Key features of the GoodWe MS G3 Series

  • Triple Maximum Power Point Trackers (MPPTs):  The MS G3 shines with its three independent Maximum Power Point Tracking (MPPT). This allows you to optimise power generation even on complex rooftops with panels facing different directions or experiencing varying degrees of sunlight exposure. Each MPPT tracks the maximum power point of its connected solar panel string, ensuring you get the most out of your entire system.
  • Ultra-low startup voltage (50V):  Australian mornings can start with relatively low light levels. The MS G3’s impressive 50V startup voltage means your inverter converts solar energy into usable electricity earlier in the day, maximising your overall power generation.
  • High input current capability:  The MS G3 series supports a maximum DC input current of 20A per MPPT. This makes it ideal for handling high-power solar panels, a trend gaining traction in the Australian market. By efficiently utilising these advanced panels, you get the most out of your solar investment and potentially lower your Levelized Cost of Energy (LCOE).
  • Potential Induced Degradation (PID) Recovery:  PID is a phenomenon that can affect solar panel performance over time. The MS G3 boasts a built-in PID recovery function that helps mitigate this degradation, ensuring your solar panels maintain optimal output for longer.
  • Fanless natural convection cooling:  The MS G3 series utilises a fanless cooling system. This translates to quiet operation, a welcome feature for residential installations where noise can be a concern.
  • Easy software updates:  Keeping your inverter software up-to-date ensures optimal performance and access to the latest features. The MS G3 allows for quick and convenient software updates via a USB connection.
  • Compact and stylish design:  The MS G3 is designed for easy integration into your home. Its compact size makes it suitable for indoor installation, and its sleek design complements modern aesthetics.
