New developments in inverter architecture suggest that string inverters have charged forwards again to take on the challenge and kick central inverters off the throne in the utility-scale market. Hardware design innovations allowing to cut down BoS capex and improve efficiency of the plants might push string inverters further to take more space in the utility-scale market place. The battle between string and central inverters is heading into another round. Increasing price pressure and ever new possibilities of digitalization have evoked a wave of high-tech solutions to age-old PV issues. Now that most inverter suppliers are brushing up their portfolios with PID prevention and recovery systems, virtual power plant solutions, energy management systems, and tools that allow for remote or even predictive maintenance, it appears the hardware development of inverters has been relagated to the sidelines of the inverter game. Manufacturers, however, have not forgotten hardware and new developments should not be neglected as they retain great potential.
