Electrical Connection

Safety

Danger to life due to high voltages of the PV array.

When exposed to sunlight, the PV array generates dangerous DC voltage which is present in the DC conductors and the live components of the inverter. Touching the DC conductors or the live components can lead to lethal electric shocks. If you disconnect the DC connectors from the inverter under load, an electric arc may occur leading to electric shock and burns.

Risk of injury due to electric shock.

• The inverter must be installed only by trained and authorized electricians.
• All electrical installations must be done in accordance with the National Wiring Rules standards and all locally applicable standards and directives.

Damage to the inverter due to electrostatic discharge.

Touching electronic components can cause damage to or destroy the inverter through electrostatic discharge.

• Ground yourself before touching any component.

System layout of units without integrated DC switch

Local standards or codes may require that PV systems are fitted with an external DC switch on the DC side. The DC switch must be able to safely disconnect the open-circuit voltage of the PV array plus a safety reserve of 20%.
Install a DC switch to each PV string to isolate the DC side of the inverter. We recommend the following electrical connection:

Overview of the connection area

AC connection

Danger to life due to high voltages in the inverter.

• Before establishing the electrical connection, ensure that the miniature circuit-breaker is switched off and cannot be reactivated.

Conditions for the AC connection

Cable Requirements

The grid connection is established using three conductors (L, N, and PE).
We recommend the following specifications for stranded copper wire. The AC plug housing has the lettering of length for stripping cable..

Larger cross-sections should be used for longer cables.

Cable design

The conductor cross-section should be dimensioned to avoid power loss in cables exceeding 1% of rated output power.
The higher grid impedance of the AC cable makes it easier to disconnect from the grid due to excessive voltage at the feed-in point.
The maximum cable lengths depend on the conductor cross-section as follows:

The required conductor cross-section depends on the inverter rating, ambient temperature, routing method, cable type, cable losses, applicable installation requirements of the country of installation, etc.

Residual current protection

The product is equipped with an integrated universal current-sensitive residual current monitoring unit inside. The inverter will disconnect immediately from the mains power as soon as fault current with a value exceeding the limit.

If an external residual-current protection device is required, please install a type B residual- current protection device with a protection limit of not less than 100mA.

Overvoltage category

The inverter can be used in grids of overvoltage category III or lower in accordance with IEC 60664-1. This means that it can be permanently connected at the grid-connection point in a building. In installations involving long outdoor cable routing, additional measures to reduce overvoltage category IV to overvoltage category III are required.

AC circuit breaker

In PV systems with multiple inverters, protect each inverter with a separate circuit breaker. This will prevent residual voltage being present at the corresponding cable after disconnection. No consumer load should be applied between AC circuit breaker and the inverter.
The selection of the AC circuit breaker rating depends on the wiring design (wire cross-section area), cable type, wiring method, ambient temperature, inverter current rating, etc. Derating of the AC circuit breaker rating may be necessary due to self-heating or if exposed to heat. The maximum output current and the maximum output overcurrent protection of the inverters can be found in section 10 “Technical data”.

Grounding conductor monitoring

The inverter is equipped with a grounding conductor monitoring device. This grounding conductor monitoring device detects when there is no grounding conductor connected and disconnects the inverter from the utility grid if this is the case. Depending on the installation site and grid configuration, it may be advisable to deactivate the grounding conductor monitoring. This is necessary, for example, in an IT system if there is no neutral conductor present and you intend to install the inverter between two line conductors. If you are uncertain about this, contact your grid operator or AISWEI.

Safety in accordance with IEC 62109 when the grounding conductor monitoring is deactivated.

In order to guarantee safety in accordance with IEC 62109 when the grounding conductor monitoring is deactivated, carry out one of the following measures:

• Connect a copper-wire grounding conductor with a cross-section of at least 10 mm² to the AC connector bush insert.
• Connect an additional grounding that has at least the same cross-section as the connected grounding conductor to the AC connector bush insert. This prevents touch current in the event of the grounding conductor on the AC connector bush insert failing.

AC terminal connection

Risk of injury due to electric shock and fire caused by high leakage current.

• The inverter must be reliably grounded in order to protect property and personal safety.
• The PE wire should longer 2 mm than L,N during strip the outer sheath of AC cable.

Damage to the seal of the cover in sub-zero conditions.

If you open the cover in sub-zero condition, the sealing of the cover can be damaged. This can lead moisture entering the inverter.

• Do not open the inverter cover at ambient temperatures lower than -5℃.
• If a layer of ice has formed on the seal of the cover in sub-zero comditions, remove it prior to opening the inverter( e.g. by melting the ice with warm air ). Observe the applicable safety regulation.

Procedure:

1. Switch off the miniature circuit-breaker and secure it against being inadvertently switched back on.

2. Shorten L and N by 2 mm each, so that the grounding conductor is 3 mm longer. This ensures that the grounding conductor is the last to be pulled from the screw terminal in the event of tensile strain.

3. Insert the conductor into a suitable ferrule acc. to DIN 46228-4 and crimp the contact.

4. Insert the PE, N and L conductor through the AC connector housing and terminate them into the corresponding terminals of the AC connector terminal and make sure insert them to the end in the order as shown，and then tighten the screws with an appropriately sized hex key with a suggested torque of 2.0 Nm.

5. Secure the connector body assemble to the connector, then tighten the cable gland to the connector body.

6. Connect the AC connector plug to the inverter´s AC output terminal.

Second protective grounding connection

In case of operation on a Delta-IT Grid type, in order to ensure safety compliance in accordance with IEC 62109, the following step should be taken:
The second protective earth/ground conductor, with a diameter of at least 10 mm2 and be made from copper , should be connected to the designated earth point on the inverter.

Procedure:

1. Insert the grounding conductor into the suitable terminal lug and crimp the contact.
2. Align the terminal lug with the grounding conductor on the screw.
3. Tighten it firmly into the housing (screwdriver type: PH2, torque: 2.5 Nm).

3. Make sure the communication cable and AC connector have been correctly wired and tightened.

Safety code check

After finishing the electrical and mechanical checks, switch on the DC-switch. Choose suitable safety code according to the location of installation. please visit website (www.solplanet.net ) and download the Solplanet APP manual for detailed information. you can check the Safety Code Setting and the Firmware Version on APP.

The Solplanet’s inverters comply with local safety code when leaving the factory.
For the Australian market, the inverter cannot be connected to the grid before the safety- related area is set. Please select from Australia Region A/B/C to comply with AS/NZS 4777.2:2020, and contact your local electricity grid operator on which Region to select.

Start-Up

After safety code check, switch on the miniature circuit-breaker. Once the DC input voltage is sufficiently high and the grid-connection conditions are met, the inverter will start operation automatically. Usually, there are three states during operation:
Waiting : When the initial voltage of the strings is greater than the minimum DC input voltage but lower than the start-up DC input voltage, the inverter is waiting for sufficient DC input voltage and cannot feed power into the grid.
Checking : When the initial voltage of the strings exceeds the start-up DC input voltage, the inverter will check feeding conditions at once. If there is anything wrong during checking, the inverter will switch to the “Fault” mode.
Normal : After checking, the inverter will switch to “Normal” state and feed power into the grid. During periods of low radiation, the inverter may continuously start up and shut down. This is due to insufficient power generated by the PV array.

If this fault occurs often, please call service.

Quick Troubleshooting
If the inverter is in “Fault” mode, refer to Section 11 “Troubleshooting”.
