Weekly full charge

Charges batteries to 100% once a week to balance the cells and maintain battery health (cell balancing).

Behaviour

1. On the configured day of the week, if the usual max SOC is below 100%, the integration temporarily raises the charging cutoff limit to 100%.
2. The battery charges until it reaches 100% SOC.
3. Once 100% is reached, the max SOC limit automatically reverts to the user's configured value.

Interaction with solar charge delay

If solar charge delay is active, the weekly charge is postponed while the forecast solar production is sufficient to reach 100%. The battery only starts grid charging when the solar model determines that the sun will not complete the charge.

Modbus register involved

This feature manipulates register 44000 (charging cutoff) to temporarily raise the limit.

Info

This feature is available for all supported battery versions (v2, v3, vA, vD).
