Battery Storage — Green Guardians

Battery storage that earns its keep

Solar generates in the day. Most homes use most of their power in the evening. Battery storage closes that gap, capturing what you would otherwise export cheaply and giving it back after dark, overnight, and on dull days.

The Case For Storage

Use more of what you generate

Without a battery, a typical home uses only a third of what its panels produce. The rest is exported, often for far less than you pay to buy power back in the evening. Storage flips that: it can lift self-consumption toward two-thirds or more, which is where the savings actually come from.

We fit lithium iron phosphate (LFP) batteries: chemically stable, long-cycle, and free of the thermal-runaway risk of older lithium types. Intelligent charge management learns your usage and adapts automatically, prioritising stored solar when it is most valuable.

Add optional whole-home backup and the lights stay on through a grid outage. Every unit we supply carries a 10-year manufacturer warranty as standard.

Storage that thinks ahead

Daytime capture

Surplus generation charges the battery instead of being exported at a low rate.

After-dark supply

Stored energy covers evening and overnight demand, typically 70 to 100 per cent of it.

Intelligent charging

The system learns your patterns and adapts charge and discharge automatically.

LFP chemistry

Stable, long-life lithium iron phosphate cells with no thermal-runaway risk.

Optional backup

Keep essential circuits, or the whole home, running through a power cut.

10-year warranty

Manufacturer-backed cover as standard on every unit we install.

A battery install comes with

Sized to your generation and usage, not just the biggest unit we can sell you.

  • Usage and generation review to size the battery correctly for your home.
  • LFP battery supply and fitting with intelligent charge management configured.
  • Hybrid or AC-coupled integration matched to your existing or new inverter.
  • Optional backup wiring for essential circuits or whole-home cover.
  • Monitoring integration so stored and used energy show alongside generation.
  • 10-year manufacturer warranty registered on your behalf.

Generating more than you use? Store it.

If you are exporting cheap and buying back dear, a battery is usually the single biggest improvement you can make. Let us run your numbers.
