Sandstorm-proof and seawater resistant PV street lighting fixture, with bright LED Lamp. Recommended for sunny regions, like Africa, desert countries, South America, Philipines. High brightness corresponds to 40 watt fluorescent light. Very long maintenance-free system lifespan, by use of efficient LED lamps and electronic 24V-60V PWM driver. Microprocessor system control for lighting and charging. Pole and brackets are hot dip galvanized (on surcharge with a UV-resistant painting). The screws consist of stainless steel. This solar light is maintenance free - only the solar panel should be cleaned occasionally with water. Each system has an unique serial number, wich can be validated to protect against malicious copies. General specifications: Lighted area: aprx. 20 x 8m Distance from pole to pole: 18 - 25 meters Ambient temperature: -20°C ~ +55°C (extended temperature range -35°C ~ +65°C available on request) Max. direct sunshine temperature: 85° C / 176 F degree Protection class: III SELV Low safe voltage Approvals: CE, RoHS, WEEE 20 years sparepart supply ability. Lamp specifications: Light colour: 4000K neutral white (on request 5000K cold white or 3000K warm white). No uv-radiation for reduced insects attraction LED efficiency: > 145 lm/w Lamp efficiacy: > 135 lm/w Luminous flux: 2500 Lm Central illumination: > 8 Lux (at 6m pole height) Life time: Aprx. 100000 h Casing: Rigid aluminium die-cast. Seawater and thunderstorm-proof. Adjustable inclination: 0 / 5 / 10/ 15 degr Arm length: 300mm (on request, we supply with 1 meter arm) Protection degree: IP66 Impact resistance: IK08 Guarantee: 5 years System controler specifications: Programmable Processor charge controler. Wireless remote programmer as acessory available. Metering memory for actual and last days system status. Automatic lamp start at sunset and turn-off by dawn. (Level adjustable) Timer-dimmer: Full power at start-up, automatic dimming at late night and full power again in the early morning, for more safety at low battery capacity. All functions are pre-programmed by us, for the project and to customer specifications, so that the lamp is ready for operation immediately after installation. Temperature feeded battery charging for extended battery life. Overcharge and deep discharge protection for the battery. Reverse polarity and electronic short circuit protection. Additional electric fuse Protection degree: IP66 Guarantee: 5 years Solar panel specifications: High efficient monocrystalline silicone (tempered glass encapsulated, sandstorm proof) This modern cell technology has a high degree of efficiency and allows charging also at cloudy weather. Efficiency: > 19% Power: 60Wp Life expectancy: aprx. 25 years 20 years 80% power guaranty * 10 years 90% power guaranty * * excepted is the complete failing (3 years guarantee) Battery storage: Battery type: Li iron phosphate accumulator LiFePo4 Battery voltage: 12V maintenance-free, longlife. For solar cycle charge operation Lifetime 8 - 10 years / 20°C Function even at low temperatures. For sufficient reliability in autumn or winter, we strongly recommend our extension sets. Autonomy time: 35 hours (3 days) at absolutely no sunshine (with fully charged battery and smart dimming) or 13.3 hours at 100% continuous power. The new emergency lighting function ensures lighting even during low battery charging during very long periods of bad weather, but with reduced luminosity. The battery is mounted inside the mast, behind the lockable door. Pole is not included: Recommended height: 4m - 6m With service door, for easy acces to the controller. Including following components: LED light fixture with arm and pole mount bracket. LiFePo4 battery, Solar module with frame and bracket for adjustable top-mount. System controler. Manual for easy mechanical and electrical setup in english language. Other languages on request. Complete pre-wired unit without pole.
