Directing Solar Power

Manufacturers will present their new inverters at Intersolar Europe

  • Battery inverters manage more than just solar power.
  • The range of solar inverters available is growing.
  • Find out about the latest innovations in the inverter industry.

In the past, solar inverters performed one single task: converting direct current generated by photovoltaics into alternating current which can be fed into the grid. With the rise of storage solutions, manufacturers are developing inverters which are able to perform other tasks, such as directing electricity flows between solar modules, batteries and the power grid. Come to halls B2 and B3 at the Intersolar Europe to find out how this works and which new solutions the industry has to offer.

Preparing solar power for batteries

Solar storage devices can be connected to a photovoltaic installation in two different ways: They are either connected after the inverter to the house’s alternating current circuit (AC-coupled) or inserted in a direct current circuit between the PV installation and the inverter (DC-coupled).

In AC-coupled systems, the photovoltaic installation and battery are connected to the power grid via separate grid inverters, making it easy to retrofit existing solar power systems. In DC-coupled systems, the storage devices are connected to the solar module in a direct current circuit. In this case, only a single inverter is needed to connect to the grid.

The range of solar inverters available is growing

For a long time, manufacturers have been developing innovative inverters which are able to manage the most diverse energy flows in all directions – regardless of whether in direct or alternating current. They can supply a household with solar energy from the roof or from a storage device, and store the solar power directly in the battery or in the household network. Other products combine the advantages of a solar inverter with those of a battery inverter. Such devices require one less component, and therefore save costs.

The range of inverters available has grown in recent years, and now extends beyond simple solar inverters with one MPP tracker and devices with several MPP trackers for photovoltaic installations with east- and west-oriented solar modules. In addition to innovative battery inverters which integrate storage and solar power generation, and thus perform the role of an energy management system, the industry is also working on new prototypes for micro-inverters and on modern device concepts for photovoltaic power plants.
