The GoodWe ET50 hybrid inverter is a powerful and compact solution, specially developed for commercial and industrial energy storage applications. Thanks to its versatility and ability to be connected in parallel, it is ideal for both grid-connected and off-grid installations. The Inverter offers a high degree of flexibility to optimise system performance and maximise energy efficiency across various scenarios.

With intelligent operating modes such as Self-consumption, peak shaving, time-of-use (ToU) and grid support, the ET50 ensures optimal energy utilisation whilst reducing energy costs. In combination with the Static Transfer Switch (STS) box, the system enables reliable switching to backup mode to ensure an uninterrupted power supply during outages. Together with the GoodWe Lynx C battery system, the ET50 offers a complete and powerful energy storage solution.

GoodWe is currently offering Memodo customers free on-site commissioning support, provided the following conditions are met:

   - Use of the ET40/50-WR in conjunction with Lynx C storage (101–156 kWh) or BAT112.
