10 circuits plus detailed battery monitoring plus charging capability – all on one panel? The STV 232 combines exactly that: 10 fused circuits, the BTM2 battery/tank monitor and an integrated USB-C/A plus DC socket.
The BTM2 Battery/Tank Monitor
The BTM2 displays battery voltage, charge status, charge/discharge current, and tank levels in real time on a 3.5" color touchscreen and can be integrated directly into your onboard network thanks to NMEA 2000.
Compared to the STV 250 and STV 270
If you prefer full P-Bus system monitoring, the STV 250 (PSM3) or STV 270 (PSL, larger display) is the more future-proof choice – both also with 10 circuits and charging capability.

Frequently Asked Questions
What does the BTM2 display?
Battery voltage, charge status, charge/discharge current, and tank levels – in real time on a 3.5" touchscreen.
Should I choose PSM3 or PSL instead?
If you plan to significantly expand your P-Bus system later, yes – otherwise, the BTM2 already covers the most common requirements.
