VIA 2025

One panel. Complete control. No technical skill needed.

A complete digital switching and battery monitoring system for campervans and RVs.

An all-in-one solution that lets you travel further and worry less. Monitor your batteries, tanks, temperature, solar, fridge and more, while enjoying smart control and power distribution in one simple panel.

Combining two worlds together: beauty and utility

We’re exceeding the old-fashioned belief that what is beautiful can’t be smart. It’s time to say goodbye to outdated design and say hello to sleek, elegant, and contemporary design that fuses perfectly with the interior of your campervan, caravan, or RV.

The VIA control panel has everything a modern device should have – an anodized aluminum case, optically bonded high-resolution IPS screen with polarizing filter, and automatic illumination of display and buttons.

Know before it shows!

Your battery, never a mystery

From your service to your engine battery, VIA makes it crystal clear. Real-time flow, charge, and runtime. No guessing, just the most accurate monitoring yet.

You will never again run out mid-shower

VIA keeps an eye on fresh, waste, and fuel tanks, so you’ve always got water to use, fuel to drive, and no surprises along the way!

Stay level, stay safe, stay balanced

With VIA’s inclinometer you’ll always find the sweet spot – showing pitch and roll in real time, so you can park level, sleep well, and keep life in the van balanced.

Push the right button!

Teamwork makes the dream work

The VIA control panel comes together with the SPDU52 12V power distribution unit. It’s a versatile module, equipped with 6 switching channels distributed across 12 fuses, a 50 A shunt for the service battery, 40 A shunt for the wall charger, and a 16 A shunt for solar.

It also provides power for other external modules and shunts. Further, it is completely compatible with all the existing expansion modules.

As a backup, the system has a manual override option in case the panel is not working for some reason.

With additional modules you can connect it to up to 6 battery banks, 24 shunts, 10 temperature sensors, 14 tank level sensors, and one inclinometer sensor. That’s a full house, right?

Be warned when the battery state, water level, or temperature is too low or too high

Choose your device, the high and the low thresholds for alarm, and alarm duration and delay.

The ST107 tank level and voltage module and the SCQ25, SCQ50, SCQ25T have an integrated programmable 12 V alarm signal relay that you can configure to output a signal of 1 A in the event of an alarm.

View all data on your phone

Turn on your panel’s Wi-Fi Direct (localhost) and view live data.

Light switches with programmable dimmers

Wherever the road takes you, you still need that feeling of being at home. If you want to give your camper a nice, homely feeling, consider adding digital light switches with integrated dimmers.

Our anodized aluminum light switches have programmable dimmers, meaning you can set their location. This allows you to control the same light with two or more switches, while only one switch needs to be connected to the light.
