Battery Storage Systems
Store cheap daytime power and spend it when the grid gets expensive — or disappears.
Commercial battery energy storage systems (BESS) capture surplus solar or off-peak grid power and release it exactly when you need it — shaving demand charges, bridging outages seamlessly, and squeezing far more value out of every kilowatt-hour your business already pays for.
01 — Overview
Power on your schedule, not the grid’s
- Sized in kW and kWh to your load
- Lithium-iron-phosphate (LFP) chemistry
- Pairs with solar or stands alone
- Seamless backup and peak shaving

02 — Applications
Where this technology is applied
The settings we most commonly deploy this system in, and the duty it performs in each.
Peak shaving
Discharges into your monthly demand peak to cut capacity charges that energy-efficiency measures alone cannot reach.
Solar self-consumption
Stores midday solar surplus for use after dark, so more of your own generation offsets expensive grid power.
Seamless backup
Bridges grid outages within a fraction of a cycle, keeping servers, cold chain and production running without a generator’s start-up jolt.
Time-of-use arbitrage
Charges on cheap off-peak or solar energy and discharges through expensive peak hours, banking the price difference daily.
Grid-edge stability
Smooths voltage and supports sites on weak or unreliable grid connections, protecting sensitive equipment.
Solar-plus-storage microgrids
Anchors an on-site microgrid that can island from the grid entirely during extended outages.
03 — Outcomes
Turn stored energy into saved money
- Demand charges cut at the peak
- Critical loads ride through outages
- More of your own solar self-consumed
- A tariff hedge that pays every month
A battery turns electricity from something you must use the instant you buy it into something you can store and spend deliberately — and that shift unlocks value in several directions at once. The most immediate is demand-charge reduction: many commercial tariffs bill heavily on your highest peak of the month, and a battery quietly discharges to flatten that peak, cutting a charge most businesses cannot otherwise touch. Paired with solar, storage lets you self-consume far more of your own generation instead of exporting it cheaply and buying it back dear after dark, sharply improving the payback on the whole system. It is also a seamless backup: where a generator starts with a jolt and a delay long enough to crash servers, a battery bridges an outage instantly and silently, protecting production, data and revenue. And as a tariff hedge, every rise in the price of peak power increases what your stored energy is worth. The engineering is mature and increasingly affordable, LFP chemistry is safe and long-lived, and a well-configured system works away every single day — shaving, storing and protecting — rather than sitting idle until a failure. The one discipline that matters is honest sizing: a battery pointed at the wrong duty is expensive, which is why we design against measured load, not assumptions.
Best suited to
- Businesses facing significant demand (capacity) charges on their tariff
- Sites with solar exporting surplus cheaply by day
- Operations needing seamless, silent backup for critical loads

05 — Delivery
The installation process
Every installation follows the same engineered sequence, from first survey to commissioning and handover.
We start by metering your load at interval resolution — establishing your demand-charge peaks, your outage exposure and how much surplus solar (if any) you currently export or waste.
From that data we size the system in two dimensions that matter independently: power (kW) for how hard it must discharge, and energy (kWh) for how long — a peak-shaving duty and a backup duty size very differently.
We specify lithium-iron-phosphate (LFP) cells for their safety, cycle life and tolerance of heat, matched to a hybrid or battery inverter and an energy-management system that decides when to charge, hold and discharge.
The control strategy is configured to your tariff and goals — charging off cheap solar or off-peak grid, discharging into expensive peak hours, and always holding a reserve for backup if continuity is a priority.
For backup duty, we design the changeover so protected circuits see no interruption when the grid fails — the transition happens within a fraction of a cycle, faster than equipment can notice.
Installation covers the battery enclosure, inverters, protection, isolation and metering, all to standard, with thermal management appropriate to the site.
We commission against the model — verifying real charge/discharge behaviour, changeover performance and the savings logic — configure remote monitoring, and hand over with the reporting you need to see the system earning.
