7. 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 ob-
served. 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 regu-
larly 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 neces-
sary, use a 2% curd soap solution instead of water. After cleaning, remove any soap
residue using a slightly damp cloth.
8. Transport and Storage
Pay attention to all advice on the packaging when storing or transporting SF Power-
Sets. A dry room should be chosen for storage. The packaging is not waterproof.
All electronic components should be kept away from liquids during transport and stor-
age. The SF PowerSets must remain in the original packaging until the installation.
Small amounts of white powder from packaging material may adhere to the mod-
ules. This may safely be ignored and has no affect on performance.
9. Disposal
9.1 Disposal within the EU
This sign on the modules and inverters indicates that these
products must not be disposed of in household waste
when they reach the end of their life cycle.
For disposal and recycling, please take the products to
authorised collection points where you can hand them over
free of charge. Alternatively, in some countries you may
hand them in at the dealer's where you obtain your replace-
ment goods.
Please contact your local authority for further details on
your nearest authorised collection point.
The DC cables can be disposed of at municipal collection points as electric waste.
Penalties may be imposed for violation of the rules depending on the applicable law.
9.2 Disposal outside the EU
The symbol of a dustbin with a line through it is only valid in the European Union
(EU). If you want to dispose of your product please contact your local authority or
dealer to find out the correct disposal method.

*1 Data measured under standard test conditions (STC) defined by the IEC standard
(1000 W/m² irradiance, 25 °C module temperature, AM 1.5 with tolerances of ±10% for
Isc and Voc and +10% / -5% for Pmax). The module efficiency with 200 W/m² irradiance is
typically 98% (±1.9%) of the STC efficiency.
*2 Nominal operating cell temperature (NOCT): Module operating temperature with 800 W/m2
irradiance, 20 °C air temperature, 1 m/s wind speed and in the open circuit condition.
