5、 Plug the other input connectors into the corresponding inverter
terminals in the same way.
Notice!




EHE-N1K5TL/EHE-N2KTL inverter has one PV array input.
EHE-N3KTL/EHE-N4KTL/EHE-N4K6TL inverter has two string
PV inputs. The system supports simultaneous connection of
two groups of PV arrays of the same power.
The power of each string of PV array for EHE-N3KTL inverter
shall not exceed 1.65KW.
The power of each string of PV array for EHE-N4KTL inverter
shall not exceed 2.2KW.
The power of each string of PV array for EHE-N4K6TL inverter
shall not exceed 2.53KW.

6.5.2 Inverter Input Parallel Connection
EHE-N3KTL/EHE-N4KTL/EHE-N4K6TL Inverter has two strings PV array input.
System supports input of the two groups PV array which are in the same
frequency.
But some systems may feature a single array. When this is the case, the array
may be connected to the No.1 DC input PV1 section alone provided that array
current is less than the maximum capacity of one section. To avoid possible
problems when determining panel electric insulation parameters, short the
inputs PV1 and PV2.


Parallel method of Inverter internal, just is short the inputs of the second
section (PV2) by connecting a cable to the suitable terminals on the inverter
board. First remove the cover panel of the inverter. How to remove the panel
can refer to “7.2 The Installation and Backout of Cover Panel”.
After remove the cover panel you can find the PV1+、PV1-、PV2+、PV2terminals on the main PCB board as Fig. 6-5. Short the PV1+ and PV2+
terminals with suitable wires, and short the PV1- and PV2- terminals in the
same way, as Fig. 6-5.
