About This Product

The SAJ 15kW H2 SERIES Three Phase Hybrid Inverter with 3 MPPT is a 15 kW three-phase hybrid inverter designed to manage solar generation, high-voltage battery storage and backup power within one system. The H2-15K-T3-AU provides three independent MPPT trackers, allowing installers greater flexibility when working with multiple roof orientations or electrically separate PV arrays. It supports up to 30 kW of connected PV array power and is designed for use with compatible LiFePO4 high-voltage battery systems.

Who This Product Suits

The SAJ H2-15K-T3-AU suits larger three-phase residential installations and light commercial systems requiring both solar and battery capability. Its three MPPT trackers are particularly useful on properties with panels spread across different roof orientations or array sections. It is also suitable where backup capability and provision for substantial battery storage are part of the system design.

Specifications Explained

The inverter has a rated AC output of 15 kW and supports up to 30 kW of PV array power. Its three MPPT trackers each support two PV strings, with a 180-900 V MPPT operating range, 600 V rated DC voltage and 1000 V maximum DC input voltage. Battery operation supports LiFePO4 systems across a 180-800 V battery voltage range with two battery inputs. Maximum efficiency is 98.0%, while backup output is rated up to 15 kVA with short-duration peak output up to 22.5 kVA for 3 seconds. Integrated protection includes anti-islanding, AFCI, AC short-circuit and battery reverse-polarity protection, along with Type II AC and DC surge protection. Monitoring and configuration are provided through LED indication and the SAJ app, with Wi-Fi and Ethernet communications supported.

Summary

The SAJ H2-15K-T3-AU combines a 15 kW three-phase solar inverter, high-voltage battery interface and backup functionality in a single unit. SAJ has equipped this model with three MPPT trackers, substantial PV input capacity, dual battery inputs and integrated system protections, making it a practical option for larger three-phase solar and storage installations where flexible array design and future energy storage are important.
