Excellent knowledge and service. Ron responded to my initial query really quickly (same day), and confirmed that he could add extra panels and battery to my existing GivEnergy setup - something I’d been told by other installers wouldn’t be possible. Two weeks later (!), scaffolding was up and Ron and his team were on site to fit the extra 5 panels and two more GivEnergy batteries. I now have a truly optimised system, which has made the most of the south facing roof space I have, without having to start again with new kit. I’m now generating enough on the solar to fill my batteries, and avoid using the grid. I’ve also exported far more than before. Brilliant experience, well recommended.

I contacted STS when I was having problems with my GivEnergy AC3 inverter and they were extremely helpful. They took the time to properly investigate the system, talked me through a number of things we could try remotely, and ultimately inspected the system to establish what had gone wrong. They identified that the inverter’s battery board had failed beyond repair, while confirming that the two batteries themselves were still healthy. They also provided a clear report explaining their findings, which was particularly helpful given the current situation with GivEnergy. What impressed me most was their knowledge and willingness to help. They didn’t just give me a quick diagnosis — they took the time to understand the problem and explain the options available to me. I’m very pleased with the service I received from STS and would have no hesitation in recommending them to anyone needing help with a GivEnergy solar and battery system.

STS installed/commissioned an extra Givenergy battery for me. Communication was great and the engineer did a great job and even tidied up the existing wiring which made it look a great deal nicer than it did. Very happy so far and grateful to the team for their professionalism.

I had a red status light on my GivEnergy battery pack and Ron at Solar Tech Support was a great help resolving the problem. He was able to do a remote diagnosis of the invertor BMS firmware and hardware and gave very quick practical and professional support. Thanks Rob

Manchester context

Why so many Manchester batteries sit idle during power cuts

Eastern Greater Manchester saw heavy battery installation activity over the past three years — driven partly by government energy efficiency programmes and partly by high electricity prices pushing homeowners toward self-consumption. GivEnergy and Growatt are the dominant brands in this area. But a pattern we see repeatedly across Oldham, Tameside, and Stockport is batteries installed without EPS being wired up. The installer fitted the battery, configured it for daily charge/discharge, and left — without adding the circuit work that would let the battery power your home when the grid goes down.

Automatic

EPS takes over on its own when the grid fails

From £495

EPS wall socket installed, configured and tested

Half day

Typical installation time for a dedicated EPS circuit

The installation itself is usually straightforward — if your hybrid inverter supports EPS mode (and most do), we install the wiring from the inverter's EPS terminals to a new sub-board, check the island-mode earthing, configure the inverter, and load-test everything on site. Half a day's work in most cases. Full guide to the 4 EPS configuration types →

Terraced properties

EPS in terraced houses — working with compact consumer units

A high proportion of battery systems in eastern Manchester sit inside terraced houses — properties that were heavily targeted by ECO and Green Deal programmes. These homes typically have compact consumer units tucked under the stairs or in a small cupboard, often with no spare ways and limited mounting space.

Dedicated EPS sub-board

Rather than trying to squeeze additional breakers into a full consumer unit, we mount a separate EPS sub-board alongside it. This draws from the inverter's EPS output terminals and feeds whichever circuits you want protected — lights, fridge-freezer, boiler, broadband. Clean separation, no need to alter the existing board.

Neat routing in tight spaces

Under-stairs cupboards and narrow hallways are common in Oldham and Ashton-under-Lyne terraces. We use mini trunking and surface-mount routing to keep the EPS wiring tidy without needing to chase into plaster. The sub-board mounts directly beside the existing consumer unit — compact, accessible, and clearly labelled.

If your property had a battery installed through a government programme but the installer didn't wire up EPS, adding a dedicated circuit is often the most practical upgrade you can make. The battery hardware is already there — it just needs the wiring to use it as backup power. Adding a battery to your Manchester solar system →

EPS types

Four EPS configurations available in Manchester

Which option suits your property depends on what you want protected and how much of the house needs backup power. All four are available across our eastern Manchester coverage area.

Option 1
EPS wall socket

A single 13A socket wired directly from the inverter's EPS terminals. Enough for a router, phone charger, or lamp. The quickest option to install — often under two hours.

From £495
Option 2 — most requested
Dedicated EPS circuit

A separate sub-board protecting the circuits that matter — fridge-freezer, boiler, lights, broadband. Covers the essentials without the cost or complexity of switching the entire house. The most popular choice in Manchester terraces.

From £995
Option 3
Full-house manual changeover

A rotary isolator switch that lets you manually transfer your whole consumer unit to battery power. Full-house coverage — you just need to physically flip the switch when the grid drops.

From £1,495
Option 4
Full-house automatic changeover

An automatic transfer switch detects grid failure and switches your entire board to battery power. No manual intervention — the premium choice for properties where nobody may be home when the grid fails.

