4.2.3 Angle Requirements
Install the inverter vertically or at the maximum allowable rear tilt angle. Do not install the in-
verter horizontally, forward, excessively backward, sideways, or upside down.
Please consult SUNGROW before tilting backwards the inverter and install it in floating
power plants.
In case the installation site is a level surface, mount the inverter to the bracket to
meet the mounting angle requirements, as shown in the figure below.
Take the following items into account when designing the bracket scheme:
• Consider onsite climate conditions and take anti-snow and anti-rain measures
if necessary.
• Ensure that the waterproof connectors are at least 300mm higher than the
ground surface.
• Bind the cables at the positions 300~350mm away from the DC connector, AC
waterproof terminal, and communication waterproof terminal.
• The various waterproof terminals should be tightened in accordance with the
torque requirements in this manual to ensure that they are tight and sealed.
Contact SUNGORW if you have any question.
4.2.4 Clearance Requirements
Reserve enough clearance around the inverter to ensure sufficient space for heat
dissipation.
