Robust and reliable photovoltaic street light with LED lamp - no power connection required. Recommended for countries with average solar radiation, such as Europe, southern Russia, New Zealand. Applications: Nature reserves, remote homes, country roads, campsites, bike paths, parks, driveways, farms, highway car parks, park and ride lots, industrial buildings, airfields. Adaptable for other applications, e.g. traffic sign lighting, coastal navigation lights, NEMP HEMP hardened and much more. High luminous intensity due to state-of-the-art SMD LED in combination with dimmable DC PWM driver. The brightness is comparable to an 80W mercury vapour lamp or 50W sodium vapour lamp. Very long, maintenance-free luminaire operation due to special design features. Smart microprocessor luminaire control. Manufacture and quality management in Germany. The solar light is maintenance-free - (only the solar module should be cleaned with water occasionally). General technical data: Illuminated area: Approx. 27 x 10m Recommended mast distance: 20 - 28 metres Ambient temperature: -20°C ~ +55°C (extension -35°C ~ +65°C possible on request) Energy efficiency class A Protection class: III safety extra-low voltage Approval marks: CE, RoHS, WEEE Material: Brackets: Hot-dip galvanised steel (UV-resistant paint available at extra charge). Screws: VA stainless steel. 20-year availability guarantee for spare parts. Luminaire head specification: Robust LED luminaire head made of die-cast aluminium LED lamp: SMD chipset LED power: 35W Light colour 4000K neutral white (on special order also 3000K warm white or 5000K cool white). No UV radiation for reduced insect attraction Luminaire efficiency: > 134 lm/w Luminous flux lumen: 5000 Lm Central illuminance: >15 Lux (6m height) Average luminous intensity: > 8 Lux (6m) LED life: approx. 100,000 hours Protection class: IP66 (water and storm protected). Warranty: 5 years Luminaire control: Smart MPPT microprocessor control with wireless programming option. Readout of 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 late night and full power again in the morning to extend the lighting duration in bad weather. Please specify desired lighting times and night-time dimming when ordering. You have the option of selecting 4 consecutive time blocks from dusk onwards, each lasting 1-15 hours and with varying light intensity from 10-100%. Example 1: From dusk 4 hours with 100%, then 2 hours with 50%, then 3 hours off (0%) and early in the morning 4 hours with 100%. Example 2: 4 hours 100%, 5 hours midnight 0%, 4 hours 100%. Example 3: 4 hours at 100%, then 10 hours (rest of the night) at 50%. In addition, the charge controller is equipped with a Smart Power function that enables automatic dimming during the night depending on the battery charge level. When the battery voltage drops below 50%, the lamp is automatically dimmed to 50%, this process is descending until the deep discharge protection kicks in. This setting enables safe operation even on the low-light days in winter. The charge controller settings are preset by us according to customer requirements. To change the settings, you need the S-SOLS29 remote control. We will be happy to help you decide on the right presettings. All functions are pre-programmed by us free of charge, depending on the project and customer requirements, so that the luminaire is ready for operation immediately after installation. Temperature-optimised battery charging and trickle charging to protect the batteries. Overvoltage and deep discharge protection for battery. Reverse polarity and short circuit protection. Additional fuse. Protection class: IP66 Warranty: 5 years Solar module specifications: Monocrystalline silicon with very high efficiency Tempered protective glass, hail-resistant. This high-quality module technology ensures charging even on overcast days. On dark days in winter, recharging is limited and the lighting duration is thus shortened. Efficiency: > 18 Output: 200Wp (without extension) Life expectancy: approx. 25 years Performance guarantee * 20 years 80% / 10 years 90% * except in case of mechanical impact Battery storage: Battery type: lead-gel 12V maintenance-free, longlife. For solar cycle operation Service life approx. 10 years / 20°C. Function also at low temperatures. For an extra charge: Lithium-ion LiFePo4 battery For sufficient operating safety in autumn or winter, we strongly recommend our extension sets. Autonomous operating time in overcast weather (with fully charged battery): 80 hours The new emergency lighting function ensures lighting even when the battery charge is low during very long periods of bad weather, but with reduced luminosity. Battery box: The batteries sit in the ground to protect against temperature fluctuations (longer life). Sturdy plastic box IP67 ( not walk-in version) with cable protection tube: Dimensions: L 496 x W 280 x H 270mm On request ABS enclosure IP66 (walk-in version): Dimensions: L 550 x W 550 x H 480mm Supplied disassembled with the following components: LED lamp head with pole mount.
