Review of Sungrow Solar Inverter

A solar panel with the words sun grow clean power for all.

As mentioned in previous articles comparing solar panels, Sungrow is one of the leading companies in the sector.

Sungrow, founded in 1997 in China, is a multinational technology company specializing in photovoltaic inverters and energy storage equipment for residential, commercial, industrial and utility photovoltaic power plants. It is very oriented towards innovation and the development of renewable energies.

Since hitting the Australian market, it has become one of the favourites for acquiring solar inverters. It has become the second-largest inverter manufacturer in the world, behind Huawei.

Next, we are going to tell you some of the keys to Sungrow investing:

Sungrow Solar Inverter Specifications

  • High-quality construction
  • Up to 98.4% efficiency
  • Great WIFI app
  • Built-in DC isolator, for a neat installation
  • Arc fault detection
  • 10-year product warranty included
  • Elegant design
  • Excellent after-sales support and warranty

Residential Solar Inverters

They have become very popular for their competitive price and reliability.

Their sales show they have become the second best-selling solar inverter in Australia by volume, second only to Fronius (according to Formbay data).

Despite the outdated stigma on Chinese-origin products, Sungrow has an excellent reputation for quality in its products compared to other manufacturers (Chinese or not).

The Sungrow series are lightweight, transformerless string inverters with a wide MPPT voltage range and Wi-Fi communications. Like most inverters, they are cooled by passive cooling, with a sizeable rear heat sink.

With its efficient design, it is not specified to derate below 45 ° C ambient temperature, which is very surprising for a passive cooling inverter.

In addition, Sungrow has hybrid inverters with a modern, sleek, silver design and a simple central LCD screen; it features an additional EPS (emergency power supply) box as a backup and allows the inverter to operate in off-grid mode.

It is one of the most affordable and compatible 48V lead-acid battery hybrid inverters, with a wide variety of lithium batteries and the Sungrow SBP4K8 battery.

As for the backup energy against possible blackouts, it is limited to 3kW. Then it could facilitate the basic functionalities of the house only, such as lighting and some appliances such as refrigerators and televisions. The inverter is not designed for permanent off-grid use.

Monitoring: iSolarCloud APP

Sungrow upholds its motto of always embracing innovation and the latest technologies which is why they include Wifi monitoring as standard on all models. In addition, they feature a modern cloud-based monitoring portal iSolarCloud, a vast improvement over their previous monitoring system.

The new free APP for smartphones is also straightforward and works quite well. It allows you to easily monitor your solar energy system from any device.

Sungrow Solar Inverter Warranty

In this section, we must point out a significant improvement in warranty service by Sungrow.

Previously, all inverters came with a standard 5-year and optional 10-year warranty for specific models. One of its novelties is that it offers a 10-year warranty on most new-generation inverters sold in Australia.

Likewise, it is also worth noting the excellent technical support service of the Sydney headquarters.

Purchasing A Sungrow Solar Inverter On The Sunshine Coast

They already have more than 20 years of experience and are an excellent option for those looking for a reliable and profitable inverter for energy storage or solar energy systems.

In addition, it has the plus of increasing the warranty to 10 years.

Their hybrid inverters, such as the current SHK5-20 inverter, are one of the most popular on the market, although remember that if blackouts are a big problem in your home, it will only be able to power you for essential utilities, not for permanent off-site use.

Furthermore, it must be said that the commercial aspect of its new range is impressive, with modern, silver and elegant models, in addition to including improvements in monitoring inverters with the latest smartphone apps.

In short, they are based on innovation and development, generate good quality/price products, and have become one of the best inverters in the market.
