Stray currents on the hull are one of the most common reasons for corrosion on metal ships – and often remain unnoticed until the damage is visible. The STV ISO makes checking routine: a two-pole control button with two LEDs shows you at a glance whether the hull is voltage-free.
Why this is not an optional extra
Unlike the other Series 200 panels, this is not about electrical circuits, but about preventive corrosion protection – an inexpensive addition to any onboard power system on metal ships, regardless of which main panel you have chosen.

Frequently Asked Questions
How often should I check?
Regularly, ideally with every longer change of berth or at fixed intervals – stray currents can be caused by neighboring boats or shore power systems.
What does it mean if not both LEDs are lit?
This indicates a voltage potential on the hull – the cause should be checked promptly to prevent corrosion.

FAQ
Yes, this is possible. For this, the required fuse size per circuit must be specified when ordering the switch panel.
Yes, before each switchboard, a main fuse must be integrated into the supply line to the switchboard near the battery.
Yes, all common sensors used in the marine and automotive sectors can be connected.
