FAQ


How often should the buoy batteries be replaced?
Batteries should be replaced every 3-5 years, if the charge ever falls below 10.5V, or as needed due to performance.

Is it safe to lift the buoy from a single eye nut?
Yes, a single topside eye nut can support the weight of a buoy without load attached. Care should always be taken to avoid damaging the solar panels, topside sensor mounts and sensors connected to the instrument cage when lifting and moving a buoy.

What is the minimum recommended ballast weight?
Ballast weight may vary depending on environmental conditions and topside weight added. Recommended minimum weights are available in the table at the link below. Some experimentation may be needed to ensure a buoy is stable in the water.

What are the data buoy storage requirements?
Data loggers and all accessories (beacons, sensors, etc.) should be powered off, sensor connection ports should be covered, and the buoy should be placed in a dry environment kept above freezing at a minimum. Buoy batteries should be periodically charged during long-term storage.

What are the battery capacities in CB-Series Data Buoys?
NexSens data buoys will have differing battery capacities depending on the buoy size and integrated battery harness. Multiple batteries can be wired in parallel to maintain the 12VDC nominal voltage while adding more Amp hour capacity for systems with higher overall current draw.

What are the NexSens solar panel specifications?
NexSens provides multiple solar power options for powering land-based and buoy-based environmental monitoring systems. Learn more about the single-panel manufacturer specifications to accommodate your system.
