Finn's Sungrow Batteries Review & Verdict

Finn Peacock has been a Chartered Electrical Engineer since 1998, and is ex-CSIRO

I love Sungrow batteries so much that I bought 12.8 kWh of them myself. They are that rare combination of relatively low price and high-quality hardware with excellent tech support. If you want a battery and buy it at the same time as your solar panels, a Sungrow battery system sharing a hybrid inverter with your panels is very cost-effective. Their 10 kW inverter allows 20 kW of panels with a battery, which is a smart design.

I'm not as keen on Sungrow's software. Their app does everything you need it to do but has a lousy interface and is hard to navigate.

Sungrow Batteries: Pros & Cons

  • Well supported by onshore technical staff
  • Great value
  • High voltage units mean the battery can be separated from the inverter which can help with the legal positioning of the battery
  • Great connectivity between compatible inverters to build bigger systems
  • The new UI on the app looks better
  • Great deal of detail available on the app for electrical nerds & problem diagnosis
  • Easily stackable batteries in robust alloy housings to incrementally increase storage to a whopping 102 kWh
  • Occasionally tech support is snowed under and/or diverts to an answering machine in Japanese

About Sungrow

Sungrow is a giant Chinese company and the world's largest inverter manufacturer. They also make home batteries that are a popular choice here thanks to a combination of affordability and reliability.

Sungrow was founded in 1997 by RenXian Cao, a professor at Hefei University of Technology. He has degrees in electrical engineering and automation, so the boss clearly knows his stuff. Since then, the company has grown enormously but sustainably. Not only do they make products required for the world to switch to renewables, but they've also maintained financial sustainability. In 2022 BloombergNEF gave the company a 100% bankability rating. This means Sungrow is considered financially secure and likely to be around long term.

If a giant utility-scale battery is what you're after, Sungrow can get you one. But what Australian homes and small businesses will be most interested in is the Sungrow SBR HV home battery.

Sungrow SBR HV

Sungrow's current residential battery is the SBR HV. This has stackable battery modules with 3.2 kWh of usable storage each. There's a 3 module minimum and that amount gives 9.6 kWh of usable storage, which will be enough for many households. If you want more, up to 8 modules can be stacked on top of each other for 25.6 kWh. Few households will need that much, but if you want more, up to four stacks can be connected in parallel for over 100 kWh of usable storage.

If you've bought a Sungrow battery stack and want to add more modules, it's relatively easy -- provided you have less than eight. Of course, it's still a good idea to get the amount right at the start so you won't have to pay someone to add more.

Safety

Sungrow uses lithium iron phosphate (LiFePO) battery cells. This is the safest type of lithium battery. But to actually be safe they need to be part of a well-designed battery system. Fortunately, the Sungrow SBR HV does appear to be safe as many have been installed in Australia without issue.

In the past, Sungrow sold the now discontinued PowCube home battery. Despite its alarming name, I'm not aware of any ever going "Pow!" and exploding.

Provided the work was done by a reputable installer, I would have no problem with getting a Sungrow battery installed on my own home. I'd also be fine with one on my parents' home or my brother's. But I'm not sure my sister deserves one.

Cost

A major reason the Sungrow SBR HV is a popular choice is its competitive price. It's a lower-cost battery but reliable enough for us to recommend. You can check out how its cost compares by going to our Battery Comparison Table and scrolling down to "Cost Per Warranted KWh: One Cycle Per Day".

Sungrow Inverter Required

Under normal circumstances, Sungrow batteries will be installed with Sungrow hybrid inverters. Hybrid inverters cost more than standard ones, but Sungrow's are reasonably priced. They also come with a 10 year warranty, which is better than a number of other inverters on the market. Because I haven't heard much in the way of complaints, I assume they're reliable.

Both single-phase and three-phase hybrid inverters are available and Sungrow is one of the few companies supplying hybrid inverters that can provide full three-phase backup.

Because they require a hybrid inverter, a Sungrow battery is often a good choice for homes without existing solar. Alternatively, if there's enough room on the roof, a second solar system with a Sungrow battery can be installed. Another option is to replace an old solar system with one large new one with a battery.

If you have an existing solar system, replacing its inverter with a Sungrow hybrid is also an option. Here's a video of it being done. (Ignore how Finn pronounces "garage" like a New Zealander.) This can require wiring upgrades, so it won't necessarily be a simple task to do.

Fill Your Roof

When a solar system is installed without a battery, the solar panel capacity can normally be no more than one-third larger than the inverter capacity. But when a solar system is installed with a battery this limit can be exceeded.

When a new solar system is installed with a Sungrow battery the panel capacity can be around twice the capacity of Sungrow single-phase hybrid inverters and around 50% more for the three-phase ones. This can be useful for installing large solar systems and I recommend filling your roof with as much solar as you reasonably can.

Flexible Installation

Sungrow batteries are high voltage. This gives installers some flexibility with their location and this helps with meeting Australia's strict fire safety standards.

