Sungrow SG350HX-20_V+ – Three-phase industrial PV inverter 350kW (Grid-connected)

High efficiency, multi-MPPT inverter for commercial and industrial systems - up to 12 MPPT, 1500V DC, IP66, intelligent communication and monitoring

Sungrow SG350HX-20_V+is a new generationthree-phase string inverter, designed for large-scale photovoltaic systems withhigh voltage 1500V DC. Offers up to12 MPPT inputs, each with 2 strings, making it extremely suitable for high power installations, asymmetrical configurations and complex topologies.

The inverter is distinguished bymaximum efficiency up to 99.02%, reactive power response <30 ms, active IV Curve diagnosticsandPower Line Communication (PLC). He providesstable operation in weak networks (SCR ≥1.15)and guaranteesfull compliance with global network codes.

Applications:
✔️ Industrial and commercial photovoltaic parks
✔️ Systems with high energy density and 1500V DC architecture
✔️ Projects with a requirement for high efficiency and level of protection
✔️ Installations with precise reactive compensation and monitoring

The Sungrow SG350HX-20_V+ is an engineering solution for the future – combining scale, intelligence and reliability for megawatt class projects.
