Sungrow is the world’s largest inverter manufacturer by shipped volume, a position they’ve held since 2015. In Australia, independent installer surveys consistently rank Sungrow as the second most preferred residential inverter brand behind Fronius, with roughly 19% of Australian installers nominating it as their go-to choice.
- Two battery ranges: SBR (3.2kWh LFP modules, 6.4 to 25.6kWh, single or three-phase) for most homes. SBH (5kWh modules, 20 to 40kWh) for high-demand properties. Both qualify for the WA Residential Battery Scheme and federal battery incentives under the expanded Small-scale Renewable Energy Scheme.
- Inverter pairings matter: SH-RS (single-phase hybrid) pairs with SBR or SBH (up to 30kWh). SH-RT (three-phase hybrid) pairs with SBR or SBH (up to 8 modules / 40kWh). SG-RS and SG-RT are solar-only string inverters with no Sungrow battery input.
- Available through Perth Solar Warehouse directly and through our Kleenheat Spark partnership. NETCC Approved Seller, SAA-accredited installers, installed from Bibra Lake and Neerabup outlets.
- Sungrow's sweet spot is solid, well-priced hardware without the premium for an extended ecosystem. For integrated bidirectional EV charging and whole-home backup from a single platform, compare Sigenergy or Tesla.
But in 2026, the Sungrow conversation has shifted. Homeowners researching Sungrow are primarily researching their battery systems, the SBR and SBH, and which inverter pairs with which battery. That’s what this guide covers: the complete Sungrow battery and inverter ecosystem, how the pieces fit together, and what it means for Perth homes on the SWIS (South West Interconnected System, aka Synergy) network.
Sungrow is available in Perth through Perth Solar Warehouse directly and also through our Kleenheat Spark partnership. We install Sungrow’s RS-series inverters and both battery ranges. We don’t lead with Sungrow in every quote, but when the brief calls for a well-priced battery system with solid engineering and proven reliability, Sungrow earns its place.
Sungrow offers two residential battery ranges in Australia. Both use lithium iron phosphate (LFP) chemistry. Both are modular. Both qualify for federal and state battery rebates. They serve different homes.
Sungrow SBR
The SBR is Sungrow’s established residential battery. It uses 3.2kWh LFP modules in a floor-standing rack. Start with two modules (6.4kWh) and scale up to eight (25.6kWh) per stack.
Specs that matter in practice: 97% round-trip efficiency, 30A continuous charge and discharge, IP55 for indoor or outdoor installation, 36kg per module (manageable for a single installer), and a 10-year warranty guaranteeing 70% capacity retention.
The SBR pairs with Sungrow’s single-phase hybrid inverter (SH-RS) or three-phase hybrid (SH-RT). For most Perth households running 6.6kW to 10kW of solar, an SBR between 9.6kWh and 16kWh covers evening and overnight loads without oversizing.
Sungrow SBH
The SBH is Sungrow’s newer, higher-capacity battery using 5kWh modules. Configurations from 20kWh to 40kWh per stack, with up to four stacks in parallel for a maximum 160kWh.
Key differences from the SBR: 50A continuous current (versus 30A), higher energy density per module, and a 0.7 C-rate (versus 0.6). The SBH is compatible with both the single-phase SH-RS (up to 6 modules / 30kWh per stack) and the three-phase SH-RT (up to 8 modules / 40kWh per stack). A firmware update released in late 2025 extended SBH compatibility to the SH-RS range.

Sungrow’s inverter range determines which battery you can use. Here’s the decision tree.
SH-RS: single-phase hybrid
Available in 5kW, 6kW, 8kW, and 10kW. The SH-RS is where most Perth homeowners land when they want Sungrow with a battery. Four MPPTs on the 10kW model for complex roof layouts. Accepts DC-coupled SBR batteries and SBH batteries (up to 6 modules / 30kWh) directly, plus AC-coupled options for future flexibility.
