  If the Hoymiles Inverter's LED flashes red every 1 second, it means the DTU doesn't have an SN and is disconnected from Wi-Fi. Here are some possible solutions: * Check if the distance between the router and the DTU is too far. If it is, move them closer. * Double-check that you entered the correct password for your router during configuration. * Use another device to ensure your router has an effective reception. * Try connecting with a mobile phone hotspot to see if data uploads successfully.
