Powerful and safe - no electrical grid required. Recommended for average sunshine regions, like Europe, southern Russia, New Zealand. 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 are made of stainless steel. This solar light is maintenance free - only the solar panel should be cleaned occasionally with water. Our systems are provided with serial numbers, wich can be validated to protect against malicious copies. General specifications: Lighted area: aprx. 18 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 Low safe voltage Approvals: CE, RoHS, WEEE 20 years sparepart supply ability. Lamp specifications: LED Lamp: SMD chipset LED power: 18W Energy efficiency class: A Light colour: 4000K neutral white (on request 5000K cold white or 3000K warm white). No uv-radiation for reduced insects attraction LED efficiency: > 160 lm/w Lamp efficiacy: > 140 lm/w Luminous flux: 2500 Lm Central illumination: > 8 Lux (at 5m pole height) Life time: Aprx. 100000 h Casing: Rigid aluminium die-cast. Seawater and thunderstorm-proof. Protection degree: IP66 5 years guarantee System controler specifications: Programmable smart processor charge controler. Wireless remote control 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 5 years guarantee Solar panel specifications: High efficient monocrystalline silicone (tempered glass encapsulated, hailproof) This modern cell technology has a high degree of efficiency and allows charging also at cloudy weather. Efficiency: > 16% Power: 100Wp 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: High performance lithium iron phosphate accumulator LiFePo4 Battery voltage: 12V maintenance-free, longlife. For solar cycle operation Lifetime 6 - 10 years / 20°C Function even at low temperatures. For sufficient reliability in autumn or winter, we strongly recommend our extension sets. Autonomy time in overcast weather (with fully charged battery): a) Basic version: 40 hours (4 days) b) with extension set winter: 80 hours (8 days) 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: Steel pole, hot-dip galvanized, Upper height 5 m inground length: 800mm Installation into concrete. With lockable 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. Steel pole. Manual for easy mechanical and electrical setup in english language.
