Automatic recharging when state of charge is low

If PV charging is not occurring and the state of charge (SOC) falls below a specified value, automatic recharging from the utility grid takes place.

For modules with a firmware version ≥ 1.1.52.R, the following also applies:

If recharging from the utility grid is not possible (e.g. due to a defect in the hybrid inverter, temperatures being too low or a grid incident), the DC switch will automatically disconnect after a waiting period of 30 minutes. This measure is intended to protect the battery and prevents a deep discharge. The fuse must be reset manually when the necessary operating parameters (e.g. grid fault is no longer present or the temperature is above 0°C) are met again.
