Device overview
SAJ R5-5K-T2 is a three-phase grid-tied residential PV string inverter in SAJ's R5 rooftop inverter family. It is best treated as a straightforward on-grid solar inverter for installer-led rooftop systems, not as a hybrid battery inverter, EV charger, gateway, or direct energy meter.
Core inverter fields
The official R5-(3-20)K-T2 manual lists the R5-5K-T2 with 5 kW rated AC power and 7.5 kW maximum PV array power. The same table lists two MPPT trackers with one DC connection set per MPPT, which matters for comparing string-layout flexibility against other mainstream residential inverters.
Installation and phase fit
This T2 model is a three-phase inverter. The manual identifies T as three phase and describes the R5-T2 family as grid-tied three-phase inverters. The inverter is wall mounted, uses an IP65 enclosure, and should be installed and serviced by qualified personnel.
Battery and backup boundary
No native battery or backup-output support was verified for this R5-5K-T2 record. SAJ's manual describes the inverter as feeding AC power directly to the public utility grid and warns not to connect its AC output to private AC equipment. For storage or backup projects, buyers should look at a documented hybrid/storage SAJ platform instead of assuming this grid-tied R5 model can perform that role.
Data and monitoring
The official product page positions R5 around smart monitoring, and the manual documents RS232 and RS485 communication interfaces. SAJ eSolarCloud remains the normal app/cloud ownership path, while local integration claims should be verified against the exact dongle, firmware, and installer configuration used in the project.
Buying notes
The reviewed official page provides product information, downloads, and an online-message route rather than a direct public checkout price. Final availability, warranty handling, and supported regional grid-code variants should be confirmed through SAJ or the local installer/distributor before purchase.
