All-in-one solar charge inverter V1.0 17
2.4 Parallel machine wire connection
2.4.1 Introduction
1.
Up to six units connected in parallel.
2.
When using the parallel operation function, the following connecting lines (package
accessories) shall be firmly and reliably connected:
DB15 Parallel communication line*1:
Current sharing detection line*1:
2.4.2 Precautions for connecting the parallel connecting lines
Warning:
1.
PV connection:
When used in parallel connection, different machines need to be connected to different PV
arrays or PV sources.
2.
Battery wiring
:
Parallel connection in single or split phase
: Ensure that all all-in-one solar charger inverters
are connected to the same battery, with BAT + connected to BAT + , BAT - connected to BAT
-, and that the connection is correct with the same wiring length and line diameter before
power on and start-up, so as to avoid the abnormal operation of parallel system output caused
by wrong connection.
3.
AC OUT wiring
:
Parallel connection in single phase
: Ensure L-to-L, N-to-N and PE-to-PE connection for all all-
in-one solar charger inverters, and that the connection is correct with the same wiring length
and line diameter before power on and start-up, so as to avoid the abnormal operation of
parallel system output caused by wrong connection. For specific wiring, please refer to 2.4.3
