SAJ AS3 Three-Phase All-in-One Solution 10 kW IP65 *BE*

The SAJ AS3 is a compact, three-phase inverter designed for modern energy and photovoltaic applications. The series covers power ratings from 3.0 to 12.0 kW, making it suitable for a range of system sizes in residential and small commercial applications. Models are available with rated AC power outputs of 3, 4, 5, 6, 8, 10 and 12 kW, amongst others.
The inverter supports 100 per cent three-phase voltage asymmetry and features an integrated backup output to supply connected loads in the event of a mains failure. Depending on the power class, the respective inverter rated power is also available at the backup output. Significantly higher peak powers are possible for short periods.

With a maximum efficiency of up to 98 per cent, the AS3 series enables efficient energy conversion. The power factor is adjustable within the range from 0.8 capacitive to 0.8 inductive, whilst the total harmonic distortion (THDi) is below 3 per cent.

Numerous protection functions are already integrated to ensure safe system operation. These include overload protection, AC short-circuit protection, overcurrent protection, overvoltage protection, anti-islanding protection and Type II AC overvoltage protection.

Communication is provided as standard via Wi-Fi and Ethernet, with 4G available as an option. Operating information can be accessed via the LED display and the accompanying app.

Thanks to its IP65 protection rating, natural convection cooling and an operating temperature range of –30 °C to +50 °C, the SAJ AS3 is designed for flexible use. The noise level is below 35 dB(A). With dimensions of just 450 × 695 × 170 mm and a weight of approx. 32 kg, the inverter also features a particularly compact design.
