The energy transition will succeed only if the majority of our electricity is generated from renewable energy sources. But these are subject to weather-dependent fluctuations. The SMA Energy System for battery-storage power plants provides grid-forming capability, which is currently provided by decentralized power plants, and feeds green electricity with a stable frequency into the utility grid. This turns power plant owners and operators into key players on the electricity market.

As a product manager at SMA, Isabella Caschetto and her team develop digital services for new business models of large-scale PV and battery storage systems – essential energy sources for the future renewable energy supply. Customers include PV and battery power plant operators as well as grid operators from all over the world. For them, grid stability and the supply reliability of renewable energies are key issues.

The PV industry is using high-current modules to combat rising system costs. This type of module consists of M10 or larger PV cells, which can accommodate correspondingly high MPP currents (>12 A). Read on to find out what needs to be taken into account in the choice of inverter and what kind of misconceptions can commonly be encountered, as well as the difference between short-circuit current and maximum input current.
