Solar Tech Support is an absolute lifesaver. My solar and battery system stopped working completely, but after one quick phone call, they fixed the problem straight away. The original provider, GivEnergy, has gone into administration, leaving me entirely without support from the original installers. It was a terrible situation on GivEnergy’s part, but thankfully, Solar Tech Support came to the rescue!

When my GivEnergy battery started playing up it became basically useless and several companies I called said they couldn’t help. Solar Tech Support really knew their stuff, communicated very well and resolved the problem quickly. Without them I’d have had to buy a replacement battery.

I’ve used Ron a couple of times regarding issues with my Givenergy inverter and batteries after Givenergy went bust. My system stopped working properly so it was a stressful time but Ron resolved the issues and got my system working properly again. He’s really helpful and knowledgeable and I wouldn’t hesitate to recommend him and to use him again if the need arose.

Overview
What is the GivEnergy AECC dongle?
The AECC (Advanced Energy Communication Controller) is GivEnergy's newer communication module, replacing the original WiFi dongle on Gen 4 inverters and fitted to some AIO 2 and Gateway 2 units. It has a different interface, different default credentials, and does not use DIP switches.
1
Different interface address and protocol
Unlike the older WiFi dongle (which uses http://10.10.100.254), the AECC dongle uses https://10.10.100.254/web/info — note the HTTPS and the /web/info path. Navigating to plain HTTP or the root address will not load the interface correctly.
2
Different default password
The AECC dongle's default login is username admin, password 123456. The older WiFi dongle uses admin/admin. Using the wrong credentials is the most common reason people can't access the AECC interface after first trying the older dongle's details.
3
No DIP switches required
The AECC dongle does not have DIP switches. All configuration is done through the web interface. Firmware updates for the AECC are handled differently — check the GivEnergy knowledge base for AECC-specific firmware guidance.
4
Fitted to newer GivEnergy inverter models
The AECC is standard on Gen 4 inverters and is also found on some AIO 2 and Gateway 2 units. If you're not sure which dongle you have, check the model label on the dongle itself — AECC units will show the AECC designation.
Configuration
Connectivity options and priority
The AECC dongle supports multiple connectivity methods with a defined priority hierarchy. The dongle automatically uses the highest-priority connection available.
1.
LAN (Ethernet)
Primary method when a cable is physically plugged in. Provides the most reliable and fastest connection to your home network and the GivEnergy portal.
→ Use for permanent installations
2.
WiFi (2.4 GHz)
Secondary fallback when LAN is not available. Requires 2.4 GHz network (5 GHz not supported). Configured in STA Settings within the AECC interface.
→ Main backup method
3.
4G Cellular
Emergency backup for remote diagnostics and troubleshooting. Not intended for routine operation. Requires SIM card and available signal at the installation site.
→ Remote diagnostics only
4.
Bluetooth
Installer app commissioning only. Used during initial setup and configuration by GivEnergy engineers and certified installers. Not used for ongoing operation.
→ Setup and commissioning
Step 1
Interface access
Accessing the AECC local interface
The AECC dongle has a local web interface accessible via its WiFi hotspot. Here's how to reach it.
1
Connect to the AECC hotspot
On your phone or laptop, connect to the AECC dongle's WiFi hotspot. The SSID is printed on the dongle label. Once connected, your device will show no internet access — this is expected while connected to the dongle hotspot.
2
Navigate to https://10.10.100.254/web/info
Open a browser and go to https://10.10.100.254/web/info. You may see a browser security warning about the certificate — this is expected for a local device and safe to proceed past. Click "Advanced" and then "Proceed" (or equivalent in your browser).
3
Log in with admin / 123456
Enter username admin and password 123456. These are the factory default credentials for the AECC dongle. If these don't work, the password may have been changed by a previous engineer — a factory reset will restore the defaults.
Quick reference:
URL: https://10.10.100.254/web/info
Username: admin
Password: 123456
Username: admin
Password: 123456
Step 2
WiFi configuration
Configuring STA and AP settings
The AECC has two separate WiFi configuration sections: STA (Station) for connecting to your home router, and AP (Access Point) for the dongle's own hotspot. Both can operate simultaneously.
STA Settings — connecting to your home WiFi
In the AECC interface, navigate to STA Settings (Station mode). This section controls how the dongle connects to your home WiFi router.
1
Enter your home WiFi SSID (network name) and password exactly. The SSID and password are case-sensitive.
2
Confirm the network is 2.4 GHz. The AECC dongle does not support 5 GHz networks. If your router broadcasts a combined SSID, use a dedicated 2.4 GHz SSID for reliable operation.
3
Click Save and wait for the dongle to connect. The status indicator will change once a successful connection is established. Allow up to 2 minutes.
AP Settings — configuring the dongle hotspot
Navigate to AP Settings to configure the dongle's own WiFi hotspot. You may need to change the AP settings if you want a custom hotspot name or password, or after a factory reset if you need to restore access.
The hotspot SSID and password are separate from the home WiFi credentials. Changing the AP settings does not affect the STA (home WiFi) connection.
Note: If you change the AP password, you will need to reconnect your phone to the dongle hotspot using the new password before you can access the interface again.
Verifying portal connectivity
After saving STA settings, allow 5–10 minutes and then log into givenergy.cloud. The inverter should show as online with live data updating. If it remains offline:
1
Check the SSID and password are correct and the network is 2.4 GHz.
2
Check the RSSI signal strength in the AECC interface — aim for 70% or above.
3
Check your router isn't blocking outbound connections on port 7654.
Factory reset
Reset button
AECC reset button — location by inverter model
The reset button location on the AECC dongle varies depending on which GivEnergy inverter model it is fitted to. Hold the button for 10 seconds to perform a factory reset — this clears WiFi credentials and restores default login details.
Gateway 2
The reset button on the AECC dongle fitted to the Gateway 2 is located at the top centre of the dongle PCB.
Hold for 10 seconds until the LED flashes to confirm reset.
AIO 2
On the AIO 2 (All-in-One 2), the AECC reset button is at the top right near the DC connections on the dongle.
Check the DC connection area at the top right of the dongle for the small recessed button.
Gen 4
On the Gen 4 inverter, the AECC reset button is at the bottom centre of the dongle module.
Look at the bottom of the dongle — the reset button may require a pin or paperclip to press.
After a factory reset: Hold the reset button for 10 seconds until the LED flashes. The dongle will return to default credentials (admin / 123456) and will broadcast its default hotspot SSID. Reconnect to the hotspot, navigate to https://10.10.100.254/web/info, log in, and re-enter your home WiFi credentials in STA Settings.
Troubleshooting
Common issues
AECC dongle problems and fixes
The AECC is generally more reliable than the older dongle, but these issues do come up in the field.
Can't access https://10.10.100.254/web/info
If the page won't load, confirm you are connected to the AECC hotspot and not your home WiFi. Many phones switch away from networks with no internet connectivity automatically — disable mobile data and check WiFi settings. Also confirm you are using HTTPS and including the /web/info path in the URL.
If your browser shows a security warning about the certificate, click "Advanced" and proceed — the certificate warning is expected for a local device interface.
Wrong password — admin/admin doesn't work on the AECC
The AECC dongle uses admin / 123456 as its factory default — not admin/admin like the older WiFi dongle. If neither works, the password has been changed. Factory reset the dongle (10-second button hold) to restore the default credentials.
AECC connected to WiFi but GivEnergy portal shows offline
If the AECC shows as connected in STA Settings but the portal remains offline, check that outbound traffic on port 7654 is not being blocked by your router. Also confirm the RSSI is 70% or above — a weak signal can cause the portal connection to drop even when the WiFi association appears connected.
Try power-cycling the dongle: remove it from the inverter, wait 30 seconds, and reinsert. If the inverter has gone into a fault state, check the hardware diagnostics guide before continuing.
AECC keeps losing WiFi connection intermittently
Intermittent drops are almost always a signal strength issue. Check the RSSI in the AECC interface — below 70% is marginal. The inverter is typically in a utility cupboard or garage where walls and interference reduce signal. A WiFi extender positioned nearby or a powerline adapter with a WiFi point at the inverter location will provide stable connectivity.
Also confirm the AECC is connecting to 2.4 GHz — 5 GHz has shorter range and is not supported by the dongle hardware.
When to get professional help with your AECC
If the AECC hotspot isn't visible and a factory reset hasn't restored it, if the portal has been offline for more than 24 hours despite correct WiFi credentials, or if you're uncertain about the configuration on a newly installed Gen 4 or AIO 2 — we can diagnose and configure AECC dongles remotely in most cases.

