Frequently Asked Questions - S450S Sungrow

How to install the S450S inverter?

The installation must be carried out by qualified personnel only. Wear personal protective equipment (PPE) and follow local regulations. Refer to the user manual available at support.sungrowpower.com.

How to connect the inverter to the WiFi network?

The inverter is equipped with an integrated WiFi module (802.11b/g/n, 2.4 GHz). Follow the instructions in the manual to configure the connection via the app or web interface.

What to do in case of a power outage?

The inverter automatically disconnects from the grid during a power outage for safety reasons. After power is restored, it reconnects after a safety delay.

How to clean the inverter?

Before any intervention, turn off the inverter and wait 30 minutes for it to cool down. Use a dry, non-abrasive cloth. Never use liquid or abrasive products.

What is the inverter's warranty?

The warranty is voided in case of unauthorized opening of the enclosure. Contact your installer or Sungrow for any questions.

Is it possible to use the inverter indoors?

The inverter is designed for outdoor or indoor installation, but must be installed in a ventilated area away from excessive humidity. Follow the instructions in the manual.

How to check the operating status?

DANGER

Lethal voltage!

• PV strings will produce electrical power when exposed to sunlight and can cause a lethal voltage and an electric shock.
• Only qualified personnel can perform the wiring of the PV panels.
• All electrical connections must be in accordance with local and national standards.
• Only with the permission of the local utility grid company, the inverter can be connected to the utility grid.
• Do not open the enclosure at any time. Unauthorized opening will void warranty and warranty claims and in most cases terminate the operating license.
• When the enclosure lid is removed, live components can be touched which can result in death or serious injury due to electric shock.

Lethal danger from electric shock due to possibly damaged inverter

• Only operate the inverter when it is technically faultless and in a safe state.
• Operating a damaged inverter can lead to hazardous situations that can result in death or serious injuries due to electric shock.

WARNING

Risk of inverter damage or personal injury

• Do not pull out the PV connectors and AC connector when the inverter is running. Disconnect the AC circuit breaker. Wait 10 minutes for the internal capacitors to discharge. Verify that there is no voltage or current before pulling any connector.
• Even after the microinverter has been stopped, it may still be hot and cause burns. Wait 30min until the microinverter cools down, and then perform operations on it wearing protective gloves.

WARNING

All the warning labels and nameplate on the inverter body:

• Must be clearly visible.
• Must not be removed, covered or pasted.

CAUTION

Risk of burns due to hot components!

- Do not touch any hot parts (such as the heat sink) during operation.

NOTICE

Only qualified personnel can perform the country setting. Unauthorized alteration may cause:

• A breach of the type-certificate marking.

Risk of inverter damage due to electrostatic discharge (ESD)!

By touching the electronic components, you may damage the inverter. For inverter handling, be sure to:

• Avoid any unnecessary touching.
• Wear a grounding wristband before touching any connectors.

Observe the marks on the terminals when making cables and ensure the polarity is correct. Otherwise, after connecting to the power distribution box, the microinverter may not operate properly, the house's circuit may trip, and it may even result in personal injuries.

Wiring Steps / Procédure de câblage / Verkabelungsschritte / Bedradingsprocedure

1 Connect the external grounding cable.

It is recommended to make a protective ground connection. Lack of protective grounding or unreliable grounding may lead to personal injuries.

2 Connect the DC connectors, make sure there is a PV module connected to PV1.

WARNING

The PV1 channel acts as the host and must be connected with PV module. If it is left unconnected, the system may report a fault and cannot operate properly.

CAUTION

• When connecting the DC connectors, make sure the order of the connectors corresponds properly to the actual positions of PV modules at the site, to facilitate the later setup of the physical layout of the plant.
• If not all of the DC connectors of the microinverter are connected to PV modules, use IP67 waterproof plugs to close off the unused connectors. The waterproof plugs should be prepared by the user.
• If the PV module is located too far away from the microinverter, a DC extension cable is needed. The user needs to make the extension cable first.
• Ensure the PV cables are connected with correct polarity. Otherwise, the microinverter may not operate properly.
  • PV modules cannot be connected in series.

At night, since there is no light, the microinverter in the plant stops working due to the absence of power source. In this case, it does not communicate with the background and its status shows "offline". However, this does not indicate a fault in the device. Once the light conditions return to normal, with stable power source, the microinverter will start up and work again. It will then communicate with the background normally and its status will be "online". If the device stays offline for a long time or in case of other abnormal symptoms, inspect the device and its network connection.

Choose the "Device" tab on the top of the screen to check the devices in the plant and their status.

If a microinverter in the list remains offline for an extended period (excluding the situation that the microinverter goes offline at night, which is normal), follow the troubleshooting steps below.

1. Check that the home router network is functioning properly.
2. Check that the microinverter is using the correct password to connect to the network.
3. Determine if the signal is weak because the microinverter is too far from the router. If necessary, add a Wi-Fi extender between the microinverter and the router.
