Studer Innotec RCC-02, RCC-03 user manual Combi configurations Inverter-Charger

RCC

Level of battery under-voltage at no load {1108}

Allows adjustment of the battery’s low voltage level at which the inverter and smart boost functions are deactivated. This adjustment is applied in the case of a zero charge and is automatically adapted with regard to the power required from the batteries. This configuration is a factory setting for lead-acid batteries. Poor adjustment of this value leads to early ageing of the batteries due to deep discharges.

A.Battery voltage

B.Duration of undervoltage before disconnection {1190}

C.Disconnection due to undervoltage

D.Undervoltage level {1108}

Adjust this configuration using the technical data for your battery.

The battery undervoltage level is automatically adapted to the instantaneous power of the consumers to compensate for internal losses in the battery and cables.

Acoustic alarm of the battery under-voltage {1196}

When the battery is discharged, the inverter stops in order to protect it from deep discharge. Before disconnecting, the inverter indicates this state via a message and activates the acoustic alarm. The alarm goes out when the inverter stops or after a defined duration {1469}

Duration of the acoustic alarm {1469}

The acoustic alarm stops automatically after a certain time and you can adjust the duration using this configuration.

Combi configurations Inverter-Charger {1197}

These configurations manage the combined functions between the charger and inverter. The conditions for passing from one function to another are adjusted in this category.

A.Stoppage of charger operation {1309}

B.Disconnection of transfer subject to delay {1199}

C.Delay before opening of the transfer {1198}

D.Immediate passage to the inverter threshold {1200}

Minimum AC In voltage to authorise the charging {1309}

In the event of sources with limited power output (such as a generator, for example) the use of strong consumers at the output may lead to a drop in voltage. The adjustment of this configuration allows disconnection of the battery charging function and thus maintains the power available to other consumers without influencing the voltage of the source.

Transfer AC-In for delayed transfer opening {1199}

This configuration determines the voltage below which the transfer relay will open after a certain period of time. The Xtender will then run in inverter mode.
