Storage sizing and load analysis
What actually runs after dark, including the bore pump on a float switch and the freezer nobody counts.

Battery Installations That Carry the Property Overnight
Storage sized against your real overnight and bad weather load, installed and commissioned by a licensed electrician who works on rural properties every week.
Storage Is What Makes Solar Useful After Dark
Generation gets the attention, but on a rural property the battery bank is what decides whether the lights, the pump and the cool room keep running at three in the morning.
CW Rural Power & Electrical sizes, installs and commissions battery storage for off grid and grid connected properties across New South Wales and Queensland. The sizing question is the one that matters. A bank that is slightly too small gets cycled deep every single night, and a battery worked that hard will not see anything close to its rated life.
Getting the number right at the start is far cheaper than replacing a bank early, which is why we measure the load rather than working from a rule of thumb.
What a Battery Installation Includes
Specified, installed, commissioned and documented.
Battery supply and installation
Chemistry and capacity matched to cycle depth, expected life and the temperature the bank will really sit in.
Bank replacement and upgrades
Replacing tired banks and expanding storage on properties that have outgrown the original install.
Hybrid inverter and charger install
Storage the inverter cannot properly charge or discharge is capacity you paid for and cannot use. We match the pair.
Enclosure, ventilation and mounting
Dry, ventilated, protected from extreme heat, secure, and accessible for service. Usually a plant area, not a sunny wall.
Protection, isolation and signage
Installed to the Australian standards covering placement, clearances, protection and labelling, with documentation handed over.
How the Job Runs
Measured, specified, installed, tested.
Work out the overnight load
We measure what the property draws after dark rather than estimating it, because standby loads and pumps quietly dominate the number.
Set the autonomy target
How many low sun days the bank has to ride through. That decision drives capacity more than anything else.
Specify the bank
Capacity sized so the bank sits within the cycle depth its rated life assumes, with the inverter and charger matched to it.
Install
Mounting, enclosure, ventilation, clearances, isolation and protection, all to standard and all labelled.
Commission under load
Tested properly rather than switched on and left, with monitoring configured so you can see what the bank is doing.
Hand over and support
Documentation you can hand to the next electrician, and a number to call when something changes.
Adding Storage to an Existing System
Plenty of rural properties already have solar and want to stop running the generator every evening. Whether that is simple depends almost entirely on the inverter. Some units support storage directly, some need a hybrid replacement, and some older installations are better rebuilt than extended.
We assess what is there and give you a straight answer, including when the answer is that it is not worth it. For the wider picture see off grid power systems, and for generation see off grid solar.
Why CW Rural
Storage that reaches the life it was sold with.
Sized to last, not to quote
A bank slightly too small gets cycled deep every single night and dies years early. Sizing it right at the start is the cheapest thing on the invoice.
Specified for where it lives
Heat is what kills batteries on rural properties. We specify for the shed the bank will actually sit in, not for a lab bench.
Labelled and documented
Every install is labelled and documented, so a fault in five years is a short visit rather than an afternoon of tracing.

Battery Storage Questions
How much battery storage does a rural property need?
Enough to carry the property’s overnight load plus an agreed number of low sun days without cycling the bank deeper than its rated life assumes. We work that number out from measured consumption rather than a rule of thumb, because pumps and refrigeration change it enormously.
How long do batteries last?
Modern lithium banks are commonly rated for a decade or more, but real life depends heavily on how deeply they are cycled and how hot they get. A bank that is undersized for the property will be worked hard every night and will not reach its rated life. Sizing correctly at the start is the cheapest way to extend it.
Can I add batteries to an existing solar system?
Often yes. It depends on the inverter already installed and whether it supports storage or needs replacing with a hybrid unit. We assess what is there and tell you plainly whether adding storage is straightforward or whether the inverter is the real constraint.
Where should batteries be installed?
Somewhere dry, ventilated, protected from extreme heat, secure, and accessible for service. On rural properties that is usually a dedicated plant area in a shed rather than an outside wall in full afternoon sun, which shortens battery life considerably.
Do battery installations need to meet specific standards?
Yes. Battery installations are covered by Australian standards addressing placement, clearances, protection and signage, and the work must be done by a licensed electrician. We install to those requirements and leave you with the documentation.
Will storage let me stop running the generator?
That is usually the goal, and with a correctly sized bank paired to adequate generation most properties end up starting the generator rarely rather than nightly. We will tell you at quote stage what is realistic for your load and your site.
