Contacted Solar Tech about my Givenergy battery storage system that wasn't working. Battery status was "idle". Given the company Givenergy had gone bust, I need independent quality technical help. Very patient and clearly very knowledgeable about battery systems Ron diagnosed possible issues and suggested several possible remedies. Worked our way through them and fortunately it began to work. The fault was very specific and only an experienced engineer would have thought to check. Suffice to say I'll be back if I need independent support again. Lastly you only pay if there is a solution. Outstanding.

Had a problem with my GivEnergy battery which had decided to charge and discharge to a very limited extent. From AI, felt that the problem was probably a calibration issue on the Battery Management System, but which I could not fix myself. So contacted Solar Tech Support, and Ron was brilliant in being able to identify, confirm and fix the issue remotely and very speedily. Thoroughly recommend this outfit
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.
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.
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.
Super support. Delighted I found them. System battery was down for quite a while and no one would try to fix it as GivEnergy out of business. A few hours later and I’m up and running again. Brilliant service!!! Highly recommend them.
Common Duracell Energy problems we diagnose
Every fault below has a proven diagnostic path. Click through for the specific page or book a diagnostic if you're unsure.
Battery stuck at low state of charge despite solar generation. Incorrect operating mode, battery communication fault, or grid protection blocking charge.
See diagnostic guide →Battery modules not communicating with inverter. Transient communication dropout from power cycle, firmware mismatch, or hardware fault.
See diagnostic guide →Duracell Energy app shows battery module error or isolation. Check app alarm log for specific code. Power cycle resolves most transient faults.
See diagnostic guide →App shows system as unreachable or no data. Communication module lost internet connection after router change or WiFi password update.
See diagnostic guide →Duracell Energy Home WiFi module not connecting or staying connected. Requires 2.4GHz — many issues from 5GHz-only routers. Start with our general WiFi checks. 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.
See general WiFi checks →Lost app access, account locked, or firmware update broke login. We restore access and verify settings configuration.
See diagnostic guide →Backup power not available during power cut. EPS disabled, wiring issue, or SoC below minimum threshold.
Guide →Duracell Home disconnecting from grid due to G98/G99 fault. Voltage, frequency, or isolation error.
See diagnostic guide →Duracell inverter not generating from panels. DC string fault, protection trip, or grid code lock.
Guide →Output lower than expected. Panel soiling, string fault, or firmware misconfiguration.
See diagnostic guide →Duracell Energy fault code index
Duracell Energy app logs fault codes and alarms when system errors occur. Our diagnostic process covers all fault categories and alarm codes across Duracell Energy Home models.

About Duracell Energy Home systems
Duracell Energy is a UK market brand offering an integrated home energy storage solution under the well-known Duracell brand. The Duracell Energy Home combines a hybrid solar inverter with modular battery storage in a single system managed through the Duracell Energy app. The system handles solar generation, battery charge/discharge, and grid connection — all displayed in the mobile app.
As a relatively new entrant to the UK market, firmware updates are common and can occasionally affect app connectivity and system behavior. EPS (Emergency Power Supply) is available but requires correct wiring to a dedicated backup circuit and must be enabled in system settings. Battery isolation alarms and communication faults are logged in the app alarm history.
