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.

Eltek Valere -- one-stop source for telecom solar solution
DRAMMEN, NORWAY: Eltek Valere has partnered with key solar component vendors to become a one-stop-shop for carriers investing in green and sustainable power solutions for wireless and broadband remote sites.
Eltek Valere’s Global Sourcing Team (GST) has negotiated supply agreements with global vendors of solar panels, cyclic batteries and tracking systems. With peripheral hardware being sourced locally, Eltek Valere with its leading products and this ecosystem of partners can deliver complete solar and hybrid power solutions to both existing and new networks globally.
The announcement comes in conjunction with the release of the company’s new Flatpack2 HE Solar Converter providing Maximum Power Point Tracking (MPPT) to optimize energy utilization of the solar panels and galvanic isolation for improved safety and reliability. The solar converter is based on Eltek Valere’s High Efficiency (HE) technology, delivering 96 percent efficiency and cutting power loss and heat generation in half compared to conventional technology.
The objective of a solar power installation is reduced total cost of ownership by cutting energy-related operating and maintenance costs, increased network reliability and reach as well as improved environmental performance. This initiative from Eltek Valere smoothes out the logistics for carriers while giving them a system optimized for their needs.
“The technology is available to make solar power an effective energy source for telecom applications in remote areas with limited or no access to electricity grid,” said Morten Schoyen, Eltek Valere Chief Marketing Officer. “We’re taking a major step toward bringing this environmental consciousness into global telecommunications by providing a complete and viable solar or hybrid solution that service providers can implement quickly and that makes financial sense.”
