Flow Power 4Free – Up to 4 Hours Free Every Day
Flow Power 4Free – Up to 4 Hours Free Every Day
Flow Power's 4Free plan is another option worth considering for homes with solar and battery storage.
The plan provides a free electricity window between 11am and 3pm every day, subject to an hourly allowance.
Important Note – Energy Plan Sign-Up
While Sapphire Solar is happy to provide general guidance on battery-friendly energy plans, we are not able to sign customers up to an energy retailer or switch your electricity account on your behalf.
If you decide to change energy providers, you will need to complete the sign-up directly with your chosen retailer. Energy plans, rates, eligibility requirements and promotional offers can change, so we always recommend checking the retailer's current terms and rates for your address before signing up.

Evening Battery Exports
Flow Power's 4Free plan can also reward customers with solar and batteries for exporting electricity during the evening.
Current peak export periods run from 5:30pm–9:30pm, with feed-in rates varying depending on your state.
This creates an interesting opportunity for battery owners:
Charge during the free 11am–3pm period → use stored energy for your home → potentially export available excess energy during the higher-value evening period.
