All-in-one solar charge inverter V1.0 19
requirement). The current sharing ports of the inverter cannot be connected to each other. In
addition, make sure that the red and black current sharing connection lines of each inverter are
not manually exchanged, and make sure to tighten the lines with self-contained screws to avoid
the abnormal operation or damage of the system output caused by abnormal parallel current
sharing detection.
For specific wiring, please refer to 2.4.3 Wiring Diagram.
Parallel connection in split phase
: The current sharing detection lines of all inverters
connected to the same phase need to be connected together.
But the current sharing detection
lines of different phases cannot be joined together.
Other connection precautions are the same
as parallel connection in single phase. For specific wiring, please refer to 2.4.4 Wiring Diagram.
7.
Before or after connecting the system, please carefully refer to the following system wiring
diagram to ensure that all wiring is correct and reliable before power on.
8.
After the system is wired, powered on and in normal operation, if a new inverter needs to be
connected, make sure to disconnect the battery input, PV input, AC input and AC output, and
that all all-in-one solar charger inverters are powered off before reconnecting into the system.

1.
The parallel communication line and current sharing detection line of the all-in-one solar
charger inverter need to be locked with screws after connecting. The schematic diagram is as
follows:

In case of parallel operation with multiple inverters, the schematic diagram of parallel
connection is as follows:
