DC provides controllability

The argument for using DC for PowerShare technology is that it provides controllability in the endpoints, and thereby full control over where the energy goes.

Local resource allocation

With PowerShare, solar energy and batteries can be used collectively in multiple buildings. This creates major financial opportunities and provides more people with the opportunity to invest in solar cells.

Award-winning technology

The innovative feature of this technology is the ability to control energy and power between solar cells, batteries and electric vehicles via a local DC grid, even between different buildings.

Stronger together

By linking several EnergyHub systems, multiple buildings can cost-efficiently share energy and power resources in a local DC grid.

By taking full advantage of the roofs that receive most sunlight, solar energy can be shared with other buildings with less favourable conditions. Solar energy can be used collectively by everyone in a tenant-owner association.

You retain complete control over power consumption in the connected buildings, paving the way for new business models with energy-efficiency services and energy trading. Quite simply, more tenant-owner associations will have the opportunity to invest in solar cells.

PowerShare increases your own use of the energy you produce, while at the same time the benefits of energy storage are shared among more buildings.

Recognition for Ferroamp’s PowerShare includes the E-Prize 2018 and the Smarter E Award 2018 for its innovation.

New energy technology saves millions for properties and solves Sweden’s grid problems

According to Svenska Kraftnät, the authority responsible for Sweden’s national grid, the lack of electricity capacity presents an increasing risk. Faced with expanding its electric vehicle charging network and the threat of increasing electricity prices, municipal housing company ÖrebroBostäder (ÖBO) has created its own electricity system using the latest technology from Ferroamp, including solar panels and battery storage. This has reduced consumption from the national grid by half and saved millions of SEK on electricity for the whole property portfolio.

Six years ago, they had reached the limit of their energy-saving measures; they could do no more. Using the new EnergyHub technology from Ferroamp, that limit has been moved far into the future. ÖBO has created its own grid that transfers current between the phases; producing, storing and selling electricity. It was a strategic choice of direction that became a dream solution.

At the time of its last tertiary report, ÖBO had more than halved electricity consumption compared to 2005, from 59.7 to 29.4 GWh/year. This represents many millions of Swedish kronor, both in lower operating costs and higher property values.

ÖrebroBostäder’s strategy for the future is now clearly staked out. Building by building, district by district, the municipality will convert to the new electricity system. Self-generated electricity from solar panels is stored in large batteries, and distributed and balanced between low and high energy consumption in buildings using EnergyHub. They have thereby created their own grid to transfer current between their properties as required. At the same time, they contribute to solving Svenska Kraftnät’s problems with frequency regulation due to high and uneven consumption.

By producing electricity ourselves, we can store and share energy to make our energy consumption more efficient. ÖBO is moving from building level to system level and can at the same time offer energy services to the national grid.
