SDT G2 Series Design & Technical Strengths

GoodWe SDT G2 Series inverter is especially designed for three-phase residential and small commercial projects. One of the benefits of the SDT G2 Series is its user-friendly compact design. The SDT G2 inverter is 45% smaller than the first generation and much smarter than other competing products available on the market. Its light weight and reduced size make it easily transportable and extremely convenient to install and maintain. It also offers 50% DC oversizing capacity and 10% AC overloading, which makes it powerful and smart. The maximum efficiency of the inverter is as high as 98.4%. In addition, SDT G2 Series inverters can be customized with an integrated shiny LCD screen, which makes the user interface more practical and intuitive.

Advanced Safety, Protection and Fault Detection

Both the DC side and AC side are equipped with surge protection to protect the inverter from electricity surges, ensuring maximum safety of the whole PV system. SDT G2 is integrated with Arc-Fault Circuit Interrupter (AFCI), enabling the inverter to detect arc fault failure, making SDT G2 Series inverter an intelligent device from an O&M point of view. Since the inverter comes with life-long free SEMS monitoring solution, it can send alarms through the monitoring systems and break the circuit simultaneously, thus reducing the risk of fire hazards. SEMS is All-in-One monitoring solutions can help keep track of faults and enables fault analysis and suggestions to keep the PV plant and inverter safe and protected.

Advanced Ventilation System

SDT G2 inverters are designed to perform under extreme conditions. Excessive heat and component operation heat reduce the life and efficiency of the inverter. GoodWe’s SDT G2 Series inverters are integrated with the best solution to this issue. The inverters are made tough and ready for extreme environments; with an advanced ventilation system, SDT G2 Series inverter is able to dissipate heat efficiently and keep inverter operations efficient even in hot environments.

Data Security

The inverter has data breakpoint resuming function, which means it can re-upload data to the monitoring system when it reconnects to the server after going off-line. The data is encrypted during the transmission process and data on the server has backup. All these features ensure 100% data security.

Most Reliable Inverter Company

GoodWe inverters offer reliable operation and excellent performance and are well recognized by customers worldwide. GoodWe’s philosophy is to always create win-win partnerships with customers by identifying and integrating the most advanced components and techniques available while offering an unparalleled after-sales service.

DEHNcombo protects, no matter small rooftop PV systems or multi-megawatt systems!



The new DEHNcombo YPV combined arrester from the lightning and surge protection specialist DEHN safely protects PV systems from surges caused by lightning interference. The arrester offers a number of application advantages for PV systems in a single device. The varistor-based protective device combines a type 1 lightning current arrester and a type 2 surge arrester and incorporates a tried and tested Y circuit. DEHNcombo YPV efficiently protects the DC side of the inverter, the combiner box or the PV modules. This new arrester can be used for small rooftop systems, but also for systems of the multi-megawatt class.

Terminal Equipment Coordination

DEHNcombo YPV is a compact, lightning current carrying combined arrester for the DC side of photovoltaic systems which can be used without additional backup fuse up to a short-circuit current of 10 kA. It has a total discharge current of 12.5 kA (10/350 μs) and a low voltage protection level, thus ensuring coordination with terminal equipment. DEHNcombo YPV is ideally suited for earthed (earthing of DC+ or DC-) and floating systems. Because its rated voltage is the same for all protection paths, Arresters for system voltages UCPV ≤ 1200 V and UCPV ≤ 1500 V are available for effective protection of terminal equipment. The tried and tested fault-resistant Y circuit prevents damage to the surge protective device in case of insulation faults in the generator circuit.

The arresters are already safe to touch (IP20) and do not require an additional cover. They feature an operating state/fault indication which is easily visible – even from the outside – thanks to indictor flags in the inspection window. Optionally, the arresters are also available with floating remote signalling contact (FM) for remote monitoring.

Of course, the DEHNcombo YPV protective devices meet the test requirements of the EN 50539-11 product standard and can be used in PV systems according to IEC 60364-7-712. DEHNcombo YPV will be available as of September.
