Fox ESS H1-5.0-E-G2 inverter
Fox ECS2900-H4 battery 11.52KW

If I set a charging schedule from 0400 to 0700 (with mode scheduler) , and the battery reaches 100% at 0600, then from 0600 to 0700 the system prevents the battery from discharging, so that any load on the house has to be powered from the grid. Am I right that this is how the system currently works?

If so, then if my heat pump is operating between 0400 and 0700, I will be both charging the battery and running the heat pump from the grid. If the battery reaches 100% at 0600, then between 0600 and 0700 the battery will not discharge, and the heat pump will still be powered from the grid. But I could be running the heat pump from the battery between 0600 and 0700, so I am paying an unnecessary amount for grid use in the that hour.

Am I right with that reasoning? If yes, then is there any way of switching off the remainder of the charge period when the battery reaches 100%? In the example, this would mean allowing the battery to discharge from 0600.

If 0400-0700 is a cheap period of electricity, I would NOT want the battery to discharge any energy.
The idea is to start the higher price time with 100% to ride out the period until the next cheap energy session.

Are you on Octopus Cosy?
Three cosy periods of super cheap rates between 04:00 - 07:00, 13:00 - 16:00 and 22:00 - 00:00 every day

Perhaps if you can let us know what Country/Company/Tariff you are on, then the question can be answered easier.
There exists Home Automation systems, that could probable be set to swap the system mode when it reaches 100% to allow the battery energy to be used.
