5.4.5 Data Logger Connection

Connect the Data Logger to the communication accessory port.
After successful connection, information such as power generation and running state of the inverter can be viewed via
the APP on the phone.

5.5 AC Cable Connection

5.5.1 AC Side Requirements

Before connecting the inverter to the grid, ensure the grid voltage and frequency comply with requirements, for which,
refer to Specification. Otherwise, contact the electric power company for help.
Connect the inverter to the grid only after getting an approval from the local electric power
company.
AC Circuit Breaker
An independent four-pole circuit breaker is installed on the output side of the inverter to ensure safe disconnection from
the grid.

If multiple inverters need to share a circuit breaker, the circuit breaker should be selected according to the capacity.
NOTICE
Never connect a load between the inverter and the circuit breaker.
Multiple Inverters in parallel Connection
If multiple inverters are connected in parallel to the grid, ensure that the total number of parallel inverters does not
exceed 25. Otherwise, please contact CSI Solar for technical scheme.
MV transformer
The MV transformer used together with the inverter should meet the following requirements:
1) The transformer may be a distribution transformer, and it must be designed for the typical cyclical loads of a PV
system (load in the day and no load at night).
2) The transformer may be of the liquid-immersed type or dry type, and shield winding is not necessary.
3) The line-to-line voltage on the LV side of the transformer should endure the outputvoltage of inverter. When the
