How the partnership with GE has made GoodWe a solid performer?

GOODWE-PARTNERSHIP-WITH-GE

The collaboration between Global Electronic Giant (GE) and GoodWe is a significant milestone for this growing inverter provider to get the satiety. It further encourages this brand to compete with the leading European inverter brands in terms of their intricate features, technological development, and improved reliability. Thus, it is easier for GE to replicate the qualities, as well as modern advancement of the European inverters, to get the worldwide acclaims from the European-obsessed customers.

Before GoodWe entered into the partnership with the GE, 32 other solar inverter manufacturers shortlisted for their thorough and detailed assessment to fulfill the selection process’s criteria. Those criteria comprise matters like technical issues to the company’s financial stability, the limit of the global outreach, brand’s reputation, appealing architecture, and brand awareness.
 

Is GoodWe inverter any good?

Usually, the price of the inverter commensurate with the abundance of the latest features. But in the case of GoodWe inverter, the matter is completely different. In conformity with the set of unique features as GoodWe possesses, the price turns out a lot cheaper. It is somewhat elusive to find an inverter these days, balanced perfectly with its tad price, against its attractive features. You won’t find any lacking in this GoodWe’s inverter, whether it’s a performance, value, battery, or any additional features like Wi-Fi and monitoring systems.

Mostly they are involved with string inverters, and hybrid inverter with the hybrid gives you the option of adding a battery any time in case you need it to store excess energy in winter or any particular day. Their R & D section in China is vast, and it enables the tech-freak to invent many more new inverters every year while keeping in mind the demand of the customers and the intensity of the competition of the inverter market.

customers and the intensity
 

How ideal GoodWe is in Australia’s harsh climate?

They are very reliable and seem to do any task without undergoing any gruesome damage. All of their inverters comply with the requirement set by the CEC (Clean Energy Council), and their GW5000D-NS and GW6000D-NS are affordable and compared against its price, which shows that their adaptability is widely praised for their durability and outstanding performance.
 

Is the efficiency of the GoodWe inverter up to the mark?

In this GoodWe inverter review, we won’t discuss the importance of the efficiency of the panels and inverter’s size, but you probably have known by now that efficiency is the vital part of the whole solar system based on which the amount of electricity will be produced and fed on by the users. If the panel size is too much, and the inverter size is not adequate to put up with the backup, then the entire system will go in vain.

Most of the residential solar inverters vary between 95 to 99%, whereas the GoodWe can generate the maximum efficiency of up to 97%. One of the latest editions added to the GoodWe’s cart is the NS series 1kW, which can produce up to 96.5% max efficiency. Also, the SDT series, equipped with the three-phase Dual-MPPT, a string inverter, which has a maximum efficiency of 98.3%, surpassing some of its competitors. Apart from this GoodWe inverter review, you can also check out some of the Cyanergy’s other inverter review content here to visualise the scenario.
 

Is GoodWe Inverters Battery ready?

GoodWe inverter is an excellent option if you contemplate installing the battery system either at the time of the installation or soon. From Feed-in-tariff to control the overuse of your grid-connection, this hybrid system, the combination of battery and solar inverter, can help you save the cost, hence increasing your ROI.

This is a multi-mode inverter, which involves a battery installation along with the set-up of the inverters. Not only does the inverter supply the DC power to the battery, but also it provides power to the grid and your home’s appliances in the form AC current. Having equipped with MPPT, it can track the amount of charge your battery requires, and when it’s the right time to draw the charge from the grid for a low price. You can consider adding a GoodWe GW5048D-ES Hybrid Inverter.
 

How much can GoodWe inverter cost?

Generally, an inverter plays a pivotal part in running your solar system effectively. As a result, inverter hereafter tends to account for 15-20% cost or even more of the system’s entire value. Any problem occurring in the inverter will directly impact the daily consumption of your electric power. Therefore, your whole purpose of having a solar system will not pay off at all. In this very GoodWe inverter review, we won’t highlight the exact or up-to-date price of the GoodWe inverter’s various series but likely to give you an estimate of how much they will cost you.

GoodWe inverters are cheaper in nature and offer a lot compared to its emergence and price. Any decent GoodWe inverter will be around $200 more than a Growatt inverter, but $800 cheaper than the Fronius or SMA inverter. In the light of these figures, any standard inverters’ costs will be around something like these;

Is DC Oversizing supportable by the GoodWe inverter?

Sometimes, you may have to install quite a few panels on your roof to prevent the shading or increase the efficiency. At that time, it becomes troublesome for expanding the size or number of panels as these extra panels will consume most of the efficiency produced by the inverter. On top of that, not all the time, inverters having efficiency mentioned on it should be taken at face value as they are not what they claim.
On the contrary, this highly-caliber GoodWe inverters can withstand the pressure without compromising the efficiency, even when the solar panels are oversized by 33% as per approval of the Clean Energy Council.
 

How can you prevent shading using the GoodWe inverter?

You may have heard of cutting the solar cells into halves for accelerating the power output in an inverter. You also acknowledge that power optimizers can also boost the power output while creating a diversion of the DC current’s route from the shaded areas produced in the solar panels. This, in turn, makes the great use of the electricity produced from the inverter by preventing the shading fallen on the panels. Tigo optimizers, in combination with the GoodWe inverters, are of great use these days according to solar gurus.
 

What kind of warranty does GoodWe inverter offer?

Customers are eligible to get a standard 5 years warranty from the GoodWe Australia; depending on some of the latest inverters, some inverters’ warranty can be extended to 25 years. In that case, the customers first reach out to the installer who was/were accountable for installing it in the first place. However, if the installer or the office is closed/not in touch, you should get in touch with the GoodWe Australia by entering the contact page here and calling them.

This GoodWe inverter review had previously discussed the different ranges of inverters GoodWe produces. For example, the DNS series warranty can be extended to a maximum of 25 years, which is astonishingly phenomenal. To claim this, you can enter the GoodWe Warranty Purchase page to fill up the form to submit it to the proper authority. Both DNS and MS series can come with additional 5 years warranty if you desire so, but to avail it, you must bear in mind that it replaces the ‘parts-only’ between 5th to 10th years, but you have to pay the bills for all the labor costs and taxes/duties.

Any GoodWe inverters above 25kW should have its additional warranty claimed within 6 months of the installation, whereas 2 years for the inverter below 25kW.
 

How do MPPTs contribute to the maximum efficiency?

Most of the GoodWe inverters are equipped with multiple MPPTs, either one, two, or three. If you have maximum MPPTs, they ensure a better electricity yield with less wastage of the power. The advantage of having two solar input is to connect arrays of both east and west-facing roof (if you have any) into one input, leaving another input free for the future possibility of connecting arrays of the other facing roof into that. No matter what time of the day or how inimical the weather is, the MPPT will track the MPP (Multiple PowerPoints) across the solar panels to prevent the shading’s aftermath, hence better efficiency.
