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.
When my GivEnergy system had an issue, I was completely left without support and had honestly lost all hope. Thankfully, I searched online and found Ron, which completely turned things around. After sending him a message, he responded incredibly fast and called me to assure me that he would get the problem fixed. I really admire his dedicated, supportive nature and his determination to find a solution. With this kind of outstanding attitude and customer service, he has absolutely secured a future customer in me.
Ron want out of is way to help, nothing was to much. He was very thorough in what he did Very knowledgeable I would highly recommend Ron and his company He did a fantastic job for me. if you have any problems, he'll do his best to help you out and resolve your problem. I wouldn't hesitate to recommend them
Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)
Contacted Ron with a problem and he sorted it out quickly with no problems at all. Very knowledgeable on anything solar/ batteries. I would recommend him to anyone
I've spoken to Ron a couple of times with issues with my Givenergy installation. Such a friendly knowledge guy very highly recommended. Thank you very much for resolving my issues
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.
After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.
Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.
Ron is a super star. Two months ago my GivEnergy battery failed a firmware upgrade leaving it a brick. My installer couldn't/wouldn't fix it. GivEnergy couldn't/wouldn't fix it. Then they went into administration and all hope was lost. A flurry of emails later and Ron had diagnosed the fault (failed USB flash drive, something I'd suspected) and talked me through resolving it. Two months of nothing resolved in about 3 hours. It's great to work with someone who pays attention to the details, knows that they're doing (not just following a script) and gets stuff sorted without a fuss or up-charging.
I can add to the list of customers who had already 'given up' on GivEnergy due to their appalling customer service, and that was before they went into administration (their Trustpilot reviews don't lie!). So you can imagine my desperation when, having changed my ISP and my Inverter, predictably, proving to be the only device that didn't connect automatically to my new network, I found zero prospect of any customer support with GivEnergy having called in the administrators just five days earlier! The salvation came from Solar Tech Support. My IT advisor stumbled across their web site and some very helpful tips for beleaguered GivEnergy customers, as well as an offer to provide direct assistance. Nothing ventured, I decided to drop them an E-Mail, with very low expectations based on my experience of GivEnergy customer support. Within an hour Ron had responded with some pin point advice, and after a few exchanges of E-Mails he had nailed the problem, enabling the combined efforts of my IT advisor and solar installer to resolve it and reconnect my Inverter. Thank you Solar Tech Support, and Ron in particular, for coming to the aid of a deserted and despondent GivEnergy customer. Expert, razor sharp advice and first class customer service, even though I wasn't officially a customer.
This company are a rare gem, I had a very unusual problem following a failed firmware upgrade on my GivEnergy kit. I then found out GivEnergy were in administration and had dismissed all their support staff! None of the usual fixes to try and restore my inverter comms would work, and I looked everywhere, forums, GivEnergy youtube support videos - even AI couldn't figure it out. My installer was talking about huge sums for system replacements, and being vague / evasive about if they'd even install replacement GivEnergy inverter. Enter Solar Tech Support, reassuring and knowledgeable from the very start, I've learnt loads about my solar system though the friendly chat while my engineer worked as he diagnosed the problem and figured out a fix procedure that I've not found anywhere else - amazing . If you need solar system repairs - especially if you like me have been left high and dry by GivEnergy, I cannot recommend this company enough. Give them a call.
I sent a message on their website regarding a problem I have on my Givenergy system. Although not supplied by Ronald, I thought it was worth an email. Within the hour on a Saturday, he phoned and we discussed the problem. He logged in remotely and gave excellent advice. I'm too far away for his on-site help but he did diagnose the problem and was happy also to chat through my thoughts about an upcoming solar/battery install I'm planning. Great bloke.... if only he was nearer!

Why set up local monitoring?
GivEnergy systems support both cloud and local monitoring. The cloud portal at givenergy.cloud provides remote access from anywhere, but local monitoring gives you faster data, works during cloud outages, and opens up automation that the portal cannot do on its own.
The GivEnergy app's cloud connection refreshes every 5 minutes. In local mode it refreshes every 10–15 seconds. GivTCP and givenergy-local update even faster over Modbus. If you are diagnosing an intermittent fault or verifying that a charge command has taken effect, local data is far more useful than cloud data.
GivEnergy's cloud portal can be unavailable during maintenance or server issues. Local monitoring tools talk directly to the inverter on your home network — they continue working even when the portal is down. If you rely on monitoring for fault diagnosis or schedule management, local access provides a reliable fallback.
With GivTCP or givenergy-local and Home Assistant, you can automate charge and discharge schedules based on live Octopus Agile prices, weather forecasts, or household consumption patterns. This level of automation is not possible with the cloud portal alone and is one of the most powerful reasons to set up local monitoring.
Local monitoring via Modbus is a direct hardware protocol between your network and the inverter. It continues to work regardless of changes to cloud platforms, app updates, or server infrastructure. Your monitoring data stays on your own network.
GivEnergy app local connection — the easiest option
The GivEnergy app has a built-in local connection mode that talks directly to the inverter over your home WiFi. No additional software, no Home Assistant, no technical setup. This is the place to start for most homeowners.
How to enable local monitoring in the app
Open the GivEnergy app and tap the menu icon (three lines, top left).
Go to Settings → Local Monitoring.
Tap Scan for your inverter. Your phone must be on the same WiFi network as the GivEnergy dongle. Be patient — an IP address should appear below the scan option.
Once discovered, the app switches to Home mode. Data now refreshes every 10–15 seconds instead of the cloud's 5-minute interval.
