Parallel Connection to 2 PV arrays  
(NTX 4000/5000/6000)

WARNING

When the current from the PV arrays exceeds 17.5 A 
DC (NTX 6000), 14.5 A DC (NTX 5000), 11 A DC (NTX 
4000), when the array power exceeds the limit for 
the single channel (see table in section “10.3 Techni-
cal data”, see page 47, section “10.4 Trip limits/
trip times”, see page 48), or when there is a con-
sistent unbalance of the power between two arrays, 
it is necessary to parallel the two inputs.

When the inverter is configured with parallel input, 
the current to the 2 input terminals: “PV1±” and 
“PV2±” shall be equally distributed in such way to 
limit to 17.5A DC (NTX 6000), 14.5A DC (NTX 5000), 
11A DC (NTX 4000), the current for each terminal. 
To parallel the 2 inputs, 2 AWG 10 cables should be 
used to connect the terminal block PV1- and PV2-, 
and PV1+ and PV2+ (1 black and 1 red cable).

Two MPPTS connection to 2 PV arrays or 4 PV arrays 
(NTX 4000/5000/6000)

WARNING

If the inverter configured as two individual MPPTs 
connect to two PV arrays, the max current for PV 
array shall not exceed 17.5 A DC for each input 
channel (NTX 6000), 14.5 A DC (NTX 5000), 11 A DC 
(NTX 4000).

If the inverter configured as two individual MPPTs 
connect to 4 PV arrays, the max total current for PV 
arrays connect terminals “PV1±” or “PV2±” shall not 
be exceed 17.5 A DC for each input channel (NTX 
6000), 14.5 A DC (NTX 5000), 11 A DC (NTX 4000).

When connect to 2 PV arrays, one array connect 
to one pair of terminals “PV1±” and other pair of 
terminal “PV1±” should be free. The second array 
connect to one pair of terminals “PV2±” and other 
pair of terminal “PV2±” should be free.

Connection to 1 PV array or 2 PV arrays (NTX 3000)

WARNING

If the inverter connect to 1 PV arrays, the max cur-
rent for PV arrays shall not be exceed 17.5 A DC for 
the single input channel (NTX 3000).
