Do not expose the inverter to direct solar irradiation as this could cause power
derating due to overheating. The ambient temperature should be between -25°C
～
+60°C
（
-13° F
～
140° F
）（
This temperature range is not equivalent to the
temperature range required by the battery pack
）
to ensure optimum operation.
Choose locations with sufficient air exchange. Ensure additional ventilation, when
necessary.
To make sure the installation spot is suitably ventilated, if multiple SAJ grid-tie
