4.3 The Determination of the Installation Method and Position
4.3.1 Mounting Method
Figure 4.1 Mounting method
① The equipment can be installed indoor or outdoor.
② Please install the equipment under the guidance of Figure 4.1. Vertical installation on
floor level is recommended. Mount vertically or tilted backwards by max. 15°. Never install
the inverter tilted forwards, sideways, horizontally or upside down.
③ Considering convenience for maintenance, please install the equipment at a position in
parallel with line of sight.
④ When mounting the inverter, please consider the solidity of wall for inverter, including
accessories. Please ensure the Rear Panel tightly.
Before installation, make sure that the wall has enough strength to hold the screws and bear
the weight of the equipment. Please make sure the equipment is installed properly.
4.3.2 Installation Position
Do not expose the inverter to direct solar irradiation as this could cause power derating due to
overheating. The ambient temperature should be between -40°C ～ +60°C (-40°F ～ 140°
F) 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 on-grid solar
inverters are installed same area, the following safety clearance in Figure 4.2 shall be
followed for proper ventilation conditions.
