Robust and reliable photovoltaic lighting system with multiple LED lamps - no power connection required. High luminous intensity thanks to state-of-the-art SMD LED in combination with an electronic 12V-60V DC PWM driver. Very long, maintenance-free luminaire operation due to special design features. Microprocessor lighting control in continuous operation, only at night or with motion detection. The PV modules are fastened near the tunnel area, outdoors. For example, on a steel mast at the tunnel entrance or exit. All mounts and fixings are hot-dip galvanized (on request additionally scratch-resistant and UV-resistant lacquered). Construction, production and quality management in Germany. The lighting system is maintenance-free - (only the solar panel should occasionally be cleaned with water). General technical data: Tunnel length: approx. 25m - 40m Recommended distance between luminaires: 3 - 6 meters Ambient temperature: -20 ° C ~ + 55 ° C (extension -35 ° C ~ + 65 ° C possible on request) Protection class: III Protective extra-low voltage Test mark: CE, RoHS, WEEE 20-year availability guarantee for replacement parts. Lamp head specification: Impact-proof LED luminaires - number depending on tunnel length and light requirement LED lamp: SMD chipset LED power: 6 - 20W per light point Energy rating: A +++ Light color: 4000K natural white (on special order also 3000K warm white or 5000K cool white). Luminous efficiency: > 134 lm / w Central illuminance: > 3 - 20 lux (as required) LED life about 80,000 hours Protection class: IP66 (protected against water and storm). Warranty: 5 years Light Control: Smart microprocessor control with infrared programming option. Reading the current operating status with storage of the measurement data of all components of the last days. Automatic switch on at sunset and switch off at sunrise. (Switching level adjustable) Adjustable dimming during the late night and full power in the morning to extend the duration of the light in bad weather. Operating time / duration (please specify when ordering) You have the option from dawn to choose 4 consecutive time blocks with 1-15 hours duration and different light intensity of 10-100%. Example 1: Night reduction with shutdown and morning light From dusk 4 hours with 100%, then 2 hours with 50%, then 3 hours off (0%) and early in the morning 5 hours with 100% Example 2: Night shutdown 4 hours 100%, 4 hours Midnight 0%, 5 hours 100% Example 3: Motion detector At night with 10%, upon detection of a person 100% light for one minute. In addition, the charge controller is equipped with a Smart Power function, which allows automatic dimming at night depending on the battery charge level. If the battery voltage drops below 50%, the lamp is automatically dimmed to 50%, this process is decreasing until the deep discharge protection starts. This setting allows safe operation even on the faint days in winter. We will gladly help you to decide on the right presettings. All functions are preprogrammed by us free of charge, depending on the project and customer request, so that the luminaire is ready for use immediately after installation. To change the settings, you need the S-SOLS29 remote control. Temperature-optimized battery charge and trickle charge to protect the batteries. Overvoltage and deep discharge protection for battery. Reverse polarity and short circuit protection. Additional fuse Protection: IP66 Warranty: 5 years Solar module specifications: Monocrystalline silicon with very high efficiency tempered protective glass, hailproof This high quality module technology also ensures charge in overcast skies. On dark days in winter, the recharging is limited, the light duration is thus reduced. Efficiency:> 17% Power: 300Wp (without extension) Life expectancy: approx. 25 years Performance Guarantee * 20 years 80% / 10 years 90% * except in the case of mechanical impact Battery storage: Battery Type: Lead Gel 12V, maintenance-free, longlife. For solar cycle operation Life span: approx. 8-10 years / 20 ° C Function even at low temperatures. For an extra charge: Lithium-ion LiFePo4 battery For sufficient reliability in autumn or winter, we strongly recommend our extension sets. Self-sufficient operating time in overcast weather (with fully charged battery): a) Basic version: 2 days (48 hours) b) with extension set autumn: 3 days (60 hours) c) with extension set winter: 4 days (80 hours) The new emergency lighting function ensures the lighting even with low battery charge in very long periods of bad weather, but with reduced luminosity. Battery box: The batteries are placed in the ground to protect against temperature fluctuations (longer life). Stable plastic box IP67 (non-walkable version) with cable protective hose, stainless steel reinforced: Dimensions: L 496 x W 280 x H 270mm optional ABS housing IP66 (walk-over model): Dimensions: L 550 x W 550 x H 480mm Delivery disassembled with following components: LED light bars for wall and ceiling mounting. Energy storage Solar module with stable, screw-down mast mounting. Luminaire control (with mounting plate for commercial light poles). Battery ground installation box, Illustrated assembly instructions in German or English. Other languages on request. All components are pre-wired or prepared for quick setup. We plan and configure this lighting system according to your specifications. The luminaire pole must be ordered separately (recommended length 4 meters) with a plait diameter of about 108mm
