NEXTGEN’s Solar Garden Lights are compact, mini solar lighting systems that generate and utilize their own power, harnessing the energy of the sun during the day and using it to provide lighting at night. Each light uses its own solar photovoltaic (PV) module, mounted on the lighting structure, to convert solar into electrical energy and store it in a rechargeable battery. The battery can then be used to power a florescent or LED lamp to provide lighting at night. The lamp is switched on through an automatic controller that senses ambient light conditions and turns the light on at dusk and off at dawn. Since each light generates and utilizes its own electricity, these fixtures require no wiring for installation – making them an extremely quick and flexible lighting option for outdoor spaces without the need for conventional electricity Solar Garden Lights Features Easy to install No wiring required Charging by premium quality solar PV modules Dusk to dawn controller for automatic switch ON / OFF Attractive, weather proof luminaries Adequate protections and indications SMF (sealed maintenance free) battery High bright LEDs ensure adequate lighting and long performance without the need for regular replacements NEXTGEN's Solar Garden Lights offer a safe and cost effective solution for lighting your garden. These lights require no electrical wiring, are powered by DC electricity generated from sunlight and can be easily relocated should you decide to redesign your garden. Best of all, NEXTGEN's Solar Garden Lights do not require the burning of fossil fuels and the emission of carbon dioxide (CO2) and other pollutants associated with the generation of conventional electricity.

A solar charge controller limits the rate at which charge is added to or drawn from electric batteries, protecting batteries against overcharging from solar panels as well as complete draining or ‘deep discharge’, which can reduce battery performance and lifespan or pose a safety risk. A Solar Charge Controller is needed in virtually every solar power system that utilizes batteries. A basic charge controller simply monitors battery voltage and stops the charging when the battery voltage rises to a certain level. Modern charge controllers slowly lower the amount of power applied to the battery as it gets closer and closer to full charge. The NEXTGEN Solar Charge Controller uses sophisticated PWM (pulse width modulation) technology to adjust charging rates, as the battery gets closer to full charge, allowing for uniform charging and improving battery performance and life.   Features Multi-stage PWM charge control to improve battery performance and life Integrated temperature compensation with external temperature sensor Low power load controller and PWM solar charger in a single unit Overload / short circuit / reverse flow and battery reverse polarity protections with status display Intelligent microprocessor control Adjustable charging and discharging control parameters Optional dawn / dusk operation with timer LCD monitor for parameter display and communication interface with PC for data logging Enables optimum utilization of solar power Low PV to battery drop Easy installation, simple handling Robust, inexpensive, energy efficient, suitable for rural / urban solar power systems
