PV storage: inverter control system requirements. Multi Flow technology

The rising cost of electricity and the drop in prices of PV systems experienced in recent years show that today the costs of PV generation are considerably lower than the purchase price of electricity. Moreover, the constant fall of feed-in tariffs has resulted in an increasing number of installation owners using the energy they produce before injecting it into the grid. To maximise self-consumption, storage systems are often used alongside energy management systems.

PV storage systems require inverters with more complex control systems and energy flows than those that have been available to date, given that they offer additional functions:

• Optimised inverter programming to make the most of valley tariffs.
• Improved grid quality.
• Emergency function in the event of a power outage.

The Fronius Energy Package and Multi Flow technology meet the strict requirements of a control system for a modern storage system. Read more…
