Great service. Got our Givenergy battery back online remotely when others said it needed an onsite visit. Ron resolved the issue within about an hour of my email. Brilliant service.

My Givenergy system went offline, so I lost control of it. Ron from STS and Craig from Norfolk Solar were most helpful in diagnosing the problem by phone. Full marks for their patience and ability.

Absolutely amazing service. Ive had a couple of issues with my Givenergy system and couldn't manage to get in touch with Givenergy after they went bust. So I was searching on Google and came across Rons number. I sent Ron a WhatsApp message and got a prompt reply and he resolved the problem I had with my system. I can't recommend Ron enough its not often you get such a good service in this day and age. If you are experiencing issues with your solar system Ron is the man to contact.

My 90-year-old father-in-law had a solar system installed nearly three years ago that never worked properly and kept tripping out. Neither the original installer nor GivEnergy could resolve the issues, and we were even pushed towards replacing the system entirely when GivEnergy went bust. I contacted Ron at Solar Tech Support via WhatsApp, and within a few hours he had diagnosed multiple faults — including incorrect wiring that posed a potential fire risk. He carried out a home visit in Nottingham for £295 (including parts), fixed everything, completed firmware updates, and ensured the system was fully operational. Since then, it has worked perfectly. Ron was knowledgeable, responsive, and took the time to explain everything clearly. Highly recommended — excellent value and complete peace of mind.

