Selection of battery system

To select a battery system, proceed as follows:

  1. Selection of the battery system

    Selection Battery system

    Use the Companies and Model drop-down menus to select the desired battery system. With the button you get detailed information about the selected battery system. Alternatively, click the button to access the database of battery systems. The desired battery system can also be selected there.

    If the desired battery system does not exist in the database, you can create your own data records and use them.

  2. Determining the number of battery systems

Battery system information

Informations Battery system

Parameter Description
Installed power Rated power of the battery inverter
Charging performance (U0) Required charging power for boost charging of the batteries in kW. Results from the storage capacity of the battery and the boost parameters (U0 charge) in the battery charging strategy
Battery Rated power of battery inverter in kW
Peak load Maximum power of all consumers in kW
Usable battery energy Calculated from the battery voltage DC, the battery capacity C10 and the usable battery charge range (Maximum SOC - Minimum SOC)
Average consumption at night Recommended size of HTW Berlin [1]
Battery Usable battery energy in kWh
Average consumption per 24h Daily average value of all consumers in kWh
Maximum consumption per 24h Maximum daily consumption of all consumers in kWh

The electrical charge stored in a battery (galvanic cell) is called capacity.
