Sungrow SBH: 35kWh [HV Battery]
Sungrow SBH: 35kWh [HV Battery]
The Sungrow SBH is a next-generation high-voltage modular Lithium Iron Phosphate (LFP) battery system designed for homes with higher energy demands. Using 5 kWh modules — larger than the SBR’s 3.2 kWh — the SBH delivers more power in fewer stacking positions, with a higher continuous current of 50A compared to the SBR’s 30A. This 35 kWh configuration (SBH350) uses 7 × 5 kWh modules with a nominal voltage of 492.8 V, delivering 100% usable energy and a round-trip efficiency of 96–97%. With IP55 rating, 10-year warranty with 70% capacity retention, and CEC approval, the SBH is suited for large residential and light commercial energy storage in Australia.

Key Benefits
| Benefit | What It Means for You |
|---|---|
| 10-Year Warranty (70% Capacity) | Higher minimum end-of-warranty capacity guarantee than many competitors — 70% vs. the typical 60%. |
| 100% Usable Energy (DOD) | The full 35 kWh of stored energy is available to power your home. |
| High 50A Continuous Current | Significantly more discharge power than the SBR (30A) — ideal for homes with EV chargers, pool pumps, and air conditioning. |
| 96–97% Round-Trip Efficiency | Among the highest round-trip efficiencies in residential storage — more solar energy returned to your home per cycle. |
| 5 kWh Modules | Larger modules mean fewer components, faster installation, and a more compact footprint for the same capacity. |
| IP55 Rated Enclosure | Suitable for indoor and outdoor installations across all Australian climate zones. |
| iSolarCloud Integration | Full monitoring and management via Sungrow's iSolarCloud App — live data, remote control, and alerts. |
Premium Performance for High-Demand Homes
The Sungrow SBH 35 kWh system is engineered for homes that need more — more capacity, more power, and more flexibility. The 50A continuous current rating means the SBH350 can deliver approximately 24.64 kW of instantaneous power from this 7-module stack, making it suitable for large homes or light commercial sites with multiple simultaneous loads such as ducted air conditioning, EV charging, and pool systems. The 96–97% round-trip efficiency helps maximise the usable solar energy returned to the home over time
Advanced LFP Architecture at Scale
The SBH operates at a nominal voltage of 492.8 V with an operating voltage range of approximately 415.8 V to 562.1 V, making it suitable for Sungrow three-phase hybrid inverter applications. Like the rest of the SBH range, it uses Lithium Iron Phosphate prismatic cells with a multi-layer Battery Management System (BMS) providing protection against over-voltage, under-voltage, over-current, and temperature extremes. Natural convection cooling ensures silent and low-maintenance operation.
Designed for Expansion and Long-Term Value
The modular architecture allows the SBH system to grow with energy demand. The SBH350 starts at 35 kWh with 7 modules, with support for up to 8 modules per stack (40 kWh). Up to 4 systems can be connected in parallel, allowing a total system capacity of up to 160 kWh. This provides a scalable solution for large homes and small commercial applications without changing the core platform.

AS/NZS 5139 Compliance Positioning
| Compliance Area | Positioning |
|---|---|
| Battery Chemistry | Uses Lithium Iron Phosphate (LFP) chemistry, widely regarded as a safer and more thermally stable battery technology for residential energy storage applications. |
| Installation Environment | Suitable for indoor or outdoor installation subject to site-specific assessment, required clearances, and installer compliance with AS/NZS 5139 and all local electrical and building requirements. |
| System Protection | Includes battery protection functions such as over/under voltage, over current, and over/under temperature monitoring, supporting safe system design when installed correctly. |
| Mounting Requirements | Floor-mounted configuration with wall fixing of the top module supports secure installation, but final compliance depends on the certified installer's site design and mounting method. |
| Location Assessment | Final placement must be assessed against AS/NZS 5139 requirements for exclusion zones, egress paths, habitable rooms, windows, doors, vents, and nearby ignition sources. |
| Installer Responsibility | Compliance with AS/NZS 5139 is determined by the complete installed system, not the battery alone. Installation must be completed by a suitably licensed and accredited installer. |
| Australian Market Suitability | CEC listing and relevant product certifications support suitability for Australian residential installations, subject to compliant system design and installation practices. |
Important: Product features and certifications support compliant installation outcomes, however final AS/NZS 5139 compliance is site-specific and must be confirmed by the installer based on battery location, mounting surface, clearances, barriers, ventilation, and the overall system design.
