Error
Errors 010 to 012
Grid under-
voltage 1-phase
Errors 013 to 015
Grid overvoltage
1-phase
Causes
Objects have been deposi-
ted on the heat sink,
obstructing the convection.
The grid voltage of the
injecting phase is too low.
The Solar Inverter monitors
the lower and upper admis-
sible grid voltage limits. If
the voltage drops below the
lower limit (U
min
= 184 V),
the Solar Inverter will auto-
matically switch off and will
only restart when the volta-
ge value rises above the
lower limit again. The shut-
down can already be trig-
gered if the voltage drops
below the lower limit for a
short time.
The grid voltage of the
injecting phase is too high.
The Solar Inverter monitors
the lower and upper admis-
sible grid voltage limits.
Remedies
Remove the objects.
Ask your power supply company about
the stability and design of the grid.
Check the rating of your grid connection
(power meter) or the grid injection
point to your power supply company.
