I received a prompt response and excellent technical support for the remote diagnosis (Oxfordshire) and resolution of my GivEnergy EMS configuration. My GivEnergy issue involved a single inverter and battery that had a loss of calibration, a critical low voltage drop. It needed a recovery and re-calibration, and was supported via email into yesterday evening being resolved within 24 hours. Ron demonstrated a very high level of knowledge and experience in the intricacies of a GivEnergy EMS configuration, even surpassing the understanding of GivEnergy itself when it was still operational. I have already recommended their services to a neighbour as I’d be happy to use their services again based on the fair pricing and the quality of their support.

In the event he was unsuccessful but he couldn’t have been more helpful. If you have problems with a GivEnergy system please contact him. Highly recommended
Wow!!! I have a Givenergy system. The battery stopped charging and depleted fully. Obviously Givenergy went into administration, so I was working with the reseller / installer to get it fixed. They told me they couldn't resolve it and the best they could do was offer me a replAcement at cost, so basically having to buy a new system. I happened to come across STS when searching for how to fix it myself. Ronald has been a god send, within 2 days all is working perfectly and set up correctly. When it comes to experts. He truly is the expert. If you have issues with your Givenergy system and don't know where to go for good help, give him call. 07944 877329. Thanks Ronald, regards Neil W
Absolute legend found the fault in 5mins definitely will be using again definitely would recommend to others .
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!
Absolutely fantastic experience, after months of being fobbed off with rubbish from the installer Ronald fixed my issues in a few hours, his attention to detail and his tenacity was amazing, not only did he go above and beyond but did not ask for payment i had to ask him how to pay. If you need a solar fix this company is brilliant
Three waves of battery installation — and why EPS was often missed
Nottingham's battery installations arrived in distinct waves, each with different hardware and different reasons why EPS was left out.
First-generation GivEnergy and Growatt batteries added to FiT-era systems. EPS was rarely offered as a standard option at this point — many installers were still learning the products. These systems are now five to seven years old and most support EPS with a simple wiring addition.
High electricity prices drove a surge of battery installs across Nottingham's suburban belt — Arnold, Carlton, Mapperley, West Bridgford. Installers were stretched thin and EPS wiring was often skipped to save time or reduce the quote. These systems are fully EPS-capable but need the circuit added.
Modern estates around Beeston, Gamston, and Colwick Park come with hybrid inverters and batteries as standard. Some include EPS pre-wired; others do not. If your new-build has a hybrid inverter but no dedicated EPS circuit, the wiring addition is usually straightforward.
Regardless of which wave your battery came from, the EPS installation process is the same: we wire the inverter's EPS output to the circuits you want protected, check the island-mode earthing, configure the inverter, and load-test on site. Full guide to the 4 EPS configuration types →
EPS for landlords and managed properties
Nottingham's large student and rental market means a significant number of battery-equipped properties are landlord-owned. EPS adds practical value to these properties beyond daily bill savings — and creates documentation that protects both landlord and tenant.
A dedicated EPS circuit keeps heating, hot water, broadband, and lighting running during power cuts. For rental properties in Beeston, Lenton, and Dunkirk — where tenants pay their own electricity — this is a tangible feature in a listing. It also reduces the chance of emergency call-outs to the landlord during outages.
We provide a written post-installation report including EPS circuit identification, protected circuits listed, and inverter configuration record. For landlords managing multiple properties or working through letting agents, this documentation sits alongside the EPC and electrical certificates.
If your rental property has battery storage but no EPS, adding a dedicated circuit is one of the most cost-effective upgrades you can make — the battery hardware is already there. Battery retrofit for Nottingham properties →
Battery installed by a company that no longer exists?
Nottingham has been heavily affected by installer collapses — Mark Group (2015), Solarplicity (2023), and smaller local firms. Some of these companies installed battery systems; others installed solar-only and a third party added the battery later. In either case, if the original installer is gone and your battery was left without EPS wiring, we can pick up from where they left off. We work on GivEnergy, Growatt, Fox ESS, Sunsynk and SolaX systems.
If your system is solar-only with no battery yet, you'd need a battery retrofit first — we can combine that with EPS wiring in a single project.
EPS enabled but nothing happens during a power cut?
A recurring pattern across Nottingham: the battery app shows EPS mode is enabled, the battery is fully charged, but when the grid drops — either the lights go off like normal, or the protected circuits trip. Common causes are a wiring fault on the EPS circuit, a missing or doubled neutral-earth reference, or a setting. GivEnergy's hybrids make their own reference, so an extra permanent bond on the EPS output doubles it and can itself cause trips. We find the cause with island-mode tests, put it right, run a grid-failure simulation and confirm everything works under load, usually in one visit.
GivEnergy is the most common battery brand across Nottingham — and the one we see this fault on most often.
