A supplier change can make an existing battery schedule financially wrong overnight.
The Short Answer
After changing electricity supplier or tariff, review the battery settings immediately. The cheap charging window, peak period, export rate and even tariff structure may all have changed.
Update the charging schedule
Check the exact start and end times of the new cheap period and make sure the battery schedule matches them.
Review target state of charge
A new tariff may justify charging more or less overnight. Do not carry forward a target that was designed around the old price spread.
Check export assumptions
Solar households should update the export rate used in any optimisation strategy. This can alter the choice between storing solar and exporting it.
Confirm integrations
If the battery platform uses automated tariff data, confirm that the supplier and plan have been changed in the app or energy-management settings.
Key Takeaway
Battery economics depend on the complete energy flow: what electricity costs when you charge, what it would cost when you discharge, what solar export is worth, and how efficiently the battery is used.
Frequently Asked Questions
Will my battery know I changed supplier?
Usually not automatically. Many systems continue following the old schedule until you update the settings or integration.
What details do I need from the new tariff?
Record cheap, day and peak rates, exact time windows, standing charges and export payment.
Should I reset the battery?
A tariff change normally requires settings updates rather than a hardware reset. Follow the manufacturer or installer guidance for your system.
Update My Battery Tariff
Have the battery schedule checked after a supplier or tariff change.
Tariffs, supplier terms and export payments change. Check the current plan details before making a purchasing or settings decision.
