Summary
With a long history of manufacturing renewable power systems and very good feedback from our network of solar installers, Sungrow is an excellent option for those wanting a reliable, cost-effective inverter for solar or energy storage systems. This is further reinforced by the 10-year warranty now standard on most next-generation inverters. For residential rooftop systems, the Sungrow SG series inverters have become a popular choice, and the new and improved IsolarCloud online portal makes monitoring and firmware upgrades easy.
On the commercial side, the range of CX string inverters not only looks impressive but has a long list of standard features, including smart active cooling systems, inbuilt IV curve scan, PV over-sizing up to 150%, PID recovery, and 12 x MPPTs on the new SG110CX-P2 model, making them some of the most advanced inverters on the market.
Regarding battery storage, the slick new SH-RT and SH-RS series hybrid inverters and high-voltage modular SBR and SBH battery systems are a powerful and affordable combination with instantaneous backup power, making it a reliable option for households requiring backup power. Additionally, the SH series hybrid inverters feature some of the most advanced diagnostic tools and innovative PID recovery technology to reduce the common problem of panel PID degradation. For larger energy storage requirements, Sungrow offers a range of utility-scale energy storage systems and is looking to become one of the industry leaders in this space.
Personal Experience
As for my direct experience, I have designed and installed numerous Sungrow grid-tie and hybrid systems over the last six years and have been impressed with their performance and reliability. Of all the systems I have been involved in, I have not experienced any failures or issues requiring a warranty or replacement. The only problems have revolved around commissioning and online cloud connection, which is common with any solar inverter. However, the most notable improvement has been in the iSolarcloud monitoring system, which is very easy to use. The updated, user-friendly platform has streamlined the installation and commissioning process. It also offers a vast array of tools and information, enabling remote diagnostics, firmware upgrades and enhanced monitoring.
