Rodent Repeller Viano Battery Powered Ultrasonic Mice Rats Martens 200m Range IP65
Description
VIANO OB-02 ultrasonic repeller for martens, mice and rats – battery-powered, IP65
VIANO OB-02 repeller is a professional ultrasonic device that effectively protects photovoltaic installations, lofts, garages and outbuildings from martens, mice, rats and weasels. Thanks to battery power and IP65 protection class, it works perfectly wherever there is no access to 230V mains supply.

Why choose it? Martens and rodents pose a serious threat to PV installations – they chew through cable insulation, damage seals and build nests under panels. VIANO OB-02 emits ultrasound in the 16–65 kHz range with automatic frequency variation, preventing pests from becoming accustomed to the sound.
Key advantages
- Wide coverage: effective area up to 2500 m², 120° emission angle
- Wireless operation: powered by 4× LR6 batteries (DURACELL included), up to 3 months runtime
- Year-round operation: temperature range from -30°C to +70°C
- Weatherproof: IP65 protection class – resistant to rain, snow and dust
- Quick installation: built-in neodymium magnet for mounting on metal surfaces
Two Ø50 mm piezoelectric speakers made of brass ensure high power and durability. Protective grilles shield the transducers from mechanical damage, whilst silicone seals and a switch cap guarantee complete housing integrity.
Installation examples



The device installs in seconds – simply attach the rear of the housing to a metal surface (gutter, PV mounting structure, fence, shelving). It can also be screwed through the corner holes in the housing.
