Commercial Battery Storage Explained

See how battery storage can help your business store excess solar energy, add batteries to an existing solar PV system, or make use of cheaper off-peak electricity tariffs where suitable.

Commercial Solar Battery Storage

Commercial Battery Storage for Businesses With or Without Solar Panels

Commercial solar battery storage helps businesses take greater control of the energy they generate, store, buy and use.

For businesses with commercial solar panels, battery storage can store excess solar energy during the day so it can be used later when the business needs it most. For companies planning a new commercial solar PV installation, battery storage can be designed into the system from the beginning. For businesses without solar panels, commercial battery storage can also be used to charge from the grid during cheaper off-peak or economy tariff periods, then discharge during more expensive periods where suitable.

New Solar PV + Battery Storage

For businesses planning a new commercial solar panel installation, battery storage can be designed into the system from the beginning.

  • Generate renewable electricity during the day
  • Store surplus solar energy for later use
  • Improve solar self-consumption
  • Plan around future energy demand
2

Battery Add-Ons for Existing Solar

If your business already has commercial solar panels, a battery may help you store more of the energy you currently export.

  • Make better use of existing solar panels
  • Store unused daytime generation
  • Use solar energy later in the day
  • Improve the value of your solar PV system

Cheaper Tariff Battery Charging

Commercial battery storage can also be used without solar, charging from the grid during cheaper off-peak or economy tariff periods where suitable.

  • Charge when electricity is cheaper
  • Discharge during more expensive periods
  • Support tariff optimisation
  • Use with or without solar panels
The right commercial battery storage solution depends on your usage profile, tariff, operating hours, site layout, electrical infrastructure and long-term energy plans.

Commercial Battery Storage Installed by a Fox ESS Elite Installer

Positive Energy Solutions is a Fox ESS Elite Installer, giving businesses confidence that their battery storage system is being designed and installed by an experienced renewable energy team.

Fox ESS battery and inverter technology can be used in suitable commercial solar PV and energy storage projects, including new solar and battery systems, retrofit battery add-ons, and battery storage designed around business electricity usage and tariff management.

Your business is not simply buying a battery. You are investing in a properly planned energy storage system that needs to work with your building, solar PV system where relevant, electricity tariff, operating hours and future goals.

Why It Matters

Make Your Commercial Energy System Work Harder

A well-designed commercial solar battery storage system can help your business make better use of the electricity available to it.

Battery storage is not about adding equipment for the sake of it. It is about matching generation, storage, usage and tariffs more intelligently so your business can make better energy decisions.

Store Excess Solar Energy

Store surplus solar power for later use instead of exporting it straight back to the grid.

Improve Self-Consumption

Use more of the renewable electricity generated by your own commercial solar panels.

Use Cheaper Tariffs

Charge batteries during cheaper tariff windows where suitable, then use stored electricity later.

Reduce Grid Reliance

Use stored solar energy or stored off-peak electricity at certain times of the day.

Support Future Demand

Battery storage can support wider plans such as EV charging, expansion or increased electricity use.

Smarter Energy Management

Design your commercial energy system around how your business actually uses electricity.

Suitable Businesses

Who Is Commercial Battery Storage Suitable For?

Designed Around Your Usage

A commercial battery should not be sized by guesswork. It should be designed around your real electricity usage, peak demand, operating hours, import and export profile, tariff structure and future plans.

Honest Suitability Advice

Positive Energy Solutions will only recommend commercial solar battery storage or commercial battery storage where we believe it is suitable for your site and your needs.

AC-Coupled vs DC-Coupled

AC-Coupled and DC-Coupled Commercial Battery Storage

Commercial battery storage systems are commonly designed as either AC-coupled or DC-coupled systems. The right choice depends on whether the battery is part of a new solar PV system, added to an existing solar installation, or used as standalone commercial battery storage.

AC-Coupled Battery Storage

AC coupled commercial battery storage system diagram

An AC-coupled battery system is often a practical option when adding battery storage to an existing commercial solar PV system. It can often be retrofitted without replacing the whole solar setup.

AC-coupled systems may also allow batteries to charge from solar and the grid, depending on the system design.

DC-Coupled Battery Storage

DC coupled commercial battery storage system diagram

A DC-coupled battery system is often considered when designing a new commercial solar and battery storage system from the beginning.

This can reduce conversion stages in some designs, but it may be more complex to retrofit into an existing commercial solar PV installation.

There is no single best answer for every business. Positive Energy Solutions will assess your site, existing equipment, electricity usage and goals before recommending the most suitable battery storage approach.

Commercial Battery Storage FAQs

Frequently Asked Questions

Can commercial battery storage be added to existing solar panels?

Yes, in many cases commercial battery storage can be added to an existing commercial solar PV system. The suitability depends on your current inverter, electrical setup, export levels, usage profile and site requirements.

Can a business use battery storage without solar panels?

Yes. Commercial battery storage can be used without solar panels. Some businesses use batteries to charge from the grid during cheaper off-peak or economy tariff periods, then discharge during more expensive periods where suitable.

What is the difference between commercial solar battery storage and commercial battery storage?

Commercial solar battery storage usually refers to a battery system connected to a commercial solar PV installation. Commercial battery storage is broader and can include standalone battery systems that charge from the grid, with or without solar panels.

Are Positive Energy Solutions Fox ESS installers?

Yes. Positive Energy Solutions is a Fox ESS Elite Installer. We can design and install suitable Fox ESS battery storage systems for commercial projects, including new solar PV systems, battery add-ons for existing solar installations and commercial battery storage designed around business energy usage.

Can a commercial battery charge from cheaper economy tariffs?

Yes, some commercial battery storage systems can be designed to charge from the grid during cheaper tariff periods. Whether this is suitable depends on your electricity tariff, battery system, site demand and the price difference between tariff periods.

Is commercial solar battery storage only for large businesses?

No. Commercial solar battery storage can be suitable for different types of businesses, from smaller commercial premises to larger industrial sites. The system size and design should be based on your electricity usage, tariff and site requirements.

What size commercial battery does my business need?

The right battery size depends on your electricity usage, solar generation, peak demand, operating hours and goals. A battery should be sized around your real energy profile, not guessed.

Does commercial battery storage provide backup power during a power cut?

Not all commercial battery storage systems provide backup power automatically. Backup capability requires specific system design and equipment. If backup power is important for your business, this should be discussed at the design stage.

Is AC-coupled or DC-coupled battery storage better?

It depends on the project. AC-coupled battery storage is often practical for adding batteries to existing solar PV systems. DC-coupled battery storage can be efficient for some new solar and battery installations. The best option depends on your site and goals.

Do you install commercial battery storage across the UK?

Yes. Positive Energy Solutions works with commercial and industrial clients across the UK.
