4.4.1 Wall-mounted Installation
Procedure
Step 1
Determine the hole positions and mark them using a marker.
Step 2
Secure the mounting bracket.
M6x60 expansion bolts are delivered with the solar inverter. If the length cannot meet the
installation requirements, prepare M6 stainless steel expansion bolts.
The expansion bolts delivered with the solar inverter are mainly used for solid concrete walls. For
other types of walls, prepare bolts by yourself and ensure that the wall meets the load bearing
requirements of the solar inverter.

When drilling holes, avoid the water pipes and power cables buried in the wall.
To prevent dust inhalation or contact with eyes, wear safety goggles and an anti-dust
respirator when drilling holes.
Clean up any dust in and around the holes using a vacuum cleaner and measure the
distance between holes. If the holes are inaccurately positioned, drill a new set of holes.
Level the head of the expansion sleeve with the concrete wall after removing the bolt,
spring washer, and flat washer. Otherwise, the mounting bracket will not be securely
installed on the wall.
