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.
