Intelligent Octopus Flux — Solar & Battery on Autopilot

Intelligent Octopus Flux is Octopus Energy's automated solar and battery optimisation tariff. Instead of you deciding when to charge and discharge your home battery, Octopus takes control of your battery or inverter and manages it for you — automatically charging it when electricity is cheap and discharging it to the grid when prices are high.

The optimisation runs on forecasts of your solar generation, the weather, grid demand, wholesale prices, and your own usage patterns. You set your preferences in the Octopus app — like a minimum battery reserve — and the system handles everything else. A key feature: import and export rates are matched, so you're always paid the same rate for exporting as you pay for importing at that time.

It's the hands-off counterpart to standard Octopus Flux, where you manage your own battery schedule. For compatible systems, Intelligent Flux typically delivers better financial outcomes — because the algorithm reacts to conditions you'd otherwise have to track manually. New to Octopus? Our how it works guide covers switching from start to finish.

Because Octopus needs to control your battery directly, Intelligent Flux only works with a growing list of compatible inverters and batteries — including GivEnergy and other leading brands such as Tesla Powerwall, SolarEdge, Enphase, FoxESS, and Sigenergy. Octopus adds new integrations regularly, so check their current compatibility list before signing up.

To join Intelligent Octopus Flux you'll need:

• A compatible inverter or battery — from Octopus's supported brands list
• A home battery — essential, as the tariff works by optimising its charge/discharge cycle
• Solar panels — the tariff is built around optimising solar generation
• A smart meter (SMETS2) — for half-hourly import and export readings
• Octopus Energy as your import supplier

Earnings depend on your solar array size, battery capacity, location, and how prices move through the year. As a benchmark, the top 12% of Flux users earn £314 or more per year in net export profit — meaning they earn more from exporting than they spend on imports, and their electricity bills effectively go negative.

Intelligent Flux aims to beat what you'd achieve scheduling the same battery manually. Because the algorithm optimises half-hourly using weather, price, and usage forecasts, it typically captures opportunities — like an unusually high-priced evening or an unexpectedly sunny afternoon — that manual schedules miss. Results vary by setup, but for compatible systems it's generally the strongest-earning option Octopus offers.

Combined with solar self-consumption, households on the Flux tariffs can reduce their energy bills by up to 90%. The bigger your solar array and battery, the more there is for the automation to work with.
