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.
AVERTISSEMENT!
Si la tension mesuree est
trop haute, la tension basse
de securite pourrait manquer
dans l’installation.
REDOUBLEZ DE
PRECAUTION. Une deviation
de ±1% par string est
raisonnable.
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.
