Installing Gateway firmware

In short

If you built your own hardware or need to recover a device, you can install firmware from your browser at svitgrid.app/flash.

Most people never need this. A Gateway bought from Svitgrid arrives ready to use and updates itself.

WiFi configuration

What you need

  • A Chromium-based browser — Chrome, Edge or Opera. Safari and Firefox cannot talk to USB devices.
  • A data USB-C cable. Many charging cables have no data wires and will simply not show the device.
  • A direct USB port, not a hub.

Steps

  1. Plug the device into your computer.
  2. Open svitgrid.app/flash.
  3. Click the button and pick your device from the list.
  4. Wait about 30 seconds without unplugging.

Nothing appears in the device list?

Try a different cable first — that is the usual cause. If it still does not appear, open the case, unplug the USB, hold the BOOT button, plug the USB back in, release BOOT, and flash again.

Your device is not damaged

A failed or interrupted flash cannot permanently break a Gateway. You can always try again.

Flashing wipes the Zigbee network

Installing firmware over USB — and a factory reset — erases the Gateway's Zigbee memory. The network is formed again from scratch, so every smart socket you had paired must be paired again. Your inverter data and history are unaffected.

Flashing only the Zigbee module

A Gateway has two chips, each with its own USB-C port. The main chip runs Wi‑Fi and reads the inverter. The Zigbee module runs smart sockets and reads battery monitors over Bluetooth. svitgrid.app/flash flashes whichever chip the cable reaches.

When the app says your Gateway cannot read batteries yet, flash only the Zigbee module. Wi‑Fi and the link to your station stay as they are.

  1. Plug the cable into the Gateway's second USB-C port.
  2. Open svitgrid.app/flash and pick your device. The page shows Update the Zigbee module?
  3. Click Next, then Flash, and wait without unplugging.
  4. Unplug the Gateway and power it as usual. Once it is back online, you can add batteries in the app.

The page asks how your Gateway connects to the inverter?

The cable reaches the main chip, and flashing it erases Wi‑Fi and the link to your station. Plug the cable into the other port and click Choose another.

Watching what it does

svitgrid.app/logs shows the device's live output over USB in the same browser. Useful for seeing whether it is joining Wi‑Fi, and worth having open if you contact support.
