SAJ is a prominent manufacturer of solar inverters, offering a range of products tailored for the Australian market. Established in 2005, SAJ has developed a strong presence in Australia, providing both residential and commercial solar solutions.
Single-Phase Inverters: The R5 series caters to residential installations, with capacities ranging from 3kW to 5kW. These inverters feature a fanless design for silent operation, dual MPPT trackers for optimal energy harvesting, and a maximum efficiency of up to 98.1%.
Three-Phase Inverters: Designed for both residential and commercial applications, the R6 series offers capacities from 5kW to 10kW. These inverters support higher string currents up to 16A, include built-in AC and DC surge protection devices, and achieve efficiencies up to 98.8%.
Hybrid Inverters: The H2 series integrates solar and energy storage, allowing users to maximize self-consumption and reduce grid dependence. Available in single-phase (5kW) and three-phase (5kW to 10kW) models, these inverters support fast battery charging/discharging and offer multiple smart operation modes.
The SAJ H2 Series Single-Phase Inverter is a high-efficiency solar inverter designed for residential and small commercial applications. It boasts a maximum efficiency of 97.6% with support for up to 200% DC oversizing, allowing flexible system design. With three MPPT trackers, it optimizes energy harvesting from solar panels. The inverter supports ultra-high-power PV modules with a maximum DC input current of 16A per string.
One of its standout features is its UPS function, ensuring seamless backup with a switch time of ≤10ms. It also supports battery storage using LiFePO4 batteries, with a voltage range of 85V to 450V and a maximum charge/discharge current of 50A. The inverter integrates essential safety features such as anti-islanding protection, AC/DC surge protection, and an optional AFCI for arc fault detection.
For connectivity, the H2 series offers Wi-Fi, Ethernet, and optional 4G for remote monitoring via a mobile app and LED display. Its natural convection cooling ensures quiet operation, with a noise level of <35dBA. The robust IP65 rating provides protection against dust and water, making it suitable for outdoor installations.
The inverter supports a wide operating temperature range from -40°C to +60°C, with power derating above 45°C. It meets major international safety and grid compliance standards, including AS4777.2, IEC62109-1 & -2, and EN50549. It comes with flexible warranty options of 5, 10, 15, or 20 years, ensuring long-term reliability.