Overview
What is the GivEnergy AECC dongle?
GivEnergy calls it the AECC multi-connect dongle. It links an All-in-One 2 (AIO 2) or Gateway 2 to your home network and to GivEnergy's servers. You set it up through its own web page, and it works differently from the older plug-in dongle.
1
Used on the AIO 2 and Gateway 2
GivEnergy's AECC setup guide covers these two units. GivEnergy also lists a WiFi 6 dongle for the AIO 2 and Gateway 2, which is set up differently. The steps on this page are for the AECC only.
2
A different address and login
The AECC's page is at https://10.10.100.254/web/info. The default login is admin / 123456, and it makes you set a new password at first login. The older plug-in dongle uses http://10.10.100.254 and admin / admin. The older dongle's details will not work on an AECC.
3
Several ways to connect
A network cable (LAN), WiFi, and 4G as a backup, plus Bluetooth for the installer app. See which connection it uses.
4
Ask us before any firmware update
The dongle has a Software Upgrade page. GivEnergy's guide says to update only when GivEnergy tells you to, because the factory versions are fully tested. We don't advise self-service firmware updates through the dongle, the portal or the app. If you think it needs one, talk to us first: we can do it on a callout.
Connections
Which connection the AECC uses
The dongle works down a fixed order and uses the first connection that is available.
1.
LAN (network cable)
Used first whenever a cable from your router is plugged in. The System page then shows an IP address from your router. The best choice wherever a cable can be run.
→ Best for a permanent setup
2.
WiFi
Used when no cable is connected. You set it up in STA Settings (step 2 below), with WPA2-PSK or, on some modern routers, WPA3.
→ The usual home setup
3.
4G
A backup for remote diagnostics. GivEnergy's guide says it should not be used for routine operation.
→ Backup only
Bluetooth and the hotspot: Bluetooth is on by default and is used by the installer app when the system is commissioned. The dongle's own hotspot has no password out of the box, so secure it in AP Setting (step 4) whichever connection you use.
Step 1
Log in
Join the hotspot and log in
Do this standing near the AIO 2 or Gateway 2, with it powered on. Have your home WiFi name and password ready.
1
Join the dongle's own WiFi
On your phone or laptop, join the network named like WN2535G070. It has no password on first use. If it asks for one, reset the dongle: hold its reset button for 10 seconds.
2
Ignore the "no internet" warning
Your device may say that no internet is available. That is normal: stay connected. If your phone keeps jumping off the hotspot, turn mobile data off and stop it rejoining your home WiFi until you have finished.
3
Go to https://10.10.100.254/web/info
Type the full address, with https and /web/info. Your browser may show a security warning: accept it to reach the login page.
4
Log in and set a new password
Username admin, password 123456. You are then asked for a new password, which must include letters and numbers. Write it down. Take care not to type the new password into both the username and password boxes.
5
Read the System page
You start on the System page. It shows the WiFi, LAN and 4G status and the dongle's software version. If a cable is plugged in, LAN shows an IP address from your router. If WiFi is not set up yet, that section shows no network name or signal.
Quick reference:
URL: https://10.10.100.254/web/info
Username: admin
Password: 123456 (you set a new one at first login)
Username: admin
Password: 123456 (you set a new one at first login)
Steps 2 to 5
WiFi and hotspot
Connect it to your WiFi, then secure it
STA Settings connect the dongle to your home WiFi. AP Setting controls the dongle's own hotspot. Do both, in this order.
Step 2. STA Settings: join your home WiFi
Select STA Settings from the menu.
1
Press Choose and select your home WiFi network.
2
Enter the WiFi password exactly. It is case-sensitive, and symbols must match.
3
Set Authentication Mode to WPA2-PSK, the most common, or WPA3 on some modern routers.
4
Leave every other setting as it is and press Save.
Step 3. Check the System page
Go back to System. If the STA section is empty, press Refresh.
1
Your network name, a signal strength and an IP address: it is connected.
2
Your network name but no IP address or signal: the WiFi password is wrong. Go back to STA Settings and enter it again.
Step 4. AP Setting: secure the dongle's hotspot
The hotspot is not secured by default, and GivEnergy's guide says you must secure it. Select AP Setting and set:
1
AuthMode: WPA2-PSK (or WPA3 if you prefer).
2
Password: a secure password. Write it down.
3
Channel: Auto. SSID Hidden is optional. Change nothing else, then save.
Note: once the hotspot has a password, you need it to join the hotspot next time. Keep it with the login password.
Step 5. Check it is online
GivEnergy's guide says the unit should appear online in the GivEnergy portal within a few minutes of connecting by LAN or WiFi. Check the web portal at givenergy.cloud, or the app signed in to your account away from your home network. Both need GivEnergy Premium. Readings in the app's local mode do not prove the cloud link: local mode reaches the unit over your home network, not through the cloud. The app and portal are run by GivEnergy Software Ltd, which is still trading. It is a separate company from GivEnergy Ltd. If it stays offline:
1
Check the System page shows an IP address. If not, enter the WiFi password again.
2
Check the signal strength on the System page. We work to 70% or better on GivEnergy dongles.
3
Check your router or firewall is not blocking outbound TCP port 7654. See port 7654 blocked.
Factory reset
Reset button
AECC reset button on the AIO 2 and Gateway 2
Hold the reset button for 10 seconds to factory reset the dongle. Do this if its hotspot asks for a password nobody knows, or if nobody knows the login password.
Gateway 2
GivEnergy's guide puts the reset button at the top centre of the unit.
Hold it for 10 seconds, then look for the dongle's hotspot again.
AIO 2
On the All-in-One 2, GivEnergy's guide puts it at the top right of the DC isolation area.
Hold it for 10 seconds. Never take a cover off to reach it.
After a factory reset: the dongle goes back to its factory settings and drops off your WiFi. Start again from step 1: join the open hotspot, log in as in step 2, set a new password, then redo STA Settings and AP Setting. GivEnergy's guide is written for installers. If you can't reach the button without removing a cover, stop and book on-site WiFi setup.
Troubleshooting
Common issues
AECC dongle problems and fixes
Common problems during setup, and what to check for each.
Can't open https://10.10.100.254/web/info
Check you are still on the dongle's hotspot, not your home WiFi. Phones often leave a network that has no internet, so turn mobile data off and try again. Type the address in full, with https and /web/info, and accept any browser security warning.
If it still won't load while you are on the hotspot, your unit may have GivEnergy's WiFi 6 dongle instead, which is set up differently, and we can set it up on site, from £195.
admin / 123456 is refused
The dongle makes you set a new password at first login, so someone may already have changed it. admin / admin is the older plug-in dongle's login and won't work here. If nobody knows the new password, a factory reset returns the dongle to its factory settings, so you can set it up again from step 1.
Network name shows, but no IP address or signal
The WiFi password is wrong. Enter it again in STA Settings: it is case-sensitive, symbols must match, and a stray space at the end will stop it. Check the Authentication Mode matches your router: WPA2-PSK on most, WPA3 on some modern routers.
Connected, but not showing online
If the System page shows an IP address but the unit isn't online after a few minutes, check that outbound TCP port 7654 is not blocked by your router or a firewall. A GivEnergy cloud outage looks the same from your side. Our app or portal offline guide covers every cause.
Drops off the WiFi now and then
This is usually the signal. Check the signal strength on the System page: we work to 70% or better. On the Gateway 2, check the WiFi antenna supplied with it is fitted. A network cable to the LAN port is the most reliable fix, because the dongle uses LAN first. A WiFi extender near the unit is the other option. If the signal still won't reach, we can fit a WiFi extender on site: our WiFi setup visit is from £195, and the extender is an extra £75.
When to get help with your AECC
If the hotspot doesn't appear even after a factory reset, if you can't reach the reset button without removing a cover, or if the unit still isn't online a day after the System page showed an IP address, we can set it up on site, from £195. We don't set up or diagnose WiFi remotely or over the phone: it's quicker and more reliable done on site.