The SH-RS manages time-of-use charging through iSolarCloud, supports backup power to essential circuits during grid outages, and handles the charge/discharge scheduling that makes battery economics work on Synergy tariffs.
SH-RT: three-phase hybrid
Available in 5kW, 8kW, and 10kW. The three-phase equivalent, also compatible with both SBR and SBH batteries but with higher module limits. The SH-RT supports up to 8 SBR modules (25.6kWh) or 8 SBH modules (40kWh) per stack, with up to four SBH stacks in parallel for a maximum 160kWh.
SG-RS and SG-RT: string inverters (solar only)
Pairing reference
Inverter | Phase | Battery-ready | Compatible Sungrow battery |
|---|---|---|---|
SH-RS | Single | Yes | SBR (up to 22.4kWh), SBH (up to 30kWh) |
SH-RT | Three | Yes | SBR, SBH |
SG-RS | Single | No | None (AC-coupled third-party only) |
SG-RT | Three | No | None (AC-coupled third-party only) |
SWIS grid compatibility
Every Sungrow system installed in Perth connects to the SWIS network (Western Power manages the infrastructure; Synergy is your retailer). All RS-series inverters are certified to AS/NZS 4777.2 with CEC approval. No compatibility concerns for standard residential installs.
DEBS and battery economics
Synergy’s DEBS pays variable rates for exported solar by time of day. Both the SH-RS and SH-RT support scheduled charging and discharging through iSolarCloud, so you can hold generation during low-value export windows and use it during expensive evening peaks. We configure these schedules during commissioning.
Rebates
Sungrow SBR and SBH batteries qualify for the WA Residential Battery Scheme (state government rebate) and federal battery incentives under the expanded Small-scale Renewable Energy Scheme (SRES). Perth Solar Warehouse is an approved vendor under the WA scheme through PSW Energy.
Sungrow SBR vs. Goodwe ESA: The ESA is an all-in-one (inverter + battery in one cabinet), which means fewer components and lower installation costs. But the SBR paired with an SH-RS offers more inverter flexibility and a proven track record. The ESA wins on integration; Sungrow wins on modularity and field-proven reliability. Goodwe ESA review ›
Sungrow SBR vs. Tesla Powerwall 3: Tesla has the strongest brand and the most polished app. The Powerwall 3 is a fixed 13.5kWh unit with its own built-in inverter. Sungrow offers more granular capacity sizing (6.4kWh to 25.6kWh in 3.2kWh increments) and a potentially lower cost per kWh at larger configurations. Tesla Powerwall 3 review ›
Sungrow vs. Sigenergy SigenStor: Sigenergy offers a premium ecosystem with bidirectional DC EV charging and advanced load management. Sungrow is the value play: proven hardware, competitive pricing, and reliable performance without the ecosystem premium. Sigenergy Sigenstor review ›
Sungrow’s strength is the middle ground. Solid engineering, competitive pricing, and a battery range that scales without locking you into exotic hardware. The RS-series inverters are reliable, the SBR is well-proven in the Australian market, and iSolarCloud does the job.
It’s not the right answer for every home. If you want the most advanced ecosystem with integrated EV charging and whole-home backup from a single platform, Sigenergy or Tesla go further. If you want European-manufactured hardware with passive cooling, Fronius is the pick.
For Perth homeowners who want a well-priced solar and battery system that works reliably, Sungrow is a strong choice.
RS-series inverters: 10-year parts and labour. SBR and SBH batteries: 10-year warranty with 70% capacity retention. Sungrow’s Australian support operates from Sydney.
Perth Solar Warehouse matches every Sungrow warranty with our own workmanship guarantee. One call to Bibra Lake or Neerabup. We handle manufacturer liaison.
Whether Sungrow is the right fit depends on your power supply, your consumption, your roof, and what you want the system to do over the next decade. Request a quote and we’ll recommend the right inverter and battery combination with all rebates and STC discounts included.
