If the dongle LED is solid and your home WiFi credentials are saved, but the portal still shows no data — the cause may be upstream: dongle hardware, firmware, cloud outage, or port 7654. The portal offline guide covers all of these.

Brilliant support to get my solar battery working again. I didn’t expect help on a Saturday but Ron answered the phone, listened and sent me the information I needed to get it going, answered questions etc. A brilliant service I’d happily recommend.
Ron was brilliant. He really tried to help. He spent hours trying to fix our GivEnergy AIO and ultimately it became apparent that it needed parts to fix the BMS management system. As there appears to be no replacement parts available on the market, he gave excellent advice on what options are now available to move forward. He is incredibly helpful and knowledgeable.
Called back within a day and gave good advice.
Ron was extremely helpful and tried his best to repair/reset our GivEnergy inverter remotely. In the event he was unsuccessful but he couldn’t have been more helpful. If you have problems with a GivEnergy system please contact him. Highly recommended
Big thanks to Ron. He was incredibly patient and helpful over the phone, taking the time to walk myself and the installer through every troubleshooting step. Through lots of testing he figured out the issue was definitely a hardware issue, which allows us to consider our next steps. Support fees are clear and they operate a “no fix no fee” policy. It is rare to find that kind of honesty combined with dedicated phone support nowadays. I highly recommend Ron, if you need help with your solar system don’t hesitate to give him a call.
A superb service from Ron who went beyond the normal service received from other Tech support companies. I live abroad and was badly let down when my givenergy system failed (and the company went bankrupt) and the local supplier ran away from the problem. Ron sorted the problem and even accessed specialist coding for the inverter that would not be available for suppliers. Ron also ran a full diagnostic to insure that all was in good working order afterwards. Without Rons support and patient assistance I doubt I would ever have got the system back up and running. Well done and thankyou and you have a customer for the future.

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.
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.
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.
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.
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%).
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.

WiFi connected but portal still shows no data — all causes and fixes.
All GivEnergy setup guides — WiFi, monitoring, portal, firmware and more.
If you've followed the setup steps and the portal is still showing no data, the problem may be upstream — cloud-side, firmware, or a port block. Share what you're seeing and we'll identify the cause without a site visit.
I’ve worked on hundreds of GivEnergy systems and know the kit inside out. If yours is playing up, my promise is simple — no fix, no fee: just £75 if we fix it, free if we don’t.
