Description
SAJ ATS1-T63-A is a three-phase automatic transfer switch panel for whole-home backup with SAJ H2, HS2 and HS3 three-phase hybrid systems. It switches the backup loads between the grid and the backup output of the inverter in 50 ms, in automatic or manual mode. Its rated current is 50 A; its maximum current is 63 A at ambient temperatures up to +30 °C.
SAJ ATS1-T63-A
Switching time 50 ms between the grid and the backup output of the inverter, in automatic or manual mode.
Rated current 50 A; maximum current 63 A at -25 to +30 °C, falling gradually from 63 A to 50 A between +30 and +45 °C.
Grid phase-loss protection: when one grid phase is detected as disconnected, the panel switches to the backup output of the inverter and back to the grid when the phase has recovered.
IP54 enclosure for indoor or outdoor installation, 15.8 kg, natural convection cooling.
Ports for grid, inverters and two load groups.
The panel has AC connections for the grid, for the backup output and the on-grid output of the hybrid inverter, for an on-grid inverter, for the smart load and for the backup load. When the grid is out, the backup loads are supplied from the backup output of the inverter and the loads on the smart-load port are no longer supplied. Each inverter and load connection needs a circuit breaker, five in all, selected for the rated current of the connection and installed in the panel or in the external distribution box; the circuit breakers are not part of the package.
Control in the elekeeper app with the eManager module.
With the eManager module installed in the panel, the transfer switch is controlled and monitored in the elekeeper app. The module connects to the hybrid inverter over RS485 or LAN, depending on the inverter model. The app sets the phase-loss protection, which is enabled by default, and the remote off-grid switching, which is disabled by default.

Product questions
What current does the ATS1-T63-A carry?
The ATS1-T63-A has a rated current of 50 A and a maximum current of 63 A. The maximum current of 63 A applies when the ambient temperature is between -25°C and +30°C. Between +30°C and +45°C, the maximum current decreases gradually from 63 A to 50 A.
Which circuit breakers does the installation need?
The installation requires five circuit breakers, one for each of the following connections: Inverter Backup, Hybrid inverter Grid, On-grid inverter Grid, Smart Load, and Backup Load. Select applicable circuit breakers based on the rated current of the target connections. The circuit breakers can be installed inside the ATS Box or in the external distribution box of the users.
Where can the panel be installed?
The device can be installed either indoors or outdoors. Do not install the device in resting areas, such as bedrooms, because the noise level may exceed 30 dB when the grid is unstable.
