If the modules are connected in series, the overall voltage may reach high values. When this type of
layout is used, the equivalent voltage is the sum of the voltages of each individual panel. Modules which
are connected in series must have identical current characteristics.
Do not connect different types of modules directly in the same string.
Do not exceed the maximum inverter voltage. The overall voltage must always and, in any case, be less
than the maximum system voltage and lower than the inverter maximum input voltage.
8.1.2 Parallel connections
For applications which require high levels of current, modules can be connected in parallel and the
overall current will be equal to the sum of the currents of each panel.
Parallel connections can only be set if module voltage characteristics are identical. A parallel connection
is allowed for a maximum 3 strings. If the installation requires a greater amount of strings connected in
parallel, then a protective device (e.g. blocking diode or fuse) is required every 3 strings.
