Product Overview
The GoodWe ET Series 100kW hybrid inverter is a three-phase, high-voltage inverter designed for commercial and industrial solar-plus-storage systems. It combines PV generation, battery integration and back-up capability in a DC-coupled architecture that is suitable for sites looking to improve self-consumption, peak shaving, time-of-use control and broader energy management.
For the 100kW model referenced on the source page, the GW100K-ET-G10 offers 8 MPPTs, dual independent battery inputs, up to 200kW PV input power, and up to 110kW charging and discharging power. Its wall-mounted design, IP66 protection rating and smart monitoring features make it a practical option for demanding C&I installations where performance, flexibility and system resilience matter.
Key Features
- Three-phase 100kW hybrid inverter designed for commercial and industrial solar-plus-storage applications.
- DC-coupled architecture helps simplify system design while supporting smarter energy management.
- 8 MPPTs with 2 strings per MPPT support flexible PV array design across more roof sections or orientations.
- Up to 200% PV oversizing support and up to 21A per string help accommodate higher-current module configurations.
- Dual independent battery inputs provide greater flexibility for battery configuration.
- Supports lithium-ion battery systems with CAN communication to the BMS.
- Generator start-stop control via DI/DO interfaces adds flexibility for hybrid and backup-focused installations.
- UPS-level switching of less than 4ms supports critical-load continuity during grid outages when used with the required STS equipment.
- IP66 ingress protection and anti-corrosion class C4 support use in demanding installation environments.
Applications
- Commercial and industrial solar-plus-storage systems.
- Sites aiming to improve solar self-consumption and reduce grid reliance.
- Installations using peak shaving and time-of-use energy strategies.
- Facilities requiring backup support for selected critical loads.
- Projects needing flexible PV design with multiple MPPTs and dual battery inputs.
