Almost all electronics in our homes are powered by direct current. LED lighting, fans, refrigerators, TVs, computers, etc. In the devices, there are small rectifiers that convert the alternating current in our wall outlets to the direct current needed to power the devices. Solar panels produce direct current, and batteries in both our homes and cars are powered by direct current. By building a direct current infrastructure, we reduce energy losses between solar cells and batteries and enable the future connection of more direct current components directly to the direct current network. This will enable significantly reduced energy losses and more efficient and intelligent energy use. Direct current technology also offers greater controllability than alternating current, resulting in a more flexible system.

PowerShare is Ferroamp’s patented technology for sharing electricity between buildings. A PowerShare connects the EnergyHub units in several different Ferroamp systems with their own grid connections in a network.  This gives you the opportunity to share electricity from the solar panels and the storage capacity of the batteries between several buildings. We can then control the distribution of electricity smartly in the DC grid based on the measurement values we collect from each grid connection. 

You do not need to replace your photovoltaic system to install the Ferroamp system. You can supplement your facility with an EnergyHub to get access to dynamic phase balancing, smart metering of imports, exports, energy use, etc. and to control and act as a load guard / power monitor for charging boxes for electric cars. You can also connect one or more batteries to control consumption and storage. If you also want to connect the solar cells to the Ferroamp system, you can supplement with solar string optimizers, connect the solar electricity production to the system.

 battery gives you as a user a number of possibilities and freedoms. You can increase the self-consumption of solar power by charging the battery during the day and discharging it when the solar panels stop producing. The battery can also be charged from the grid at night when electricity prices are generally lower to be discharged during the morning when prices are higher. You can also keep the power output from the grid down by cutting the power peaks and discharging when consumption in the property is at its highest.  With a battery, it is also possible to participate in the frequency regulation market through aggregators. This means that some of the battery’s capacity is made available to help keep the frequency on the grid, which can be lucrative.

Ferroamp EnergyHub should be installed in a weather-protected space free from condensation. Since it is powered by a fan with approximately the same noise level as a stationary computer and generates some heat load, it can be advantageously installed in a garage, basement, attic, or storage room to avoid disturbing noise.

The house will not lose power if the EnergyHub breaks down. This will only mean that: 

• No solar power is produced 
• The battery does not run 
• Measurement and phase balancing are not active. 

The house still receives electricity via its grid connection to the general electricity grid.
