For a long time, solar cells, energy storage, inverters and electric vehicle chargers have been installed as individual functional solutions without any thought of connecting them. This solves the need that the customer sees right now, but it doesn’t take into account future opportunities and challenges. Unfortunately, this also means an increased risk that they will cause problems with the grid connection and/or limit the possibility of effective control. So: think System right from the outset.
If you want to be able to control these individual function solutions from a common power and function perspective, such as a power tariff, this is a challenge with different commands and protocols. If we instead think about both function and system for our buildings, the flexibility needed will be built into the grid of the future. Furthermore, almost all modern appliances are powered by direct current behind a rectifier. These appliances are not always controllable from external control signals, but are based on a local function logic.
Specify the EnergyHub system for new construction
By specifying Ferroamp’s EnergyHub system for new construction, you make sure that solar electricity, energy storage and electric vehicle charging can take the grid connection into account. This is thanks to the fact that we can combine the control in all parts from one central converter. EnergyHub can also be integrated into local control systems via our API ports, so that other equipment can use streaming data from EnergyHub. It can involve, for example, starting the heat pump when there is overproduction of solar electricity and also storing energy in the accumulator tank. By thinking system, you increase flexibility and you also make sure that your skills as an installer or consultant are utilised in the best possible way.

System value and functional value
If you think about system value together with functional value, you meet both needs without compromising the customer’s initial and sometimes primary functional needs. One such example is the focus that is often placed on using batteries for solar electricity. You start with a function based on energy (kWh). The customer wants to be able to store the solar electricity to use the energy in the evening. The system perspective also takes into account the grid connection, and the battery can then be used in other ways. It can be used to protect main fuses during both production and consumption. The battery can then be charged with energy from solar electricity in the summer, but also from the grid when energy is cheap during the winter or on bad weather days. You get two benefits and new opportunities open up, for example to build a solar electricity installation that is bigger than the main fuse, which is ideal based on the consumption pattern.
Many solar electricity customers have had to upgrade their main fuse so that they could fit a bigger solar electricity installation in order to compensate for their annual consumption. The increased cost of the main fuse eats up a lot of solar electricity production. An EnergyHub system can address this in many ways, either with batteries or by enabling control of the heat pump or electric vehicle charging, depending on the conditions.
As a supplier of an EnergyHub system, you have a tool that enables you to help the customer for many years to come. If there is interest in more solar cells or batteries to handle more charging points, you can add new functions based on V2G (where the electric vehicle’s battery becomes part of the property’s electrical system) or backup solutions to handle critical loads, you then have a platform that gives you both physical control and flexibility.
