I work for a Solar Company and had a customer with a GivEnergy system that we are not versed in. Ron took the time to explain the issues my customer was having and between us managed to rectify the issues. 10 Stars ... Thanks again STS
Thank you for your diligence. On this occasion the battery was able to be saved but they have given a route to hopefully arrange a repair from the manufacturer.
I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.
Contacted Solar Tech Support in desperation. After explaining the issues I had with my system a diagnosis was made and a solution proposed. Fantastic service, even contacted a manufacturer to arrange replacement parts for me. Great communications, explained all they were doing and what I had to do, clearly and precisly. Followed up to confirm all was ok. Excellent service.
My GivEnergy hybrid inverter + battery system had worked faultlessly for 3 years when it suddenly stopped charging and discharging the battery. On contacting my supplier, who had used a sub-contractor for the installation work, I was provided with an email address at GivEnergy but, as it turned out, this is only for GivEnergy Software who are not able to assist. A Google search led to the Solar Tech Support web site, which contains a wealth of helpful information. I requested a remote solar diagnostic, and after providing Ron access to my inverter, he was able to identify and fix the problem within minutes. I am very impressed by Ron’s expertise and knowledge, which included useful information on the current state of GivEnergy Ltd. I would thoroughly recommend Solar Tech Support.
Ron was really helpful. He remotely adjusted my battery settings on the same day I contacted him, and at a reasonable price. Great service.
The GivEnergy dongle firmware update is done entirely through the dongle's local web interface — no internet access or portal login required. Have these four things ready before you start.
You need two separate files: the chipset firmware (T27 update file) and the bootloader version 1.1.4. Download both from the GivEnergy knowledge base before starting. The chipset file must always be applied first — uploading the bootloader before the chipset will cause the update to fail.
You'll connect directly to the dongle's WiFi hotspot to access its local interface. Note the dongle SSID and password from the label before you start — the SSID typically starts with GIV_ followed by the serial number. If the label password doesn't work, try the serial number itself.
The dongle PCB has DIP switches that must be set before uploading firmware. DIP switches 2 and 3 must be OFF before you upload either file. If you cannot see them clearly, use a torch. This is the single most common cause of failed updates — do not skip it.
After the firmware update completes, you'll re-enter your home WiFi credentials in the dongle interface. The dongle only supports 2.4 GHz networks. If your router broadcasts a combined 2.4/5 GHz SSID, the dongle may need a dedicated 2.4 GHz SSID to connect reliably.
Follow these steps in exact order. DIP switches must be set before any upload, and the chipset file must be applied before the bootloader. There is no shortcut here — the sequence matters.
On your phone or laptop, open WiFi settings and connect to the dongle hotspot SSID (starts with GIV_, printed on the dongle label). Use the label password. Once connected, your device will show no internet access — this is expected.
Open a browser and go to http://10.10.100.254. Use plain HTTP — not HTTPS. Log in with username admin and password admin. If these credentials don't work, try the dongle serial number as the password.
Locate the DIP switches on the dongle PCB. Set DIP switch 2 and DIP switch 3 to the OFF position before uploading any firmware. This puts the dongle into update mode.
In the dongle interface, navigate to the firmware update section. Select and upload the chipset firmware file (T27 update). Click Upload and do not close the browser or disconnect from the hotspot during upload. The dongle will automatically reboot when complete.
Reconnect to the dongle hotspot after the reboot before proceeding to step 5.
After the chipset update and reboot, reconnect to the dongle hotspot, navigate back to http://10.10.100.254, and log in again. Upload the bootloader firmware file version 1.1.4.
Once the bootloader update completes and the dongle has rebooted, return DIP switches 2 and 3 to the ON position. If left in the OFF (update) position, the dongle will not connect to your home WiFi network.
After a firmware update, stored WiFi credentials may be cleared. Follow these steps to reconnect and verify the portal is reporting correctly.
Connect to the dongle hotspot, log into http://10.10.100.254 with admin/admin, and navigate to the WiFi or STA (Station) settings page. This is where you configure the dongle's connection to your home router.
The dongle only supports 2.4 GHz networks. If your router broadcasts a combined band SSID, use your router admin panel to create a dedicated 2.4 GHz SSID, or check that band-steering will correctly associate the dongle to 2.4 GHz. Enter the correct SSID and password and save.
In the dongle interface, check the RSSI (signal strength) after connecting. GivEnergy recommends 70% or above for reliable operation. Below 70% you'll see intermittent portal dropouts and monitoring gaps. If signal is weak, use a WiFi extender or powerline adapter near the inverter.
Allow 5–10 minutes after reconnecting, then log into givenergy.cloud and confirm the inverter shows as online with live data updating. If the inverter remains offline after 15 minutes, remove the dongle from the inverter, wait 30 seconds, and reinsert it.
If the firmware update fails or the dongle won't connect after updating, work through these checks before calling for support.
If the local interface doesn't load, confirm your device is still connected to the dongle hotspot — not your home network. On many phones, if no internet is detected on a connected network, the device automatically switches back to a network with connectivity. Disable mobile data, check WiFi settings, and confirm you're on the dongle SSID.
If the dongle hotspot is not visible at all, hold the reset button for 10 seconds to factory reset the dongle. This will restore hotspot mode and the default admin/admin credentials.
Failed uploads are almost always caused by DIP switches not being in the correct position. Power off the dongle, set switches 2 and 3 to OFF, power back on, reconnect to the hotspot, and retry the upload from step 4. Do not try to reorder the files — chipset must always come before bootloader.
Also confirm you have the correct firmware files for your exact dongle hardware version. The GivEnergy knowledge base lists the correct file pairing for each dongle variant. Using a file from the wrong variant will cause the upload to fail.
The GivEnergy dongle communicates with the cloud on port 7654. Some routers or parental control systems block outbound connections on non-standard ports. Check your router's firewall settings and ensure outbound traffic on port 7654 is not being blocked.
Also check the dongle has a valid DHCP-assigned IP address from your router (not 10.10.100.254, which is the hotspot address). If it shows 10.10.100.254 after connecting, the router hasn't assigned an IP — try rebooting your router and the dongle.
Intermittent dropouts after an update almost always indicate a WiFi signal problem. Check the RSSI in the dongle interface — below 70% the connection is marginal. Try moving a WiFi extender closer to the inverter, or use a powerline adapter for a wired-equivalent connection to the router.
Also confirm the dongle is connecting to 2.4 GHz. If your router uses the same SSID for both bands, check your router's client list or the dongle's interface to confirm which radio it has associated with. 5 GHz has shorter range through walls and is not supported.
If the firmware update has left the dongle unable to boot or enter hotspot mode, if you're not comfortable with the DIP switch process, or if the portal has been offline for more than 24 hours despite working through this guide — get in touch.
