SolarMax 4000P - Connecting the inverter to the PV generator

84
5.4 Connecting the inverter to the PV generator
The inverters of the P series can be operated in single tracking or dual tracking mode,
depending on the conguration of the PV plant. In the dual tracking mode a separate MPP
tracker is available for each DC input (2 trackers). The ex works conguration of the P
series inverters is for single tracking (1 tracker).
Connection conditions
 Connection of maximum 2 conductors (1 conductor in the case of SM2000P /
SM3000P)
DANGER!
Risk of death by fire!
High return currents can cause a re risk for the PV generator.
 When Y plugs are used in order to connect more than 2 conductors (more
than 1 conductor in the case of SM2000P and SM3000P), each DC con-
ductor must be protected individually against dangerous return currents.
 Maximum DC input current: 10 A per DC input / 20 A when operating in single tracker
mode (only SM4000P SM4600P and SM5000P)
 Maximum DC input voltage: 600 V
 Select the conductor cross-section to suit the system conguration.
 Exclusively use Wieland PST40i1C connectors (the mating connectors are not
included in the package supplied)
 Do not t a ground connection to either the negative terminal or the positive terminal
of the PV generator.
Procedure
1. Make sure the DC disconnector and the external AC disconnector are off.
2. Connect the pre-tted DC conductors (A).
3. Use the locking clips (included in the delivery package) to secure the connectors
against manual opening (B).
