SAJ Electric (Guangzhou Sanjing Electric Co Ltd) was founded in 2005 and manufactures both solar inverters and battery energy storage systems. With 16 CEC-approved battery models in Australia, SAJ has built a notable presence in the Australian residential market, complementing its established inverter business with integrated storage solutions.
SAJ's battery range uses LFP chemistry and is designed to pair seamlessly with their own HS2 and AS hybrid inverter series. The modular battery design allows configurations from approximately 5 kWh to 25+ kWh. SAJ differentiates through its integrated inverter-battery ecosystem, offering a single-brand solution that simplifies installation and support for solar installers.
In Australia, SAJ products are distributed through established wholesale channels, with some distributor-level technical support available. The company has been selling inverters in Australia since approximately 2019, giving it a longer market track record than many battery-only entrants. SAJ appeals to installers who prefer a single-manufacturer solar + battery solution at competitive pricing.

Manufacturers with a strong Australian presence include Tesla, BYD, LG Energy Solution, and Samsung SDI. Look for brands with local support, a warranty track record, and financial stability. Verify warranty support and local service availability for all brands, particularly those newer to the Australian market.
Research: years in Australian market, ACCC recall history, warranty claim experiences (forums/reviews), CEC approval history, and financial stability. Our manufacturer profiles show market data based on these factors. Pay attention to brands with high delisting rates or recall history.
Quality varies significantly by manufacturer. BYD and CATL are large-scale manufacturers that also supply major automakers. However, some lesser-known brands have limited track records. Check CEC approval status, warranty terms, and Australian support availability. Don't choose on price alone. Long-term support matters for a 15-year-plus investment.
