IP66 rating
Light & compact
Maximised energy yield for high-power PV rooftops
A perfect fit for three-phase commercial and industrial (C&I) systems with high-power PV modules, the SDT G3 inverters allow for high current input. The inverters are designed for silent operation, while the optional Type II surge protection on both AC and DC sides enhances overall safety. With Arc Fault Circuit Interrupter 3.0 (AFCI 3.0), the safety of the system is assured as the inverter is able to detect arc fault failure, sending alarms through monitoring systems and shutting down the inverter operation simultaneously.
Increased yield (both on AC and DC)
Highest safety standards
Enhanced performance
Smart and silent operation
IP66 rating
Light & compact
Maximised energy output
The SDT G3 inverter can generate up to 10% additional power compared to the nominal output with higher efficiency, increasing the overall yield. Low start up voltage enables power generation from early morning to late evening. With up to 20A maximum current input per string, the inverter series is compatible with high-power modules. The SDT G3 comes with three to four MPPTs enabling improved system design flexibility and energy harvest levels.
Increased yield ( 110% AC power )
Up to 20 A max. DC input current per string
Low start-up voltage
Highest safety standards
With optional PID recovery and Arc Fault Circuit Interrupter (AFCI) functions, the inverter is able to detect arc fault failure, sending alarms through monitoring systems and shutting down the inverter operation simultaneously. Type II Surge Protection Device (SPD) on both AC and DC sides protects the system from lightning hazards, enhancing overall safety.
Optional AFCI 3.0 and PID functions
Optional surge protection SPD type II
IP66 rating
Smart and efficient operation
This SDT G3 three-phase commercial and industrial system benefits from valuable features like energy management as well as modern and compact design. Additional functionalities such as 24-hour load monitoring can be facilitated when paired with GoodWe's smart meter. Natural convection is the main cooling method, thereby facilitating silent operation.
