Error situations and troubleshooting

Internet LED red

Take the following measures:

Check the Internet connection

• Call up any website with a laptop, smartphone or tablet that is connected to the router (via LAN or WiFi). If this is not possible, there is a general fault with the Internet connection.
• If it is possible to access a website but the Internet LED remains red, check the Ethernet or PLC connection.

Checking the Ethernet connection

The aim is to check the connection between the Manager and the router and repair it if necessary.

• Check the cabling between the Manager and router (or network switch).
• Restart all network components involved (router, switch, WiFi adapter, Manager).
• Check whether the Manager can be reached in the local network by entering its IP address in the address bar of the browser.

Powerline Communication (PLC) - Check connector

• Restart the Powerline adapters.
• Establish a new PLC connection. Further information can be foundat here.

Status LED flashing green - update

During the booting of the Manager, the status LED assumes various states. After approx. 2 minutes, the status LED should light up green continuously.

The update starts approx. 5 minutes after the Manager has been connected to the Internet for the first time and is indicated by a green flashing status LED. The duration of the update generally depends on the bandwidth of the Internet connection. The speed of the local network is also relevant. As a rule, the update should be completed within 20 minutes.

Status LED flashing green for longer than 20 minutes

An unstable Internet connection may mean that the update cannot be completed. If the update process takes longer than 20 minutes, proceed as follows:

• Disconnect the Manager from the power supply
• Connect the Manager directly to the Internet gateway (router) via the Ethernet port
• Start the Manager by connecting the power supply

If these steps do not lead to a successful update, please contact SOLARWATT Service.

Inverter is not found and installed automatically

The inverter is not found and installed automatically by the Manager. Possible causes:

• Inverter model is not supported by Autodiscovery
• Inverter is not available in the network
• Inverter is incorrectly configured
• Inverter is not in the same subnet area as the Manager

Inverter model is not supported by autodiscovery

Autodiscovery refers to the automatic finding and installation of devices.

Inverter is not integrated in the network

The inverter is not in the local network and therefore cannot be reached by the Manager. Check the connectivity of the inverter.

Inverter incorrectly configured

Modbus TCP must be activated in the connection settings of the inverter so that it can be recognized and installed by the Manager.

Inverter not in the same subnet area as the Manager

Relevant if the inverter has been manually assigned an IP. This must be in the same class C network area as the Manager.

No data request from the inverter possible

Under certain circumstances, it may not be possible to retrieve data from the inverter despite correct settings. In such cases, restarting the inverter can help. In general, inverters can be restarted by temporarily interrupting the DC and AC voltage. To carry out a restart, please follow the corresponding instructions in the inverter operating manual as a matter of priority.

No or implausible data in the dashboard

Implausible data in the portal can be caused by

• an incorrect assignment of system components within the SmartSetup: Check SmartSetup
• a failure to restart after customer retention: Restart after customer binding
• the inaccessibility of one or more system components.

Check SmartSetup

Call up the SmartSetup and check whether the assignment of the system components or the settings made correspond to your system configuration. Check the following points in particular:

"PV plants" setup step

• Assignment of all inverters to a PV plant
• Assignment of all DC-coupled batteries to a PV plants
• Correct specification of the installed module power
• Setting the consumption-dependent curtailment

Setup step "Home consumption"

A main meter is a mandatory part of every installation. The configuration must correspond to the meter type used and the topology of the domestic installation.

Position between grid and PV plants

• If an ACS (via a Battery flex or My Reserve) is installed, it is automatically defined as a bidirectional meter for the position Between grid and PV plants. This is the only correct configuration if the setup contains a battery system.
• After replacing the Battery flex, you must check whether the corresponding main meter has been selected (identification via the serial number fragment in the name of the Battery flex).

Position Between mains and consumers (consumption meter)

• This meter position may only be selected if this also corresponds to the house installation.
• Only installation meters are required at this position.
• Please note the correct counting direction: The meter must record the electrical power consumed by the household

Assignment of the devices

All devices should be automatically configured on the house side. If a bidirectional meter is installed as the main meter. This applies to the following device classes:

• PV plants
• Consumers

In most cases, this corresponds to the topology of the domestic installation.

Under certain circumstances, however, this automatic allocation may not apply and appliances may therefore be listed under the unbalanced category. In the vast majority of cases, this is not intentional and represents a misconfiguration.

Press the Assign devices automatically button to move all devices to the category Devices recorded by main meter ("house-side") .

Restart after customer retention / during initial commissioning

During initial commissioning, the SOLARWATT Manager flex must be restarted after customer registration, otherwise no data will be displayed in the end customer portal. To do this, disconnect the gateway from the power supply for approx. 5 seconds.

Accessibility System components

Your home installation consists of a PV inverter, a battery storage system and a main meter. If one of the components cannot be reached by the Manager, this can have the following effects:

• no data display in the Manager portal
• implausible data display in the Manager portal

Check the connection status of the devices in the Manager portal(energymanager.com) in the device list. To do this, click on Devices on the start page of the portal to the left of the energy flow diagram:

You will then be taken to the device list:

A functioning connection is indicated by a green bar in front of the respective device name. Red bars indicate a connection error.

To rectify connection errors, first check the accessibility of the device in the network. For devices that provide a graphical web interface, enter the IP address or the host name of the device in the address bar of a browser. The accessing device must be in the same network. If the web interface does not open, follow the operating instructions for the respective device.

In many cases, restarting one or more system components will help:

• of the device in the connection error (inverter, charging station, MyReserve)
• the SOLARWATT Manager
• the components of the network architecture (router, switch, PLC adapter)

Error message: Your main meter is offline

This error message appears if the SOLARWATT Manager does not receive any data from the main meter. Depending on the system configuration, this may have various causes or require measures to be taken.

It is generally recommended that you first acknowledge the error message and continue using the SOLARWATT Manager portal as usual.

If the error message occurs repeatedly and permanently, please take the following measures depending on the main meter used

Error message: Your [inverter] is offline

A faulty connection between the SOLARWATT Manager and the inverter is indicated by a red mark on the "Generation" component in the energy flow diagram of the SOLARWATT Manager portal.

• Restarting the SOLARWATT Manager
• Restarting the inverter
• Restarting the network components
• Checking the availability of the inverter in the local network
