THE ENERGY FLOWS IN AN ENERGY STORAGE SYSTEM

The PV generator can supply loads in the household and charge the battery at the same time. If there is a surplus, it can be fed into the grid.

Loads in the household can be supplied by the PV generator and the battery at the same time.

If there is a surplus, loads are supplied and the battery is charged in parallel. When there is a consumption situation, power is supplied by the PV generator and the battery.

An additional AC source such as a wind turbine or existing PV system can be connected to the inverter.

The inverter controls the energy flows in the storage system.

HIGH SELF-CONSUMPTION RATE THROUGH SIMULTANEOUS ENERGY FLOWS

Multi Flow Technology allows simultaneous energy flows in all directions, which means less grid usage and less feed-in – i.e. lower costs and a higher yield.

In this application, for example, a Fronius Symo GEN24 6.0 Plus with PV production of 6 kW can supply the household with 3 kW and at the same time use the other 3 kW to charge the battery*.

RELIABLE POWER SUPPLY EVEN DURING A POWER FAILURE

In backup power mode, for instance during a power failure, Multi Flow Technology provides a backup power supply from the PV system and the battery. The PV system can supply the household with solar energy even if the battery is already discharged.

In this application example, in the event of a power failure, the loads in the household are supplied with power and the battery is charged at the same time*.

EXPANDING THE PV SYSTEM TO INCLUDE A STORAGE UNIT AND A HYBRID INVERTER

Owners of a PV system without a storage unit can retrofit their PV system with one and use the advantages of the Multi Flow Technology for their own benefit.

In this application example, when there is a surplus (green line), the loads in the household are supplied with power and the battery is charged at the same time. When there is a consumption situation (blue line), power is supplied by the PV generator and the battery. 

ENLARGEMENT OF THE PV SYSTEM WITH AC COUPLING

Multi Flow Technology allows both DC and AC coupling of the storage system. It is therefore possible not only to integrate the storage solution into existing PV systems, but also to incorporate small wind generators or mini-cogeneration units into the storage system.

In this application example, when there is a surplus (green line), the loads in the household are supplied with power and the battery is charged from the DC and the AC side. When there is a consumption situation (blue line), power is supplied by the DC and AC-side PV generator and the battery
