Monocrystalline solar modules   Monocrystalline solar cells have an extremely regular crystal 
structure which arises through the controlled cooling of 
liquid, pure silicon. Monocrystalline cells are easily identied 
by the separate disks and their black colour.
MPP tracker   Maximum Power Point Tracker; allows the inverter to use the 
largest possible output from the photovoltaic modules under 
various conditions.
MPP voltage  DC solar voltage (V) supplied at the maximum output.
Open circuit range   Open terminal voltage of a solar module/solar string. The 
voltage is measured across the photovoltaic connection, 
which means there is no load across the solar modules.
Overcurrent fuse   A protective device in the supply part of an electrical system. 
The circuit breaker disconnects the electrical circuit when the 
current entering the system becomes too high.
Photovoltaic connection   Connection for the solar modules, generally via an MC4 
connector.
Polycrystalline solar modules   Polycrystalline solar cells (also known as multicrystalline). 
Like monocrystalline cells, except that the effectiveness of 
these cells is generally somewhat lower and they are dark 
blue in colour.
Port 80   The port on an internet router which the PowerRouter uses to 
communicate with the Nedap web server.
RJ45 connector  Plastic connector with 8 contacts.
SOC  State of Charge of the battery.
Software Installation Tool   The Software Installation Tool not only enables you to initiate 
the PowerRouter, but also to make extensive changes to the 
settings or provide the PowerRouter with the latest rmware. 
Temperature sensor   Sensor which is installed on the battery. Measures the 
battery temperature to protect the battery and optimise 
charging.
Thin-layered or amorphous modules   A layer of amorphous silicon is deposited over a . This is 
known as the thin lm method. Since relatively small amounts 
of silicon are used, the effectiveness of this method is lower 
than with crystalline modules, but it costs considerably less.
