Weather-aware
Anticipate how much solar energy tomorrow may deliver, rather than relying on yesterday's pattern.
Independent battery management for smarter savings, battery care and home-specific automation.
Seeing tomorrow. For homeowners, manufacturers and installers.
From energy retailers and manufacturers.
Household data used only to optimise for the specific customer.
Optimised automation without unnecessary stress.
01 / Why Metis
A battery doesn't automatically know tomorrow's electricity prices, weather or household demand. Metis brings those signals together to make each day count.
Independent from your energy retailer and battery manufacturer.
Uses your tariff, weather forecast and home-specific learning to plan battery use.
Intelligent automation for compatible, appropriately sized systems.
Balanced optimisation designed to avoid extra battery stress versus a smart seasonal static plan.
02 / Why this service exists
Default operation can miss opportunities—or cycle the battery when the potential saving is too small to justify it.
Anticipate how much solar energy tomorrow may deliver, rather than relying on yesterday's pattern.
Respond to low-cost and expensive electricity windows under an ordinary time-of-use tariff.
Learn from the information you choose to share, only to optimise for your own home.
03 / Simple, transparent process
Five straightforward steps. You authorise management of your battery, and you can choose to leave Metis at any time.
Metis
Checks compatibility and likely value for your home.
Customer
Reviews expected savings, fees and estimated benefit after fees.
Customer
Authorises Metis to manage the battery.
Metis
Applies a daily schedule within your battery's operating limits.
Customer
Views schedules, savings estimates and battery-care evidence.
You can leave at any time and return to normal battery operation without Metis.
04 / Balanced battery optimisation
Metis compares both electricity savings and battery stress against the same smart seasonal static baseline.
Repeats a simple, well-chosen plan for the season. Easy to understand and a fair benchmark.
Hold a reserve overnight, charge from solar when available and discharge through the evening peak.
Adapts to tomorrow's tariff, weather and household demand. Designed to avoid added stress versus the baseline.
Cloudy afternoon, costly evening: use cheap overnight power, preserve energy for the peak and avoid low-value daytime cycling.
Electricity savings, Battery Stress Index (BSI) evidence against the seasonal baseline, and fees paid. Continue Balanced optimisation—or return to the baseline.
05 / Battery stewardship
The Battery Stress Index is intended to help make battery care visible—not just electricity bill savings.
Daily BSI: compares battery stress with your smart seasonal static plan. Lower is better.
A safeguard: designed to adjust the schedule or fall back to the baseline if accumulated stress remains higher.
Monthly value: see estimated savings against the baseline alongside fees paid.
BSI is an engineering indicator of relative stress, not a quantified guarantee of longer battery life. Availability of features depends on the system integration and product rollout.
06 / Transparent value
Two illustrative households from the Metis overview. Compare examples below—these are not forecasts or guaranteed outcomes for your home.
Compared with a smart seasonal static plan, before Metis fees.
Illustrative savings only. Solar, battery size, electricity demand and tariff windows affect results. Individual outcomes require a home-specific assessment.
Compare estimated electricity savings with the smart seasonal plan, before and after fees.

Use the daily BSI to understand relative battery stress and the safeguards intended to reduce it.

Choose how much extra information to share at any time. It is used only to optimise for you.
07 / Working together
Value for homeowners, battery manufacturers and installers—each with a clear role to play.
Lower electricity costs where there is real value to unlock—with battery stewardship built into the design.
Bring tariff-aware intelligence to compatible systems while respecting the manufacturer's operational constraints.
Pair right-sized hardware with a service that aims to make its value clearer over time.
You choose the right-sized hardware. Metis manages it with battery-care safeguards and clear savings and stress reporting.
