GoodWe is rolling out its new compact 20 kW SDT series inverter for three-phase households with high capacity density, which includes two MPP trackers and a wide input voltage range to ensure design flexibility and compatibility with high-output PV panels.

Problem

As residential rooftop PV projects continue to expand toward larger systems up to 20 kW, while the use of single-phase inverters in a three-phase environment might cause faults due to unsymmetrical grid issues, while many network operators will not allow an imbalance across the phases. Therefore, the only solution is either to install three single phase inverters for each phase or one three phase inverter that will work across three phases. 

Solution

Three-phase feed-in is thought to be the best solution for grid symmetry leading to the highest yields and contributing to a stable grid. Compared with equivalent competitor products, the 20 kW SDT series inverter is said to be the most compact and lightweight inverter on the market with the highest capacity density and maximum efficiency of 98.6%. With a weight of just 26kg, the new SDT series is easier to handle and install than other three-phase inverters. Specially designed for three-phase home solar systems, it allows 130% DC oversizing to fully maximize capacity. In addition, with 110% AC overload and a start-up voltage of 180 V, guarantees an earlier generation of power and a longer working time for maximum energy harvest.

Applications

Three-phase residential and small commercial PV systems.

Platform

The SDT series is designed for today's high-output PV panels, enhanced to meet the latest grid compliance standards while providing unprecedented power and dual, independent MPPT.
