        Frequently Asked Questions

        The Fronius Datamanager interface can be accessed by typing “http://datamanager” in your browser search bar, or via IP address 169.254.0.180 for the LAN interface, via IP address 192.168.250.181 for the WLAN Access Point. This is accomplished only when a computer or smart device is connected directly to the access point of the inverter..
        The Datalogger ID is a number that always begins with “240.”.  It is important to note that your datalogger ID may be missing a digit if the ID was read from the inverters display directly. Datalogger IDs can be 7 digits long and should be read from the Datamanager interface screen or from the list of available networks on your smart device once the access point is activated. Make sure this ID matches the ID your Solar.web page.
        The most common solutions to this are to firstly restart the inverter via AC and DC reset. Check to make sure there is a Datamanager card installed and check that the Solar.net ring is complete. If the ring is not complete, a red LED representing the “X” symbol will show on the card and the access point will be unavailable.
        Regarding DC:AC ratio, each inverter can be oversized by 50% except for the Fronius Symo 208 15.0kW inverter which can be oversized by 40%. Care should be taken with respect to the maximum open circuit voltage of the inverter, as well as the maximum short circuit current. System design exceeding these limits is against the terms of warranty.
        Dynamic IP addresses can change each time the Datamanager connects to the internet. This is a common practice in networking and is used when the IP address of the inverter is not needed to be known. Most consumers and residences use dynamic IP addresses for their networking needs. Static IP addresses are necessary under circumstances where customers have large networks and individual IP addresses need to be known for proper networking.
        It can sometimes be necessary to port forward 49049 UDP to bypass firewall issues with the gateway or Internet Service Provider. This port is essential to outbound information to the Solar.web servers and must have a viable connection to outbound data.
        Each LED corresponds to a specific symbol and state of the Datamanager card. The Check symbol represents power is being supplied to the card. The Antenna symbol indicates that the Datamanager card is connected wirelessly to a router. The Globe symbol represents the link between the Datamanager card and the Internet. Lastly, the “X” symbol indicates a viable connection in the Solar.Net ring. A red LED indicates the absence of its respective symbol.
        Installers are responsible for the research and implementation of their Rapid Shutdown equipment. Our Fronius Primo line can be paired with IMO FireRaptor PV isolating equipment. APsmart rapid shutdown is commonly paired with the Fronius Symo Advanced inverter which features the power line communicator.
        The Fronius Solar.creator tool is versatile and allows you to size a system appropriately with in-depth parameters. Watch the linked video for a quick overview or watch a training on-demand here.   
         
        The state code 240 indicates an active arc on the PV array that was detected by our Arc Fault Circuit Interruption Algorithm. This arc can be found in any connection point of DC lines coming from the modules. It is important to examine every connection point for an excellent bond and check all torques on electrical lugs.  The addition of 3rd party devices to the PV array adds more connection points that have the potential to arc.
