Event message Description
Grid voltage
After switching off, the inverter cannot resume fee-
too high for
ding because the grid voltage exceeds the legally
reactivation
prescribed switch-on value.
 Contact your installer if this error occurs frequently.
Grid voltage Ø The output voltage averaged over the legally prescri-
too low
bed period of time exceeds the permissible tolerance
range. The inverter switches off automatically for as
long as the error state exists.
 Contact your installer if this error occurs frequently.
Grid voltage Ø
The output voltage averaged over the legally prescri-
too high
bed period of time exceeds the permissible tolerance
range. The inverter switches off automatically for as
long as the error state exists.
 Contact your installer if this error occurs frequently.
Grid current
The DC current portion fed into the grid by the
DC offset
inverter exceeds the maximum permissible value.
too high
Due to legal requirements, the inverter switches off
automatically for as long as the error state exists.
 Contact your installer.
Residual cur-
The residual current flowing from the plus or minus
rent too high
inputs to the earth via the photovoltaic modules
exceeds the maximum permissible value. Due to
legal requirements, the inverter switches off auto-
matically for as long as the error state exists.
 Contact your installer.
L and N swapped The live and neutral conductors are wrongly
connected. For safety reasons, the inverter must not
feed into the grid.
 Contact your installer.
PE not
The protective earth is not connected. For safety
connected reasons, the inverter must not feed into the grid.
 Contact your installer.
Insulation
The insulation resistance between the plus or minus
error
inputs and earth is less than the permissible value.
For safety reasons, the inverter must not feed into
the grid.
 Contact your installer.
Fan faulty
The internal fan of the inverter is faulty. In certain situ-
ations the inverter will feed less power into the grid.
 Contact your installer.
Device overhe-
Despite derating, the maximum permissible tem-
ated
perature has been exceeded. The inverter feeds no
power into the grid until the maximum permissible
temperature is no longer exceeded. Check that the
installation conditions are satisfied.
 Contact your installer if the message occurs
frequently.
PV voltage
The input voltage at the inverter is greater than the
too high
maximum permissible value.
 Switch off the DC circuit breaker on the inverter
and contact your installer.
PV current
The input current at the inverter exceeds the per-
too high
missible value. The inverter limits the current to the
permissible value.
 Contact your installer if this message occurs
frequently.
Grid There is no grid voltage present (inverter running
islanding
independently). For safety reasons, the inverter
detected
must not feed into the grid and switches off while
the error is present (dark display).
 Contact your installer if this error occurs fre-
quently.
Time/date lost
The inverter has lost the time settings because it
was disconnected from the grid for too long. Yields
cannot be stored and event messages will have the
wrong date.
 Correct the time under Settings/Time/
Date.

Internal Error
Self test
An error occurred during the self test and the self
failed
test was cancelled.
 Contact your installer if the self test is cancelled
several times at different times of day due to an
error and it is certain that the grid voltage and
frequency were within the limits defined by the
country setting; see section 10.4.

Maintenance

7.1 Maintenance of Solar Frontier SF165-S/SF170-S
photovoltaic modules
A monthly visual check is highly recommended in order to maintain the efficiency
of SF modules and the security of the mounting.
•
Remove any dirt, fallen leaves or bird droppings from the surface, and check
that there is no damage to the surface. Do not use detergent or chemicals
for cleaning dirt off SF modules as it may damage the modules and result in
degradation of insulation.
•
Do not use hard brushes for cleaning. Use only soft cloths to remove dirt from
the modules.
•
When replacement parts are required, be sure the installer/servicer uses parts
specified by the manufacturer with the same characteristics as the original
parts. Unauthorized substitutions may result in fire, electric shock or other
hazard.
•
Stop using SF modules when any damage or unusual phenomena are obser-
ved. Have them immediately replaced or removed by a qualified technician.
7.2 Maintenance DC system
The DC system is maintenance-free. It is still recommended that cables and con-
nectors are regularly checked for signs of damage.
7.3 Maintenance of Turbo inverters
The inverter is basically maintenance-free. Despite this, it is a good idea to regular-
ly check that the cooling fins on the front and rear sides of the device are free of
dust. Clean the inverter when necessary as described below.
Attention
Danger of destruction of components in devices.
• Do not allow cleaning agents and devices to penetrate between the cooling
fins at the front of the inverter (under the grey hood).
In particular, do not use the following cleaning agents:
- Solvent-based cleaning agents
- Disinfectants
- Coarse or sharp-edged cleaning materials
Removing dust
 Dust should be removed using compressed air (max. 2 bar).
Danger
Risk of death by electrocution! Risk of death by electrocution.
Use cleaning agents only with a slightly damp cloth.
 Remove heavy soiling with a slightly damp cloth (use plain water). If necessa-
ry, use a 2% curd soap solution instead of water. After cleaning, remove any soap
residue using a slightly damp cloth.
