Installation Envioronment

Delivery List

Inverter Installation

• 4 holes with 70 mm hole depth should be drilled by φ10mm drill according to the position of holes on the wall hanging backplane.

AC Output Line Installation

• 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.

1. YJV copper line or YJVR copper line are recommended for using.
2. For the use of aluminum wire, please contact with the Service Department of Solplanet.
3. The digital scale of the connector housing can be used as the wire stripping length reference.

• A: Applicable outer diameter of the cable for part 1: 20-24mm;
• B: Applicable outer diameter of the cable for part 2: 24.5-30mm;

Note: Part 1 should be removed when the outer diameter of the cable is greater than 24 cm.

Dc Input Line Installation

• 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.

Communication Line

• 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.

COM1 &COM2: RS485(selective assembly)

COM3: WiFi/4G Cat1

• 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.

Startup Operation

• 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.

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.

EU Standards Conformity

• The EU Standard Directive covers the following contents:
• Electromagnetic Compatibility Directive 2014/30/EU (L 96/79-106, March 29, 2014) (EMC)
