New Technology of E3 / DC powered multi-family houses for about 90 percent … – SolarServer

The E3 / DC GmbH (Osnabrück) has developed a concept that could the housing industry could electrify properly, the company reported in a press release. The wholly-owned subsidiary of the energy company EWE has now implemented in Oldenburg for the first time their concept of “Energiefarmings” in an apartment house.

The result: The power will come to around 90 percent from its own production (photovoltaic and cogeneration) – and heating costs (gas) would be reduced to about half ,

The Energiefarming concept to come to fruition in other, already planned projects.

Two power storage systems with a capacity of 13.8 kWh in use

In the Oldenburg apartment building, there are two three-phase power storage systems “S10 E12″ of E3 / DC with lithium-ion batteries from Panasonic with a capacity of 13.8 kWh in use. You are at the heart of the concept, which have been implemented within the framework of a technical restoration with an excellent price-performance ratio and its scaling in the housing sector is possible for a variety of applications.

When Energiefarming is one of the home power plants, the farm manager, connected to the house connection. The farm manager controls the second device, the farm slave at any time and also monitors all energy flows in the respective mains.

The house power plants can link both DC alternator and caching their energy flows with maximum efficiencies thanks to the “TRILINK” technology emphasizes E3 / DC.

The output will double by the connection of two devices to 6,000 watts. Only in this way succeed year-round self-sufficiency levels in the highest power of more than 90 percent, the company said.

For E3 / DC Pilot project in Oldenburg adjacent to the roof-mounted photovoltaic plant also a cascade of micro-CHP appliances include (current producing heating) and a hot-water heat pump (for hot water preparation in summer).

current price of the landlord favorable than that of the local utility

Finally lead the concept of E3 / DC, recently as an innovator in 2015 with the German SME Award “Top 100″ Award, to a win-win situation for property owners / housing sector and tenants. For tenants falling in said pilot even the “second rent” because the electricity price the landlord is more favorable than that of the local energy supplier.

From the perspective of the housing industry, finally, it offers a lucrative business opportunity: In addition to the income from renting the apartments, revenues come from the sale of electricity and heat to tenants added. The time investment costs pay off through depreciation and tax benefits within a few years, so E3 / DC.