Its setup page is at https://10.10.100.254/web/info. Note the https and the /web/info on the end. Connect to the dongle's own WiFi hotspot first. Your browser may show a security warning: accept it to reach the login page. The older plug-in dongle uses http://10.10.100.254 instead.
Username admin, password 123456. At first login it makes you set a new password, which must include letters and numbers. If admin / 123456 is refused, someone has already changed it. If nobody knows the new one, a factory reset (hold the reset button for 10 seconds) returns the dongle to its factory settings. The older plug-in dongle uses admin / admin.
The All-in-One 2 (AIO 2) and the Gateway 2. GivEnergy also lists a WiFi 6 dongle for these two units, which is set up differently. If https://10.10.100.254/web/info will not load while you are connected to the hotspot, your unit may have the other dongle, and we can set it up on site, from £195.
GivEnergy's guide puts it at the top centre of the unit on the Gateway 2, and at the top right of the DC isolation area on the AIO 2. Hold it for 10 seconds to factory reset. The dongle then needs setting up again from the start, including a new login password and your WiFi details.
STA Settings connect the dongle to your home WiFi: you choose your network, enter its password and pick WPA2-PSK or WPA3. AP Setting controls the dongle's own hotspot, the one you join to set it up. The hotspot has no password out of the box, so set AuthMode to WPA2-PSK and give it a secure password.
No. It uses a network cable (LAN) first whenever one is plugged in, then WiFi, then 4G. GivEnergy's guide says 4G is a backup for remote diagnostics only, not for routine use. Secure the dongle's own hotspot in AP Setting whichever connection you use: GivEnergy's guide says it is not secured by default and you must secure it.
Not on your own. GivEnergy's guide says to update it only when GivEnergy tells you to, because the factory versions are fully tested. We don't advise self-service firmware updates through the dongle, the portal or the app. If you think it needs one, talk to us first: we can do it on a callout.
Follow the free step-by-step guide on this page. If it still won't connect, we set it up on site, from £195: we connect it to your WiFi, set up your router, including a separate 2.4 GHz network if it needs one, and check it's reporting. If the signal doesn't reach, a WiFi extender is an extra £75, and we carry them with us. If the dongle hardware has failed, we tell you what it needs and quote before any further work.
If you follow the steps on this page, GivEnergy's guide says the unit should show online within a few minutes of connecting. We don't set up or diagnose WiFi remotely or over the phone: it's quicker and more reliable done on site. If it still won't connect, we can set it up on site, from £195, and we tell you when an engineer can attend before anything is booked.
