Sungrow Inverter Review | Hybrid Solar Inverter

Sungrow Power Supply Co Ltd is deemed the second largest inverter manufacturer in the world just behind the inverter magnet “Huawei.” Having founded in 1997 with little investment, the company now owns an asset worth $1.5 billion. Hence, this content on Sungrow inverter review will show you how the company expanded far beyond than of reaching the community by creating solar inverters to developing the technologies for the power transformation, en-routing the energy source, transitioning energy for the electric vehicles, storing energy, and lastly creating generators for the photovoltaic systems.
 

A Quick Snippet of the History of Sungrow

The journey of Sungrow company didn’t start off like any other typical solar inverter companies, but rather it was quite an ardent story that touched the heart of the founder to feel the necessity to build up this company. The Solargrow was founded by the professor named Cao Renxian, from the Hefei University of Technology in 1997 who oversaw the electrical problem in the remote areas in China, which led him to leave the job, and thus compelled him to inaugurate this company to ensure the better electrical supply through the use of renewable energy.

In the span of 20 years with glory and substantial financial growth, the company remains steadfast in getting all the businesses and customers to stick to the same slogan, which is “Green and Effective.” The company believes that the world can be made greener with the help of its involvement in manufacturing solar accessories.

The company managed to supply its first solar system to its customer who used to be an engineer at Southern Xinjiang railway. Then the company made its first turnover by generating an income of $87,000 in 1998. Since then, the company didn’t have to look back as more solar systems were ordered and purchased from their company. Now the company has a value of $1.5 billion worldwide.

4.8kWh Sungrow home batteryProbably the Best Inverter Battery

The SBP4K8, aka PowCube 4.8 is considered one of the best home batteries for the 5kWh solar system. The high performance of this battery is achieved owing to the contribution made by the Samsung SDI battery module since Samsung manufactures the world’s one of the most sophisticated lithium batteries. Sungrow had teamed up with Samsung SDI in 2015.

The SBP4K8 battery is lightweight and cheap and easy to hold it using the handles shaped into a sturdy cast aluminum lid. The multiple entry points on both sides of the battery make it easy to be linked with other batteries in parallel connection for the higher storage capacity up to 14.4kWh.
 

Customer support when you encountering a faulty inverter

Whenever you encounter an issue with your Sungrow inverter, your first place to call will be your installer who will be responsible for replacing or repairing your faulty inverter as long as the installer is contactable or in business provided that the inverter must be in its warranty period. However, if the installer is not found or no longer in this business, you must lodge a warranty claim with Sungrow.

In that case, Sungrow expects you to find your suitable installer (in some instances, the Sungrow can find you an expert installer) to seek the fault in the inverter. If there is, then the Sungrow will jointly work with the installer to fix or replace the inverter. However, you won’t receive any compensation for arranging your installer and inspect the faulty inverter.

Sungrow Hybrid Inverter

Sungrow hybrid inverter is one of the most unique and demandable solar inverters in the recent era. Although the first model, SH5K+ was released in 2015 with much expectation, it rather seemed like a plain design with not adorned with too many features. However, customers fancied it due to its cheap price despite having no off-grid backup system like EPS (Emergency power supply). However, the EPS box is then launched in the following year to meet the demand of the customers and then finally created hype amongst the customers.

Sungrow Hybrid SH5K-20 Inverter with EPS backup box and Sungrow SBP48K Battery.SH5K+

SH5K+ has garnered its popularity not due to receiving an additional EPS box option to back up the service when the electricity is gone, but rather its sleek, silver, attractive, subtle & fashionable design, and the presence of LCD display are some of the reasons why it managed to lure its customers. This device can be connected to not only 48V lead-acid batteries but also any range of lithium batteries, including BYD, LG Chem, Pylontech, and The Sungrow SBP4K8 flagship battery. Its EPS is capable of backing up with its 3kW power to any basic essential loads, such as lighting circuits, fridges, PCs, and TVs.

New SH5K-30 Hybrid Inverter

This new inverter has a significant feature that has added an extra value to it, which is its built-in EPS box that saves the time and space to install this inverter. Since there is no hassle of extra cable or conduit, it is way safer and easier to install and set up it. This inverter is also blessed with an integrated DC isolator to provide extra protection, as well as save time and money. The ability of the EPS to provide an on-the-spot supply of the electric power is just phenomenal, which takes only 20ms compared with the retro model that would otherwise have taken 3-5 seconds to back up.

SH 5.0/6.0/8.0/10 RT Inverter

The extension of the warranty from 5 years to 10 years has also made it demandable to purchase. However, the only drawback is that this inverter doesn’t run with lead-acid batteries like Pylontech, but the company is working on it to make the inverter compatible with Pylontech.

SH 5.0/6.0/8.0/10 RT Inverter Residential 3-phase Hybrid Inverters

Most of the inverters for the residential properties mentioned in this Sungrow inverter review article are likely to be the single-phase inverters, but thanks to Sungrow for thinking about some of the largest residential properties that require three-phase inverters.

The Sungrow three-phase hybrid inverters are also known as the SH-RT model, which comes with 5.0kW, 6.0kW, 8.0kW, and 10kW power options. However, in Australia, the company is about to initially launch only 5 and 10kW systems followed by 8kW in the near future. These inverters possess a battery with a high voltage rating from 150V to 600V with a charge/discharge rating of up to 10,600W.
