**Please note battery capacities in this article have been corrected since original publication 1\/8\/2023; however a new range of Sungrow SBH batteries are now available**<\/p>\n

This post is part of our reviews of hybrid solar inverters – which when paired with a battery – can be good Tesla Powerwall alternatives. Here, I’m taking a closer look at the Sungrow SH5.0RS.<\/p>\n

The catchy name SH5.0RS stands for S<\/strong>ungrow H<\/strong>ybrid 5.0<\/strong>kW R<\/strong>esidential S<\/strong>ingle-Phase.<\/p>\n

Compatible With Sungrow Batteries<\/h2>\n

The newest generation of hybrid inverters from Sungrow now pair with high-voltage DC batteries manufactured in-house.<\/p>\n

The SBR series starts with a minimum of two 192volt 3.2kWh nominal bricks (and a spacer to make the stack physically 3 modules high)<\/p>\n

Up to a maximum stack size of 6 (19.2kWh):<\/p>\n

With further expansion of up to four parallel banks of 6 (76.8kWh):<\/p>\n

This stack of bricks can have another 3 stacks added side by side<\/p><\/div>\n

Sungrow also have a new range of SBH high voltage batteries available, with 50amp charge and discharge ratings, which are better suited to larger sized installations than the 30 amp SBR series.<\/p>\n

Easy To AC Couple More Solar Inverters<\/h2>\n

The ability to integrate another AC-coupled solar inverter makes these units much more attractive. You can either have legacy solar on the grid side\u00a0<\/em>or more Sungrow AC-coupled inverters on the backup side of the system.<\/p>\n

This means the extra solar inverter (rated not more than the hybrid) can power loads directly – without bothering the battery. Great news if you want or need more daytime surge capacity. Better yet, the full-rated specifications available with a battery hybrid means you can load a Sungrow with 200% solar. That’s potentially 20kW of panels on the roof with a single-phase connection.<\/p>\n

Ten Year Warranty<\/h2>\n

The warranty is specified as 10 years, and they even offer limited support for off grid<\/a> operation, not that I would recommend it for anything but the most modest<\/a> application.<\/p>\n

If you want to know how Sungrow\u2019s warranty compares with other manufacturers, Ronald has researched Sungrow inverter warranties<\/a> extensively.<\/p>\n

Current & Voltage Ratings<\/h2>\n

The SH5.0RS has far greater surge capacity and is a little more flexible in solar terms than Sungrow’s previous hybrid inverters. As panel wattages trend upward, solar current outputs are going up more than voltages, so the inverters are now given a suitably lower opening voltage window and more importantly, greater current ratings.<\/p>\n

\"\"

While some may claim UNINTERRUPTIBLE Power Supply, there is a well-defined difference between a UPS and an EPS system. So if you have critical applications, a hybrid inverter of any brand or type may not fit the bill. Props to Sungrow for being honest about it.<\/p><\/div>\n

High Voltage Batteries<\/h3>\n

All new generation high voltage hybrid inverters use lower current, so they require much lighter cables from the inverter to the battery, and long cables will suffer less voltage drop. This means the batteries can be placed further away. These advantages come with a small trade-off in the form of an extra layer of complexity (and point of failure) in the battery management system compared to the older low-voltage models.<\/p>\n

Backup Is *In Series* With The Grid.<\/h2>\n

Lighter, cheaper cables become important when you realise that Sungrow (amongst many) wire the Emergency Power Supply through<\/em> the inverter. That means you may need a large and expensive pair<\/em> of cables to run:<\/p>\n
