Pursuit excellence and realize our dreams. Hubei Bluelight Science&Technology Development Co., Ltd have always advanced in the forefront of science and technology, and actively developed the international market with research and development new products continuously, which is first high power Solar lamp controller as widespread at home and abroad. It’s a long-awaited for appearing in our eyes now, WELLSEE Solar lamp controller 20A-60A, dimmer solar lamp controller 20A-60A, MPPT dimmer solar lamp controller 20A-60A series are on sale in October 2009 . These series has filled gaps in the photovoltaic industry, which deserved rivals’ more admiration on WELLSEE.
WELLSEE solar lamp controller has new high-power series of products as WS-L30, WS-L60. They are working under 2880W solar photovoltaic lighting systems, which is the coordination of solar panels, batteries, lights work, and the key component in the photovoltaic system. This series are divided into 12V, 24V antomatic series and 48V series, with using microcomputer (CPU) control technique,selection of the most advanced power devices, simple and clear LED display, equipment operational status easily and adapting to rough natural environment such as cold, heat, humidity.etc.With intelligent temperature compensation function and efficient PWM battery charging mode ensure that work at the best rechargeable and discharge status, and avoid the battery “overcharge and over discharge” so as to greatly extend the battery life. One-button operation, easy use, excellent performance and reliable quality.
WELLSEE dimmer solar lamp controller has new high-power series of products as WS-AL30, WS-AL60. They are working under 1440W solar photovoltaic lighting systems, intelligent light sensing the strength of the outside world. They could automatically open the lamp at dark which dim light given after half an hour automatically and then be converted to light, as up to setting time or day break be into dawn. Bright light time can be setting at will. They could be designed as customers’ demands for variety energy-saving dimming mode to achieve different degrees energy-saving. The series adopt PWM dimming technology to adjust LED lights, which can match variety tunable optical constant current source work. Having advantages such as low cost, simple circuit, easy maintenance, efficiency energy, reducing inrush current, higher power factor could save energy up to 35% comparing with ordinary lamp controller. It will promote solar energy LED lights applying popular at every place.
WELLSEE solar MPPT dimmer lamp controller has not only basic function but increasing the MPPT function. It could adjust solar panels operating voltage daytime making that solar panels always work at the VA the largest characteristic curve power point under full-day and full-climate. PV module efficiency can be increased by 30% comparing with ordinary solar lamp controller. The series include WS-AL MPPT 30; WS-AL MPPT 60. It could be used under 2880W solar photovoltaic lighting system, and is divided into 12V, 24V automatic identification series and 48V series. All intelligent PWM dimming energy saving could be up to more than 40% to achieve the energy saving effect.The series are also responsible for battery charge and discharge management.When the battery voltage is low, the lights automatically shut down to protect battery; and the battery is full into PWM float state automatically. As it’s at dark , it will close charging circuit to prevent battery discharge through the solar panels for extending battery life greatly. PWM battery charging function can also be activated to avoid sulfide crystals, but also prevents the battery water loss, thus helping protect the battery.
WELLSEE have passed CE and RoHS certifications. The products are well sold in all the parts of our country and many countries, such as Europe, America, Africa, Asia etc. Adhering to business philosophy "quality best, reputation advanced", launching full-service as "10 points ".We promise that we are to be honest, efficient and effective through pre-sales, sales, after-sales.
