Battery storage

Buy cheap. Use at peak. Sell the rest.

A battery makes your energy an asset around the clock — storing cheap or self-generated energy and deploying it at the hours that decide your bill.

Your energy, around the clock.

One day, forty-eight decisions. Nova AI buys and stores energy while it’s cheap, spends it through the expensive hours, and sells the surplus when the grid pays most.

Battery state of charge 30%

Overnight — cheap grid energy fills the store. Daytime — solar tops the battery up while prices sag. Evening peak — the site runs on stored energy, not the grid. The spike — surplus sold when the grid pays most.

The money

How a commercial battery pays for itself.

2–5year payback, modelled on your half-hourly data before you commit

100%year-one tax relief available on qualifying spend via capital allowances

Grid-tied storage

Grid-tied storage: cut peak-rate import every day.

Stores excess solar for when production is low, shaves your peaks, and supplies the grid when demand — and price — is high. The configuration most commercial sites need — like the 300kWh retrofit at the LWC Drinks depot in Liverpool, our largest commercial battery to date.

Micro-grid

The micro-grid. An island when it needs to be.

Panels, inverters, optimisers and battery forming a localised grid — connected to the mains, or running autonomously in island mode through outages and failures.

Hybrid with generator

Battery plus generator. Power, whatever the weather.

Battery plus generator backup for off-grid or grid-limited sites — like the 417.6 kWp grain-store system we integrated with an existing 550kVA genset. Grid refused or constrained? Power your site without the grid →
