Battery Retrofit Manchester

Already have solar panels? Adding a battery to your existing system is one of the most effective ways to increase your savings. Without a battery, most Manchester solar homes export 40-50% of their generated electricity to the grid at low export rates. A retrofit battery captures that surplus energy so you can use it in the evening and overnight, boosting self-consumption to 80% or more.

Manchester Renewables specialises in battery retrofits for all types of existing solar installations. Whether you have a string inverter, micro-inverters, or an older system, we will find a compatible battery solution. Our MCS-certified engineers assess your current setup, recommend the best retrofit approach (AC-coupled or DC-coupled), and complete the installation with minimal disruption — usually in a single day.

Battery Retrofit Manchester — What's Included

Existing System Assessment

We inspect your current solar panels, inverter model, wiring, and generation data to determine the best battery solution and coupling method.

Compatibility Analysis

Not all batteries work with all inverters. We check compatibility and recommend either AC-coupled batteries (work with any inverter) or DC-coupled options if your inverter supports them.

Retrofit Installation

Professional installation of your chosen battery, integrated with your existing solar system. Minimal changes to your current setup — we work with what you have.

Updated MCS Registration

Your MCS certificate is updated to reflect the battery addition, so you stay eligible for the Smart Export Guarantee.

Optimisation & Handover

We reconfigure your system for maximum self-consumption, set up battery scheduling, and walk you through the updated monitoring app.

Smart Export Guarantee: Earn more with smart export

With a battery, you can choose when to export surplus energy, timing it for the best SEG rates rather than exporting as you generate. Some suppliers offer time-of-export tariffs paying over 15p/kWh during peak periods. Your updated MCS registration keeps you eligible.

Why Battery Retrofit Manchester Matters

  • Retrofitting a battery can save an additional £400-£700 per year by capturing solar energy you currently export for just 4-15p/kWh
  • AC-coupled batteries work with virtually any existing solar inverter, making retrofits straightforward regardless of your current setup
  • Your existing solar panels continue working exactly as before — the battery simply captures the surplus they produce
  • A retrofit adds backup power capability to your solar system, protecting you during grid outages

Cost Guidance

Battery retrofit costs in Manchester range from £2,500 to £11,000 depending on battery size and coupling method. AC-coupled retrofits (the most common) typically cost £500-£1,000 more than new-build installations due to additional wiring and a separate battery inverter. A 5kWh retrofit costs approximately £3,000-£4,500, a 9.5kWh retrofit £5,000-£7,000, and a 13.5kWh retrofit £9,000-£11,000. All prices include 0% VAT.

Battery Retrofit Manchester — Common Questions

Can I add a battery to any existing solar system?
Yes, in most cases. AC-coupled batteries work with virtually any existing solar inverter. We check your system during the survey and advise on the best approach. Very old or non-standard inverters occasionally require additional components, which we identify upfront.
Do I need to replace my inverter to add a battery?
Not necessarily. AC-coupled batteries include their own inverter and connect alongside your existing setup. However, if your inverter is nearing end-of-life (typically 10-15 years), it may be worth upgrading to a hybrid inverter at the same time for a more integrated system.
How much extra will I save by adding a battery?
A typical Manchester household with a 4kW solar system saves an additional £400-£700 per year by adding a 10kWh battery. The exact figure depends on your energy usage patterns, existing self-consumption rate, and whether you also use a time-of-use tariff.
Will adding a battery affect my existing feed-in tariff?
If you are on the old Feed-in Tariff (FiT), adding a battery will not affect your generation tariff payments. You will still receive the same rate per kWh generated. However, you may export less energy (and receive fewer export payments) as the battery stores energy for home use instead.
