Energy Storage
Store the power you generate. Use it when it matters.
Battery systems sized around the loads you actually need to keep running, and the hours you need to keep them running for.
Backup is a question about loads and hours, not about kilowatt-hours.
The useful question is never "how big a battery should I buy". It is "what has to stay on, for how long, and what happens when it starts". Answer those and the capacity follows. Answer them the other way round and you get a battery that either costs more than it needed to or gives out sooner than you expected.
What we do
Where the work actually happens.
Each of these is a stage we are accountable for, and each one appears in your scope of work.
Load and duration study
Which circuits are essential, what they draw running, what they draw starting, and how long they need to be held up.
Battery sizing and chemistry
Capacity, usable depth of discharge, expected cycle life and thermal behaviour — chosen against your duty cycle, not a headline number.
Hybrid and backup inverters
Inverter topology and transfer behaviour selected so critical loads ride through an outage the way you expect them to.
Essential-load separation
Reworking the distribution board so backup carries what it should, and does not silently carry what it should not.
Protection and ventilation
Isolation, protection and enclosure conditions appropriate to the chemistry and the location — an electrical room is not a cupboard.
State-of-charge visibility
Monitoring so you know what reserve you have before an outage, not after it.
What determines the outcome
The things that decide whether this works.
These are the questions we work through with you. They are also the questions worth putting to anyone else you are speaking to.
Starting current is what catches people out
Motors and compressors draw several times their running current for a fraction of a second. A battery and inverter sized only on running load will trip the moment a pump or an air conditioner starts.
Usable capacity is not rated capacity
How much of a battery you can actually use, cycle after cycle, without shortening its life depends on chemistry and on the management system. Two batteries with the same number on the label can differ substantially in what they will give you.
Cycle life is a function of how you use it
Depth of discharge, temperature and charge rate all affect how long a battery lasts. A system designed for occasional deep backup and a system designed for daily cycling are not the same system.
Storage and solar are better designed together
Retrofitting storage onto an existing solar system is often possible but rarely as clean as designing the two together — inverter compatibility and the existing protection scheme both constrain what can be done.
Energy Storage
Questions we get asked.
Do I need a battery if I already have solar?
Only if you need power during an outage, or if your tariff makes it worth shifting consumption into the evening. Solar without storage still reduces your bill; storage adds resilience and time-shifting, and it is a separate decision with its own economics.
How long will a battery back my property up for?
That depends entirely on what you keep running. The same battery might hold lights, fans and a refrigerator for many hours, or an air conditioner for a fraction of that. Our backup calculator gives you a starting figure, and a site visit gives you a real one.
How long does a battery last?
Manufacturers state life in cycles at a defined depth of discharge and temperature. The honest answer for your system is the manufacturer’s stated figure for the specific product quoted, applied to your actual duty cycle — which is why we put both in writing rather than quoting a round number of years.
