Step 1, Mounting The Power Optimizers - SolarEdge SE3000 Installation Manual

IMPORTANT SAFETY FEATURE:
PV modules with SolarEdge power optimizers are safe. They only carry a low safety
voltage before the inverter is turned on.
IMPORTANT SAFETY FEATURE:
As long as the power optimizers are unconnected to the inverter or the inverter is
OFF, the power optimizers will output a safe 1V voltage during installation.
IMPORTANT NOTE:
SolarEdge power optimizers are energized by the PV modules to which they are
connected. String length must not be less than eight power optimizers when using a
single phase inverter and sixteen power optimizers when using a three phase inverte,
or the entire string may shut down. (Please refer to the power optimizer datasheets for
the exact minimum and maximum number of power optimizers permitted in a string.)
NOTE:
Completely shaded PV modules may cause the affected power optimizers to temporarily
shut down. This will not affect the performance of the other power optimizers in the
string, as long as the minimum string length requirement is met when taking into account
the lighted modules only. If under typical conditions modules connected to fewer than
eight optimizers in a single phase system or to fewer than sixteen optimizers in a three
phase system will remain unshaded, add more PV modules.
Step 1, Mounting the Power
Optimizers

Determine the mounting location of each power optimizer. The power
optimizer should be mounted in a place where it can be mounted securely
using both mounting holes. It must also be located near enough so that the
power optimizer can connect to a single PV module. Mark all mounting hole
locations.

Each power optimizer must be attached to the rack using both mounting
holes.

Drill the holes.
CAUTION:
Do not drill through the power optimizer or through the mounting holes. The vibrations
created by the drill can damage the power optimizer and will void the warranty.

Mount one power optimizer at each location using M6 (1/4") screws and
washers.

Verify that the power optimizer is securely attached.
