Stäubli Electrical Connectors shows a range of products for solar, storage connection at Intersolar 2018

Stabuli connectors

A small but mighty connector is powering the march toward clean, renewable energy and saving our energy grid from substantial power loss in the process. Stäubli Electrical Connectors (formerly Multi-Contact) has amassed more than 20 years of experience in the photovoltaics industry. During this time, more than 203 GW of PV power, or more than 50 percent of the PV power worldwide, has been successfully installed using more than 1 billion original MC4 connectors from Stäubli Electrical Connectors.

The company is showcasing a broad array of its solutions for energy storage, connection and transfer at Intersolar North America (booth #8711) in San Francisco this week.

“Investing in high-quality components will improve the life and efficiency of a project, significantly increasing the project’s return on investment,” said Christian España, Sales and Marketing Manager at Stäubli Electrical Connectors. “We call this idea ‘bankability,’ which means a small upfront investment will save money in the long run, and also improve safety and efficiency. Our MC4 connector portfolio has the highest bankability rating available on the market.”

Stäubli products benefit from its innovative MULTILAM technology, which features specially formed and resilient contact elements. Constant spring pressure from MULTILAM louvers ensures continuous contact with the contact surface, resulting in a constantly low contact resistance that mitigates power loss and heat seepage. With more than 1 billion connectors in use across the planet, those incremental gains have made a huge impact on both cost and energy savings.

Stäubli, Power-Blox form partnership to work on energy storage solutions


Stäubli Electrical Connectors (formerly Multi-Contact), the pioneer and global market leader in electrical connectors for Photovoltaic solutions, and Power-Blox the award-winning Swiss start-up enter into a strategic partnership for innovative energy storage solutions.

With over 20 years of experience in the photovoltaic industry and more than 1 billion installed PV connector components, Stäubli Electrical Connectors provides more than 150 GW or 50% of the worldwide PV capacity. With the new technology called “Swarm Power”, developed by the Swiss start-up company Power-Blox and its intelligent energy cubes, an off-the-grid energy sup-ply can be produced without any technical know-how or configuration.

Power-Blox is the first modular solar energy system, which offers alternating current up to the megawatt range based on swarm technology. This revolutionary concept also allows for a completely mobile supply and functions as a portable outlet.

Power-Blox explains how it uses ‘swarm power’ to create intelligent autonomous energy grids

“The product and solution portfolio of Power-Blox fits very well into the strategic development of our ‘alternative energies’ business. Combined with our powerful and durable connector solutions for photovoltaic plants, these innovative systems and the swarm technology open up total-ly new fields of application in the growing market of energy storage systems”, says Franco Delvecchio, CEO of Stäubli Electrical Connectors and member of the Executive Committee of the Stäubli Group about the cooperation.

“Swarm Power” imitates complex systems by their nature to create fully autonomous and intelligent power grids all over the world. Anyone can create an independent, decentralized power supply grid without additional technical know-how. The “plug and play” solution consists of stand-alone energy cubes with an integrated battery, which can be expanded as desired, thus enabling a scalable power supply. Each cube can supply electricity which is independent of the grid and is supplied by external sources such as solar systems or wind energy. Typical applications include the supply of mobile or temporary installations for aid organizations, rural electrification in remote areas, military installations or as a reserve battery for bridging in power in the event of power outages in unstable public networks.
