DRAMMEN, NORWAY: Eltek Valere announced a new solar converter that makes solar power an even more viable option for remote wireless cell sites or broadband telecom applications. The company’s new Flatpack2 HE Solar delivers unrivaled performance in terms of energy efficiency, heat loss, solar panel utilization, lightning/surge protection, modularity and reliability.
Four to six solar panels are connected to each Flatpack2 HE Solar converter, which converts the solar power into controlled 48VDC for supply to telecom equipment. The centre of the solution is the advanced Smartpack monitoring and control unit that optimizes the system with regard to battery performance, network management, diesel consumption on hybrid sites as well as controlling additional Flatpack2 HE rectifiers where applicable.
The power output from solar panels varies depending on time of the day, shading effects, weather conditions and seasonal position of the sun. A traditional ‘direct feed’ telecom system typically only utilizes 70% of the panel’s available power output and does not provide isolation between the panels and the telecom equipment.
To reach 100% panel utilization, the Flatpack2 HE Solar converter features maximum power point tracking (MPPT) technology to generate maximum power from the solar panels under all conditions. The converter regularly scans the panels to ensure peak output during changing conditions.
The solar charger is based on Eltek Valere’s High Efficiency (HE) technology, which delivers 96 percent power conversion efficiency across the whole load range. This is the highest power efficiency today and cuts the power conversion losses in half compared to conventional technology –- finally making solar power a green and profitable alternative for the future of communications.
“The features, intelligence and efficiency that we’ve built into the Flatpack2 HE Solar converter makes solar solutions ‘telecom-ready’ and eliminates the obstacles that have kept carriers from rolling it out in their networks. The solution provides an unrivaled technical and commercial solution to expand communication to areas without access to reliable commercial power,” said Morten Schoyen, Eltek Valere chief marketing officer. “We’ve been able to leverage our exclusive HE technology and other key features to help solar power deliver for carriers.”
The Flatpack2 HE Solar converter is suitable for all telecom applications in both autonomous (solar only) or hybrid solar power applications. The converter integrates with Flatpack2 rectifier systems in combination with the advanced Smartpack monitoring and control unit in a unique solution managing the power from all different sources, such as solar, grid and generator.
Galvanic isolation between solar panels and batteries/telecom equipment provides high level of surge protection and reliability.
The Flatpack2 HE Solar converter and corresponding solutions have already been supplied to several carriers and are available from Eltek Valere’s worldwide sales force and offices.

Can we expect exciting times in 2008?
Welcome 2008! May I wish all my readers a very happy and prosperous 2008. Another year's gone past. We have a habit of looking back to see at what happened and what could have been.
A lot has been written already about 2007 and what to expect in 2008. So let's just touch upon some of the events from 2007 and some expectations from 2008.
For India, 2007 was a great year for the semiconductor industry -- first, the Indian government announced the semiconductor policy, followed some months later by the fab policy. Both were tremendous firsts in India's science and technology, and not IT, history. Everyone hopes that the Indian semiconductor industry will take off this year. Eyes are focused on the embedded segment, what with the global semiconductor industry reportedly facing 'an embedded dilemma.'
An issue hitting the EDA industry is that, the cost of designing or developing the embededded software for an SoC actually passed the cost of desgining the SoC itself in 2007. The world needs to avoid this software crisis, and India is well placed to take full advantage and play a major role, given its strength in embedded.
In IT, it's been a mixed sort of a year for Apple, which hit big time with the iPhone, seemed not to make waves with either the Safari browser or the Leopard OS. Microsoft had the Vista OS, but then, Vista didn't exactly warm the hearts of users or those who wished to upgrade their OS, including yours truly. Maybe, 2008 would ring in better times for Vista.
While on browsers, Firefox has gained lot of ground. However, by the end of 2007 came the news that the Netscape Web browser -- which started it all -- would soon be confined to history.
Netscape Navigator was the world's first commercial Web browser and launch pad of the Internet boom. It will be taken off on February 1, 2008, after a 13-year run. Time Warner's AOL, its current owner, has reportedly decided to kill further development and technical support to focus on growing the company as an advertising business. The first version of Netscape had come out in late 1994.
In gaming, there are admirers of Wii, PS3 and Xbox 360, and will remain the same. Which one of these gaming consoles will reign supreme, eventually, is difficult to predict.
In consumer electronics, lines are surely blurring between portable media players (PMPs) and portable navigation devices. Also, it would be interesting to see how digital photo frames survive 2008. A reported tight supply, especially for seven-inch models, has led to some makers in Asia either postponing mass production or extending lead times. Surely, makers cannot add more entertainment functions in smaller screen models, to keep costs down.
In the security products market, IP cameras and video servers should have a better year, with more emphasis now on video surveillance. In fact, some friends have been querying me as well regarding their potential.
On components, we can hope to see more growth for solid polymer capacitors in 2008, and among PCBs some fabricators should start manufacturing high-density interconnect (HDI) PCBs this year.
In wireless, we should witness TD-SCDMA in operation prior to the Beijing Olympic Games. Backers would like to see TD-SCDMA succeed, given the effort Datang-Siemens has made on the technology, as also the Chinese government, which issued spectrum for TD-SCDMA nearly five years ago!
Let's all welcome 2008 and look forward to more exciting things happening.
