About This Product

The SAJ 30kW H2 SERIES Three Phase Hybrid Inverter with 3 MPPT is a high-voltage three-phase hybrid inverter designed for larger solar and battery installations. It provides 29.999kW rated AC output for Australian applications and supports up to 45kW of connected PV array capacity. Three independent MPPT trackers, with two PV strings available per tracker, provide flexibility when designing systems across multiple roof orientations or array groups. The inverter also incorporates battery charging and discharging, energy management and three-phase backup functionality in a single unit.

Who This Product Suits

The SAJ H2 30kW is suited to large residential, rural and light-commercial three-phase installations requiring both solar generation and high-voltage battery storage. Its three MPPTs are useful on properties with several roof orientations or electrically separate PV arrays. Dual battery inputs also make the inverter suitable for installations where greater battery capacity or higher charge and discharge capability is required. It is particularly relevant where the system is being designed from the outset for solar, storage and backup operation rather than adding a separate battery inverter later.

Specifications Explained

The SAJ H2-30K-T3-AU provides 29.999kW rated AC output and accepts up to 45kW of PV array power. Its PV input operates across a 180-900V MPPT range, with a maximum DC voltage of 1000V. The three MPPT trackers support two strings each and are rated for up to 40A input current per MPPT. The high-voltage LiFePO4 battery interface operates from 180-800V and provides two battery inputs with up to 50A charging and discharging current per input. Maximum inverter efficiency is 98.0%. The inverter also provides three-phase backup output, including up to 45kVA peak apparent power for 3 seconds, and includes Type II AC and DC surge protection, anti-islanding protection and AFCI protection.

Summary

The SAJ 30kW H2 is a practical choice for larger three-phase solar and battery systems where substantial PV capacity, multiple array orientations and high-voltage storage need to be handled by one hybrid inverter. Its 45kW maximum PV array capacity, three MPPTs, six available PV string inputs, dual battery connections and integrated backup capability give installers good flexibility when configuring larger systems. SAJ combines these functions with app-based monitoring and Wi-Fi/Ethernet communications for ongoing system management.
