Independent Mode
In independent mode, the two input areas work independently, as shown in the
following diagram.
To make sure the maximum DC power can be utilized, PV strings
connected to individual input area should have a homogenous
structure, including the same type, the same number, identical tilt and
identical orientation.
Prior to connecting inverter to PV inputs, the following specifications should be met:
Type
Total DC
Power Limit
for Inverter
DC Power
Limit for Each
Input
Open-circuit
Voltage Limit
for Each Input
Short-circuit
Current Limit
for Each Input
SG10KTL 10800W 5400W 1000V 25A
SG12KTL 12800W 6400W 1000V 25A
SG15KTL 15800W 7900W 1000V 25A
SG20KTL 21000W 10500W 1000V 25A
There is a risk of inverter damage! The following requirements should be
met; otherwise they will lead to loss of any or all warranty rights.
y Make sure that the maximum short circuit current of each DC input is less
than the inverter allowable limit.
y Make sure that the maximum open voltage of each string is less than
1000V. Voltage over 1000V can damage the inverter.
