Electrical connection should comply with national/regional installation regulations.
It is required to ensure that all DC switches and AC circuit breakers are disconnected before
establishing an electrical connection, or the high voltage in the inverter may lead to electric shock
hazard.
The inverter should be reliably grounded (PE) as required in order to connect the inverter to
the grid for working according to the requirements of safety regulations.
The inverter will report a PE grounding error when the grounding (PE) is poor or the live wire
grounding (PE) of the power grid occurs. In this case, the inverter should be check to ensure that
it is reliably grounded or contact with the Service Department of Solplanet.
The photovoltaic module should be ensured well insulated from the ground.
The maximum open circuit voltage of the photovoltaic module shall not exceed the maximum DC
input voltage of the inverter according to the coldest weather conditions recorded at the site of
the power station.
The polarity of the photovoltaic module connection cable should be checked.
The DC switch should be ensured to be turned off.
It is prohibited to remove or insert DC connector when the inverter is loaded.

1. COM1&COM2: RS485(selective assembly)
2. COM3: WiFi/4G Cat1
1. Close the AC circuit breaker between the inverter and the power grid.
2. Close the DC switch.
3. The inverter will start automatically when the dc input voltage and grid conditions meet the requirements of
grid-connection.

It is only applicable the Company’s products, and cannot be connect to other USB devices.
See the data acquisition stick user manual for the connection procedures.
Check whether the inverter is grounded reliably.
Check whether the ventilation around the inverter is good.
Check whether the AC voltage on the power grid side is within the permitted operating range of
the inverter.
Check whether the vacant DC connector input terminal/communication terminal on the inverter is
reliably.
Communication cables and power cables should be separated for running and large interference
sources should be avoided to prevent signal from interfering.
CAT-5E or higher-level shielded cables should be adopted as RS485 communication cables
between inverters. The pin allocation at both ends of the cable should comply with EIA/TIA568B
standards. UV-resistant cables should be used when it is used outdoors.
The total length of RS485 communication cables should not exceed 1000m.