GivEnergy AECC dongle questions
The GivEnergy AECC dongle's local interface is at https://10.10.100.254/web/info. This is different from the older WiFi dongle (http://10.10.100.254). You must be connected to the AECC's WiFi hotspot to access this address. Your browser may show a certificate warning — this is normal and safe to proceed past by clicking "Advanced" then "Proceed".
The factory default login for the GivEnergy AECC dongle is username admin, password 123456. This is different from the older WiFi dongle which uses admin/admin. If these credentials don't work, the password has been changed — perform a factory reset (hold reset button 15 seconds) to restore the defaults.
The reset button location varies by inverter model. On the Gateway 2, it is at the top centre of the dongle. On the AIO 2, it is at the top right near the DC connections. On the Gen 4, it is at the bottom centre. Hold the button for 10 seconds to factory reset — this clears WiFi credentials and restores admin/123456 as the login.
STA Settings (Station mode) controls how the AECC dongle connects to your home WiFi router — this is where you enter your home SSID and password. AP Settings (Access Point mode) controls the dongle's own WiFi hotspot, including its SSID and password. Both can run simultaneously — the dongle connects to your router (STA) while also broadcasting its own hotspot (AP) for local access.
No. The AECC dongle does not use DIP switches for standard WiFi configuration. DIP switches are a feature of the older WiFi dongle and are only needed for that dongle's firmware update process. All AECC configuration is done through the web interface at https://10.10.100.254/web/info.
The remote diagnostic is free — if we can't get your dongle reporting to the portal, there's nothing to pay. AECC setup and connectivity problems (WiFi/STA settings, router ports, a stuck session) are sorted remotely for a flat £75, and only if it works. If the dongle hardware has actually failed and needs replacing, that's a small part quoted up front. No fix, no fee. Full pricing →
Usually the same day. A 30-minute remote session walks through the STA/AP settings, the router 2.4GHz band and outbound ports, and the local interface, and the inverter normally reappears in the portal within 5–10 minutes of a successful connection.
