Maximum String Voltage
The maximum length of a single string is dictated by the string voltage, taking temperature
coefficients and the local ambient temperatures into account. For all solarcity installation zones,
the maximum number of panels in a single string of 60-cell modules with a rated output at STC of
less than or equal to 300 Watts, is ten (10). The string length is also limited by the DC isolator’s
rating.
String Inverter Installation
The following section describes the physical installation of the string inverter for solarZero and
solarClassic systems. The range of string inverters is currently limited to two models, a 2kW and a
4kW unit.
5.2.1
Zeversolar Zeverlution 2000s
This inverter is used for systems with a peak output between 1.5kWp and 3kWp (6 to 10 modules),
where the peak performance rating per panel at STC does not exceed 295Wp.
For further details please refer to the
DC Input
The inverter is equipped with a single MPPT input. The single string is connected using
SUNCLIX
connectors
of which one pair is supplied with the inverter.
