Which GivEnergy WiFi hardware do you have?
GivEnergy uses different WiFi communication methods depending on the inverter model. Check your serial number prefix to identify which type you have — the setup steps are the same, but the menu layout differs slightly between the WF/WO and WZ dongle variants.
A USB stick that plugs into the port on the underside of the inverter. The most common type on UK residential GivEnergy installations. Applies to AC coupled inverters and Gen 1 hybrid inverters. Serial prefix WE is an older variant also in this category.
Internal WiFi built into the inverter itself. Found in Gen 2 (WG), Gen 3 (WH), All-in-One (WJ), and Giv-Gateway (WK). Accessed the same way — 10.10.100.254 — but requires dipswitches set to WiFi mode inside the bottom cover.
The 4G dongle looks similar to the WiFi dongle but has a SIM card slot visible inside the blue rubber cap, rather than a reset button. It does not require WiFi setup — it communicates via mobile data. This guide does not apply.
Connecting the GivEnergy dongle to your home WiFi
On first power-up, the dongle broadcasts its own WiFi hotspot named after its serial number. You connect to this hotspot, configure the dongle via a browser at 10.10.100.254, then restart it so it joins your home network.
Open WiFi settings on your phone or laptop. You should see a network named after the dongle's serial number — for example WG2049G011. Select it and click Connect (tick "Connect automatically" if shown). If prompted for a password, try your inverter serial number.
While connected to the dongle's hotspot, open Google Chrome (recommended) and type 10.10.100.254 in the address bar. When prompted for login credentials, enter:
In the left-hand menu, click Mode Selection. You will see two options: AP Mode (Access Point) and STA Mode (Station Mode). Select STA Mode and click Apply. This tells the dongle it should connect to your home network rather than act as a hotspot.
Click STA Interface Setting in the menu. Click the Search button to scan for nearby networks. A list of available WiFi networks appears with their RSSI signal strength shown as a percentage. Check that your home network shows at least 60% RSSI — if lower, see the signal strength section before proceeding.
Select your home WiFi network from the scan list. In the Pass Phrase field, enter your WiFi password. Passwords are case sensitive — check for capital letters. Click Apply.
Click AP Interface Setting. Under Security Mode, select WPA2-PSK. Choose a password for the dongle's own hotspot — GivEnergy recommends using the inverter serial number. Click Apply. This prevents others from accessing the dongle's configuration interface.
Click Device Management in the menu. Click Restart. The screen will show "Rebooting" and appear to hang — this is normal. The restart takes up to 10 minutes. After restarting, the dongle leaves AP mode and connects to your home WiFi network. Your device will lose its connection to the dongle's hotspot — reconnect your device to your home WiFi and check the portal after 15 minutes.
Portal went offline after changing your router or WiFi password
Changing your router, WiFi name, or password instantly breaks the dongle's connection — it still has the old credentials. The quickest fix is the SSID rename trick. The full reconfiguration is also straightforward.
If you have just changed your router, temporarily set your new router's WiFi name and password to match your old router exactly. The dongle will reconnect automatically within a few minutes — no reconfiguration needed. You can then change the router name/password and update the dongle at a convenient time.
Wait for the dongle to revert to AP (hotspot) mode — it will do so after failing to connect to the saved network. Power cycle the inverter (AC isolator off for 60 seconds) to speed this up. Once the dongle's hotspot reappears in your WiFi list, follow the full setup steps above with your new network name and password.
All GivEnergy dongles connect to 2.4GHz only — not 5GHz
This is the most common cause of intermittent portal connectivity and failed setup on modern routers. If you have a dual-band router broadcasting both 2.4GHz and 5GHz, you must either disable the 5GHz frequency or give the two bands different network names — otherwise the dongle will attempt to connect to 5GHz and fail.
Minimum signal strength and WiFi extender guidance
Signal strength (RSSI) should be at least 60% for connection — GivEnergy's own troubleshooting guide recommends ≥70% for stable, reliable operation. You can check the RSSI the dongle sees directly from its configuration interface — look at the percentage shown next to your network in the STA Interface Setting site survey. Also note: the dongle requires WPA2 security — WPA3-only networks are not compatible.
Connect to the dongle's hotspot, go to 10.10.100.254 → STA Interface Setting → Search. The site survey table shows each nearby network with an RSSI percentage. Your home network should show 70% or above for reliable connectivity (minimum 60%).
How to factory reset the GivEnergy WiFi dongle
A factory reset is required if you can't access the dongle configuration (unknown credentials, or the hotspot is not visible) and the SSID rename workaround hasn't resolved it.
Remove the small blue rubber cap from the base of the USB dongle. Inside you will see the reset button — a small recessed button next to the USB connector. For built-in WiFi models (Gen 2/Gen 3), the reset button or reset procedure is described in the inverter installation manual. Note: If you have a Gen 3 inverter, contact GivEnergy support before resetting the built-in WiFi.
While the dongle is powered (plugged into the inverter with the AC isolator on), press and hold the reset button for 15 seconds. A pin or straightened paperclip is usually needed to reach the button. The dongle LED will react during the process.
The reset process takes between 5 and 45 minutes — wait at least 20 minutes before attempting to reconnect. If after 20 minutes the dongle's hotspot has not reappeared in your WiFi list, repeat the 15-second button hold. Do not power cycle the dongle during the reset process.
GivEnergy WiFi setup questions
Username: admin — Password: admin. These are the GivEnergy factory defaults. If your installer changed them and you don't know the credentials, try your inverter serial number as the password first. If that doesn't work, a factory reset is the only way to regain access — press and hold the reset button for 15 seconds and wait 20 minutes for the reset to complete.
No — all GivEnergy WiFi dongles connect to 2.4GHz only. If you have a dual-band router, you need to either disable the 5GHz frequency, or give the 2.4GHz and 5GHz bands different names so the dongle can be pointed at the 2.4GHz network specifically. If you're unsure how to do this on your router, contact your internet provider.
Quickest fix: temporarily set your new router's WiFi name and password to match your old router — the dongle will reconnect automatically. If that isn't possible, wait for the dongle hotspot to reappear in your WiFi list (or power cycle the inverter to speed this up), then follow the setup steps above with your new credentials. The full configuration process takes about 10 minutes.
At least 60% RSSI. To check: connect to the dongle's hotspot, navigate to 10.10.100.254 → STA Interface Setting → Search. The site survey table shows each network with its RSSI value. If your network is below 60%, a WiFi extender positioned midway between the router and inverter is usually the fix. The extender's SSID should be a different name from the main router — for example add _EXT to the end.
This usually happens because your device is switching back to a remembered home WiFi network or using mobile data. Fix: go to your WiFi settings and forget all other networks, then turn off mobile data on your phone before connecting to the dongle hotspot. Also ensure you are standing close to the inverter — the dongle's hotspot has a short range. Remember: only one device can be connected to the dongle hotspot at any time, so disconnect any other devices first.
A solid LED means the dongle is connected to your home WiFi, but data may still not be reaching GivEnergy's servers. The most likely causes are: port 7654 is blocked by your router or firewall (the dongle communicates on TCP port 7654 — contact your internet provider if you're unsure); a GivEnergy cloud outage (check givenergy.cloud directly); or a firmware issue. See the GivEnergy portal offline guide linked below for a full diagnostic covering all causes.
