Sungrow hybrid inverters in Melbourne

Sungrow SH-RS and SH-T hybrid inverters

A Sungrow hybrid inverter does two jobs: it turns the panels’ DC power into the AC your home uses, and it charges and runs a Sungrow battery, now or added later. The SH-RS is the single phase range (SH5.0RS, SH6.0RS, SH8.0RS and SH10RS). The SH-T is the three phase range (SH5T, SH10T, SH15T, SH20T and SH25T), which spreads its output across all three phases.

Every model switches to backup in under 10 ms, is rated IP65 against dust and water, and reports to Sungrow’s iSolarCloud app. What changes with size is how many panels it takes, how fast it charges a battery and how much of the home it backs up.

The inverter must be on that approved list for the system to earn STCs, the federal solar rebate, so check the exact model on your quote. Sungrow Australia’s home range page also names 6 kW, 8 kW and 12 kW SH-T models, but its datasheet and the approved list cover only the SH5T and SH10T.

How STCs work

Earlier and solar-only models: SH-RT and SG-RS

You may already have one of these. The SH-RT (SH5.0RT and SH10RT) is Sungrow’s earlier three phase hybrid. It no longer appears on Sungrow Australia’s hybrid range, but it is on the approved list until 17 December 2027, and Sungrow’s 10-year warranty names the SH5.0RT, SH8.0RT and SH10RT.

The SG-RS (SG5.0RS, SG8.0RS and SG10RS) is Sungrow’s solar-only string inverter: the approved list files it as a “Grid Connect PV Inverter” with no battery port, listed until 7 July 2028. Adding a battery to an SG system means either a battery with its own inverter (AC coupling) or swapping the SG for a hybrid.

Adding a battery to existing solar

What size Sungrow inverter do you need?

Start with your supply. A single phase home takes an SH-RS: every Victorian network pre-approves up to 10 kW of inverter on one phase, so the SH10RS is the largest. A three phase home takes an SH-T, up to the networks’ 30 kW three phase limit, which the SH25T fits within. Battery inverters count toward those totals.

Single or three phase: how to tell

How many panels each model takes

Every Sungrow hybrid can run more panels than its own rating, within two limits under the SAA Technical Requirements (version 1.9, February 2026). Without a battery, the inverter’s output must be at least 75% of the panels’ peak power. With a battery connected, the panels can go past that ratio, but never past the maker’s own maximum.

One catch on the smaller single phase models: Sungrow Australia’s product page headlines a 150% DC/AC ratio for the SH5.0RS and SH6.0RS, which is 7.5 kWp and 9 kWp of panels, lower than the datasheet figures above. An array within 150% sits inside both, so ask your installer which figure the design uses.

Our packages, measured against Sungrow’s limits

Our single phase packages name the inverter by size, not make (see our packages below). Here is how each package’s array sits against the same-size Sungrow:

• 6.6 kWp of panels on a 5 kW inverter (132%): within the SAA ratio, so it works with or without a battery, and within the SH5.0RS’s limit.
• 15 kWp of panels on a 10 kW inverter (150%): past the SAA ratio, so only with a battery connected, and within the SH10RS’s 20 kWp limit.
• 19.8 kWp of panels on a 10 kW inverter (198%): past the SAA ratio, so only with a battery connected, and within the SH10RS’s 20 kWp limit.

More trackers help on a complicated roof. The SH8.0RS and SH10RS have 4 MPP trackers, so panels on several roof faces can each run at their own best voltage; the SH5.0RS and SH6.0RS have 2.

Pairing a Sungrow inverter with an SBR battery

Sungrow’s product pages list its SBH, SBR and SBS050 batteries for the SH-RS and its SBH and SBR batteries for the SH-T. The SBR is built from 3.2 kWh modules, 2 to 8 in a stack (6.4 to 25.6 kWh usable), and up to 4 stacks on one inverter with an extra combiner box.

