Inverter – GOODWE – GW8000-SDT-30
Product details
SDT G3
SDT G3 by GoodWe is a series of three-phase string inverters designed for residential systems and small commercial installations with high-power photovoltaic modules. It offers a rated output power of 8–20 kW, two MPPT trackers and a maximum efficiency of 98.5%. The inverters are designed for quiet operation and, with the addition of GoodWe accessories, enable load control and round-the-clock energy consumption monitoring.
Key benefits of SDT G3
- Rated power 8–20 kW depending on the model and a maximum efficiency of 98.5% across the entire series.
- Two MPPT systems with an operating voltage range of 140–1000 V and a maximum input voltage of 1100 V.
- Intelligent energy management including load control and round-the-clock consumption monitoring with the addition of GoodWe accessories.
- Type III surge arresters on the AC and DC sides as standard; type II surge arresters and AFCI 3.0 arc fault protection are available as options.
- Protection rating IP66 and an operating temperature range from -30 to +60°C.
- Nighttime power consumption below 1 W and natural convection cooling or intelligent active cooling, depending on the model.
Who is this a good choice for?
The series is designed for households with three-phase photovoltaic systems and businesses using small commercial systems with high-power modules. The 8–20 kW power range allows a suitable model to be selected for the system, while users interested in load control and round-the-clock energy consumption monitoring can access these functions by adding GoodWe accessories.
