The brand new XS model from GoodWe is an ultra-small residential solar inverter specifically designed to bring comfort and quiet operation as well as high efficiency to households. Its capacity ranges from 0.7kW to 3.0kW and its most outstanding characteristics are its light weight, which is 5.8kg, and its extremely small size, equivalent to an A4-sized piece of paper, which makes it particularly easy to carry & install. Remarkably, it offers a 30% of DC input oversizing and it’s able to achieve a maximum European efficiency of 97.2%. Conveniently, the communications options available on this inverter are both LAN & Wi-Fi.

A4 Size, Super Light

 Compressing 3KW DC/AC transforming technology into an A4 size inverter is unbelievable. However, GoodWe did it! Weighing less than 6 kg, inverters can be easily installed! Additionally, it also significantly reduces shipment and stock cost.

33% DC INPUT OVERSIZING        AND            97.2%     EUROPEAN EFFICIENCY

 Even though the XS Series is extremely compact and tiny, it doesn’t mean standard features are sacrificed. The XS is still equipped with 30% DC oversizing                     capability which allows full load output during extreme weather conditions and what’s more, its European Efficiency can reach 97%, which is even more compared to its predecessors. NS Series. Small, light, compact, and capable.

LAN/WIFICommunication

An optional LAN/WIFI communication offers customers different monitoring methods to cater for different needs. Customers are able to choose the most convenient way to monitor their solar systems. It also allows the customer to switch into another monitoring method after installation. GoodWe cares about your feelings and experiences.

SDT G2 Series
(4-15KW | Three Phase | 2 MPPT)

 

 

 

 

 

 

The SDT G2 series of inverter from GoodWe is one of the best options available in the residential & commercial sectors owing to its technical strengths, which make it one of the most productive inverters in the market. Because of its high efficiency of (98.3%), the enhanced oversizing & overloading capabilities and the fact that it does not require a null line for installation, SDT G2 represents an outstanding improvement in the industry.

2nd generation of GoodWe SDT series is downsized by more than 50%. However, being compatible with bifacial modules, the competency of this half size successor is considerably improved. With 50% DC input oversizing, 10% AC output overloading capability, it drives your inverter to its full capacity by adding extra reflections from the backside of bifacial panels, to increase your power output under low solar radiation conditions.

BUILT-IN ANTI-REVERSE CURRENT

In regions where solar power is not allowed to be reverberated to the grid, installers can easily set an export limit through the GoodWe app with one simple-click, as SDT G2 has integrated a built-in anti-reverse current function into the inverter.

ARC-FAULT  CIRCUIT INTERRUPTER

Safety First! With AFCI, the inverter is able to detect arc fault failure, sending alarms through monitoring systems and breaking the circuit simultaneously. GoodWe does not only deliver efficiency, reliability, but security as well.