• The smallest stack has limits. The two-module SBR064 (6.4 kWh) works only with the SH3.0RS to SH6.0RS (single phase) and SH5.0RT to SH10RT (three phase). The SH8.0RS, SH10RS and every SH-T start at the SBR096 (9.6 kWh).
• Charging speed. The inverter charges and discharges a battery at up to 6.6 kW (30 A) on the SH5.0RS and SH6.0RS; 10 kW (50 A) on the SH8.0RS and SH10RS. The SH-T charges at up to 15 kW on the SH5T and SH10T; 30 kW on the SH15T, SH20T and SH25T. The battery has its own rating too, from 3.84 kW (SBR064) to 15.36 kW (SBR256), and the lower of the two sets the pace.
• The rebate. The Cheaper Home Batteries Program needs a battery on the Clean Energy Council approved list. The SBR is listed until 30 December 2026 (BAT-474), so check its status when you book the install.

Backup in a blackout

With a battery connected, every Sungrow hybrid can keep power on in a blackout, switching over in under 10 ms. How much of the home it covers depends on the model:

• SH5.0RS and SH6.0RS: chosen circuits, up to 6 kW.
• SH8.0RS and SH10RS: the whole home, through a 63 A bypass, with a peak of 13.68 kVA for 10 seconds.
• SH-T (SH5T, SH10T, SH15T, SH20T and SH25T): the whole home, 63 A bypass on each phase, and Sungrow supports 100% unbalanced output in backup, so the three phases don’t need equal loads.

How home battery backup works

iSolarCloud monitoring

Every Sungrow hybrid reports to iSolarCloud, on the app and the web: what the panels make, what the home uses, the battery’s charge and any fault codes, with the SH-RS sending fresh data every 10 seconds. Keeping it online matters for more than the graphs:

• Victoria’s emergency backstop. Since 1 October 2024, new and replacement solar systems need a compatible (CSIP-AUS certified) inverter on the CEC approved list and a reliable internet connection. Without internet, a lower export limit applies; if the inverter drops off, exports are automatically reduced until it reconnects.
• The battery warranty. Sungrow’s SBR warranty requires the battery to be monitored in iSolarCloud.
• The Wi-Fi dongle. It counts as an accessory, so Sungrow’s warranty covers it for 1 year from installation, not the inverter’s 10.

If iSolarCloud shows the system offline, the inverter may have lost its Wi-Fi connection, for example after a new router. The reconnect steps are in our monitoring guide.

Sungrow inverter warranty and service in Australia

Sungrow’s inverter warranty runs 10 years from installation in Australia (at most 11 years from manufacture). It names every SH-RS and SH-T model in the table above, the earlier SH-RT and the SG string inverters, and it transfers to a new owner with the original proof of purchase. It is given by Sungrow Australia Group Pty Ltd in North Sydney, the Australian importer for Sungrow Power Supply Co., Ltd.

• Accessories: the Wi-Fi dongle and the smart energy meter are covered for 1 year from installation (at most 2 years from manufacture).
• Extensions: can be bought up to the end of the standard 10-year warranty, as parts only (the replacement part) or standard cover (parts plus Sungrow’s standard freight and labour rebate). They cover the inverter only.
• Claims: start with your installer, who does the first troubleshooting. Then the owner or the installer can lodge Sungrow’s online warranty claim at service.sungrowpower.com.au, with your invoice, receipt or commissioning report; Sungrow recommends finding a local electrician when the installer can’t attend.

The warranty sits on top of your consumer rights: Sungrow’s own terms say its goods come with guarantees that cannot be excluded under the Australian Consumer Law. Full terms: Sungrow’s Inverters 10-Year Limited Warranty.

Sungrow or another brand?

Fronius’s GEN24 Plus is the closest match: a single or three phase hybrid of similar sizes. The practical differences are the battery, the panels and the backup:

• The battery. Sungrow lists its own batteries for its hybrids (SBH, SBR and SBS050 on the SH-RS), and the SBR runs only on a Sungrow hybrid. Fronius names Fronius Reserva, BYD Battery-Box Premium HVS/HVM and LG RESU FLEX for the GEN24 Plus.
• Panels per inverter. The SH8.0RS and SH10RS take up to 200% of their rating in panels; a Fronius GEN24 takes up to 150% (a 5 kW model takes 7.5 kWp, a 10 kW model 15 kWp).
• Blackout backup. With a battery, every SH-T and the SH8.0RS and SH10RS switch the whole home over in under 10 ms. A GEN24 Plus offers whole-home Full Backup too: with a battery and the Fronius Backup Controller, the inverter switches the whole home to backup power automatically, within 10 seconds. Without a battery, its PV Point still gives up to 3 kVA from the panels during a blackout.
