14 circuits with battery monitoring on an aluminum or steel vessel? The STV 234-2p is the two-pole version of the STV 236 – galvanic isolation protects your metal hull from stray current corrosion, with the same range of functions.
The Battery Tank Monitor BTM
Shows you battery voltage, charge status, and tank levels in real time – centrally instead of across multiple individual displays.
Model Variants
- STV 234-2p – equipped with the Battery Tank Monitor BTM
- STV 254-2p – equipped with the System Monitor PSM2 (full P-Bus monitoring instead of just battery/tank data)
