To select a battery system, proceed as follows:
Selection of the 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 and use your own data records.
Determining the number of battery systems
A maximum of 20 systems can be selected. The number can either be entered directly, or the current value can be incremented or decremented. using the arrow keys.
|Installed Power||Rated power of the battery inverter|
|Charging power (U0)||Required charging power for boost charging of batteries in kW. Based on the storage capacity of the battery and the boost parameters (U0 charge) of the battery charging strategy|
|Battery||Rated power of battery inverter in kW|
|Load Peak||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||Nightly average consumtion of all consumer in kWh|
|Recommendation HTW||Recommended size by HTW Berlin |
|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.
