Inverter 2 stays idle while discharging. + +So, even though both inverters *can* both charge and discharge, the optimiser uses inverter 2 only to charge and inverter 1 only to discharge — each inverter ends up doing what it is most efficient at. + +Let's look at the whole battery at once.

Inverter 2 (the 99%-efficient charger) runs at its full +20 kW from the start of the horizon and tapers off in a single partial step once the target is reached — it only ever charges. Inverter 1 (the 95%-efficient discharger) stays idle while the battery fills, then runs at -20 kW late in the horizon — it only ever discharges. Even though both inverters *can* do both, the optimiser specialises each for the operation it is most efficient at. +- **Shared storage** (bottom panel) shows the *single* ``state-of-charge`` sensor that both inverters feed. It starts at the 20 kWh ``soc-at-start``, climbs while inverter 2 charges, reaches and briefly holds the 189 kWh target, and then falls as inverter 1 discharges — bottoming out at the 10 kWh ``soc-min``. This one curve is the combined effect of both feeds, which is exactly what "shared stock" means. + +Plotting the inverters and the shared stock on the same asset chart makes the coordination obvious: the rise in the bottom panel lines up with inverter 2's charging in the top panel, and the fall lines up with inverter 1's discharging. + +The net energy cost over the horizon is small (about 0.066 EUR at 100 EUR/MWh), and reflects only the energy lost to the inverter efficiencies, since charging and discharging happen at the same flat price. + +.. note:: This same pattern generalises beyond two inverters and beyond batteries. Any number of devices can feed a shared stock — for example, several heat pumps charging one thermal buffer — as long as each device entry references the same ``state-of-charge`` sensor and a single entry carries the shared-stock constraints. + +We hope this demonstration helped to illustrate how FlexMeasures schedules multiple feeds into a shared stock. +For modelling a single storage device in more depth, head back to :ref:`tut_v2g`.

This one curve is the combined effect of both feeds, which is exactly what "shared stock" means. -Plotting the inverters and the shared stock on the same asset chart makes the coordination obvious: the rise in the bottom panel lines up with inverter 2's charging in the top panel, and the fall lines up with inverter 1's discharging. - The net energy cost over the horizon is small (about 0.066 EUR at 100 EUR/MWh), and reflects only the energy lost to the inverter efficiencies, since charging and discharging happen at the same flat price. .. note:: This same pattern generalises beyond two inverters and beyond batteries.

This is the charge level you would otherwise have to infer from the power curve. +- **Gas boiler (gas)** runs at exactly 1 kW every single hour.
