5.2 Connecting PV module
Before installation, check whether your PV modules are suitable for
operation with your photovoltaic solar inverter.
Not all PV modules are suitable for operation with transformerless
photovoltaic solar inverters.
Check with the PV module manufacturer.
5.2.1 Requirements the PV modules have to meet
The ES4200 / ES5000 photovoltaic solar inverters both have two MPP trackers
(each with approx. 50% of the total output of the inverter). Of these, tracker A
has a connection for up to 2 strings and tracker B for one string.
The ES2200 / ES3300 photovoltaic solar inverters have only one MPP tracker
with a connection for up to 3 strings. Both the maximum DC input voltage of
500 V and the maximum input current may not be exceeded.
The PV module connection cables must be suitable for these connections.
A set of connectors for connecting the line ends of a string is included in the
scope of delivery. The type descriptions for other PV connectors are:
– Connection plug: PV-KST4/6II-UR
– Coupling socket: PV-KBT4/6II-UR
