STORAGE FOR BUSINESS
Commercial batteries
Storage sized to your tariff, not to a brochure: it shaves demand charges, shifts cheap daytime solar into the evening, and keeps the loads that matter running through an outage.
Demand charges
Many commercial tariffs bill your peak half hour as well as your energy. A battery that trims that peak can pay for itself on the demand line alone, and the tariff decides whether it does.
Solar you would otherwise export
Evening trade, cool rooms and after-hours loads run on daytime solar stored rather than sold back for cents.
Backup for what matters
Refrigeration, tills, servers, gates: the circuits you nominate stay up through an outage, and the rest wait.
Three-phase and stackable
Systems that grow in modules and sit on three-phase supply, so the first stage does not limit the second.

WAYS TO PAY
Own it, finance it, or buy the power.
Buy it outright
The simplest and usually the best return: you own the system and every kilowatt hour it makes from day one.
Finance through our partners
Spread the cost so the monthly repayment sits under the monthly saving. We introduce you to the lender; the decision is yours.
Ask about a lease or power purchase agreement
For larger sites, a third party can own the system and sell you the power at a fixed rate. We will tell you plainly whether it suits your site.
Tax treatment, depreciation and any instant write-off depend on your business: we do not give tax advice, and your accountant should have the final word on how you buy.
AFTER THE INSTALL
Looked after for the life of the system.
Monitoring you can see
Generation and consumption on a portal or app, with alerts when a string or an inverter drops out.
Performance checks
A yearly look at yield against design so a dirty array or a failed optimiser never costs you a season.
Warranty handled for you
One call to us for any product or workmanship claim. We deal with the manufacturer.
Cleaning and inspections
Panel cleaning, thermal and electrical inspections on a schedule that suits your site.
A FEASIBILITY CHECK, FREE
Tell us about your site.
Send what you have; a recent bill and a rough roof size are enough to start. We come back with whether it stacks up, and what we would need to design it properly.
Prices on this website are for the ACT and within 35 km of Canberra. Further out, the same system usually costs 15–30% more for travel, time away and the extended warranty responsibility that comes with distance. We confirm the final price before you commit to anything.
