In case the installation site is a level surface, mount the inverter to the
horizontal-mounting bracket to meet the mounting angle
requirements, as shown in the figure below.
Cable binding position
300~
350
mm
Distance away from ground surface ≥ 300mm
Distance away from floating surface ≥ 650mm
(Floating system)
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. In case the inverter is applied in a floating
power plant, ensure that the waterproof connectors are at least
650mm higher than the floating body 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 Installation Clearance Requirements

Reserve enough clearance around the inverter to ensure sufficient space for
heat dissipation. (The fans are maintained on the left side of the inverter, and
a larger clearance is required.)
