SolarEdge SE3000 User Manual

Problem Possible cause and troubleshooting
String voltage is higher than number
of optimizers
WARNING!
If the measured voltage is
too high, the installation
may not have a safe low
voltage. PROCEED WITH
CARE! A deviation of ±1%
per string is reasonable.
Extra power optimizer(s) connected in the string
(not applicable to smart modules).
Check if an extra power optimizer is connected
in the string. If not – proceed to next solution.
A module is connected directly to the string,
without a power optimizer (not applicable to
smart modules).
Verify that only power optimizers are connected
in the string and that no module outputs are
connected without a power optimizer. If the
problem persists, proceed to the next step.
Power optimizer(s) malfunction.
1. Disconnect the wires connecting the power
optimizers in the string.
2. Measure the output voltage of each power
optimizer to locate the power optimizer that
does not output 1V safety voltage. If a
malfunctioning power optimizeris located,
check its connections, polarity, module, and
voltage.
3. Contact SolarEdge Support. Do not continue
before finding the problem and replacing the
malfunctioning power optimizer. If a
malfunction cannot be bypassed or resolved,
skip the malfunctioning power optimizer,
thus connecting a shorter string.