While they're suitable for outdoor installation, they should be positioned out of direct rain and sunshine.

Backup & Off-Grid Capable

Sungrow battery systems are able to provide backup power. The switchover is almost instantaneous, so there's no temporary power loss. The batteries are also able to charge from the solar panels during the day when the grid is down.

Sungrow batteries are also suitable for off-grid use.

For further specifications and estimated pricing, see Sungrow solar batteries listed on our comparison table.

Installer Recommended

In a vote of confidence for the SBR HV, Sungrow scored 2nd place in SolarQuotes' Installers' Choice Awards 2022 in the budget/best value home battery category. In the SQ 2023 awards for home batteries, Sungrow attained bronze in the best overall battery brand category, gold in the best value battery category, and silver in best after-sales support.

Sungrow is currently listed as an SQ recommended home battery brand.

Sungrow Battery Warranty

The Sungrow battery warranty is better than average. It lasts 10 years or until it has discharged 13,440 kWh per module. Whichever comes first. For most households, it's likely to last the full 10 years. But for households that use the battery at a high capacity factor it will end before then. With a high daily average discharge of 4.8kWh per module the warranty will end after 7 years and 8 months.

The warranty states the battery will maintain a minimum of 60% of its original capacity. This means a module with 3.2 kWh of usable storage when new could drop down to only storing 1.95 kWh and that would be okay according to the warranty. While allowing this much capacity loss isn't good, it is common for lithium battery warranties.

Sydney Office

Their headquarters are in the Chinese city of Hefei, but Sungrow has had a local office in Sydney since 2012. This means they should - hopefully - be able to deal with any warranty issues locally and rapidly. Overall, I'd say Sungrow has good -- but not perfect -- customer support.

Our Sungrow SBR 25.6 battery is working great so far. Some days we get 99% of our electricity from the sun, and on average 95%.

The only time the battery doesn't get us through a 24 hour cycle is if we are running the AC for a long time at night. The lesson is that you need to do your sums when buying a solar battery system. Our AC needs about 7kw per hour of electricity. So, if we run it for 3.5 hours at night it will drain our 25.5kwh battery- and it is a large battery!

You have to be realistic when planning your solar battery system size. You cant expect to go close to "off grid" and run AC, pool heater, pool filter, household appliances etc unless you buy lots of panels, a big inverter and a big battery!

I went probably a bit small on the battery, we may need to increase capacity to cover the winter months better, but I'm happy with the way the inverter controls power flow to it.

The advantage of the Sungrow battery system is that it is modular. I have installed a 12.8kW battery (4 modules) but can continue to add 3.2kW modules to the battery stack at any time without having to rebuild other parts of the solar system.

By opting for a large Sungrow battery stack we have seen major benefits in cost savings, utilising the storage for our Family's heavy consumption and Electric Vehicle Requirements. It's been super reliable and doesn't take up a big amount of room at the side of our house, highly recommended.

SBR 25.6 kWh (8 modules). The claimed 100% depth of discharge appears to be true, with the battery meeting the full houshold load to 0% SOC.
Charges in 2-3 hours on a sunny day with our 10.12 kW PV array; generally fully charged by midday if not earlier.

We have just installed a 19.2 kWh Sungrow battery to complete the system in April 2023.
This is performing very well, and we have not purchased any energy from the grid since installation, it suites our needs perfectly, we run a pool pump approximately 8 hours per day and it is the lowest solar producing period of the year here in Brisbane at the moment, the winter solstice is only weeks away.
We still managed to make a small credit on our account, even with periods of rain and very little sun, picture of consumption and feed in included in review.

Happy with everything so far. Much improved from a previous system. This system is providing all my house power. I love that in a blackout I will have two lights and fridge still on. Safety so I can get around the house without falls.

16 kWh battery seems to be working as expected providing those extra hours of power into the night.

Only had the battery for a few days. but they lasted the first night OK. BEST feature, is that they are modular, comes in 3.2kw packs, we have 3 so 9.6kw. When I can afford it, I just might add another pack or 2 (I believe the extra packs cost approx $2000 + installation). Lasts the night in early summer... not sure it would in winter.

The choice to get a battery was one of the best decisions. It's been working beautifully. We capture a lot so makes sense to store it. In the cool mornings, our ducted reverse cycle AC runs off it for free! We will soon get a hot water heat pump to make further use of the solar. :)

Installed in March last year. x3 battery unit equating to 9.6Kw. Great performance. What we love most is the flexibility of being able to add more storage which is exactly what we did this time round, adding an additional x2 battery unit and bringing the total storage up to 16Kw. More than enough to go completely off grid.

Great system so far even though it is early days, charges to the 100% fairly quickly even on rainy days we have still managed to have the battery charged to full capacity. have not had any issues. We have been monitoring it everyday and are extremely satisfied with the whole system. Looking forward to never or almost never having to have a power bill.
