ANOTHER WAY TO COMPARE VALUE

What does each warranted kWh cost?

MARKET AVERAGES

Capacity tells you how much a battery can hold at once. Warranted throughput measures the cumulative energy covered by its warranty terms.

Usable battery capacityInstalled cost per warranted kWh · AUD
  • 16–20 kWhA$0.28 / kWh
  • 20–30 kWhA$0.23 / kWh
  • 30–40 kWhA$0.21 / kWh
  • 40–50 kWhA$0.20 / kWh
Installed price÷Warranted energy throughputConvert MWh to kWh: × 1,000=Cost per warranted kWh

Read the warranty together. Check the time limit, throughput allowance, retained capacity and usage conditions. A 10-year warranty does not mean unlimited energy throughput.

A comparison measure. This is not the electricity tariff or a guaranteed lifetime energy cost. Charging costs, losses and actual use also affect the value you receive.

01 / THE PRICE, UNPACKED

What does the price include?

Think of an installed battery as a complete system. Check these parts in your written quote.

Battery

The exact model and number of modules.

Inverter

The equipment that manages charging and power.

Installation

Mounting, electrical work and commissioning scope.

Handover

Monitoring setup and warranty information.

Equipment + agreed installation including GSTApplicable rebate check whether already deductedYour quoted total

02 / SAME BATTERY. DIFFERENT HOME.

What can change the total?

Five things that can turn a starting price into a different installed quote.

01

Switchboard

Limited space or electrical work can change the scope.

HELP US CHECKSend a clear photo of the whole board.
02

Location & cable route

Distance, access, mounting and protective barriers affect the work required.

HELP US CHECKShow the proposed position and the route to the board.
03

Blackout backup

Essential circuits and larger loads need different equipment and wiring.

HELP US CHECKList what you want to keep running.
04

Existing solar

Keeping, replacing or expanding equipment changes the project.

HELP US CHECKShare the inverter model and solar size.
05

Additional equipment

New panels, EV charging and other additions are separate choices.

HELP US CHECKAsk for each optional item to be priced separately.
