Product Portfolio
  • PV Grid-Connected Inverters

  • SunAccessTM Grid-tConnected inverter is core device in the photovoltaic power plant. Sungrow has several years experiences in R&D and production & application of energy conversion system in railway and industry field. These elements ensure high effective performance of our inverter product.

    There are two technologies with transformer type and no transformer type in Grid-connected inverter product series, which can meet different application requirements.
    Because solar energy power generation system is applied in many under-developed and remote areas, maintenance is difficult, so high reliability of our product is required to ensure stable operation of power station in long term. At present, great amount of inverter of our company is successfully applied in photovoltaic power generation system in domestic and foreign market. Aiming at current power electronic system application, Sungrow also develops a monitor software with multi-function off-grid and Grid-Connected inverter, which can monitor the operation condition of solar energy power generation system. The software also has accumulation function of electrical capacity, system analysis function and rich parameter setting function, etc. Sungrow Grid-Connected inverter feeds power generated by solar energy battery to grid through inner power regulator at maximum degree.
    Grid can absorb enormous energy by itself, so no storage battery is required by grid-Connected power grid, so system investment is saved and maintenance is reduced, which has wide application prospect.
