will provide a trigger signal to the DCC Pro and initiate the charging cycle.
This enables the DCC Pro to be operated in Ignition Mode without having to tap into the vehicle manufacturer’s wiring system to obtain a signal. As a result, the whole DCC Pro install becomes totally independent of the vehicle’s electrical system, aside from the common connection of the main battery terminals.

Working perfectly in my Audi Q7 to trigger the ignition wire on my Kings 25A DCDC with solar. 120w solar panel in the roof basket to charge the 120ah Lithium battery that runs the fridge. No messing with the cars wiring 👍🏻👍🏻👍🏻

G’day Stephen, thank you for the feedback that is awesome to hear.

This is the second ISM I’ve bought from JTS12V. The first has been switching the Kings DCDC flawlessly in my Audi Q7 to charge the 120Ah Lithium that runs the fridge. I’m now installing a Renogy DCDC and expect I’ll get a similarly good result while the existing setup will be moved into my Rangie.
