Octopus Flux battery strategy
Octopus Flux only works well when battery charging, reserve and export behaviour are coordinated properly, because export value is only part of the economics.
Private beta rollout
Use this page as an operating guide, not a supplier rate card.
Tariff rates, eligibility rules and regional pricing move over time. The useful part of this page is the operating logic: which homes suit the tariff, where conflicts appear, and what you should verify before acting.
Your hardware changes the answer
Battery, EV, solar and heating all interact with the same tariff in different ways, so the home-level pattern matters more than the headline unit rate.
Check the current supplier terms
Treat the fact block below as a dated summary and confirm current rates or eligibility on the supplier page before switching.
Use the CTA only after the page is useful
The product mention belongs after the tariff tradeoffs are clear, not before.
Key facts to verify
- Flux is built for solar-and-battery homes rather than import-only EV charging setups
- The tariff uses fixed daily import and export windows rather than fully half-hourly pricing
- Export profitability depends on replacement import cost, refill opportunity and battery wear, not just the headline export rate
- It is worth comparing Flux with current Outgoing pricing as export products change over time
- Best suited to households that can deliberately plan charge, reserve and discharge around the daily windows
Facts last checked on 11 March 2026. Rates and eligibility can change by region and over time.
What makes this tariff hard
Flux introduces import and export decisions that can look good in isolation but fail once solar uncertainty, home demand and evening usage are considered together.
Best fit households
What strong control looks like on this tariff
- Track import price, export value and net household outcome in one place.
- Understand when export optimisation is genuinely profitable versus when reserve protection should win.
- Compare battery charging from cheap windows against expected daytime solar and evening consumption.
- Spot when the home is exporting too aggressively and later buying back expensive grid power.
Where homes usually go wrong
- Export value can tempt households into depleting reserve too early.
- Profitability depends on actual demand and refill opportunity, not tariff name alone.
- Flux is strongest when the battery strategy is integrated with the rest of the home energy stack.
Integrations that fit this tariff
These integration pages explain which devices are most likely to benefit from this tariff’s control and reporting logic.
Solis
Connect Solis hybrid inverters to 1app.energy to see live solar, battery, grid and home demand in one place, then automate battery charge decisions around tariff windows.
Enphase
Connect Enphase systems to bring microinverter solar data into the same decision layer as tariffs, batteries, EV charging and heating demand.
Octopus Energy
Connect Octopus tariffs to turn raw device telemetry into cost-aware actions, daily savings reporting and smarter battery decisions.

Solar and battery optimisation for smart tariffs
This is the core 1app.energy use case: understanding whether solar, battery reserve and tariff timing are working together or fighting each other.
Using battery storage to buffer heat-pump demand
For all-electric homes, battery storage can protect comfort and cost, but only if the reserve strategy is tuned to real heating behaviour and tariff opportunity.
Whole-home conflict detection for modern energy homes
The more flexible devices a home has, the more valuable it becomes to detect conflicts between them before they show up as cost, lost solar or poor comfort.
Smart controls that usually fit this tariff
These mode pages explain how the battery can behave on this tariff once reserve, export, and whole-home demand are included.
Autopilot
The best starting mode for most homes. Autopilot decides when to charge, hold, or export by balancing tariff value, home coverage, refill confidence, and your protected minimum battery SoC. Choose Balanced for a calmer default or Aggressive for stronger value seeking.
Home First
A simpler home-first mode. It prioritises running the home from your own solar and battery first, minimises grid dependence, and avoids optimiser-led battery export.
