It is a debate which will always divide opinion on whether central or string inverters are best for utility-scale PV plants. Perhaps Sungrow have the definitive answer here with their virtual central inverter concept. They have managed to considerably increase the capacity of their string inverters to 125kW and their new virtual central inverter platform allows for centralised command and control of these string inverters. It seems like they have managed to mix the best parts of each option to produce a really neat solution. These new inverters start shipping this month so it will be interesting to see how they are received in the market, particularly in the US where central inverters dominate utility PV projects. It's great to see our client Sungrow maintaining their lead in PV inverter innovations.