Home mode vs Away mode
The GivEnergy app has two connection modes that determine how it communicates with the inverter:
Your phone talks directly to the inverter over your home WiFi. Data refreshes every 10–15 seconds. You must be on the same network as the dongle. Shows real-time solar generation, battery state of charge, grid import/export, and house consumption as it happens.
Data is routed through GivEnergy's cloud servers. Refreshes every 5 minutes. Works from anywhere with internet. Subject to cloud outages and server maintenance windows.
The app switches between Home and Away mode automatically based on whether it can reach the inverter locally. Both modes give you full access to schedules, system modes, and settings — the difference is data freshness.
Troubleshooting local connection
If the app cannot find the inverter locally or keeps falling back to Away mode:
Confirm your phone is on the same WiFi network as the dongle — not mobile data, not a guest network, and not a 5GHz-only connection if the dongle is on 2.4GHz.
Check that client isolation (sometimes called AP isolation) is disabled on your router. This setting blocks devices from talking to each other on the same network.
If you use a VPN app on your phone, it can route local traffic through the VPN tunnel and prevent the app from reaching the inverter. Disable the VPN or configure split tunnelling to exclude the GivEnergy app.
Try entering the dongle's IP address manually in Settings → Local Monitoring instead of relying on auto-discovery.
GivTCP — full local control with Home Assistant
GivTCP is the most capable local monitoring and control solution for GivEnergy systems. It communicates directly with the inverter via Modbus TCP on port 8899 and integrates with Home Assistant for data logging, dashboards, and full automation.
What GivTCP provides
All inverter registers exposed as Home Assistant entities — solar generation, battery state of charge, grid import and export, house load, inverter temperature, and more. Data updates every few seconds with no cloud lag.
Set charge and discharge schedules, system mode, and state-of-charge limits directly from Home Assistant. Automations can change settings based on time, tariff price, weather, or any other Home Assistant data source — without touching the cloud portal.
Combined with Home Assistant's Octopus Energy integration, GivTCP can automatically schedule charging during the cheapest Agile periods and discharge or export during the most expensive. This is one of the most popular reasons for setting up GivTCP.
Requirements and installation
A Home Assistant instance running on your network — Home Assistant OS on a Raspberry Pi, a Mini PC, or a Home Assistant Container installation.
The GivEnergy dongle connected to your home WiFi with a static IP address reserved on your router.
Install GivTCP via HACS (Home Assistant Community Store). The integration handles installation and configuration — enter the dongle's IP address and GivTCP connects over Modbus TCP on port 8899.
givenergy-local — a lighter Home Assistant integration
An alternative community integration for Home Assistant that also connects via Modbus TCP on port 8899. Developed by cdpuk, it focuses on monitoring and basic control with entities that plug directly into the Home Assistant energy dashboard.
Installation via HACS
Open HACS in Home Assistant and go to Integrations → Custom Repositories.
Add the repository URL: https://github.com/cdpuk/givenergy-local
Go to Configuration → Devices & Services → Add Integration, find GivEnergy Local in the list, and enter the dongle's IP address when prompted.
The integration exposes inverter and battery entities that work with the HA energy dashboard out of the box. It uses an embedded fork of the givenergy-modbus library, so there are no external dependencies to manage.
GivTCP vs givenergy-local — which to choose?
Both connect to the same Modbus TCP endpoint on port 8899. The main differences:
GivTCP is the more feature-rich option. Full schedule control, system mode switching, and deeper Octopus tariff automation. Better suited if you want to actively control the inverter from Home Assistant.
givenergy-local is lighter and more focused on monitoring. Good if you primarily want energy dashboard data and basic controls without the additional overhead.
You should only use one of these integrations at a time — do not run both simultaneously, as they would compete for the same Modbus TCP connection.
Direct Modbus TCP — for developers and custom systems
GivEnergy inverters expose a Modbus TCP server through the WiFi dongle. Any Modbus-compatible software can connect directly to read inverter registers without GivTCP, givenergy-local, or any intermediary.
Connection details
Port: 8899
Unit ID: 1
Port 8899 is supported by both the standard WiFi dongle and the newer AECC dongle. The register map is documented by the GivTCP project on GitHub. Read-only access to monitoring registers is available without authentication.
Compatible tools
Node-RED — visual automation flows with Modbus nodes for read and write operations.
PyModbus — Python library for custom scripts and energy management systems.
Grafana + InfluxDB — long-term data logging and custom dashboards from Modbus register data.
The dongle interface at 10.10.100.254 is for WiFi setup — not monitoring
There is a common misconception that the dongle's hotspot interface at 10.10.100.254 is a local monitoring tool. It is not. That interface is used exclusively during initial WiFi setup to connect the dongle to your home router.
What 10.10.100.254 actually does
When you hold the dongle's reset button (or on first power-up), it broadcasts its own WiFi hotspot. Connecting to that hotspot and navigating to 10.10.100.254 opens a basic setup page where you enter your home WiFi credentials. Once the dongle connects to your router, the hotspot closes and that interface is no longer accessible.
For local monitoring, use the GivEnergy app's local connection mode, GivTCP, givenergy-local, or direct Modbus TCP — all of which connect to the dongle's network IP address assigned by your router, not the hotspot IP.
If the app's local connection is not finding the inverter, GivTCP is not connecting, or you need help configuring automated tariff scheduling — we can diagnose and fix it in a remote session. We work with GivEnergy systems daily.
