High-power string inverters, rather than simply making centralized inverters smaller or string inverters larger, take into account the low cost of centralized inverters and the flexibility of small-power string inverters. It is a market-oriented product that has evolved in response to industry changes.
String inverters consist of power switches such as insulated gate bipolar transistors (IGBTs). This kind of power device has issues such as tail current and diode reverse recovery, which lead to high switching losses. Furthermore, these phenomena are affected by temperature, leading to higher power losses, especially for static-cooled solutions.
With an overall system efficiency close to 98% and a power density of 2.3kW/L, the string inverter reference design demonstrates great performance. In addition, the implementation of an integrated gate-driver solution could lead to cost reductions when considering the total system cost.
Before 2013, 20kW string inverters were considered high-power. In 2014, 28kW appeared, and the 40kW ones followed by in 2015, and the power increased at a rate of 10kW per year thereafter. Until 2017, the 1500V PV system promoted the breakthrough of 100kW inverters, later reaching 200kW and then 300kW.
