REFA L

OFF-GRID SOLAR LIGHTING WITHOUT CABLING & LANDSCAPING COSTS

REFA-L is a convenient and cost-effective solution for off-grid outdoor lighting applications. The integrated solar powered system is grid-independent and can be easily moved anywhere it is required.

All energy from the sun is stored in lithium battery packs which provides total freedom from electricity bills, uncontrolled grid power fluctuations and blackouts. Low or even negligible maintenance costs, zero carbon emission and zero ongoing energy costs makes REFA-L model suitable for energy-efficient smart cities.

The REFA-L have been specifically designed for parks, gardens, sidewalks, cyclepaths and public areas. It provides safe and sustainable LED outdoor lighting at nights as well as in emergencies like power outages, disasters and earthquakes.

REFA-L can be carried even by one person safely with its lightweight aluminum structure

All-in-one Integrated design of REFA-L model provides high energy conversion efficiency by combining the LED module, LED driver, solar panel, lithium battery, intelligent controller and communication unit in one setting.

NO TRENCHING
WITHOUT CABLING
MAINTENANCE FREE
NO BILLS FOR ELECTRICITY

REFA-L requires no cabling, trenching, or grid connection which provides significant cost savings and environmental benefits.

SUITABLE FOR IoT APPS WITH DIFFERENT SENSOR GROUPS

REFA-L designed to work with different types of sensors which collect, store and transfer data to the servers with GPRS connection. REFA-L uses solar energy as the only power source for data collection and communication.

HIGH QUALITY AND TECHNOLOGY

REFA-L is the outcome of our commitment to continuous R&D and innovation culture. With our know-how and dedicated team of engineers, we develop and deliver unique solutions with careful consideration of both function and aesthetics in our production plant based in Istanbul, Turkey.

REFA-L uses high-performance monocrystalline photovoltaic modules for the highest possible energy yields. Our high-quality solar panels can exceed 22% efficiency and integrated intelligent controller based on the MPPT algorithm reaches the energy conversion efficiency of up to 97.4%.

%100 Green Energy, Zero Carbon Emission

Solar-powered REFA-L contributes to the reduction of carbon-emissions.

WIRELESS COMMUNICATION OPTIONS

Remote management system allows you to conveniently manage and monitor REFA-L with its simple mobile application through wireless communication options (Bluetooth, Wi-Fi, GPRS). Flexible communication hardware also makes it easy to implement additional functions such as WiFi hotspots or various sensors.

REFA-L can be the backbone of smart cities by integrating wireless connectivity extensions.

Luminaire lighting levels of REFA-L is dimmable between 1%-100% by using mobile application. Optionally, REFA-L can store 24 hours’ log information for 2 years.

GENERATION & CONSUMPTION OF ENERGY AT THE SAME UNIT

REFA-L generates electricity from solar energy during the day and stores it in a battery system. During the night, the energy stored in the battery is used to power the LED luminaires. Thus, Solar LED Lighting system act as a fully independent and autonomous unit utilizing %100 renewable energy.

NEW GENERATION- LONG LIFE LITHIUM BATTERIES

REFA-L uses lithium battery packs as an energy storage system with 3,000 charge-discharge cycles at 100% DOD. Our advanced lithium batteries can withstand extreme weather conditions with high tolerance to temperature changes. They also have long cycle life with a lifespan of up to 10 years.

New generation lithium based batteries offer significant advantages, including high charge-discharge efficiency, light-weight, capability to deep-cycle, high energy density and low maintenance. They have a working temperature ranging from -20ᵒC to +60ᵒC which can also be expanded to -40ᵒC thanks to our advanced thermal management technology.

Our efficient battery management system is designed to monitor and control the cell balancing actively in order to optimize the charging efficiency and maximize the battery life.

COLOR OPTIONS

We can meet your specific color requirements by using the RAL color system. Any color can be applied to our models with pre-defined RAL code.

DIMENSIONS:

REFA-L has two standard pole height options as 3m and 3.5meters. However, we can offer custom-designed pole height options specific to your project requirements.
