By now, you already know that there are plenty of benefits from Sungrow inverter products. Some of these benefits are high efficiency, transformerless design, and low noise operation. This is why many consumers widely appreciate SG2K-S/SG2K5-S/SG3K-S.
However, did you know that it now has a newer version? Its newer version is the SG3K-D / SG5K-D – Sungrow premium inverter, and if you are interested in knowing the differences between both versions, then you are on the right page. In this article, we are going to discuss the difference between the older and newer version. We also include some important facts that you should know about when you buy any of these models.
So, are you ready? Let’s get started!
The Difference Between SG3K-D / SG5K-D and SG2K-S/SG2K5-S/SG3K-S
Here are the significant difference between the two models:
Both the older and newer models have high-yield. In fact, the SG3K-D / SG5K-D premium residential model is only better by .2 max efficiency compared to the older one. Both model’s MPPT current and compatibility with bifacial modules are also very similar.
If you are wondering what MPPT means, it stands for Maximum Power Point Tracking. It is only sometimes only referred to as PPT. It is a commonly used technique in photovoltaic solar and wind turbine systems to help maximize the extraction of power to get the best out of the dollar panels and the battery banks.
The term Bifacial modules may not also be familiar to you, but it is a type of solar panel technology. It is one of the older types, so if you already have this existing in your house, you will not need any type of retrofitting to make it compatible with SG3K-D / SG5K-D or its older model.
In terms of management, both models are compatible with smart management. They both have 24 hours of real-time load monitoring that you can access using the Sungrow power app or website.
This real-time monitoring is extremely convenient. Connecting your device is super easy, and the interface is user-friendly as well.
When it comes to inverters’ safety and durability, Brisbane North Solar assures that both models have excellent safety and durability features.
Both are equipped with a fault circuit interrupter. This can significantly prevent fire because of my electrical problems. It works by breaking the circuit when it discovers an electric arc.
Both models are also equipped with a built-in type 2 DC&AC surge protection device and certified PV Isolator. The type 2 DC&AC surge protection device is the primary protection system for electrical installation with low voltage. It works by preventing the spread of overvoltages and protecting the loads.
On the other hand, the certified PV Isolator is another type of electrical safety device that disconnects itself from the modules within a PV system. These are typically used as manual switches for disconnection for repair, installation, and maintenance purposes.
Just like the other factors, there is no major difference between the older and newer models. Both have a plug and play installation, which means that it is no hassle.
You can also check the accuracy of your commissioning using the brand’s app. The app is easy to use and easy to understand, so you are sure to get things right as long as you follow the installation manual thoroughly.
However, where the two models differ is in weight. The SG3K-D / SG5K-D is a little heavier at 11.5 kg, while the SG2K-S/SG2K5-S/SG3K-S is lighter with it only being 8.5kg. But, their designs are still compact, so it does not consume a lot of space.
Which One Should You Choose?
Now that you know about the difference between SG3K-D / SG5K-D and SG2K-S/SG2K5-S/SG3K-S, the question is now; which one should you opt for? The obvious answer to this question is the newer SG3K-D / SG5K-D model since it has more features and is easier to use and install.
However, do not discount the SG2K-S/SG2K5-S/SG3K-S as your solar installation Brisbane just yet. It is more affordable than the newer version, and it is still an excellent inverter. So, suppose you don’t mind sacrificing a little efficiency for a lower cost and some management features. In that case, the SG2K-S/SG2K5-S/SG3K-S is definitely a good choice for you.
By the end of the day, it all boils down to your preference and budget. Regardless, you will be getting a good deal with any of these two inverters for Brisbane solar installation.
Sungrow is indeed an excellent brand, and they have hassle-free inverters worth considering. However, suppose you are picking between the SG3K-D / SG5K-D and SG2K-S/SG2K5-S/SG3K-S. In that case, there is really no major difference between the two models except on the weight and efficiency. So, which one do you prefer; the older version or, the newer one?
What our customer have to says
Alex’s team were prompt, very friendly and finished four air con installations ahead of schedule. The guys cleaned up after their work and were very patient with our over affectionate dog! Thanks Alex.
Can I just say, your guys were all great. So friendly, clean, and well organised. Except for when they lost their ute keys. That was hilarious. Thanks for a great job
Highly professional and work done to exceptional quality. Had 3 separate split units installed and more than happy with the outcome of each, both inside and outside the house.
MacDonald Air and Electrical have recently installed a split system air conditioning unit at my property. They were very helpful explaining what was needed and provided a very competitive quote. They arrived at the agreed time and cleaned up any mess from their work before they left. I was very happy with their service.
