Solar battery health check
A home battery is one of the most expensive parts of your energy setup, and it works quietly in the background – so problems often go unnoticed until the bills creep up. A specialist battery health check tests capacity, firmware, charge settings and backup, checks the installation against the battery standard, and gives you a clear report. Any brand, any installer.
- Capacity, firmware and settings tested
- Charge schedule tuned to your tariff
- Free check-up at two years for our own customers

Quick question
Is your battery still pulling its weight?
A battery that’s half-charging or set up wrong for your tariff can cost hundreds a year without you noticing.
Why get your battery checked?
Batteries need very little attention – but the attention they do need makes a real difference.
Get the savings you paid for
Wrong charge windows or reserve settings can leave stored energy unused at peak times.
Catch capacity loss early
Some capacity loss is normal with age. Faster loss can point to a fault that may be a warranty claim.
Stay on current firmware
Manufacturers release updates that fix bugs and improve performance and safety.
Make sure backup works
Find out before the next blackout, not during it.
Keep the install safe
Checks against AS/NZS 5139 for clearances, ventilation and protection.

Battery health check FAQs
How often should a home battery be checked?
Every two years suits most homes. Our own customers get a free routine check-up two years after installation.
Do you check batteries installed by other companies?
Yes. We check FoxESS, GoodWe, Sungrow, Sigenergy, Growatt, Alpha ESS, SOFAR and other brands.
Is it normal for a battery to lose capacity?
Yes, a little each year is normal. Faster loss than the warranty allows can point to a fault, and a health check gives you the evidence for a claim.
Can you change my battery settings to save more?
Yes. We set charge and discharge windows and reserve levels to suit your tariff and when you use power.
Will a health check update my firmware?
Where the manufacturer recommends it, we update battery and inverter firmware during the visit.
How quickly can you come out?
Our two full-time service staff answer your call and start resolving issues within five working days. We work Monday to Saturday, 9am to 5pm.
