SensMax Solar power system SPS20

The SensMax SPS20 Solar Power System is an independent solar-powered energy unit engineered to power outdoor pedestrian and bicycle counting radar sensors in off-grid locations. Custom-designed for the SensMax TAC-B 3D-WP and TAC-B 4G outdoor radar sensors, the SPS20 enables continuous, non-stop flow monitoring in remote environments where electrical wiring is unavailable or cost-prohibitive.

How the System Works

The SPS20 captures solar energy via an integrated photovoltaic panel and routes it through an intelligent charge controller into a high-capacity LiFePO4 rechargeable battery. The controller safeguards the battery against deep discharge and overcharging while delivering stable power to the counting radar.

During prolonged overcast conditions or night operation, the onboard LiFePO4 battery delivers 65 to 85 hours of continuous autonomy (depending on sensor settings), maintaining unbroken data collection regardless of weather or season.

Key Features & Technical Performance

• Integrated "All-in-One" Architecture: Combines solar panel, smart charge controller, and LiFePO4 battery inside a single compact mounting assembly.

• IP67 All-Weather Durability: Enclosed in a rugged, waterproof housing built to withstand severe rain, snow, extreme temperatures, and dust.

• Plug-and-Play Installation: Pre-wired internal components simplify field mounting on poles or walls without requiring specialized electrical crew work.

• Extended Battery Autonomy: Operates for 65 to 85 hours without direct sunlight.

• Zero Infrastructure Overhead: Eliminates expensive trenching, cable laying, or electrical grid connection permits.

• 100% Eco-Friendly Power: Runs on renewable energy to support zero-carbon municipal and environmental monitoring initiatives.

Applications & Strategic Use Cases

• Smart City Infrastructure: Track pedestrian and cyclist density across bike lanes, plazas, and transit corridors to guide urban planning investments.

• National Parks & Mountain Trails: Monitor visitor flow in protected natural areas without invasive wiring or disturbing local wildlife.

• Public Events & Outdoor Festivals: Temporarily deploy counting sensors at concerts, fairs, or sporting events without running noisy generators.

• Tourist Ports & Cruise Terminals: Analyze passenger transit flows to optimize logistics, security staffing, and site management.

• Urban Parks & Recreation: Measure utilization rates across sports fields, playgrounds, and botanical gardens to justify maintenance budgets and grant funding.
