Energy Storage

Store the sun. Spend it on your terms.

PrismFlow battery systems convert captured solar into dispatchable power, smoothing demand peaks, hardening sites against outages, and keeping every watt working long after sunset.

Battery Energy Storage

Battery energy storage is the bridge between when you generate power and when you actually need it. PrismFlow designs and installs lithium iron phosphate (LFP) storage systems that capture surplus solar, hold it efficiently, and release it precisely when tariffs spike, the grid falters, or demand outruns daytime generation. The result is a building that runs on its own light-capture economy rather than the utility's schedule.

Why LFP chemistry

We standardise on lithium iron phosphate cells because they deliver the safety, longevity, and thermal stability that serious infrastructure demands. LFP packs tolerate thousands of deep cycles, resist thermal runaway far better than nickel-based chemistries, and hold a flat discharge curve that keeps your inverters and loads stable from full to near-empty.

Every cabinet ships with integrated thermal management and a battery management system that balances cells, tracks state of health, and reports live telemetry into your PrismFlow dashboard. You see capacity, cycle count, and degradation trends in real time, so storage stays a predictable asset rather than a black box.

Right-sizing capacity and power

Sizing storage well means matching two independent numbers: usable energy in kilowatt-hours and instantaneous output in kilowatts. A home riding through evening peaks may need 10-20 kWh, while a commercial site shaving demand charges might need hundreds of kilowatt-hours paired with a high-power inverter stack. We model your interval data to land both figures exactly.

  • Time-of-use arbitrage to charge cheap and discharge when rates climb
  • Demand-charge shaving that trims your most expensive monthly kilowatts
  • Whole-site or critical-circuit backup with seamless islanding
  • Solar self-consumption to keep generated energy on your meter
  • Future-ready cabinets that scale as your loads and fleet grow

Seamless integration with your stack

Storage only earns its keep when it talks fluently to everything around it. PrismFlow batteries integrate natively with our solar arrays, smart inverters, EV chargers, and building controls, all orchestrated through a single monitoring platform. Switchover to backup happens in under twenty milliseconds, fast enough that sensitive equipment never notices the grid blinked.

That same intelligence layer lets your system respond to signals automatically, pre-charging ahead of forecast outages, holding reserve for peak windows, and exposing clean APIs so your storage can later join a virtual power plant. It is smart infrastructure built to keep adding value as the energy landscape shifts.

Frequently asked questions

How long do PrismFlow batteries last?

Our LFP systems are warrantied for ten years and typically retain over 70% usable capacity well beyond that, supporting thousands of deep cycles thanks to the inherent durability of lithium iron phosphate chemistry.

Can storage power my whole site during an outage?

Yes. We can configure whole-site backup or focus capacity on critical circuits, with islanding switchover in under twenty milliseconds so sensitive equipment keeps running uninterrupted.

Will a battery work without solar panels?

Absolutely. Many clients install storage purely for time-of-use arbitrage and demand-charge savings, then add solar later. The system is built to integrate seamlessly whenever generation is added.

How do you decide what size I need?

We analyse your interval meter data to model both usable kilowatt-hours and peak kilowatt output, then size the cabinet and inverter to match your real load profile rather than a generic estimate.
