Small and medium-sized enterprises (SMEs) in Australia are facing rising electricity costs, frequent peak charges, and risks from grid downtime. As part of ESG efforts and operational management, many businesses now look to solar battery systems to stabilise energy supply and reduce utility expenses. Unlike residential setups, SMEs often require larger storage capacities to power essential equipment during peak use or blackouts.
This guide offers a professional breakdown of the key criteria to help SMEs select the right solar battery—from residential battery options like Swatten and Deye to larger commercial battery models. We’ll clarify capacity, chemistry, scalability, compatibility, and monitoring—all crucial for savvy business decisions.
We also introduce top-tier options from Solar Rains, present cost-versus-ROI considerations, ensure compliance with Australian standards, and answer real-world FAQs. By the end, business owners should feel empowered to choose a solution that balances performance, growth potential, and financial viability.
Why SMEs Need Solar Batteries
Peak Demand Charge Reduction
SMEs often pay demand charges, which are fees based on peak consumption rates. In the U.S., up to 5 million commercial accounts pay these charges. Using batteries to shave peaks can reduce costs significantly.
Reliability & Resilience
Unplanned outages can cripple SMEs—especially those in manufacturing, hospitality, or retail. Installing a home battery–style system cut power failures and downtime.
Renewable Integration & Sustainability
A solar battery complements PV systems, enabling higher self-consumption and support for corporate sustainability goals. This appeals to environmentally conscious consumers and stakeholders.
Regulatory & Incentive Drivers
Australia’s Clean Energy Council and incentive programs support business-level renewable integration—providing funding and technical guidance .
In summary, solar batteries empower SMEs to manage electricity costs, increase operational stability, and reinforce their sustainable brand image.
Key Battery Criteria for SMEs
Capacity (kWh)
- Recommended size: 10–30 kWh for SMEs with office loads; 30–60 kWh+ if supporting refrigeration or machinery.
- Compare options:
- Swatten Stackable Battery 9.6 kWh ideal for light commercial use.
- Deye 6.14 kWh suitable for small shops or offices.
- Dyness 71–100 kWh caters to higher-need operations like commercial venues.
Battery Chemistry
- LFP (LiFePO₄): stable, long-lasting (6,000+ cycles), safer—ideal for SME applications.
- NMC: higher energy density but slightly less cycle life.
LFP is becoming the Q1 choice due to reliability for business use.
Scalability
- Scalable batteries allow phased investment.
- Swatten offers modular, stackable packs up to 12 units per system.
- Deye stacked modules also scale well up to ~61kWh.
Inverter Compatibility
- SMEs should pair batteries with hybrid inverters to enable off-grid capability and emergency backup.
- Hybrid systems allow round-the-clock power management with export limits.
- Ensure selected battery supports your inverter brand, such as hybrid-ready models from Deye or Swatten.
Monitoring & Control
- Business owners require remote management dashboards and real-time alert systems.
- Choose batteries with integrated apps, alerts for state-of-charge, load events, and fault detection.

Cost vs ROI Considerations
- Typical costs: A 10–30 kWh LFP battery system may cost AUD $8,000–$15,000 including inverter and installation.
- ROI timeframe: Usually 5–8 years, based on electricity rates and peak demand savings.
- Demand charge savings: Smart use of storage can reduce peak costs by 30% or more, cutting total electricity bills by 15–30%.
- Future opportunities: Participation in VPPs or grid support programs may reduce ROI further.
Safety & Compliance
Australia mandates strict compliance for installation:
- AS/NZS 5139: Specifies safety norms for battery systems.
- Essential features: Battery Management System (BMS), over/under-voltage protection, fire/risk mitigation.
- Only reputable suppliers like Solar Rains provide certified systems with Australian warranty and installer support.
FAQs
Small batteries offer 5–15 kWh and suit light commercial use; large batteries (50–100 kWh) power machinery-heavy businesses with high energy draw.
Not for SMEs. Localised systems (10–100 kWh) are effective for savings and resilience, while grid-scale supports national grids.
Correct sizing avoids overinvestment and ensures optimum backup and peak shaving.
Swatten’s stackable battery suits growing needs; Deye is compact and efficient—choose based on current vs. future demand.
Yes, provided the system matches load and is installed by a licensed solar provider to ensure safety and warranty coverage.
Typical lifespan is 10–15 years; LFP systems often exceed 6,000 cycles and benefit from scheduled maintenance.
Conclusion
For SMEs navigating energy challenges and sustainability goals, selecting the right solar battery is essential. Consider capacity, chemistry, scalability, inverter compatibility, and monitoring tools before investment. Products like Swatten stackable batteries, Deye units, and Dyness commercial packs offer various options tailored to business needs.
Smart sizing and usage can deliver ROI in under a decade while improving power security, lowering costs, and supporting ESG goals. Choose certified, reliable solutions and professional installation from service providers like Solar Rains to ensure safety and compliance.
