GoodWe ET Series Hybrid Inverter 100kW (8 MPPT - IP66)

The GoodWe GW100K-ET-G10 is built for large commercial and industrial sites that want to combine a big solar array with high voltage battery storage. It delivers 100kW of rated power and accepts up to 200kW of PV input through eight MPPTs and sixteen strings, with up to 21A per string and 42A per MPPT, so modern high power modules are well supported. Its DC-coupled architecture sends solar power directly to the battery without an extra conversion step, which improves efficiency for solar plus storage. The battery side has a nominal voltage of 600V, and each inverter can connect up to four GoodWe BAT 112kWh units, for 448kWh of storage in total. It offers smart modes for self consumption, peak shaving, time of use and grid support, and UPS level switching in under 10 ms, with the STS box fitted. For larger projects up to 15 units can run in parallel under the SEC3000C controller.

• Installers handling large rooftop solar-plus-storage projects

Why DC-Coupled Storage?

In an AC-coupled system, solar power is converted to AC, then converted again to DC to charge the battery, and back to AC when used. Each conversion loses a little energy. In a DC-coupled system like this one, solar goes straight into the battery on the DC side, so fewer conversions happen. The difference is not huge on any single day, but across thousands of cycles it adds up to more usable energy from the same solar array. It also means the PV and battery sit behind one inverter, which simplifies the layout.

GoodWe ET Series Hybrid Inverter - Compatibility and Installation Guide

• Use GoodWe’s high voltage BAT series, or another battery on the Good
• We compatibility list Add the STS box or cabinet for UPS-level backup switching
• Confirm that your site has a three phase supply and plan for a 97kg unit
• Use the SEC3000C controller if you plan to run several units in parallel
• Follow the manual for AC, DC and communication wiring
• Installation should be done by a qualified commercial solar installer
