• Arun’s Price Efficiency Adjustment is reducing his base electricity rate by about 10c to 11c/kWh.
• Arun runs appliances and charges his EV and plug-in hybrid during the day, then schedules his battery to export during Happy Hour while keeping a 25% reserve to power the home overnight.

A busy household, with a plan for its power

Arun’s home has plenty to power: a family of three, one electric vehicle, one plug-in hybrid, a pool pump running daily and air conditioning to keep the household comfortable through a Queensland summer.

With a 13.2kW solar system and a 24kWh battery, Arun has built a routine around when his household uses, stores and exports electricity.

Happy Hour’s feed-in tariff first caught his attention. So did being able to decide how his battery operates.

“I enjoy the flexibility of being able to control how my battery charges and discharges on a daily basis depending on my needs, whilst also allowing me to set a regular schedule to maximise my feed in earnings.”

Making the most of the middle of the day

Arun runs the dishwasher and washing machine during the day. His pool pump is on a timer between 9am and 1pm, and he aims to charge both vehicles while the sun is up to make the most of his solar.

His approach is not about putting family life on hold. It is about choosing when the dishwasher runs, when the vehicles charge and how much energy stays in the battery for later.

Exporting in the evening, keeping a reserve for home

Arun has set his battery to discharge during the Happy Hour export window between 5:30pm-9:30pm, with a 25% cut-off. That lets him export stored energy while keeping part of the battery available for the household overnight.
He says his battery is large enough to cover the household overnight without drawing from the grid.

For Arun, the appeal is that balance: a regular export schedule, with the flexibility to adjust charging and discharging around his family’s needs.
