Inverter – GOODWE – GW100K07-ETC
Product details
ETC
ETC by GoodWe is a series of three-phase high-voltage hybrid inverters with a rated output power of 50–100 kW, designed for energy storage systems in the commercial and industrial sectors. Compatibility with Lynx C storage systems helps increase self-consumption and reduce peak electricity demand. Backup power with UPS-standard switching in under 10 ms supports uninterrupted power supply for businesses.
Key benefits of ETC
- Power and operation of the PV system: rated output power of 50–100 kW, 1–2 MPPT systems and maximum PV input power of 65–130 kW, depending on the model.
- Compatibility with Lynx C: support for energy storage systems with capacities of 101–936 kWh and the ability to connect up to three Lynx C batteries to a single battery input.
- Peak demand reduction: the peak shaving function helps reduce electricity costs and avoid additional charges.
- Backup power: UPS-standard switching in under 10 ms and a rated apparent power of the backup circuit of 50–100 kVA, depending on the model.
- Efficiency: maximum efficiency 97.6%, European efficiency 97.3% and MPPT efficiency 99.9%.
- Integrated protection: protection against islanding, overcurrent and short circuits in the AC circuit, as well as type II surge arresters on the DC and AC sides.
Who is this a good choice for?
The ETC series is designed for commercial and industrial businesses looking to increase self-consumption and reduce costs associated with peak demand. It is also a solution for businesses whose operations depend on an uninterrupted power supply — a backup circuit and switching in under 10 ms address this need.
