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.

Excellent service from Solar Tech Support. Extremely quick to respond, easy to deal with and clearly very talented engineers. They were persistent throughout a complex GivEnergy battery issue and resolved everything completely. Highly knowledgeable, professional and reassuring support from start to finish. Highly recommended.
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.
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
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. 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.
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.
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.
See setup guide →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

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.