From £1,495

Pennine fringe

Power resilience on the Pennine edge

The eastern fringe of Greater Manchester — Stalybridge, Mossley, Glossop, Saddleworth, and the upper Tameside valleys — sits at higher elevations along the Pennine edge. These areas rely on overhead power lines that are more exposed to high winds, driven rain, and winter ice. Grid outages here tend to be more frequent and longer-lasting than in urban Manchester.

Overhead lines and weather exposure

Properties served by overhead distribution lines are the most vulnerable to storm-related outages. A 10 kWh battery with EPS provides 18–20 hours of backup at typical household loads — enough to cover most weather-related outages with margin to spare. For properties running oil or LPG heating, keeping the boiler circuit on EPS means you don't lose heating during extended winter outages.

Full-house changeover for rural-fringe properties

In Glossop, Saddleworth, and upper Mossley, where outages can run longer, a full-house automatic changeover switch is worth considering over a dedicated circuit. It protects the entire property without any manual intervention — particularly valuable if the house is unoccupied during the day or used as a holiday let.

If you already have battery storage at a Pennine fringe property but no EPS wiring, adding a dedicated circuit or changeover switch turns an existing investment into genuine power resilience. Full Manchester coverage details →

Compatibility

Inverter brands we configure for EPS in Manchester

EPS needs a hybrid inverter with battery storage. These are the main brands we work on across eastern Greater Manchester, and all support EPS mode when properly wired and configured.

GivEnergy

AIO and hybrid range. Was the most installed battery brand across eastern Manchester before the April 2026 administration; the installed hardware remains everywhere. EPS supported on all hybrid models — typically needs wiring and enabling through the GivEnergy portal or app. The Gen 1 All-in-One (6kW and 3.6kW models) has no EPS output: it backs up the whole house through a Giv-Gateway, or not at all.

Growatt

SPH and SPA series. Common on government-scheme battery retrofits in Oldham and Tameside. EPS configuration through System Parameters → Off-grid Settings on the inverter display.

Sunsynk

Hybrid range. Growing presence in newer Manchester installs. EPS via Advanced Settings → Off-Grid/EPS in the inverter menu. Reliable backup performance.

SolaX

Hybrid G4 range. EPS enabled via Settings → EPS Mode. Supports both dedicated circuit and full-house changeover configurations.

Fox ESS

H1, H3 and KH hybrids, AC-coupled AC1 and AC3, and EVO all-in-ones. EPS supported with appropriate wiring and island-mode earthing.

Others

Lux Power, Alpha ESS, Sigenergy, and more. If your hybrid inverter isn't listed, get in touch and we'll confirm whether it supports EPS.

Standard string inverters (SMA Sunny Boy, Fronius non-hybrid, SolarEdge single-phase) do not support EPS. If you have a string inverter and want backup power, you'd need an inverter replacement to a hybrid model first.

EPS not activating?

Battery has EPS enabled but trips or fails during outages?

It is a common EPS fault. The inverter has EPS mode turned on, the battery is charged, but when the grid actually fails, either nothing happens 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. Without a reference, RCDs cannot be relied on to disconnect an earth fault. GivEnergy's hybrids make their own, so an extra permanent bond on the EPS output doubles it and can itself cause trips. We find the cause with island-mode tests.

FAQ

EPS installation in Manchester — common questions

An EPS wall socket costs from £495 fitted. A dedicated EPS circuit protecting multiple rooms starts from £995 — that covers wiring, island-mode earthing checks, inverter configuration and load testing. A manual changeover switch for full-house backup costs from £1,495, and an automatic one from £1,495. Manchester pricing matches our standard rates with no additional travel charge for the eastern boroughs we cover.
Yes, provided the battery uses a hybrid inverter that supports EPS mode. Many government-funded battery installations across eastern Manchester were completed without EPS wiring — the scheme covered the battery and inverter but not the additional circuit work needed for backup power. If your hybrid inverter supports EPS (most GivEnergy, Sunsynk, and Growatt models do), we can add the dedicated circuit, check the island-mode earthing and configure it as a standalone job.
Yes. Terraced properties across Oldham, Rochdale, and Ashton-under-Lyne often have compact consumer units with limited spare ways. A dedicated EPS sub-board mounts alongside the existing board and draws from the inverter's EPS output — it does not need space inside the original consumer unit. We size the sub-board to the circuits you want protected and route the wiring to keep the installation neat in a tight cupboard or under-stairs space.
The Pennine fringe towns — Stalybridge, Mossley, Glossop, Saddleworth — sit at higher elevations with greater wind and storm exposure. Overhead power lines in these areas are more vulnerable to weather-related outages than underground urban supplies. If you already have battery storage, adding EPS means your system provides immediate backup when the grid drops — particularly valuable in locations where outages are more frequent and can last longer.
We schedule EPS installations across the eastern Greater Manchester boroughs within four weeks of booking, with no additional travel charge for the areas we cover. The work itself is quick once we arrive: a dedicated EPS circuit is half a day's work in most cases, and an EPS wall socket is often fitted in under two hours. If you are not sure whether your inverter supports EPS, a free compatibility assessment before booking will confirm it.
