5.5 DC Cable Connection
Electric shock!
The PV array will generate lethal high voltage once exposed to
sunlight.
Make sure the PV array is well insulated to ground before connecting it to
the inverter.
There is a risk of inverter damage! The following requirements must be
met. Failure to do so will void guarantee and warranty claims.
 Make sure the maximum short circuit current on the DC side is within
the permissible range.
 Make sure the maximum voltage of each string is always less than
600 V.
 The inverter enters the standby state when the input voltage ranges
between 560 V and 600 V. The inverter returns to the running state
once the voltage returns to the MPPT operating voltage range,
namely, 90 V to 560 V.
5.5.1 PV Input Configuration
-S Series
There is one input area with one MPP tracker. Only one input can be connected,
as shown in the following figure.
